    The ski is running 19.5 psi. Custom tuned MACSBOOST ECU, MACSBOOST Pump Wedge, MACSBOOST Double Valve Spring Kit, MACSBOOST Custom 68mm turbo installation, straight exhaust, 710cc injectors, 255lph fuel pump. MONSTER MACSBOOST Intercooler, 7500+ rpm on pump gas! Methanol injection..

    19.5psi is on 93, E85 should give me some crazy numbers.

    So, was it dynoed at 300 Hp or what? That video of some guy and a passenger going moderately fast somehow doesn't prove to me that it's making 300...

    How will the E85 make more power, I thought it took more to make less?

    Can you run more boost safely with E85?

    Can you run more boost safely with E85? = Yup, that's the main reason.
