Aster bracket
twin 4.5" intercoolers

Just trying to see what I could put down for numbers. While I wait to get it finished. What do you think I could get for boost too?

Buddys C5 with a d1, 347 and 18lbs makes 850 to the wheels.

700-800+ depending on tune, fuel, and supporting mods and drivetrain. you can be in the 9's.

Question: D1, or d1sc?

Bob@BruteSpeed

It has to be a D-1SC, ProCharger never made a bracket for the D1 for these cars. Bob

D-1SC. drivetrain is a build t56 by tick, spec 5 clutch and moser 9" all bmr suspension

Easy 750rwhp+. You have some nice mods, so I wouldnt see why you couldnt crack 800 to the wheels. Which pumps did you get from Lonnies? 340s?

orangeTA

Yes twin 340s from lonnie

WTF?

The 800+ guys are over 10.1 CR, I think you'll be 650ish. The E85 will allow good timing, but I feel the dropped compression will hurt you.

This is my brother's car, we built ours identical except I have f1-a and front mount and Dan Schoneck's cog setup. I was kind of disappointed with my 735rwhp and thought the 9.0:1 compression was the cause of the low numbers but others did not think so. I spoke with Bob @ Brute Speed and emailed Tony Mamo and both recommended these heads for us. Any other opinions on the compression?

WTF?

I mainly deal with the corvettes and A@A or ECS setups, the D1sc's that put up the big numbers are stock compression, Meth, and NO belt slip around Max impellar speed. Compression is Key to performance vs a good dyno number that performs poorly.

Yeah your compression is pretty low with those heads and pistons. Its gonna make over 700, probably closer to 800.

You can get pretty aggressive with the timing since you are using E85 but Id think about swapping to a head with a smaller combustion chamber. Its free HP and your AFR's are worth plenty so you shouldnt be out any money

Got my car back and it made 606rwhp.

606??? Did they tune it on the conservative side?

How much boost?

Any photos of the how you mounted the big red bypass valve with the twins?

orangeTA

11 psi. I dont have one but it is right in the y where they come together.

Is the clutch holding? Seems way low!

jmp51483

Agreed. My stock LS3 with a D1 @ 9.5lbs made 660 / 590.

I'd have the tune checked. What'd the A/F look like ?
