Boosted high compression, et's on 9 lbs?
 
Just wondering if the car would pull low 9's? 11:1 would limit me to single digit boost levels, according to the engine builder.. Thinking E-85 to keep it safe.. Motor is already built to the hilt. 402 with AFR 225's. I would keep it at reasonable levels, not looking to push it to the edge.. Turbo?

At 10 lbs of boost the car runs 9 flat.

we did an 11:1 turbo car last year. Tuned by Jim @ SpeedINC. Only made limited passes so far ironing out things and it has gone 9.36@147 on 10lbs w/ a 1.42 short time. The car has 600 street miles on it and we still havent had a chance to get the launch down. Should go low-low 9's on 10lbs, then we can start working up to the the 16lbs it was dyno'd up to.

If you plan on 11:1 + C16, if you got a proven head gasket setup turn that sumbitch up. 25+ Psi aint scaring me.

Sounds like low 9's wont be a problem..
