• New 63 AMG / M156 horsepower record hit by Weistec Engineering custom supercharger build - 789 wheel horsepower

      Congratulations to Weistec Engineering as well as BenzBoost member ecampbell who provided this dynograph of his custom Weistec Engineering built supercharged CLK63 AMG Black Series. The car put down a very impressive 789 wheel horsepower which exceeds any other dynograph we have seen for this motor by a considerable amount. The car has a larger lysholm supercharger and also includes the Weistec forged pistons and rods.

      The driveline is also strengthened with Weistec components including strengthened axles / carbon fiber driveshaft as well as 1000+ horsepower capable transmission components. We look forward to seeing what this car as well as its sister car belonging to BenzBoost member @JRCART will put down at the strip which we do not doubt will result in a new world record.

      Congratulations to all invovled!

      @ecampbell @Weistec

        Wow that's a impressive dyno curve. Hold the torque forever and then when whp peaks it holds it for close tp 1000Rpm. What a steam train and seams a lot of boost trickery going on in terms of it's management.

        Maybe, I haven't seen the graph. These cars are similar though.

        Wow. Hats off to the Weistec guys. That requires solid engineering…….and a ton of trail and error. Thats pushing the envelope. Love to see the real time on that 837.

        @SLS AMG
        Looks like your information is outdated along with just about everything else you post.

        Earl - congrats man. When do you plan on getting it to the track and putting down some hard numbers ?

        Serious numbers. You got a monsterous M156 beast right there. I smell 9 seconds from you pretty soon. Is the 837 RWHP achieved with using a race gas tune?

        Keith stated on MBW that the car made 837 by race fuel, so that's around 30 rwhp gain. Just amazing
