I don't know enough about how E85 runs cooler than 98, but the issue with mine is if I want more power (more boost) I need an intercooler as any more boost than I'm currently running starts to heat soak, even in summer + a few good runs you can feel the power drop off a bit. Would E85 eliminate heat soaking issues? or does the air need to be cooled before going in..? Would basically save buying an intercooler, and I could pump like another 5psi in with a new pulley + injectors only. (cos yeah, intercoolers are like ~5k for a decent one)
I guessing this isn't how it works though as I'm sure people on the ford forums would be all over it
