    • BMW F87 M2 N55 tops 400 whp on pump gas with bolt ons consisting of RK Tunes tuning, Fabspeed exhaust, and Active Autowerke intercooler

      The main thing the N55B30T0 motor is lacking in the BMW F87 M2 is top end punch. BMW neutered the motor on purpose to prevent it from stepping on the S55's toes only to put an S55 into the chassis later themselves. Call it a cash grab if you want.


      If you have an F87 M2 there is no need to fret as you can get plenty out of the powerplant. Just look at this bolt on tuned example.

      Mods:

      RK Tunes dyno tune
      Fabspeed downpipe
      Active Autowerke intercooler
      Upgraded charge pipe
      Fabspeed rear section


      There is plenty of torque down low with 437 lb-ft at the wheels at 4000 rpm. RK Tunes manages to get 407 rear wheel horsepower out of it and a much stronger top end on 93 octane pump fuel.

      If the owner wants more than this, he will need to go to a bigger turbo that can really move some air up top.

        Nice to see pump numbers. Looks solid, but I am guessing no catalyst down pipe?

        Jordan didn't want to say other than this was a mild tune.
