I recently had my engine retuned for E85. I had been running 113 octane race gas. I used Bosch plugs (BKR7E-11) with the race gas. With E85, I assume that the engine is running cooler. Should I be running a different heat range?
H22, fully built, Arias 10:1, MSD Digital6, GT30, Coolingmist methanol/H2O spray triggered @ 8psi, 3" exh., I'm using 10 psi and 17 psi settings. Seems to run fine with the 7s but I'm not aware of what plug readings on E85 would look like. 439 whp @ 17 psi

Anyone with experience on this? Also, should plug gap be changed? I have it set at .28.

Anyone with E85 experience? Generally will plugs used with E85 need to be a hotter range than those used with gas/race gas at the same boost level? Any gap difference?
