Running an m20 on E85

[priapism]

It can and will corrode fuel fittings with continued use

It is better for the enviroment.

Seriously though the only reason to use it is for more hp, because you can run more advance. Word of advice though, buy it by the barrel with good QC, word has it pump E85 can variy wildly with its RON rating.

It is 105 octane or so, so that means you can run around with higher engine compression without knocking...??

Anybody here done it?

I understand you need larger injectors..? but why?

Engine temps are cooler I understand, and I am guessing one would want to replace all the rubber fuel lines if taking this seriously.

Lets discuss it!

EDIT: quick reading reveals that any rubber component in fuel system should be upgraded to alcohol friendly parts.
Also the ideal AFR with e85 is much lower, thus the bigger injectors (more fuel with same amount of air)

Basically, there is no reason to do it unless you are going turbo. All it gives you is shitty mileage and the warm feeling that you're giving money to one of the most overly subsidized industries in America.
