There has been minor progress on the car in the past week. They are finish whiny up the rear valance. The mods made from the last update were to increase the size of the verticals ridges, recessed the center section and extended the valance back to be flush with the gas tank. They are finishing up on the exhaust ports now. The exhaust will be the same oval shape as the tail lights and the opening will be 1/4" larger on all sides. It will involve creating a lip in the balance for additional depth and visual appeal.



I should hear back from Ron Sutton Race Technologies regarding the suspension analysis anytime. Overall, the suspension appears to be good but improvements can be made. The rear suspension on the original car simply won't allow me to provide enough traction. My plan is to eliminate the upper bars and add a torque arm. This will force me to remove some of the bracing from the bottom of the car (glad I put a cage in it already). I will have to fabricate new supports and likely change some items with the e-brake. I won't start that project until after I get the car back from the body shop. The car should have better acceleration, handling and braking. A win win win.

The front will have a couple changes. The changes will require me to trim a little here and there from the original structure of the car to ensure I am getting the most out of it. I haven't seen the final analysis but it sounds like I will move the lower coilover mount out about an inch, changling the height of the lower control arm mounting point as well as adding longer upper control arms. The last one will require the trimming. We are also evaluating using Wilwood spindles for better KPI and using custom steering arms.

When it is said and done the car should be able to hang with the best of them on a race course and at the car show. I can see why Swedish Ops designed the suspension they way they did. To take it to the level I did you would never be able to go back to a stock setup again. It would require a massive amount of body modifications that almost everyone would not be willing to do. I want this car to be the best it can be and don't plan on compromising on much to get there.

wow it has been a while since I have looked at progress, looks like your moving right along! love the body mods and the nice tight cage work! keep it up it will be done in no time!

[Peanut1959]

Tapatalk needs to learn the term "valance"!

Well, hell, my autocorrect tried to turn it into "balance", also!

[68EFIvert]

LOL! I fixed the spelling error. I guess I need to spell check the auto correct feature!

The exhaust holes have been made into the valance and the drop down panels are in. I also added a tow hook that is removable. It tied into a boxed in frame rail. Once removed a filler panel/bolt will go in to cover the hole.






The license plate is about to go in. It will be flush on the bottom and recessed on the top. The corners will be rounded and a trim piece will go from both sides and on the top. The trim will be removable and 1/4" thick and chrome plated. Basically the same as the trim around the tail lights. The sheetmetal on the outside is to keep the panel from warping while cutting and welding the license plate



Next up on the rear will be fitting the rear bumpers.

My goodness......How old is that creeper!?!?!?!

[RMMiller]

That's fairly modern, I have one that has cast brackets for the steel wheels my grandfather used in the 40's/50's.

Really, no kidding!!
Looks like a solid unit, for sure.
Sorry for the OT.
By the way, I work at a Volvo dealership, so I show my dudes in the service department your pics.
Thanks man!

[Dragonfly]

great work , nice unit

[68EFIvert]

The recessed license plate is now in. Only thing it needs is the trim that goes up the sides and across the top.

The latch assembly can now be installed.

This car is looking amazing! I can't wait to see the bumpers.

[68EFIvert]

Thanks for the compliment. The rear bumper is coming along. It started out on a 1963 Corvette but has gone through massive modifications to work on the Volvo. Still has a bunch of work to go but it is starting to take shape. When this is done it is back to work on the nose of the car.

[Peanut1959]

Nice choice of bumpers! Really suits the car (post modification, of course!).

I just received the suspension results back so I wanted to give an update. As I have mentioned in the past I had Ron Sutton of Ron Sutton Race Technologies perform the analysis. There is some good and some bad. I will start with the rear. The rear suspension is very close to what the original car had other than coilovers. Link locations are very close to the original car but neither is good for planting power to the ground. I am planning on making some pretty serious changes back there. I am going to remove the upper links and add a Torque Arm. This will improve traction, handling and braking on the car. I won't go over the details of specifics but it will make a bid difference on the track. For the street or occasional auto-X it is fine.

The front suspension has some challenges as well. The upper control arms are a little shorter than optimum. This causes a couple issues. The roll center is not as good as I want and the Ackerman leaves some to be desired. According to Ron the front suspension works for a street car, auto-X setup and daily usage but isn't optimal for track use. Basically fine for the average guy that want to enjoy his car and not want to modify the entire front clip in the process. Much of the problems are a result of the narrow track width of our cars and the fact that the kit is designed to be a "bolt in" piece requiring minimal modifications.

As it is the front is functional but not for my intended purpose of the car I am building. I want a car that has good road manners but will also dominate on the track. I will be the limited factor to the performance of my car. I know that most people won't care to have the ultimate in handling on an 1800 but I am the type of guy that if I don't do what I feel is best from the start I will regret it and eventually redo it at a much larger cost. I have hired Ron to design a front suspension that will have no compromises. Every component on it will be the highest quality and designed for optimization.

The front brakes will still use 14" Wilwood brakes and a splines sway bar but everything else will change. I will have to have a front clip made and it will be welded to the chassis instead of using a bolt in crossmember. It will require a massive amount of surgery but I can honestly say that in the end I will have the best handling 1800 around. The front tire width will be increased to 315 tires so that I am running the same size on all 4 corners. I will keep the exiting 275 front tires for daily driving but have another set of matching front wheels/tires for track days. When is is all done the car should be able to take corners at over 1g. Here is a picture of the same basic design but is for a Cuda project and is running a 335 front tire. As you can see a radical redesign and will require the car to have serious modifications.

With all that said I will be selling my existing suspension to someone who wants to cruise around and have some fun on the auto-x. If you are interested let me know.

One interesting thing that Ron told me was regarding OEM's and what they put out. I think everyone would agree that a Viper is a pretty awesome performance car but the rear suspension leaves much to be desired. The geometry of the rear suspension is far worse than the front suspension I have now. When the analysis was brought back to Dodge so that they could fix the suspension for a track car Dodge told them there was no budget for it. So they ended up putting 1400 lb springs and a 1100 lb rear sway bar to make the car handle! Basically if the geometry is way off make it stiff as hell so it can't move. LOL!

Looks like it was inspired by pininfarina. Has an mid 60s GTO Ferrari feel to the mods

[68EFIvert]

That is the general look we are trying to get to. Here is a picture of the front as the body shop begins the modifications. The 1970 Camaro split bumpers should look pretty sleek. The lower valance is starting to take place. The curve on the valance is almost exactly to that of the Volvo sheet metal. It should make for a smooth transition.

The amount of modifications passed the staggering category many pages ago.
Kudos on all the progress, the car looks amazing!
Bonus points for the prancing Moose !

[Bozeforged]

Looks great Darreld! Glad we could help with the wheels.

Thanks

[68EFIvert]

Thanks for the compliments guys. I just hope it is done by next fall and if I am lucky can find a place to show it at SEMA 2017. With a bit more luck competing in an optima event in 2017 or 2018.
