• Weistec Stage II 2.3 liter W204 C63 AMG M156 supercharger Dyno Results, gains of 122 wheel horsepower

      I finally took the C63 I modified for my friend to the dyno. As I posted before, it dynoed 450rwhp with an ECU tune + Supersprint headers. I added a 2.3L to it and the car just runs amazing. It beat a couple of modified 2013 Shelby Mustangs, some modified GTR's and a couple of ZL1's I took it to the dyno. It was crazy hot. Temps were around 110F. I was really surprised to how well and consistent the beast dynoed in this hot weather. All 5 runs were close (within 10 whp difference from min to max).

      The car does not have an Ice Tank, it did 572 whp, a gain of 122 whp from the previous dyno run on a hotter weather. Thank You @Weistec for calibrating this car with an amazing tune as promised.

      Here is the dynosheet:


      Here is a video:


      Here are the conditions of all the run, very undesirable conditions, but the engine was surprisingly consistent:



      Here is a comparison graph between the previous runs and runs after the supercharger upgrade, a healthy whp gain:

        Well done @Jacob502, promoted to the front page with some edits.

        122 more horsepower on top of a tuned C63 with headers with only the Stage II in hot weather on pump gas is impressive.

        He's not far from 600 whp.

        Thanks Joe

        It most certainly WILL hit 600rwhp by adding an Ice tank and adding race fuel to the tank.
