Not sure yet...depends on how it hooks with my PVD coated stockers running the 305/35/20 555r. Might do a Forgestar 18x5 17x10 setup.

No I don't...it's been on E85 for a while. I know Brett(Pray performance) Just did a Whipple @ 9psi on 93 octane and it made 586/550 with a manual M6 car with LT4 fuel system. Keep in mind mine was done in 5th gear so the numbers would be 25-30 higher in the 1:1 6th gear. E75-80 should add a good 50whp over 93 if you have the fuel system to support it. We really only need to run E50-E60 to get all the benefits of it. I just had it in my mind that I wanted to pull up to the pump and not have to worry about mixing.
Based on my research and what my car did. The LT4 injectors, LPE DI pump, and ZL1 low side with JMS is good to 8-9 psi with E80 without needing a Cam. With E50-60 10-11psi maybe possible. I might venture down that road and see if I can go to a 3.25 and mix down to E60 next season.
Weather forecasters are calling for some of the coldest air in recorded history next week, so the car wont be coming out for a good while. Next Wednesday shows -6 for a high and -16 for a low not factoring wind chill.
