I guess it's a good thing it came up. For ease of getting on to tracks, getting the chassis certified would be a good idea. For what this thing will do, I doubt a funny car cage will be necessary. I am relatively sure you'll need a chute though, I've seen some very stealth installs, but can't give much advice there, sorry. Ricoch3t sounds about dead on as best I can remember as well.
Wheely bars I have seen done with four pins holding the whole thing to the frame, 5 minutes on or off and virtually invisible when not installed.
As far as slicks and drag shocks, I'm quite sure that this is either going to use on car adjustable shocks or will have separate shocks, and I don't think slicks are on the bill at all. Slicks are very hard on axles and transmissions.

I do believe you are going to have to get the chassis certified even for running 9's. I think you HAVE to have the parachute b/c the last time i read the rule it said something like
required for cars running an et of 9.99 or quicker or for cars exceeding 150mph.
.
I have not raced for a couple years, but I have been running mid to low nines, 143MPH to 146MPH with no chute for years.
Your right about the pin on shoot. I have pin on wheelie bars on my Just Bring It street racer, I did the wheelie bars pin on so I could remove them when I was street driving, but they look so cool I have never taken them off. I never put a chute on, but I might for effect if nothing else, LOL!
To add a little viewing pleasure. Here is a video of my Just Bring It street racer. We had a race here we called the No Bull Nationals. 45 Florida street racers all got together at a parking lot, cruise 30 miles to the track in traffic. We through all out names in a hat and lined um up. Only rule was you had to make it to the track without the follow (caboose) car passing you.
My friend Mark brought is alcohol injected 14:71 blown monster that runs 7.70s in heavy street. He had a extra fuel cell in the trunk filling the 20 gallon cell because 20 gallons was not enough fuel for 30 miles! He removed the extra cell at the track.
I get beat by a bumper, but I left on him, he spun, and I owned him till he came by at 179MPH! No score boards during this event, But my run was a nice very low, LOW 9 second run anyway and according to my tach 146MPH.
My Just Bring it car makes right at 750HP on Mike Norris dyno and weight 3450LBS
Anyway, was a lot of fun. I put JBI in one of my containers 3 years ago. Last month we pulled the car out of the tomb it has been in for 3 years. It will be up and running in a month or so. I miss it.
Enjoy me getting spanked.

Just a thought... These same pin locations can be used to mount a removable trailer hitch for the trailer you are going to need to carry all your equip to/from events. Its an idea I am working for my car. (not the chute part LOL)

but SAFETY is also a major part of this. it wouldn't be wise to try to run a autocross w/a drag setup, or a high speed run at the level of competition they are shooting for.Speaking of safety, another one of the engineers we are consulting with about the project is Joe Marko, of HMS Motorsports. Joe has decades of experience in racing restraint systems, and consults with many racing teams around the country.
He's going to help us with our cage design, seat choice and placement, and restraint systems.

This was the finals, I had to beat some fast cars that day and was set on kill all day.
I sat in the burnout box waiting for him to put on his 300' burnout show for at least 2 minutes. It was like I was racing John Force. Whoever is racing him won't even start their burnout till he is backing up, LOL! if I would not have waited my tires would have been cold.
It was a Pro Tree, all the yellows flash at once and 4/10s later green. So after his show then he rushed all the way into the lights, Deep stagged and lit both bulbs. So when I pre stagged, I had to roll in and be ready wthin a 1 second to leave. So I no sooner was in and 1 second later the bulbs flashed and 4/10ths late GREEN.
I left him so bad when his car spun all he saw was me running away, LOL! He just has way to much MPH though, I thought he sucksed the windsheild out of my car when he came by!
We are good buddies, but he admitted his starting line tactics almost cost him the race. He thought HE would be the one to leave on me. I was set on kill, just need another 100HP of spray on the big end!
Most fun I ever had losing!
I cannot wait to get it up and running agin. I got the fever BADD.

Thats cool, only reason I brought it up is when I was younger our older car dipped down into the 9's and we were told we had to put it on. we were only running 9.80's at the time around 143 144mph. Figured I'd mention it just incase.
On another note.. have yall done anything else yet? I hadn't seen any pictures since the rear clip. I check back here every day for more pics :pics2::scared:

Just a few cents here from the peanut gallery, And I am not knocking your building skills one bit because you are obviously a proven and skilled builder, but it seems to me, and please correct me if I'm wrong, that you are getting away from the original theme of the car when you have to remove and replace parts for street, drag, and autocross/road race.
Like I said, not knocking it, and I truly appreciate what your doing, but to have a car that could visit each of those challenges without replacing parts, IMO, would be alot more appealing for someone like myself to build.
There is no doubt in my mind that you will meet your goals but it seems to me the real challenge would be to build a car that could do all that you said without having to remove and replace parts for each venue.
No, I'm not the fun police, just a realist.
I wouldn't dis on it too much especially if all they may be doing is swapping tires, shocks/springs ( or airbags ). 5 years ago, Chad Williams had an 8 second Viper that all he did was swap tires from street to strip.
To me it seems like a '69 version of Hot Rod's F-Bomb. Problem is that Hot Rod took that car out, rubbed on the front end and the car hasn't seen daylight in about 2 years so it's never completed it's mission. Tsk Tsk

Not dissing project one bit. How could you not appreciate what Frank and John are doing for all to watch and learn. This is free suspension education for all to read. It's just not what I interpeted when it was first announced.
Besides, look at all the interesting responses my post generated.

