    • Renntech M157 turbo upgrade on a CL63 Performance Package hits 691 horsepower at the wheels on pump gas

      And the turbo upgrade M157 dyno numbers just keep on coming in. So far we have seen race gas numbers from Weistec as well as AMS Performance and both have shown massive power at the wheels. Here are the Dynojet dyno numbers from Renntech who dyno'd their car on 93 octane pump gas. The result? In STD correct with the upgraded turbochargers on a CL63 AMG with the Performance Package Renntech hit 691 wheel horsepower.

      Impressive? You bet, especially when the torque figure crossing 800 wheel is considered. Three total dynographs were generously provided by Renntech one in STD correction, one in SAE correction, and one that is uncorrected.

      Further modifications to the car beyond the turbochargers are Renntech filters, the Renntech M157 intercooler system, transmission modifications, upgraded axles, and a limited slip differential. Great work as always, graphs below.

        The boost max. peak it's set to be under 1.35-1.4 bar dependent on ROZ position & gear. Garrett prototype CHRA & housings for the GTX 28/29/30's family offers a few designs for R&D. We used the one that can offer the best throttle response, packing, thermal efficiency & long term reliability Click here to enlarge
