We can get very close to that number on a stock LT4 blower with no cam on pump gas. You still aren't spinning the blower that fast, so heat is not as big of an issue as it could be. Ethanol based fuels do have a ton of benefits, but unfortunately it is difficult to run reliably in blends. If you are maxing out your fuel system with a blend, and you accidentally run more ethanol, you will end up hurting your engine.

With a DSX low side, a flex fuel sensor, and no other modifications, you may be able to get away with full E85, but you would end up at less peak HP than you could be on pump gas using the same amount of fuel volume.

Methanol can be a good route to go as long as you are up to date on maintaining the system. A professionally installed methanol system is not as unreliable as you think, I would just plan on replacing the pump yearly for peace of mind.

This mirrors exactly what I was told by Vengeance Racing when I was setting up my build.
