haha we need a sarcasm button. I have never seen oxygenated fuel so i have no idea there but the burn isnt cooler and if anything could even be hotter since higher octane means a higher detonation threshold.
I am building a 100% pump gas burning engine for my shitbox this time around. the little bit of performance that i got by pushing it didnt outweigh the cost, especially when at little sahara. I was even mixing it 50/50.
I always wanted to build a e85 powered banshee when i lived in nebraska but here in NW OK there is no such thing as ethanol in any gas.
