fuel system ain't cheap, but yep, that's the route I took. 11.5 is good upto around 720 ish RWHP on 93 octane, after that I'd go 10.5 or even 10.0 depending on the type of racing. I'm actually at more boost than I wanted 10.5 PSI on a huge (slow turning pulley). The centri likes the 7250 RPM shift. I already tuned it on 93 and E85 or I'd go to an even bigger puller like 4.6 or 4.75 (if they even make one that big). I'd like to keep it at 9 PSI on 11.5 and 93, but maybe I'm paranoid, the car has very little knock retard and probably more a resonance issue anyway. I'll keep an eye on it. Injection window is good and to me that is a huge issue (did a lot of diesel racing).
