can i boost high compression?

skuba · October 11th, 2009, 07:03 PM

i got a 98 gt with forged high compr. pistons. would running boost hurt my motor?

acmillr · October 11th, 2009, 07:05 PM

What are you referring to as "high compression"? Anything under 10.5:1 will handle SOME boost on 93.

10.5 : 1. is what i want to get so ill be fine running about 8-10 psi? if not how much compression will be good with boost?

You either want high compression OR boost. Choose your fate

i'd only run about 6 lbs with that, not 8-10.

You'd have to run 100 octane all the time if you run alot of boost.

You said you have high compression then you said you want high compression. If you don't have high compression yet and you are gonna build a motor and put boost to it then go with lower compression 8.5:1 or 9:1 with forged pistons and boost the hell out of it is what I would do.

if you are going out of your way for a built bottom made for boost, then get 8.5 to 1 and run as much boost as you feel.

boost gets you laid

Sure dude, high compression with boost will make gobs of power, but you can rule out filling up a the pump.

imo 8.5-1 is too low well depending what blower your running ... i would run 9-1 to 9.5-1 but I wouldnt be looking for much higher unless you want no timing and or have to run race gas
