    Default E85?

    Has anybody switched over to corn gas yet and if so does it help with the going fast game?

    It will only make more power if you specifically build the motor for it. Simply converting an existing gasoline car (N/A) won't make diddly squat. If you are building a motor specifically for it, then you can jack up the compression to 13-1, and run a nasty cam effectively, which you cannot do with pump gas. Just think of it as 106 octane gas, that gets shitty mileage.

    I have an E85 tune that I have yet to test... I think I need more injector first.

    that's true, except for you can run more aggressive tuning on the same engine, with E85 vs 93 and probably make some more power.

    But I know where you're coming from. All the kids around town thinking their shit will run faster with race gas when it's a stock motor lol...

    High octane fuel is a supporting thing, not a power adder.

    I was told by a tuner in Indiana thats real big into E-85 that he can make a car gain almost 100 horse if it's boosted and intercooled on E-85 compared to a boosted and intercooled engine running on pump gas. So thats kinda my goal right now to get my to run on E-85

    For a power adder car E85 is amazing. More boost plus a cooler burn with zero detonation= great results.

    The OP was talking about his N/A car though. For N/A cars the difference is teensy, especially when the motor was built for pump gas.
