Hey!,
What AFR do you guys shoot for at the various boost levels? right now i'm running 12:1 at 8psi and plan to richen it up to about 11:1 at full boost (15 psi), hitting 11.5:1 at 12psi or so. Does that sound reasonable? My timing at 15psi is about 15*BTDC and at 8psi it's at ~20 BTDC.

The car is a 1990 TII with a rebuilt stock port motor, and i'm running a 60-1 turbo, 3" exhaust, FMIC, etc. Intake temps haven't gone over 110*F yet (12 psi), so it's pretty cool.

Thanks!,
Manolis

 

those sound good. i am running 32deg advance at 0psi to 14deg advance at 15psi and my afr's are:
11-12.5 up to approx 8psi
10-11 up to 17psi
