Andy, thanks for doing that for me! Your entered specs all seem fine, but there must be something weird in the blower details. I actually ran this motor on an engine dyno without the blower and it made a touch under 500hp naturally aspirated (peak rpm used was 6500rpm, and the power curve was still rising)
For the power peak to fall back to 5000rpm and only increase 70 horsepower with the addition of 26psi boost seems a litle odd.
The heads - I'm using a 2.1" intake. Does that affect anything?
I JUST FOUND IT!!!! You're choking my motor...... You've only givin me a 1.06" exhaust valve, not a 1.6" See how it goes when it can breathe
Whew.... you had me worried there for a while!
Thanks,
