I had changed out my head/cam from bone stock to a ported stock head with larger valves and added a larger roller cam (stock is a slider cam). The stock head config was making 230rwhp 325rwtq on 24psi of boost .. on 93 oct pump gas. Then I found out some impellers were missing on the turbine wheel. I put a new stock T3 .63 housing on it and when I installed the new head .. I just set it on there, backed the timing down to 8 deg, left the cam at 0degs, fuel pressure at a safe level (38psi), and backed the boost down to 17psi.
All the increases were gained by raising the boost (max was 20psi), while playing with the cam a bit, upping the fuel pressure, and intital timing. I'm going to need a better located intercooler (front mount) before I can start raising the boost more... and getting more aggressive with the timing. Still using the stock T3 and 100k+ shortblock.
Can't make it this weekend to Talladega - I have to work Fri-Sat-Sun. I'm sure some of the other SVO guys will be there though. Maybe you'll let them by this time on the straights instead of blocking?
