Description
Body Design
Constructed of light weight 6061T6 aluminum, the ALTA SC pulley body decreases rotational inertia of the supercharger adding response to your engine.
Holes are cross drilled through the pulley and over each groove, to increase belt grip and reduce belt slippage as your belt stretches. Also incorporated into the design are oversized belt retainers, which reduces belts from jumping off.
Shaft Coupler Design
The ALTA Performance Supercharger pulley features a stainless steel coupler which clamps onto the supercharger shaft rather then wedging in place like other aftermarket pulleys. ALTA was the first pulley to use this clamp-on method, and it has proven to grip the supercharger shaft better than other aftermarket pulleys and it will work for those who have had other pulleys slip and cause damage to the supercharger shaft. Our hub will attach to supercharger shafts that have been worn down as much as .020" and still work perfect!
Additionally the ALTA coupler features an open installation site aperture in end of our shaft coupler which allows you to visibly verify that the shaft collar is fully seated to the supercharger shaft.
Balanced
The black outer pulley is machined on a lathe from solid billet aluminum. Since this part is perfectly symmetrical it is naturally balanced in its self.
The non-symetrical hub adaptor must be balanced to offset the weight of the clamping bolts and slit. In the machine shop we balanced our prototype pulley to within .1 gram at 16000RPM (even better than stock). Data from that balancing was added to the model and applied to all production parts ensuring the entire part is balanced.
Pulley Size
ALTA Supercharger Pulleys are offered in two sizes: 15% and 17% reductions.
15% Reduction -
This reduction size is the market standard and produces smooth, safe power increases of around 20WHP.
17% Reduction -
For those seeking a bit more power, the 17% is the ideal choice! Builds boost at a lower RPM giving you even more power down low where you need it, combined with another 1.5psi of boost at redline, it gives you the extra HP to conquer even the toughest challenge!
Installation Tools
The ALTA Performance pulley puller is the perfect tool to reliably remove the factory supercharger pulley from your MINI Cooper S (tool does not work on JCW or GP pulleys).
You can purchase your own tool; perfect for club events or group installations.
