That run was done at 19psi with a conservative 11.8:1 AF ratio on race gas. I had 23 degrees of timing at 6800rpms, which is why I say conservative. I think the stock bov was leaking a bit since I'm usually running 20-21psi. After the car cooled completely down(later that night), I was hitting 23psi.
Dave, you're right. I probably will go back, but only after a new clutch, a new bov, and some more aggressive tuning. I think 12.0:1 to 12.5:1 AFR will work well on race gas. In the mean time I'm going to hit a new semi-local awd dyno and do some hardcore tuning. I'm shooting for 290 whp on pump gas, without doing any other mods. }( I will be spending more time on nearby road courses and doing auto-x next year though.
