CAMARO6 - View Single Post - Question about pulley size/ boost amount on a Magnuson 2300

I just joined this site as there seems to be a lot more technical info compared to corvette forum, especially concerning Magnuson blowers specifically.
I’m looking at buying a Magnuson 2300 (maybe the R model if it comes out before spring/summer) for my 2016 Z06 M7 but I’m wanting to know which upper pulley I’m going to need and was wondering if someone could help me out here. Quick run down with my mods are: Innovators West 18% lower pulley, dual nozzle AlkyControl meth, low side fuel system, stage 3 Vengeance Racing cam (32% fuel lobe), 2” ARH LT headers w/no cats, Corsa exhaust, 103mm TB, Halltech CAI...so basically the car made 740 RWHP with a factory ported blower with a factory upper pulley (18% lower pulley though) running around E50 fuel, not sure about what the boost was. My question is, what size upper would I need to run when I buy the new Magnuson to maybe hit 800rwhp, and what boost would that equate to roughly? Having this lower pulley is kind of throwing a curve ball at me. I don’t see too many LT4’s on CorvetteForum running a Magnuson WITH a 18% lower so I don’t know what to expect, I want more power obviously but I don’t want to out do my fuel system either....any kind of help would be much appreciated.
