    • The BMW B58 engine tops 700 whp - BigBoost Stage 3 turbo upgraded F22 M240i dynos 711.2 rwhp

      Is anyone really still worried about B58 tuning potential? The engine is hitting milestone after milestone in the aftermarket in quick succession. The latest barrier broken by a tuned B58 was the 700 rear wheel horsepower mark.



      On a Dynojet of course but the correction factor is not stated:


      A nice full, clean graph with RPM from Turbotek Racing would be nice but this is all we have to work with.

      This was achieved on MS109 fuel with BigBoost B58 charp pipe injection. The HPFP and LPFP are stock.

      The car is putting down some quick sprints with 100-200 kph testing in 5.41 seconds:


      Obviously this bodes well for the new MKV (A90) Supra and the S58 will have little trouble eclipsing the 700 mark as well.

        This is graph, will wait for RPM in the x axis!

        It's going to be crazy when all the Japanese fans hop on board because the JDM crowd seems to spend 10fold more on mods than the BMW community. It'll really give the BMW tuners some extra cash to make even more insane stuff.

        I wonder how stock fuel system keeps the pressure sufficiently high?
