I had my 2008 3.4 whippled car tuned to run E85. The dyno run here in Texas at 97 degrees showed a run on 93 octane of 697rwhp and on E85 732rwhp. Any one else running E85?
No. You need a lot more injector (E-85 has a lower stoich and you have to inject more fuel) and you need a return style fuel system for complete effectiveness.