We are not trying to hold out on you guys. I got slammed last week finishing a 57 Chevy for a Rock Star that had a hard deadline. Also we decided to change up the build order a bit and finish the shell before we install the suspension. I will get some pictures up but it will be the same boring building of the shell stuff we have all seen 100 times.

Suspension:
Since you are doing a modular rear setup. Have you considered doing a offset 3-link as well a centered 3-link. I would be interested in the reasons why the centered 3-link was chosen.
I am considering a modular rear setup on my car and running a centered and an offset 3-link and even thought about doing a torque arm brackets at the same time. Just to play with different setups and compare the benefits and compromises of each setup.

05-11-2010, 04:20 PM
Frank and I both believe strongly in getting the exhaust all the way to bumper, at least in a street car. Under car turn-downs and side exit in front of the rear tire are both loud and tiring over the long haul.

16 Pages and only a hand full of pictures... This build thread is becoming boring.. We want progress pics!
Your right. I have been slammed in the shop working on finishing 2 other projects that are leaving. And have not worked on Unfair.
AND, we have been waiting on something BRAND NEW and we got it today..............
Our 3.6L Kenne Bell blower is here! And it is crazy! These have already made 1400HP on 5.6 litre motors! We did some careful measuring, Welded some engine mounts to our body jig.
So to get the crank pulley behind the rack (allows us to lower the enige 2" more), and to get the motor low enough for the blower to stay under a 2" cowl, we are moving engine 8" from stock location. This puts the motor 5" inside the cowl. It also puts the front of the engine block behind the centerline of the wheels!
So we are moving about 85LBS from the front to the rear (170LB swing) which combined with our aluminum nose should put us at 50 / 50 with no driver.
We are also moving the toe board back and the seat back which will recreate foot well space. Also, the floor gets lower as you move the seat back from stock position, which will lower the seat and will help give back the headroom we sacrificed raising the floor. Also we will move our own body weight back about 4 inches which will move another 40LBS (a 80LB swing) from the nose to the rear when we are in the car.
Additionally, besides the 1 1/2" channel on the body, we are also bolting in the subframe with no bushing gaining another inch of body drop. So with 2 1/2" of body drop and 3" of suspension drop, we have a 5 1/2" drop on the front and 4 1/2" drop on the rear, WITHOUT compromising suspension geometry or travel!
We have other HUGE news to announce as it relates to the engine, but are in a quite period for a few more days. But it is a BIG DEAL with a BIG name engine builder we are super excited about.
Here are a couple pics we can share.
https://static1.pt-content.com/images/noimg.gif
We most likely will have to build a custom throttle body! The inlet is HUGE and we will have to work on a few ideas to get a progressive TB that will open a little blade for drive ability and pull open the big blade for Hail Mary performance!
https://static1.pt-content.com/images/noimg.gif
Tomorrow we will make a relief for the blower which needs to move back a tick over a inch from where it is sitting in this pic. It is going to look super cool when it is done. No worries about wipers, our new hidden delay wiper relocation kit (coming soon) gives us plenty of clearance.

