Project Bad Penny - more changes because done is boring

[Steve1968LS2]

wait, almost 720hp on a natuarally aspirated LS? seriously?
I have to change my pants...

bigger cam and more lift would have been 750.. solid even more.. it's pretty crazy what you can do. Imagine the tall deck.

Just checked out the NW 102mm TBW throttle body.. pretty sweet, might pick one up.

on pump gas, with hyd cam, has decent street manners, and still gets decent mileage on the highway with OD....yup, that's sweet.

When I first saw the dyno plot, I was wondering if Steve had shoved a Magnacharger on top of her or something.

[ArtosDracon]

It's nice to see someone really pushing NA power here. The weight savings are incredible and you can really do a lot without resorting to power adders, most people just either don't have the budget or the patience to do it.

Congrats, she'll be fun, that's for sure.

I'm hearing up to 800hp with a single plane manifold and a wheel barrel full of money.. wait, better make that two wheel barrels..

Forget about the horsepower number......

662 ft. lbs??!!

You could open a worm-hole in the fabric of time and space with that much torque.

(and a very flat curve....to add to Tony's comment)

Hi Steve, new member here.

You've done a great job on your car. Go AND Show, the way it should be. EXCELLENT numbers from the engine, I'm sure it will be a blast!

I'm curious, what main bearing clearance do you run with the aluminum block?

Take Care,
Tom C.

I guess that would be a personal preference.

It's good that the torque is higher up the rpm band. Maybe give those poor ol street tires a fighting chance.

Very nice Steve..Thing is a monster..gonna be a handfull with your light weight..Just a hunch, but I don't think you'll be needing any more torque unless you plan on setting it up as a drag car. Your steet tires will hate you as it is! LOL

Yea, I didn't even need this much.. but the car with the 454 still seemed to hook pretty good.

Hard to keep up with you power adder guys ;)

No kidding man, I like the simplicity of N/A too but d@m even a warmed over cobra mustang is more than most N/A street cars can do anything with. When you are traction limited like everyone is on the street, you have to make it up on top end.

Yea but now you have the HP to go with your new combo! that was the only hope we (I) had. You're now knocking at my door with 750hp/650tq and alot less weight. your killin us (me) Not that you didn't already..

If I remember right, the 454 was 650ish? going to 720hp along with the tq--better keep an extra pair of shorts in the trunk. The pull is awesome...

BTW... IMO...go for the 750hp+..

I'm not trying to stroke Steve but I think he's got the ultimate power plant. All aluminum, fuel injected, hydraulic cam and a ton of power. As long as it will rev to 7k reliably. Ron's twin turbos add a bunch of weight and may make the car's balance tough to race. I'd opt for a linear power band for anything but drag racing. I still think the driver and car's balance play the biggest factor but having the most repeatable horsepower sure doesn't hurt.

goddddd damn Steve!

I'm right there with ya! I agree it is the Ultimate engine for what he is using it for!

I was looking at a set-up very similar to this before I settled back to the LQ9 and Twins..(I do like the twins..LOL)

WHY? Serious $$$$$$

Maybe I'll bring RSX out to Vegas when its done and let you drive..You'll be addicted too..

The car has the power.. the car has the balance.. it's the driver part I have to work on. lol

This was always my goal, but let's not get confused.. my **** comes out good mainly because I talk to really smart people, listen to what they have to say and then formalate a plan based on all of thier input.

Trust me.. it was tempting to go tall deck with a huge solid cam and make 800 but why.. except for the challenge of doing it's a lot like having a 20" wang.. fun to brag about but most is useless.. lol

I found a 102mm TBW throttle body this weekend.. going to do a back to back dyno test to see what the gain would be. Chassis dyno tune should be next week.

Yea, thankfully I have a job that lets me indulge in my crazy impulses..

I could get a blower really cheap, but I just cant get myself to hang a hundred + pounds off the front of my car.

And we all love twins.. right?

I don't blame you at all..I was in turmoil for months trying to figure out how I was going to pull off a non turbo'd car that can still achieve 750hp.. sell off a kid, kidney? Got a wife for cheap..DOH.. LOL

[twosaturns]

it sure is exotic, but simple at the same time. it's like a classic Lola can am car w/ big inches and fuel injection stacks, or a '60's 12 cyl ferrari or lamborghini.
