Lightweight Crank Pulley
Taken off of car after a month putting back to stock.
Text from Craven web site:
Your supercharged MINI has leeches! The Crank pulley that moves the belt, that spins the supercharger pulley, that puts the pressure on the engine, in order to get power out of a mini engine, is too heavy! This 7 lb weight that the engine has to spin every time you rev the engine is leeching power that could be much better spent on making the car get up and go. Craven Pulleys are severely lightened to severely cut rotating mass. Compare the 7lbs. weight of the Cooper S model crank pulley to a mere .875 lb. on the Craven lightened pulley.
Bigger IS Better (sometimes)
This pulley is 2% over sized to drive your supercharger faster by altering the ratio between the size of your supercharger pulley and that of the crank pulley. When combined with the uber-popular 15% reduction supercharger pulley a synergistic effect is achieved. The ratio is exaggerated such that much less energy is required to spin more revolutions. The result is increased pressure (psi)(boost) at the disposal of the supercharger. Experts have likened the results to using a much smaller supercharger pulley, like a 19% reduction. By increasing the size of the crank instead you can retain the stock sizing on your belt. Since we use out Tru-form profile on all of the pullies we manufacture your belts will last longer.