The firewall and seat mounting will be by far the heaviest fab work, we knew that from the get go. but none of the fab is rocket science. Anyone capable of doing the quarters should be able to do the firewall.
The magazine story will discuss the engineered advantages and formulas for moving the engine back, but will also point out this is a elective thing we are doing. Well, elective for most............ because of our monster blower, it is a requirment for us. A good requirment, but a requirment none the less.
We doubt very seriously many people will use this is exact combination of monster blower and raised the floor, and set the motor back. Most will probably use a NA motor and not need to do any of this. Keep in mind also, If we would simply go ahead and use frame bushings (give up that extra inch of channeling), we could set the motor in the stock location as it would clear the rack then. but we like moving the weight back. And we will show you how we do it with no real trick tools.
ProdigyCustoms
05-19-2010, 04:22 AM
You guys are killing me!! Now you got me thinking about moving motor back. AHHHHH!!!
We will be providing a engineered formula and explanation in the story. But in fast math if you assume the lump, (motor and transmission) is 800LBS, and if that lump is 60" Long overall and you move it 8" your moving 7.5% of the weight from the nose to the tail, so 7.5% X 800 is 60LBS. So 60LBS off the nose and added to the rear is a 120LB swing. If the stock car weighs car weighs 1700LB up front and 1500LB in the rear and you have 53 / 47 weight balance. If you move 60LBS from the nose to the tail you get 1640LB up front and 1560LB in the rear, and go to 51 / 49. It is a pretty big deal actually.
Now if you lower that lump 1 1/2"...................
Like I said, the story will have lots of engineering explaination
ArtosDracon
05-19-2010, 04:50 AM
Vertical CG is the big deal here, if you drop your engine 1.5" you're easily lowering your CG by 1" which could easily be 5%, and will decrease the distance between your RC and your CG by more than that, which will change the roll stiffness significantly, which is very good! :)
parsonsj
05-19-2010, 04:56 AM
is this build starting to go beyond what the "average" joe can do? No doubt, but what Frank said. I would argue that this mod isn't that difficult, as long as one has a welder and a supply of quality sheet metal. Let me add that we intend to photograph and show how do it, provide the engineering behind it, and document the drawbacks to this approach. One casualty is the wiper motor. It has to move, and so we'll show you our approach to how we move it. The throttle pedal is affected, the A/C evaporator, wiring, etc.

Something to consider would be a C5 or C6 oil pan. It would give you alot more room to drop the engine another 3-4 inches. I know John used it on II much. You can even build a custom pan since you can basically build the frame around it. We have a similar situation with the 70 we are doing.
i like the TBI blade idea. Run a progressive actuator that functions like the variable tuner valves the some modern intake manifolds. Opens up a second sets of runners when power is required.
Looks good guys.

I look forward to seeing this car built and then not doing any of the things you set off to do. It will never see a track day, you will break it on the drag strip and it will be at Meacom or Barrett before it has been done for 6 months. Mark my words.

We will be providing a engineered formula and explanation in the story. But in fast math if you assume the lump, (motor and transmission) is 800LBS, and if that lump is 60" Long overall and you move it 8" your moving 7.5% of the weight from the nose to the tail, so 7.5% X 800 is 60LBS. So 60LBS off the nose and added to the rear is a 120LB swing. If the stock car weighs car weighs 1700LB up front and 1500LB in the rear and you have 53 / 47 weight balance. If you move 60LBS from the nose to the tail you get 1640LB up front and 1560LB in the rear, and go to 51 / 49. It is a pretty big deal actually.
Now if you lower that lump 1 1/2"...................
Like I said, the story will have lots of engineering explaination
Very cool, and definitely worth the effort. you should be getting close to 250 lbs off nose with aluminum block engine. Are you considering dry sump?
I'm hoping to see that thing handle like a slot car. 12" tires up front would definitely put that thing on top. Aero would be a good thing to think about. Maybe slightly tipping the nose, blocking the grill off, and bringing air to the radiator through the valance.
I would love to see that done so that I could see the trials and tribulations before I do mine.
PITSTOPUSA has some things I was looking at that can help with ideas and design as far as radiator cooling and spoilers.

A dry sump has been theplan since day one, we just used this block for mock up. Our buddy Tyler sent us a contact today for the dry sump.
As for cooling, I am building one of our monster radiators and fan set up with dual 16" fans so strong it will be propellar driven!
Right now the plan is to keep body mods to a minimum. but plans change on the fly.

Keep in mind we added the blower. We have not weighed it yet but it has to be every bit of 75LBS. And it is 75LBS on the top of the motor. So it is bad weight. So all the more reason to move the motor back and down.
But were are still losing a lot of weight with the subframe, aluminum body panels, and lightweight LS motor.
We put a bunch of weight right in the middle of the car tonight in the form of a T56 magnum we are using for mock up. the original plan was to use the flyweight Mcleod M800 but it looks like that won't make it in time. So right now it will either be Keislers new clutchless trans or Transzilla. But damn those T56 are heavy!

I hear you, thats why I stick with the Muncie. With a road course car weight and tires are everything. Horse power is a bonus but in my past experiences it doesn't sem to contribute as much as one would think.
Aero is huge though, especially for what your building. I temporaraly tried out a fiberglass hood awhile back with no substructure. At speeds of 65 I noticed the center of the hood bowing up. That right there made me think of when I was doing 140 at Thunderhill with steel hood and the front of the car was lifting, most likely due to air coming through grill and pushing up on hood.

