    • How big is the difference between stock F80 M3 / F82 M4 BMW S55 turbochargers and upgraded units?

      This big. This F80 M3 camera car caught our attention when it took down a Ferrari 488 GTB. Yes, it's fast. It is running the Pure Turbos Stage 2 S55 turbocharger upgrade along with BMS JB4 and PTF Bootmod3 flash stack for tuning.


      Watching it beat up on a new turbo Ferrari was incredible but look at how big the difference is between the Pure Turbos F80 M3 and a bolt on F80 M3. Quite simply, night and day.

      For those wondering if they should upgrade their turbos this result should be enlightening.

        The power band is a lot wider than stock turbos tuned. Makes the car a lot faster!

        Is that on pump gas?

        I'd assume race.

        It's funny but the difference between a bolt on and stock car can be massive. So can the difference between a well tuned car and a poorly tuned one so this result doesn't surprise me at all.

        I do think though that the F8x make a huge gain from turbos vs the E9x cars. Probably due to the better flowing head and the fact that that engine evolved from the N54. I think I'd love to own one one day but by the time they are affordable for me hybrids (combined turbocharged and electric drive) will be blowing them out of the water.

        Actually, the S55 is much more like a closed deck N55.

        Hate to tell you, but in short run acceleration tests, battery electric cars have owned internal combustion engine cars for the last decade or so, at least for the first couple of runs.

        That is what I would say as well.

        It just revs higher and the head flows a bit better. Also, larger twins from the factory so in a higher state of tune to begin with as it goes in the M car.

        The Pure S2s on our M3 is the reason we decided not to sell the car after 3 years despite the high risk of crank hub spinning. The car drives as nicely as stock and flat out moves. Click here to enlarge
