    • 600+ whp B58's soon? BigBoost Stage 3 F22 M240i increases horsepower record to 571 whp

      The B58 is looking strong early on, isn't it? BigBoost is pushing the platform hard with their turbo upgrade offerings. Last month they set the horsepower record on the platform with a 534 rear wheel horsepower Dynojet pull and now they have increased that number to 571 whp.


      Keep in mind the tuning and turbo setup is a work in progress. This is not yet done but BigBoost is already pushing the B58 close to ~600 whp territory:

      The RPM signal was not reading correctly so we could not measure torque above 5000 RPMs. Any way maximum torque in this run was around 554 from the partial reading we had.
      As already stated more work and more dyno runs are to come but things look very optimistic for the B58.

        I hope they're not using a $#@! ton of meth as a bandaid for not enough fueling from factory. I'd rather go port injection than rely on a meth stream for the street at least - I know they (might not be the same firm) is developing the first PI kit for this motor.

        Hi Guys, yes this is stock internal engine.

        The turbo details can be found here: http://bigboostusa.com/product/master-power-mpr615/

        We are running 98 octane with e96 going through TBI injection for now. Our PI system is coming soon, we are just waiting for some of the first units to come out and try one on our car.

        We are trying to get a stock piston and rod to send in to Carrillo and CP for custom manufacturing of forged internals, maybe by the end of this year.

        Do you have a graph that shows RPM?

        I got this, Tony LOL.

        I'm trying to hold out for a flash (just like everyone else, the person i know who is working on it hasn't got it down yet). I may just get a JB+ to add a couple psi in the mean time.

        Curve isn't too bad either. Pretty broad power from 4500 on.