05-19-2010, 09:44 PM
We most likely will have to build a custom throttle body! The inlet is HUGE and we will have to work on a few ideas to get a progressive TB that will open a little blade for drive ability and pull open the big blade for Hail Mary performance!
[/B]
What about a bypass with a valve for the throttle body.
ArtosDracon
05-20-2010, 01:33 AM
What about a bypass with a valve for the throttle body.
Like a 60mm IAC almost, that's a pretty slick idea actually. Could plumb it more like a wastegate. Not sure how you'd work TPS readings though. Unless you make it level with the big TB and use one TB shaft for both TBs but have a special gear set that opens the big TB late and fast.
John Wright

Hahahaha....I remember lugging my Viper T56 from the basement all the way across the yard a couple hundred feet to where I had the car......yup, heavy tranny for sure.
ProdigyCustoms
05-20-2010, 05:55 AM
We are going to need to figure something out. EmptyNest had dual 70 MM and the one thing I hated was you could not leave a stop light without raising hell. You touch the throttle and got this HUGE gulp of air and the car lunged. This will be even worse I think with one big blade. So were looking for ideas here but admitidly have not made any phone calls yet.
jp455
05-20-2010, 06:56 AM
Viper engines are big as well and have two simultaneous throttle blades which work well. Maybe make the throttle pedal linkage have a rising rate so that a lot of initial travel moves the blade a little and the last bit of travel moves it a lot. I remember Peter Wheeler (TVR fame) always said that TVRs had traction control...a pedal with long travel.
ArtosDracon
05-20-2010, 12:58 PM
Long travel on the gas pedal is good for rpm control, but bad for engines with wide rpm bands. Your leg gets tired. A dual blade throttle body with progressive linkage would be relatively easy. Basically you could use a linkage identical to a dual carb linkage, have the throttles mirror each other so the throttle controls are on the outside, run the tps off the main linkage instead of off the TB directly.
jp455
05-21-2010, 01:17 AM
That was actually the first thing I thought of, a linkage like 4 barrel carbs where the second two come in later. I thought it would be more complicated than my first suggestion so I didn't bring it up. Can't wait to see the final result though!
parsonsj
05-21-2010, 02:30 PM
Right: as was mentioned, we need an accurate reading on TPS since the car is fuel injected, and dual blades and custom IAC ideas all complicate that. I think we'll be looking for a DBW solution before long.
preston
05-21-2010, 03:15 PM
That inlet is huge enough you could almost weld up a mount and use a standard 4 bbl throttle body mounted vertically !
But yeah with the ease of DBW on the LS motor it makes more sense to do that, then you can control the throttle curve all you want, and makes it ideal for TC as well. DBW is from what I've researched the only proper way to do TC..
Unfortunately the only aftermarket ECU that does TC and DBW is a $4500 Motec box. Unless someone has hacked the GM stuff to do aggressive TC.
Glad to hear you are going dry sump, I don't really take a car seriously anymore that isn't. Once you lower the engine though, you start staring at the next link hitting the gound, the bellhousing and you start thinking about mini clutches. That's where I ended up drawing the line. A man's got to know his limitations and $4k carbon triples (for streetability) weren't in my game plan not to mention reverse mount starters (passenger leg room don't you know).
ProdigyCustoms
05-21-2010, 03:22 PM
Lucky for use the Quicktime bellhousing is not really low. And if we trim off the flange on the bootom of the housing we gain a bit more.

Yep.. location of weight is as important as actual weight..

I agree with Tyler if your going all out on the motor you might as well get the best dam oil pan pump set up available (Dailey Engineering) Bill is extremely knowledgeable and a great guy to work with. Be prepared to open your wallet wide, a complete set up from pan to tank will run you up over 4K. If you plan on running AC you will have to do a custom drive assembly and if you plan on tracking for long periods at a time order the air separator option to prevent oil from foaming.
Bill has in the works a oil pan to replace the stock pans on the LS7 which will maintain your present AC and no modifications if you care to wait. I choose not to considering we built the chassis around the pan specifications (deep pan version which is still less in height than most other after market pans) It is expected to be out in July.
Kick ass blower set up BTW

No budget, we are simply getting the best of the best materials to build the best all around car one can build. This is not a budget build. No cheap parts will work on this one. We are building a Supercar, and Supercars are not cheap.
With that said, $4000 oil pan kits are not in the budget either! We do have to keep in mind we are building something to run some track days, not the 24 hours of Daytona!
Cost, Labor? If you value R and D time. R and D time will be HEAVY. We had 100s of hours in it before we touched the real car. Labor hours will be very high. John, Michael and I have multiple long days in it already. Hours add up quick when there are 3 of us working on it. Writing 72 pages of tech in the next 12 months is a lot of hours.
We have goals, we are only worried about the goals.
We will add up the cost at the end.

The new Quaife is open face dog box on the gears and drive discs.
By all means this tranny in stock form will not handle Franks and Johns intentions on torque/hp.
ProdigyCustoms
05-23-2010, 11:06 AM
It is looking like a Tranzilla. We used a T56 Magnum I have for another project for mock up just in case.
The Transzilla Close ratio box has awesome gear ratios
2.29
1.60
1.21
1.00
.85
.76
Should run like a 2 stroke dirt bike with those gear splits. And should pull the double overdrive.

