 Griptec Pulley and Hub for ( SOS ) S2000 Scienece of Speed Supercharger



This is a direct replacement for your kit pulley. Once the hub is installed, changing pulleys is

much easier. By removing the 6 Allen bolts you can option other sizes.


With the supplied pulley and belt, slipage is a always been a problem once you increase the boost by running a smaller diamete pulley as you have less belt contact.


With countless runs on the dyno and witnessing how much belt tension is required to maintain boost to reline, we were blown away with this combo.


Be running less belt tension, there's less wear on the belt, supercharger, idler and tensioner pulley.
