I'm sure that you'll be watching everything close as ya dyno the car, but I am curious to see how your intercooler does. I've heard some good things about the treadstones (vertical flow) and I was really interested in seeing how your's does. I would appreciate it. Thanks Chris

With 14 psi on my stock 6L twin 70mm build I did 710 rwhp through a th400 and that was with 30% converter slip.

It will easily meet your goals I think.

Well the numbers are in and I couldn't be happier! I can't say enough about the crazy tuning skills of Mike @ Rapid Motorsports! Thanks again Mike taking the extra time to make things perfect.

This was at roughly 14psi on 93 octane. Once we did this pull, neither one of up felt the need to turn the boost up any higher

Ended up with 753hp and 706ftlbs. That is through the th400 and Dana60.

I don't think there's much you're gonna do with your WG other than dump them to atmosphere.

good numbers.

this is with STOCK 317 heads and STOCK corvette exhaust manifold right?

putting that out there to let folks know you dont need mega dollar heads or custom exhaust to make it happen.

was the final boost number 15psi? is that measured before or after the intercooler? thanks

Just clicked/scanned this whole thread... very nice work, you've got some skills to be proud of. As a Corvette owner I'm very jealous of all that wide open space you have

I'll have to check, but I'm pretty sure the IAT readings were 71* at the highest point. I'll go back and look at the log to verify.

He gave me the graphs, but they are in dynojet format so I have to download the viewer. The printer was broke on the dyno.

Dart 225 as cast = Flow, Intake: 290cfm @ .500” lift / 28”
Flow, Exhaust: 205cfm @ .500” lift / 28”

I mainly got them cause they were super affordable and have a thicker deck. Guess they seem to be working decent so far.
