E85 Injector and fuel pump sizing I am planning on ordering a forged short block and reusing my AFR 205 heads and LS6 intake with XER273HR 224/230 .581/.588 114 LSA. I will end up with about 9.5:1 compression with the intention of buying a Pro Charger at some point mid to late next year. I intend to run somewhere around 8-12 lbs of boost. I am having trouble figuring out what size injectors and fuel pump I would need.
1. If I wanted to run E85 what size fuel injectors and fuel pump would I need?
2. Could I buy the large enough fuel injectors and fuel pump I need for the Pro Charger now?
3. Should I wait until I get the Pro Charger to upgrade the fuel system?

80 lb injectors running at 58 psi base pressure will get you to 600 easy and 700-750whp will be pushing them to the limit with e85 . As for pumps twin walbro 450LPH will be more than sufficient.
