    • BMW F80 M3 on the stock S55 turbos and fuel system with 100% E85 ethanol makes 577 horsepower to the wheels with custom PTF Bootmod3 tuning

      Great numbers here out of a bolt on F80 M3. What makes the result particularly impressive is that this BMW F80 M3 is on the factory S55 fuel system and the factory turbochargers of course.


      The tuning is a big factor and this is a custom E85 tune by someone called @carythelabelguy whomever he is. The tune is through the Pro Tuning Freaks Bootmod3 platform.

      Check out the Dynapack results:


      That AutoTalent Dynapack from the graphs BimmerBoost has viewed tends to read high compared to a Dynojet.

      Still, 577.7 wheel horsepower and 562.7 lb-ft of torque at the wheels is nothing to sneeze at. Excellent numbers and a stout M3 for bolt ons and an E85 tune.

        Just gotta love the power these cars put down with simple bolt ons. How bad is the Hub crank issue on the s55 motors? Do all years suffer from this or is in more prone To the 2015/6 years?

        BMW made some change but the crank hubs still spin so they never really addressed the root cause.

        Regardless, it seems the aftermarket solutions are holding.

        I don't think we've heard of (not to say every F8X owner is on a forum) a 2017 failing, correct me if i'm wrong. I beat the ever living $#@! out of my F80 Comp. pack everyday and its holding strong.

        Most tuners I talked to about this feel DCT's fail at a much higher rate...

        It doesn't help that 95% of S55 sold are DCT's though...
