    Maxing out a Vortech V3si supercharger on an E60 M5 S85 V10 with 100% E85 at only 8 psi of boost - 704 rwhp

    The Vortech V3si is a popular supercharger because it's fairly compact, affordable, and it is utilizes a self-contained oiling system. However, although it can make a lot of power as you see here on this E60 M5 it can also be maxed out fairly quickly as well.

    On 100% E85 and 8 psi of boost the S85 V10 is taking all the V3si can give it. The result is an impressive 703.8 horsepower and 491.7 lb-ft of torque at the wheels but we know the S85 V10 can make much more power with a bigger blower.

    As a matter of fact, over two years ago a Vortech T-Trim blower put down 774 rear wheel horsepower on an S85 V10 and this has yet to be topped to BimmerBoost's knowledge.

    Gintani plans on switching this V3si car to a T-Trim but we already know what it will do. Although with 100% E85 maybe topping 800 rwhp will be possible? It's nice to see Gintani finally utilizing ethanol over C16.

    Yes, pretty rare. I assume the same mods they do for S65 fuel systems which is larger injectors and upgraded pumps.

    Genuinely curious - is there a technical reason they shy away from running w/ the E85? I am guessing C16 has more power density, but E85 is a damn good fuel for boosted engines.

    Cleaner burn perhaps?

    Fuel system requirements and little experience with it I guess. I told them I wanted to run E85. They filled my car up with C16.

    I'm never running leaded anything ever again. I had issues with C16. Not worth it.

    Destroying 02 sensors, spark plugs, clogging injectors, etc.

    Besides fuel pump and larger injectors, what about fuel tank and fuel lines?

    Definitely the lines. I don't know if the tank is an issue?
