hello guys, i'd like you opinion about this setup, it is a pro-charger F-1 A going with 12-15 psi on a 427 ci engine LQ9 stroker ,using pro-charger intercooler with methanol, rc is 9.5 right now, we're considering make it go up(about 10.0 or 10.2), of course we're using high octane fuel on track, here is the thing i'm not sure if a rc like 10.2 going with let's say 13 psi and methanol can handle 92 octane fuel, any input?? have in mind i'm 5500 feet above sea level. thanks

 

Higher compression ratios at your elevation are tolerated as the air is less dense. I don't see you having any problems at 10.2/1. Bob

 

good support there!

 

Thanks! Bob

 

How are you getting 427 inches out of an lq9?
