      Add another 1000+ horsepower S55 to the the list. This time it is a BMW F82 M4 built by Cedar Performance in Dallas running KRATORS KRAS55Bi turbochargers which at this point are provent as 1000+ whp capable on multiple S55's.


      1005 rear wheel horsepower and 853 lb-ft of rear wheel torque:


      For whatever reason the full mod list is not being shared but what we know is that this is a low compression built motor S55 by Carbahn Autowork. It has Fabspeed exhaust pieces and upgraded cooling from CSF.

      As more details come out this post will be updated.

        Ok this is the same car that previously hit 995 rwhp: https://www.bimmerboost.com/content....-turbochargers

        What changed since then:

        Same car, same mods besides upgrading to the EOS intake manifold and fuel injectors. The bigger fuel injectors were not needed but i used it as an excuse to buy another part
        So, just minor changes to clear 1000 rwhp.

        Keep in mind this is a lower compression S55 built by Carbahn Auto Works.

        You are correct. Also, i'm not running Maximum PSI's crank hub fix. I am only running their chargepipe and j pipe. CarBahn addresses the crank hub issue their own way.
