Magnuson S/C

This converts the stock press on design to a modular two piece design in which instead of pressing in a one piece pulley, first you press in a hub instead to the supercharger shaft, then you simply bolt up a pulley using 5 supplied Allen head bolts.

It makes for near on the fly pulley swaps and resolves the drama of pressing in new smaller or larger pulley's for good. All you do is buy a new one if you want to go down in pulley size diameter, remove the belt, unbolt pulley, install new pulley, reinstall belt, bank.

It's referred to as a Qwikchange Pulley kit. If you want to get one for yourself go to Pulleyboys.com then in the search box type in 5QCK and it will show you the one which works on our blowers.

Just be aware that any pulley smaller than 2.8 will require the snout to be machined.
