Alta V2 Supercharger Pulley: 15% or 17%

Details

While MINI may have given generation 1 Cooper "S" owners a literal boost over standard Coopers there is no reason to be comfortable with 163HP. One of the best ways to turn up the power is to turn up the boost with a smaller supercharger pulley. The ALTA Performance 15% or 17% reduction supercharger pulleys do just that. With the simple installation of this pulley and no other modifications will raise boost 3-5 psi, and more than 20WHP. With a 15% pulley this rise in boost pressure will increase 15 to 20 horse power. No other modifications to ECU etc., required. Customers with other existing modifications or those seeking more HP the results can be even better with the addition of a header, intake, intercooler and exhaust. ALTA Performance was the first manufacturer to design a two piece , taper fit Mini Cooper Supercharger Pulley. Today, it is the most imitated design on the market, in fact there are about 10 or so knockoffs on the market currently. Now they've upped the ante with the ALTA Performance™ Version 2.0 Supercharger Pulley. The new pulley features a stainless steel supercharger shaft coupler with installation site aperture and the first to offer direct torque technology. Ultra light aluminum body decreases rotational inertia and overall weight. Over sized belt retainers and belt groove teeth increase belt grip. A decorative end cap faceplate provides a clean sleek look.
