Have a perfect for both a high or mid 9sec car and an awesome road race car. when i mean road racing, i mean big open tracks not autocross stuff.

You would need some obvious changes to the front and rear aerodynamics of the car but with just changing that do you think you can do it or has it been done??

Im kind of trying to attempt this right now.

 

Moved to Motor Sports.

If you never have tracked, I suggest either a beater car first or retuning the car down a bit. Its more important to learn the line, racing ins/outs, braking tech, etc. first. Then turn up the speed.

 

I grew up racing shifter carts and have had some formal training on racing. i was just looking at what people thought from a parts perspective such as small breaks and big brakes, weight and power.

 

for a road race car you want aerodynamics, big brakes, quick spool with a lot of torque and a very light car. its not going to be the same as a drag car, but certainly a well built road race car could do a 9 i would imagine. i don't see the engine lasting long at the power level to do 9's though...

 

start with: built 2.0 (head, intake, block, cams, etc.), HTA3582, good suspension, good (big) brakes, better oilpan/oilcooler, ditch as much weight as possible.

then:
For RR - decent aero (at least splitter, wing, rear diffuser), conservative tune, run R comps on either 17" or 18" rims

For drag - ditch the wing, up the tune, run drag tires on 17" rims

If you can shift quickly and launch well, an HTA should put you into the high 9's. The built 2.0 can be revved out to 9K even for RR duty and 9.5K for drag racing.

First off, its spelled "Brakes".

There are many people here with multi-purpose cars. Daily driver/auto-x/road course machines.

Take it to the next level, and you can surely have a very fast road race vehicle that will be fast at the drag strip. Many of the unlimited time attack cars are race cars built with drag-race power. But, honestly, who cares about drag racing anyways?

 

My definition of drag racing: "It's what you do in between turns."

A 9 sec drag race car is going to be insanely scary fast on the road course. That's the reality, and most people don't have the skills to drive that fast of a car.

My car makes around 460 whp and is wicked scary to drive at the limit, because the limit involves gnarly speed through dangerous sections of my local track. I'm going to be building a cage for the car this winter because it's just too fast to be tracking regularly without one.

But if your local track is wide open with lots of run out, it's not as big of an issue. I used to run my car at Miller in Utah, that track is safe with good run out and not that hard to drive - I'd feel fine in a 600 whp car at that track.

 

not a 9 sec car will give you an advantage over the 11 sec it is your driving skill + handling.
so spend more money on handling and track time, and, let say stay in the 10-11 sec car range . you will be better off overall.

 

Maybe it'll help if you list more then just your engine parts. However, With that part combo dude, even with track experience, good luck getting decent times. You'll have to brake WAY earlier then most people on decent straights, and also loose time in the tight sections because of off-power spool delays, even with a stroker on a turbo that big. If you read much on here, you'll see the top time attack cars aren't ANYWHERE near a 37r in terms of turbos. You'll need to downsize that right away, then work on building the brake system based on your skill/weight/power/track/style/etc. More stuff to determine then peak power and tune....

If you've been in karts, you already know it's all about entry and exit speed, which you won't have in that setup.

 

Run it with no aero. Turn the boost down for the first event. You'll be fine.

Brakes- stockers work well just get good pads for track use and bleed the brakes

Run it. It's a capable car that you have seat time in. It still won't be faster than a shifter cart!

 

The suspension and alignment are going to be completely different from one place to the other. With that being said there are lots of race cars (pro) that could probably run 9's if they tried. For the drag strip you want the car high and softly sprung so it can squat, just the opposite on the road course.

But as mentioned, you'd better know what the heck you are doing on the road course with that much power. And it's likely you'll spend more time broken than running with 9 sec hp. Then there are cooling issues, brake issues, aero issues, etc. Of course you could always turn the boost down on the road course.

What is your road course experience? And FYI I bet you will not be any faster, in fact you'll be slower, with 9 sec hp compared to low 11's high 10's hp. All that power going to the wheels means lots of wheelspin.

 

I have a car that's doing dual duty, and its about to be even more so as Pikes Peak continues to get more pavement.

The car was orig. built as a rally car:

TR30R turbo & restrictor
2.3L AMS Stroker 10:1 with Tomei 260s
Ohlins Rally Suspension
AMS Rally Brake kit
beefy aluminum skidplate

Then, for Pikes Peak it morphs towards a road race car:

HTA35R turbo
DHP Composites splitter and rear wing
OEM brakes
widebody front fenders
17x9.5" wheels

I'm actually thinking of taking it out to the 1/4 mile track sometime, just cause I'm curious...and I keep getting questions like "how fast does it go?" or "what does it do in the quarter?"

With the parts in your signature (37r, 280cams), I'd probably say you're tilted more towards the drag setup, but a cam swap and a slightly smaller turbo would be alot of fun on a road course. From my limited experience with my car on a road race track, I can say 500+whp is PLENTY to have some serious fun.

Dave if ya need a driver for the drag strip, I'm just a plane ticket away!

 

I road race a nine second car (not an EVO) and its a blast. I used to drag race all the time until a couple years ago when I got bit by the road course bug. I started out with the EVO which is a great dual purpose car, it pretty much does every type of motorsport well. After a while I swtiched to the Z06 and haven't looked back since. nothing like chewing them up on the straights and spitting them out in the corners.

Unlike in drag racing power isn't the end all be all when it comes to road racing. it helps don't get me wrong, but its not the first place you should be looking if you want to be fast.

The more power you make the more heat you'll generate, so you'll have to overcome that problem. Then there is teh fact that you'll be traveling at insane speeds and need to slow down ALOT, so the brakes will need attention too. I would say give it a shot and upgrade/swap parts as needed. Everyone said you would never be able to track a 700whp car but so far thats exactly what I'm doing and loving every minute of it.
