I have a stock 2005 evo. I have challenged a friend with an older Corvette to a race (at a drag strip, of course). I had a couple of questions.

Is there any benefit to icing the innercooler/intake between runs?

What rpm should I shift for maximum acceleration?

thanks

Stp - I too have an 05. And I came from the Corvette camp. What year Vette? C4? C5? If its a LT1 C4 you should have him. If its a LS1 C5 you should be door to door, and that would be a good race.

I do not, I usually dont hot lap either. Run a lap, park for a few, then go again.

With a stock 05. I would shift at 7000-7100 (my shift light set to 6800, so by the time I react it is 7000). Anything more will be out of the turbos sweet spot. And use your 5K limiter to launch.

Thanks guys! LT1 C4 I'm pretty sure all stock.

Anytime. C4 - ya you should have him. When you get those win lights, just be sure to remind him you have about a 1/3 of his displacement

Good luck, and happy racing.

I agree you should beat him, what mods do you have?
Whens the race? Keep us updated?

Great comprehensive answer, gj.

I would disconnect the 5k rev limiter. Rev it up to about 6500, let the clutch out just enough the car starts to roll and then dump it. At 5k your going to drop it on its nose or burn up your clutch.

I would disagree. I can cut low 1.6xs with the 5k limiter on. Just take out the slack in the clutch and on go, walk it back then dump at the end of the clutch throw. I do have an ACT clutch, but my stocker was the same process (I took the stocker out because I didnt like the feel. Its still sitting in my garage.) You are also building psi when you are on the 5k (I know you can flutter the pedal to get psi on 03/04s but its more work.)

ya you are fine at 5000

Smike, low 1.6s on the stock clutch with the 5k limiter? I don't ever remember you doing that or anywhere near that. I highly recommend he not try to do it on the 5k limiter, because he will have no idea how to properly modulate the clutch without burning it or bogging. 5k is too low for having no mods, stock clutch, clutch restrictor, and stock clutch line. He needs to disconnect it, and launch above 5k - not 6.5k like saywhen said, but somewhere around 5500-6000. The rest of the advice is good.

The whole icing stuff is irrelevant at your level of mods, but may help a tiny bit if it's super-hot summer weather.

Warr, correct, I cut low 1.8x to mid 1.7x when I was on the stocker. I was trying to make a point that you can do well on the 5k limiter - nothing more. The feel that I was refering to earlier was the pedal feel and modulation.

Ill revise my advice then - try both, see what works the best for you. And if you do go with the non-5k limiter approach, Warr's RPMs are best.

Warrtalon

Yeah, look back at your first try - you were doing 2.0 6's and running 13.6. You eventually got down to 12.1x @ 112-113 with only a few more basic mods.

If he has time, he should try both methods, but I don't think he'll figure out the 5k limiter on the first night.

And the very next time out I ran 1.84 (not posted on evom). There is a learning curve. Lets not start the comparo of who is better.

Warrtalon

I wasn't comparing who was better. I'm saying that if he tries doing this, he too will be running 2.0 60's and losing to that Vette. Even the 1.84 doesn't cut it, as you know, and that was on your 2nd trip. He just has this one chance, so I think he should use the 5k limiter.

For the record, I didn't even know there was a limiter when I first took my Evo out in stock form, and I did two straight 2.4s when the car completely died after the 2-step kicked in just as I was trying my feather launch. I basically rolled across the start line with the car shut off, then had to start over from scratch. I still ran a 13.9 on one of them, but I thought the car was broken, since this was when 05s were new, and I hadn't heard of this limiter.

I did somehow manage to launch without activating the launch control (below 5k) en route to a 13.1, but it was still just a 1.92 60'. I sucked.
