Default Re: Has anyone tried running E85 in the GT?

I wouldn't on a turbo for several reasons. Primary three:

1) The stoichiometric ratio for ethanol is different.

2) The energy content per gallon of ethanol is less than that of gas. You'll loose milage, and cause you to dig into the gas more to try to make up power.

3) Wreak havoc on the exhaust temperatures.


I have tried it on NA cars several times though with mixed results. If a car is designed for ethanol however, you can adjust almost any of the factors that make ethanol different ..... all except the milage loss. It's just inevitable that MPG will suffer. One of the many reasons diesel gets better milage .... because diesel gas has more BTU's per gallon than gasoline.
