I recently just bought my dream mustang, a 04 blue cobra convertible. In the next several months or so, I plan on buying myself a Kenne Bell Mammoth 2.8H, and also adding an exhaust system, headers, and an aeromotive fuel rail system. My question is which gas would be good for my cobra. My goal with my mods and upgrading the supercharger is around 800 horses. Should I run a higher octane than 93 for my car or should I switch to E85 Ethanol.

Thanks

If you go the e85 route be prepared to make one hell of a fuel system. E85 will max out your fuel system before something like 93+. Someone correct me if I'm wrong, but you will need to build for something that is 40% more with E85 than with pump gas.

Yes it's 30-40% more for e85. So your talkin bigger than normal injectors and a massive pump/return system. Plus, if your running 800 horses you can forget 93, you're gonna need race fuel probably all the time unless you defund it for the street.

From my research, the switch is E85 is definitely worth it. Check out SVTP or modularfords, a bunch of guys over there run it.
