How much timing are you running?

CRAIG24 deg max with no knock.

You definately have a bottle neck some where. Too bad you have a 2g, I would send you my 3" O2 eliminator with atmospheric dump. The angle of the recirculation into that 02 eliminator is not good. It comes in at way too steep of an angle. That is the only thing I could see in your system being a problem. The Greddy FMIC isn't huge, but should be good for more than ~460 whp.

You are still putting down some good numbers, I am not dissing your setup. I am just trying to help get even more out of it.

I'm thinking some of it's from the turbo. It's basically a GT30 .56 trim 55 lb/min in a Mitsu style exhaust housing (copy of the L2R). I'm starting to think the exhaust housing is choking it down.


I'm still working the on tune also. My fuel logs showed a change since I got those boost leaks fixed. It's close, but I think I can get it better.

He is in a full weight 2G also, so you have to consider that he is probably something like 400lbs more than what you 1G guys are used to, thats a few mph right there. Also, maybe that turbo isn't quit cracked up to be what we would expect, what is the exhaust housing on it like? A 55lb/min comp wheel should perform a bit better than a 50-trim, but it seems to be performing about the same. 28psi on a 2.4l motor should just about max out the flow capabilites of that turbo, but it still seems a little bit down on power. With a 122mph trap and the wieght of the car, I would guess the car is putting down somewhere around 460fwhp, but I would have expected that turbo to be able to push a bit over 500fwhp at 28psi on a 2.4l.

I was thinking he was down at least 50 whp too. This is the only thing I could see as a possible bottleneck in the system (besides possibly the turbo).

The air from the WG is coming it at a really nasty angle and is probably really hampering exhaust flow.

PTE GT35R

Either an AlienAuto or VPE tubuar manifold.

AlienAuto? Do you have a link to them?
