air fuel blues!
Okay so I got everthing back up and running on the corvette. I installed a innovate wideband to see whats going on. I have a 383 procharged small block with 8.4 to 1 compression with about 30 degrees of timing. My idle is about 12: 1. My cruise is about 9.9, 10.2:1. When i got WOT it drops to to 9.3 to 9.5:1. I know i have to lean it out to about 11.5:1 but how much power loss can you expect from running that rich. Where talking about a motor before the blower was at 400hp, then added 12 lbs of boost to it. It really doesn't feel like it should.
Holley HP EFI, Procharged D1SC, 383 Dart Little M block and forged internals. 15.5 psi on E85! Chromoly Fab 9 rear end with Strange Pro Iron center diff, 3.89's and a Chomoly 4 point roll bar. Yes, its still a 4 speed car!
