Premium unleaded to e85
I have a 700 horsepower engine in my 08 z06 N/A. Just wondering if I upgraded fuel system switched over to e85 and got the vehicle tune. If there would be a increase in horsepower?

This is asked quite frequently so I suspect you can find many more opinions than mine. Unless you're running some crazy high CR, the performance increase will be negligible. If you're curious, you could re-tune on race gas to see if your combination is knock limited already on 93 octane. If you don't pick up much on race gas, E85 won't be worth the effort.
BTW, 700 rwhp is really hard to do N/A so I suspect you're giving us flywheel numbers? Is that correct? Doing low 600 rwhp is pretty common but high 600 rwhp is impossible except for the most radical setups ($$$$).

Depends if you're octane limited now or not.. if so, then yes you could pick up some power. If not, then no, probably not.
