Finally ran this thing on the new turbo setup First off, some excuses. 
Still have these damn 4.10s in it and only had enough time to tune the 2 bar to 8 psi, which is about all I have enough fuel for anyways. But I got crazy and decided to run 9 psi instead. This is all just 91 octane **** gas.
With these 4.10s I am totally out of gear by the end of the track, so I just ran it out and left it in 4th until it hit the limiter at 6900 rpm and then coasted. Unfortunately this was right before the last beam in the traps. This gave me...
131.29 mph
The only thing I was happy about with the new setup on these first few runs was the mph. Picked up ~32 mph from the 1/8th to the 1/4. I have to find a 2 step, the 60' was not good. My ET was only an 11.3, the 60' was horrible at a 1.9. Bogged real bad coming out without any boost, and only made 2 passes and then called it a night and drank some beer instead.
Damn ricers were out in force tonight at firebird raceway, wasted 4 hours in the staging lanes to run twice.

What gears are you going to swap in there next? I want to get rid of my 3.73's pretty soon too.
Stoopid ricers and clogging things up....they are bad about that here too.

Damn, almost forgot about this thread.
I am going to swap in some 3.42s and hopefully Harlan will start building his 2 steps sometime soon.
I will be happy with it on 10 psi/91 oct once I get those gears in for a little while, then it's time to do a real fuel system and turn it up. I only have a single walbro 255 with a boost a pump on it right now and it's just plain out of flow after 9-10 psi.

Never got back to me on what the improvements are though...
