10-second, Full-Interior Evos That AutoX / Road Race?

Are there any 10-second, full-interior (sound insulation, radio, A/C, etc.) Evo owners who autocross and/or road race? What does your drivetrain look like in terms of mods?

I ask because the math seems to indicate that a 3500-lb car (including fluids, driver) needs about 700 whp to get into the 10s. http://www.tunercalcs.com.

All the dyno charts showing cars with over 700 whp on 91 octane gas seem to have torque curves that are very peaky and thus not suitable for anything but drag racing.

There must be a way to have your cake & eat it too.

Who makes 700 HP on 91 octane?

Why would you build an Auto-X car and leave it full weight?

Isn't somebody running 10s on the stock IX turbo with a "fully weight" MR though? While I don't think it would be a national Auto-X champion, I bet it would do just fine at the local races.

Not sure where you numbers came from because when I enter 3500 and 520whp your link spits out 10.98.
700whp estimates 9.96

With the right combination of mods and tune that is doable at around 500 whp. post your current mods and your target hp levels and people here will start giving you suggestions.

It's called a Z06

The power necessary for a 10 sec Evo from a 2.0L or even 2.3L means a big turbo = slow and late spoolup.

There are possibly two ways around this that I can think of: nitrous or adding a supercharger to create a twincharger system.

It can be done with just over 500. It all depends if the person can drive.

your calculations are wrong. you dont need 700whp to hit 10s. as for drivetrain, all you would need is a clutch that can handle whatever amount of torque you are putting down.

My car pretty much fits your criteria. I run SM class and do pretty well with the car. It's definitely a crazy ride (skitzo power), but it's a blast. I wouldn't say it's the best setup for AutoX, but it's manageable.

Thanks, Chris - I knew there was someone out there. Sent you a PM.

I'd have to disagree with this assessment as there are several stock IX-equipped EVOs out there running mid-to-high 10s with either E-85 or race gas and I'm willing to bet they would be pretty exciting on the autocross course as well.