Hey Ron,
The picture of the trans I posted above was the first RWD trans I could find before I went off to church this morning... I didn't have time to download the actual one I was referring to. Here's their "Viper" model that gets used for road racing all the time. As you can see, it says it's rated for 750 hp. I'm sure there's quite a bit of "safety factor" built into that number... Off the shelf, they have a Viper bellhousing but when I contacted them they said they could produce any bellhousing for the major car brands out there...
If you go on some of the Viper forums they are using this transmission behind a number of twin-turbo setups with no problems...
Frank, I'm sure the Tranzilla is a GREAT choice and cost quite a bit less than this transmission anyway...

About the gas pedal: Michael and I notched the driver's side of the wheelbarrow to recapture as much space for that as we would. It was a balancing act to give us room for the header, foot space for the pedal, and room to get the bellhousing off the engine block without removing the engine ('cuz I expect a lot of clutch replacements, lol).
We'll see how it all works soon enough.

I think 540Hotrod on Chevelles.com and Corvetteforum is running a semi clutchless shift 5 spd G-force in his 9 sec 540" 67 Vette. It is still an H pattern shifter. If you want something that is trick and will take the abuse that maybe the ticket.

Not very streetable due to noise though. With the kind of torque you will have you could go old school and run a bombproof 4 speed with a 2.50 rear end.
Thumbs up to Jessica !

It is looking like a Tranzilla. We used a T56 Magnum I have for another project for mock up just in case.
The Transzilla Close ratio box has awesome gear ratios
2.29
1.60
1.21
1.00
.85
.76
Should run like a 2 stroke dirt bike with those gear splits. And should pull the double overdrive.
Here is a little live action shot for you guys. We are finishing the firewall and tunnel today for the next story installment. This was the heaviest fabrication yet, but we used some old tricks to be sure anyone could do it.

Frank have you considered using Getrag V160 Supra 6 speed? It's well proven transmission than can handle over 1000hp with out BS, I could never understand why guys with high HP bad ass PT cars still use T56 that can't handle more than 700hp one quick miss shift and it needs a rebuild. You'll twist the driveshaft into a pretzel ,snap axles and even break $1500 carbon driveshaft on a car with V160 and the tranny will just keep going.Just a thought.

That cobra is not invincable. Ryan Mathews narrowly(less than a second) got out gunned by the Cobra on the road course. The real problem is the autocross. It's just so damn light and stiff. Add the driver being a multi time track champion and it's a tough combo to beat. You can build the baddest car on the planet but the wheel man is more important. At least in our world. I've heard John has been taking some classes but these aren't Z06's. He's going to need some serious track time to get used to this custom car and all it's systems. Custom ABS, Traction control, ergonomics, crazy power, etc. That's the bigger obstacle in my mind. The car will have the capability to take on that cobra. Will the driver? I hope so....

Don't discount yourself John. When I went to El Toro I never would've guessed I'd run within one second of David Pozzi and Ryan Mathews. (I would've bought the BFG's to compete for the title) Sure I was on R888's but it was only my second road race. First being a miserable failure puking a power steering pump just as I got up to speed. I think your biggest obstacle is seat time in the new car. You've got to tweak that car to your liking and that's going to take a handful of events. I've got mine where I really like the feel. If I can just get rid of the need to pump my brakes for knockback, I feel pretty dialed feel and engine wise. We know the load lies on you. Frank belongs in the B main. haha

How much torque can those tranny's handle? Just wondering what a heavy rotating assembly, 800 lbs of torque and a 3500-4000 lb car does to the equation.

I don't know exact number, but I'm positive it can handle just about anything you can throw at it ,especially in a PT platform, it's a well built transmission. List price was about $5800 last year,Toyota has plenty of them.
I wouldn't hesitate to have it in a car even with 1500+hp .
Bone stock MKIV weighs 3486 lbs, there are 2900-3000 lbs street Supras ,even few guys that have 2700lbs cars, but no a/c ,carpet,e.t.c.

I'm sure you guys have already looked at g-force trannys. if not check it out. I ran a Straight Cut T-5 in my mustang and beat the hell out of it with no problems even after 2 years of 7000rpm dumps on the line it still performed no breaks. They may have something that will work for you guys.

We have TRUE bolt-in kits to fit Viper, Corvette, Camaro, and Cobra applications along with custom installation kits that allow for an even wider range of installations. With the optional G-Force mainshafts, these kits have the ability to handle approximately 1200* horsepower and 1000 ft-lb. of torque depending on the application
jp455
05-28-2010, 06:43 AM
Stefan, like Parsons said, its the input shaft thats the unknown...a plate to mate the trans to the engine is cake! But if the shaft isn't the same then it becomes a problem, and don't forget that a custom clutch will be needed too if the splines are different. Not extreme problems by any means, just saying thats most likely the main reason why more people here don't use that trans.
On the subject of choices its too bad that this company doesn't make a front engine/rear drive transmission.

