M113K Fixed Supercharger Pulley
The DTK Fixed Supercharger Pulley keeps the blower engaged at all times, delivering instant throttle response and consistent power throughout the rev range.
By eliminating the factory clutch mechanism and reducing rotating mass, the supercharger spins more freely, making the car feel significantly more responsive and alive in everyday driving.
While cruising intake temperatures and fuel consumption may increase slightly, wide-open throttle temperatures and efficiency remain unchanged compared to a clutched pulley setup.
Available Sizes:
From stock diameter to aggressive 68 mm options.
⚠️ Proper cooling, ECU tuning, and a belt wrap kit are strongly recommended when selecting smaller pulley sizes.
