Default swapping from nitrous to a blower

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

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?

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!
