I'm not gonna push the motor to its limit of life. But I"m just wondering like about how much a motor with 9.3:1 compression can handle

Thanks in advanced.

(side note: I will probalby lower my compression a bit more but not aht much)

 

You will be fine with 9.3:1 compression. Im running 9.2:1 right now and plan on running about 25-30psi of boost when it is all said and done.

As long as you can control your fuel and timing and run good fuel when under boost, you will be fine.

Hell, you can even run pump gas with probably 10-15psi with 9.3 and just back the timing down in the PROM.

Good luck. Be careful!

 

i ran 12psi on pump gas with my procharger for almost a year and a half.....with the supplied inline pump, good gas, and tuned the FMU the car ran really good

i just wish i thought about replacing my aging 70k mile intank pump.

It died, i went lean, and the motor went BOOM

oh, i had a 3 core intercooler at the time too and no prom work
