Spools like a different car
Backpressure gone. Boost comes in a full 400rpm sooner and it pulls all the way to redline now. Fitment was dead-on — no massaging, no fighting the O2 bungs.

The details
Unlock massive power without the heavy, sluggish drawbacks of an oversized crank pulley. Our precision-engineered 77mm supercharger pulley is the ultimate bolt-on performance upgrade for your 55 Kompressor AMG. It delivers the exact same boost equivalent as a massive 180mm crank pulley, but with vastly superior efficiency. Expect safe, reliable, and track-tested gains of 70+ wheel horsepower (WHP) and a brutal surge in low-end torque.
This upgraded pulley is the absolute perfect addition to a set of MBH long tube headers, allowing your M113K V8 engine to breathe freely and maximize its true horsepower potential.
Traditional oversized crank pulleys add heavy, unnecessary bulk to your engine's rotating assembly. By upgrading the supercharger pulley instead, you get all the boost with none of the parasitic drag. Because the engine isn't fighting against its own rotational weight, it can spin up faster and deliver power more efficiently.
Massive Horsepower & Torque: Instant, safe gains of 70+ WHP that pin you to your seat.
Less Rotational Mass: Eliminates the heavy bulk of a 180mm crank pulley so your supercharged V8 operates with maximum efficiency.
Faster Engine Revs: Noticeably sharper throttle response and quicker acceleration as the engine snaps into the powerband.
Lower Engine Temperatures: Less strain on the crank assembly means better thermal management and cooler operating temps.
Optimized Efficiency: Enjoy improved gas mileage during normal cruising compared to cumbersome crank alternatives.
