Since you haven't answered it yet, who tuned the car for you? Or did you tune it yourself?

And on the topic of the max boost at the track, it will often be different from what you see on the streets, especially with smaller turbos that taper boost. At the track, you will always be in the upper RPMs (after 1st gear), where the smaller turbos won't flow enough to hit that same level. For example, on the stock turbo, I would only see a max of 22-23psi after the initial 1st gear 28psi boost spike.

Also, just as another data point, I ran 116.6mph trap speeds on the stock turbo and cams (E85, no significant weight savings, IX MR). Your low trap speed definitely seems like it is tune-related.

The guy that tuned he's car is a really good tuner...I went 12.2 at 116.8mph on my stock 8 turbo,stock 02, stock mani, stock ic..... I'm pretty sure the tune has nothing to do with it.... you also have a evo 9 so your passing the quarter in 5th gear right??? Why not up your rev limit so you can pass it in 4th

He shouldn't have to shift to 5th if he has the rev limiter set slightly higher (i.e. 8k rpm). I was reaching 7,800 rpm trapping 116mph with the shorter-geared 6-speed, so 4th gear on the 5-speed should be good for a 120mph trap speed.

work on your driving.. you can shave 2 tenths off your 60ft easy

116mph is more than enough to get you into the 11's

It is a local tuner who has done plenty of Evos and a ton of other rides with much success.

Im on stock springs/retainers. So i didnt want to raise the rev lim on these cams.

While this may be true, the fact is that these mods should put me in the 120MPH range easy.

The OP trapped 113, not 116. And yes, he could hit 11s with that trap, but his MPH still seems low for the mods/boost, especially on E-85.

You should also be building more boost with your 2 step. I build 10lbs.

yea i am. The thing that is clueing me off is the 2 step. There is something going on other than a gearing/rev limit type issue.

I have a red and my 2step is in 6750rpm, I make 10psi of boot and a perfect launch.

Nothing lower in the 2step, works well for me.

What elevation are you at? What RPM are you shifting?

Do you have your power curve chart you can post?

That setup is capable of trapping 120+

2389 feet. I shift just before 7.5k stock rev lim. I need to get me a tactrix so i can start logging. I don't have a dyno for my current tune. It was road tuned.