I've used that gearbox and it works really sweet! The shift mechanism can be sequential but it still has synchros and all so its completely streetable.

Gotcha, Frank or JP could stop by Titan and talk to Nero or Bottle, I'm sure they have one they could let them borrow it to see if they can make it work, Titan is right around the corner. Worst case I'll let them borrow my spare tranny. The shaft is 14 spline, 1 and 3/16" diameter, I can snap few pics if needed

How about a input shaft measurement. And also input diameter and depth at the pilot bearing. We are thinking if the Gertag has a longer input then a T56, it will be easy to make a adapter and I am sure getting a clutch disc made with the correct diameter and spline will be the easy part. But if the input shaft is shorter then we get into fabing a bellhousing, bigger project.

06-08-2010, 03:29 AM
I'm sure theres a reason so I'll ask out of curiosities sake...why not change the rear end ratio to make 1st gear work? Too high a gear in 6th?
ProdigyCustoms
06-08-2010, 05:24 AM
OK, here is why.
The unit we are looking at is:
(1st) 2.29
(2nd) 1.60
(3rd) 1.29
(4th) 1.00
(5th) .85
(6th) .70
With these gear splits being so close it will sound like a 2 stroke motorcycle once it gets on the pipe.
RPM drop between gears are perfect:
1-2 shift 7000 to 5000 RPM
2-3 shift 7000 to 5600 RPM
3-4 7000 to 5600 RPM
4-5 shift 7000 to 6000 RPM
5-6 shift 7000 to 5800 RPM
With a 3.70 gear this gives us a 9.8 starting line ratio. A tennie bit tall for most cars, but with our crazy low end grunt, we need to calm it a bit anyway.
With 7000 RPM capability we turn MPH in gears:
With our 25.7 Autocross / Road Race tires:
63 MPH in first gear, meaning on MOST autocross we will not have to shift, BIG DEAL!
Will run 145 MPH in 4th gear, more then enough for the longest straights and avoid a 5th gear shift, Big Deal!
Our drag / Maxton tires are 28" so it will run:
158MPH in 4th gear, more then enough for our 8.99 pass at the drag strip, and no 5th gear shift at the last minute.
At Maxton mile it will run 225 MPH in 6th, easily covering our 200 MPH goal.

OK, so time to update. We have been crushed at Prodigy Customs finishing (4) projects, (3) 69 Camaro's all of which are headed to RTTHs for their debut. We also have been readying the Bull Run Racer for Bull Run 2010 with a new Magnum 6 speed and lots of tinkering, and Lucy is ready to kick much ass this year!
John has been working on the Isis System and plumbing of a absolutely gorgeous black 69 Camaro we are finishing for a member. This is one of the cars coming to Pigeon Forge. While we have all been slamming on the other cars we have been working out the final details and sources for Project Unfair preparing for the eminent thrash.
Tomorrow is a big day for the project. I am flying to New Jersey to meet with Pat Musi to finalize the details of our engine build. Our RHS Block is already at Musi's shop. Our Mast Motorsports 6 bolt heads are shipping this week. The national sales manager and my close friend Tom Razzanno (who's SB2 headed SBC 427 68 Camaro convertible we are finishing right now) will be at the meeting as Manley will be supplying their killer rotating assembly. With the bulletproof list of parts and Musi building the motor, John and I are very comfortable of our power goals will met and the durability of the monster. I still cannot believe we are building a car and Pat Musi is building the engine...pinch me!
John has our traction control system in hand and is working through that. Our Holley fuel injection is on the way to John (exciting stuff for sure).
Last week Michael got the rear clip / suspension in the car. The installation went really well. The frame rails fit the floor perfectly. This week Michael will be doing the tubs and outer body sheetmetal. Then Unfair goes to John who has boxes and boxes of header and exhaust material from Cone Engineering. We are familiar with the quality of Cone Engineering products as we used them on Larry's MotiV8tr. At John's he will be doing pre wiring and plumbing while we wait for our drivetrain to arrive. Unfair will head back to Prodigy in a few weeks for body / Paint and get ready for final assembly. Things are gong to move very quickly now so the update will come faster.
Here is some automotive jewelry for you

Yeah I can't believe there is no semi-universal abs system available to the aftermarket yet. The first company that comes out with that for < $2k will make some money. Wheel speed sensors seem to be the biggest problem but its not rocket science.
However the liability issues in the US are.
I'm starting to get excited about this car, even if it is a unibody :)
joemac
06-30-2010, 11:52 AM
If I were a stand alone/aftermarket abs manufacturer I would make a sensor that stuck in the valve stem like a tpms sensor. I think that would be the easiest way to do it. Wireless and hidden in the tire. With the cost of electronics falling more and more the wheel sensors should be one of the cheaper components.
It seems to me such a system shouldn't be that complicated really. It needs a control monitor and the motor. Wire it, plumb it and done.
silver69camaro
06-30-2010, 12:28 PM
Yeah I can't believe there is no semi-universal abs system available to the aftermarket yet.
There is, Bosch has had theirs out for a year or two now.
But, the system would need to be programmable (IMO) in order to work well enough to justify the big price tag - and that really drives the price up. Then you need some PC interface and software to communicate with the EBCM.
I'm using a Z06 EBCM on my car, but only because it's a good match. If a guy had a stock subframe with more front weight, different tire heights, higher CG, etc it wouldn't work as well and probably wouldn't be worth the trouble.

