562 horsepower to the wheels with the 82mm throttle body on 91 octane. Completely stock car other than the blower upgrade and associated tuning/parts. With the 74mm throttle body the car puts down 534 horsepower to the wheels showing that the throttle body upgrade is definitely worth it to eliminate a significant point of restriction.
The graphs Weistec is advertising their power gains with show 534 wheel horsepower with the 84mm throttle body and 512 wheel horsepower with the 74mm. They have hit up to 562 but Weistec is advertising the more conservative numbers. Speak softly and carry a big stick so to speak. Better to over-deliver than under-deliver so keep this in mind when looking at the graphs that a more aggressive tune/setup will obviously net more power but they prefer to be conservative.
Baseline on the car was 398 horsepower to the wheels, 91 octane, completely stock in SAE correction on a dynojet. With an 82mm throttle body, the Weistec supercharger upgrade kit, and a full exhaust, cracking the 600 wheel horsepower mark is certainly well within reason. Add some race gas and more boost... and well, this is quite simply one hell of an upgrade for 55 AMG's.
Thank you to Weistec for the graph and details. Also for providing the community with a solid supercharger upgrade at long last for the M113K.
