Bundled together to save you money and make a dramatic improvement with engine performance on your R53 SuperCharged MINI!

ALTA 15% or 17% Supercharger Pulley

The ALTA supercharger pulley will increase your MINI's horse power by 20WHP. No additional modifications to the engine or ECU are required.

The ALTA supercharger pulley features a stainless steel supercharger shaft coupler with installation site aperture and direct torque technology. The ultra light aluminum body decreases rotational inertia and overall weight. Oversized belt retainers and grooved teeth increase belt grip. A decorative end cap faceplate provides a clean sleek look.

ALTA Tensioner Stop

Why do you need an ALTA Tensioner Stop? SImple! At some point in your MINI's life, the serpentine belt that drives the Supercharger and AC, will fail. When it fails, the OEM belt tensioner mechanism plunges into the crank pulley, destroying the tensioner and crank pulley. The ALTA Tensioner Stop simply hooks around both ends of Tensioner dampener and limits the travel of the tensioner arm preventing damage when the belt fails. This simple and inexpensive part, saves you hundreds of dollars in repairs!
