I'm setting up a FAST on a GN with ported heads, 75lb, 210 roller, PI 3200, TE63 with .82, V2. The car is a little doggy but comes on like a bandit above 15psi. I'm not sure if it's just the car or my a/f ratio incorrect. I have the VE numbers running within 5-8%. My A/F ratio goes like:
At 5 psi- 12.7
At 8 psi- 12.5
At 10 psi- 12.3
At 12 psi- 11.9
At 15 psi- 11.8
At 20 psi- 11.7
Do I need to richen it up some?
I have my timing real low. It's not MY car so i don't want to pop. Timing at 20psi is around 19 degrees, with 110 octane.
