how much compresion can i run on my 383 with a intercooled pro charger running 8-9 psi

thanks shawn

 

how much or what would be best with only 9psi? If you are daily driving the truck id go with 9.5:1

 

not a daily driver ,but want to run pump gas

 

Same question for you Dan. 383/15psi on 93 octane. 9.9:1 too much? 9.6?

Daily driver

 

9.5 would be all I run with pump gas on that combo.. you are still going to see quite a bit of KR
Most pump gas is still oxygenated which in a f.i. world with too high Static C.R. is going to play havoc with the fueling.
