You guys out there with turbo'd big blocks, what kind of ignition timing should I expect to see under boost? The combination that I have is a 451 with ported Eddy heads and 9.5 C.R., SMPI (Autronic SM2), wasted spark ignition (M&W Pro-drag 4 firing eight coils), and a water-to-air intercooler. I am hoping to run 10lbs or better on 91 octane. If I can't make 10lbs, then whatever it will safely run wil be my limit. Turbo's (2ea) are T3/T4's with 60-1 compressors. If there is any pertinent info I have forgotten, let me know and I will add it. What I am mainly after is what those of you who have your cars sorted out are running. Thanks for any info!
