    • N55 takes down S55? MHD Stage 2 tuned F22 M235i vs. stock F82 M4 DCT highway pull

      The N55 gets laughed at on the BimmerBoost BMW Performance forums because it tends to be the weakest factory turbocharged BMW I6 motor. The stock torque curve is ugly and the N54 gets most of the attention not only due to being on the market longer but stronger factory turbo results.


      A tuned N55 certainly wakes up quite a bit and if you need proof look at the video below. This M235i has the following:

      MHD Stage 2+ 93/98 N55 EWG OTS tune
      Upgraded Intercooler

      That is enough for it to impressively pull on this stock M4. It is almost hard to believe a factory turbo N55 could pull this off.

        It doesnít look like the video embedded, but thatís a pretty strong N55. Itís a shame the N55 hasnít proven to be a more capable performer than the N54, but at least they seem to be less problematic in regards to fuel pumps, injectors, ignition coils, and general mis-fires.

        Which intercooler and "high flow" down pipe? Straight pump fuel with no ethanol?

        I replicated this on my iPad. Sorry, working to resolve.

        Any FBO/N55-EWG will beat a Stock M3/M4 Base but put it next to Comp Pkg and the story will change.
        I ran the fastest FBO 435 RWD 6MT (who beats on 8AT EWG lol) car in North East in my 17' M3 Comp Pkg DCT and it was no match by 80mph.
