E85 Use
Has anyone seen any engine issues by using E85 for increasing Horse power. I'd like to use both don't want start fouling my injectors or plugs. I have a procharger and want to get a little more hp

I've run it a few times, and it seems like the benefits in our NA motors are negligible. I've gotten some that was probably closer to e60 and it was noticeably slower. For some reason the throttle was punchier, but it felt dog slow at WOT.
I've also got some true e85 and it felt about the same on my butt dyno as my 93 octane gas. YMMV. Since you're forced induction it could make a difference, I know e85 is great for turbo motors but I'd imagine it all depends on the tune and how much timing is being advanced, etc.
But no...no issues to speak of. These are built for ethanol so you wont have your typical corrosion issues and such.

The owners manual for my 2014 Eco-Boost 3.5L engine says to not use E85 fuel. Gas with 15% ethanol is the absolute max fuel alcohol laden fuel to use.
E85 is fine for any flex fuel engines.