If Bosch comes out with a system even half as easy to integrate they would already be on to something! A project I was involved with was in talks with Bosch directly and to get all the parameters programed to make the system work as an OEM was a major pain! not to mention hundres of thousand of Euros. They wanted the car for many days of testing and tweaking and would not let us program the control unit ourselves....a major major pain!

I know when we spoke with them the whole tuning of the system was a huuuge pain. They wanted the car for several months to drive in all type of conditions, and the costs were insane! we tried getting them to let us use a Porsche 911 system since the weight distribution was very close, still no go. Not that its comparable excatly but its in the same league, the traction control from Race Logic in comparison was a piece of cake! Drive in a straight line for so many yards, make a u turn, drive back. Done! haha! Only want 5% slip instead of 10%...turn the knob. Awesome system really!

We have made some big headway on Project Unfair. The rear suspension is in. We made wheel tubs using a Art Morrison wheel tub kit. We wanted a tub that did not curve at the top of the tub and wanted full travel to the top of the tub. We raised the tubs 1 1/2" also. We made the outer tub fit the quarter as tight as it could and gained some space where the factory outer wheelhouse bulges in a bit. We also welded a 1/4 rod all around the wheel opening moulding and when welded to the outer heel house will be very a very smooth edge SHOULD a tire ever get close to it.
All this is to clear our taller / wider 345 / 35 / 18 drag radials which are almost 28" tall! We pulled the wheels off Michael's Monte and mocked them up at ride height, pretty fricken sick height with complete suspension travel. What a difference 1 1/2" makes.
The sheetmetal is all screwed into place and fits excellent now. The door gap looks wide in this pic but it is a camera angle, the door gaps are actually very good. Trunk gaps need a little massage, but all in all I am very happy with the AMD stuff.
FYI, we weighed the AMD panels and a pair of Golden Legion panels. The AMD are 28 LBS, the Golden Legion are 18LBS! BIG difference and you can feel it to. When we welded the bead on the quarters we go little to no warpage!
We are getting a set of those 345 / 35 / 18 drag radials mounted on Michaels Monte wheels, so I will mock them up on Unfair before putting back on Michael's car and post pics later.
It is starting to look like a car and I am getting really excited now.
John will now get it for a couple months and start pre wiring, pre pumbing, Making headers / exhaust.

Those look like my wheel tubs (done back when the car was on drag duty)
Coming along nicely!

Actually... they are exactly the same as the wheel tubs I used on II Much. 32" (rather than the 36" or 40" you typically see on drag cars) which really lets you push the tire into the body.
Morrison used to sell them, not sure if they still do. The ones you see had been on a shelf in my garage for 9 years -- I bought an extra set back in the days when I used to do everything 3 times, lol.

The car is very cool, I'm also following it in the magazine. How are you planning to have full travel when the frame rail looks to be 3" from the center of the wheel? Is the ride height going to be higher than the picture? I hope not.

There is a frame notch, but also 3" is a lot of travel.

After many Power Tour's I am more of a 4.5" of travel kinda guy. But yeah, you can get away with 3.

07-23-2010, 07:20 AM
We're talking about bump travel, not total travel. Bump travel of 3" is plenty. Most cars have about 2" of bump travel, and 3" of rebound travel for a total of 5" or so.

I was talking about bump only as well. Most of our cars that have 3" of bump in the back are on the stops a lot on the back roads that Power Tour puts you on. Here in Arizona 3" is MORE than enough becuase our roads are about as smooth as you will find any where. Just personal preferance to build in a little extra room. I've found the ride to be noticible better.
parsonsj
07-23-2010, 08:21 AM
Wow, that's a lot of suspension travel. 4.5" of bump travel implies 7 or 8" of total travel or so, right? What sort of shocks and spring rates do you run?
jp
PhillipM
07-23-2010, 08:35 AM
Well on the back of our Olds we are running air bags and I believe Afco single adjustables. On the Studebaker they are 7" travel Koni coil overs.
As for the bags the spring rate obviously changes per the ride height. I have'nt gotten that far on the coilovers for the Studebaker. I have a few spring rates between 250 and 500 to test out. Guessing it will be in the 350-450 range? We'll see I guess. I should also mention that I have a 5/8" bump stop in there also so the true bump travel is right at 4 and the rebound is right at 3.
parsonsj
07-23-2010, 08:55 AM
I ran 7" travel coilovers on II Much, but it was set up for about 2.5" of bump travel. I had a *lot* of ride height adjustability on that car.
The car is coming to me in a week or two... I'll post up what I find with the suspension travel.

