I'm thinking about changing my setup to a blower, engine combo now is a hke 396, 6.0 Iron Block, Eagle 3.9 crank, Scat rods ,Weisco custom nitrous pistons, Coated bearings, has custom mamo ported afr 225's with a port matched vic Jr intake, has the new accel 4500 tb, 60lb injectors, meizere electric race water pump, think its about 12:1 compression. What all do I need to change? I will prob go with e85 so what injectors and what else to swap over. Thanks for any help! Completely new to boost! I was thinking procharger f1r, f1x, or ysi

 

compression is high....

 

You can keep that compression but you will need e85+ meth or race fuel or keep tune very conservative. It will make great hp with that cr

 

On that compression you will be quite limited. It should make decent power but you will have to run E-85, Methanol (as primary fuel) or race gas, be limited on tune and possible boost. I would recomend a F1A for your combo as the F1R/X will be to aggressive and produce more boost then you can use. Have the heads been decked at all? Combustion chamber size?

 

No I don't believe the heads have been decked, I'm ok with running e85, I just don't wanna mess this motor up, have too much in it

 

man if i were you i would maybe install other pistons and sell yours if you could, thats super high to go forced induction street car

 

Yea it needs lower compression, its not a every day driver by no means, will be more of a strip car

 

then leave it high and feed it race gas? lol

 

I'd do e98 or e-85+meth dascorch is running some crazy high cr on his vette and seems to run great.

 

If your willing to run E-85 you have a few more options. What size is the combustion chamber? You could always go with a slightly larger chamber size, a little thicker gasket to drop the compression a touch. With E-85 you'll be able to run a little higher boost and with the higer then usual compression, it'll make pretty dam good power I think. A lot will be based on your tune...make sure you have a VERY good tuner and take it easy on the timing lol. Try to get some info on the heads....I think its possible!