90% of the suspensions we sell use 17" shock with 14" ride height which leaves 3" compression and 2 5/8 extension. This is pretty much industry standard.
Project Prodigy has independant suspension and 19" long shocks with slightly more then 4" of compression but show no signs of ever compressing over 2 1/2".

That would indicate a pretty soft spring rate, at least by pro-touring ride quality standards.
Wesley J
07-23-2010, 11:58 AM
I dont know the exact suspension detials of the cars you're refering to but one has to take into account shock geometry. A shock run at 30 degrees will show 3" of travel on the piston rod but real wheel travel wil be ~1/0.866 of that or 3.5". I know I'm splitting hairs here but as you compress a shock on an angle, the angle increases and actually amplifies the difference even more.

I hate to take up much more of this thread with this particular subject but I venture to say that our rear coilovers on that car are at too great of an angle. It has 500lb springs on it now on a C4 IRS system.

Correct me if I am wrong but they have done that with automatics. I haven't read the entire thread but from the last couple pages it seems you intend to run a stick? There aren't many cars running 18's in the 8's, I can't think of one stick car that has done that.

07-23-2010, 11:01 PM
We have no experiance with these 18" drag radials. To gain experiance I am setting my street drag car up with a set od 18s to learn about them while we are working on Unfair. I run 15" slicks on the street racer and know what it can do within mili seconds.
Keep in mind we will have a few hundred horsepower in the bag. Also, none of those other cars have drag race 4 links either. If it takes a 15" slick, so be it.

The C1 compounds available in Viper sizes (345/30-19, about same height as 335/35-18) are very very good, the Viper that ran them in One Lap a couple years back dominated all the track sessions.

Ahh, the ACR tire. interesting, same sidewall as the 335 / 30 / 18 on a 18" rim. And the exact same 33LB weight as the 18! And the 19" rim is only 1/2LB heavier!
I ran the 345 / 19s on EmptyNest but they were not C1 compound. Could this be another Unfair Advantage? Hum!

The ACR comes equipped with the Michelin Pilot Sport Cup tire, which is closer to an r-compound with an 80 treadwear rating. The C1 spec PS2 is the OEM tire on all regular (non-ACR) 2008+ Vipers.
There were some rumors floating around during One Lap, that the C1 spec PS2s were actually the sticky Pilot Sport Cup rubber molded as a regular PS2. Those rumors were never substantiated to my own satisfaction, but the mystery (and possibility) remains.

My buddy Frank just ran 9.3 with a 6.0 iron blocked 408 in a 63 Chevy II. That was spinning its ass off,on its first try. I will bet he will pull a 8.99 before it is all said and done. Thats on leaf springs with Caltracs. Cool little car, your goals are definitely doable, should be fun watching it develop.

So we made some real progress. I just proofed the sheetmetal story (article 4). The AMD panels went on really well and are easily worth the extra pennies.
After Michael welded up the body we had Bob work on the roof to quarter seems, wheel lips (We beaded the wheel lips) and smooth the drip rails. The drip rails are only roughed in, but for roughed in drip rails they look pretty damn good.
So this weekend I will do some sheetmetal closeout work on the rear suspension, finish the driveshaft tunnel, get it off the jig, install the subframe and throw some rollers on it. And then send it to John for the pre wire and pre plumb. John is excited to get to work on it and I am excited he gets to work on it, LOL!

LS Fest is a great goal...............2011
We were busy this weekend, moving along pretty well. We got the rear firewall done and 4 link closeout in. We will build block off plates for the rear inner quarters to seal the passenger compartment from the trunk as tight as we can. We want to be sure if we back it into wall we have time to get out!
If you read the Firewall story in Super Chevy, you saw we are moving the seat back 4" which with the driver in the car makes a 1% front to rear weight balance difference which is a lot when your easing down to a 50 / 50 balance. One negative about moving the seat back 4" is a pet peeve John and I share which is a LONG steering column sticking out of a dash. We really want car to recognizable as a Camaro, hence the limited body mods and a stock dash is required, but since we are moving the seat back 4 inches, we would end up with that dreaded Funny Car steering column. So Michael spiced 4 inches into the dash top to move the dash back with the seat. Then IDidIt will make us a column with extra length under the dash, and the column will sit flush against the dash as it should. Michael was tacking in dash when I left today, but you really have to look at it to notice it has been done. I love it. I will get some pics of the dash installed in the car tomorrow.
So now if we can finish the tunnel, it can go to Johns!
