This is a brand new high boost crank pulley for Jackson racing supercharger kits that are installed on a D16Y7/Y8 engine.

This pulley is only intended for 3-rib JRSC setups that already use the Jackson Racing crank pulley as it is offset to match the belt spacing of the D16Y7/Y8 kits.

The “stock” JR crank pulley is 6.2” diameter whereas this pulley is 6.725”. I would expect to see an additional 2-3lbs or boost.

This pulley has been discontinued for many years and few were sold because they were $300 and most people didn’t want to spend extra after dropping $2700 on a supercharger kit.

Asking $250 shipped which is less than they cost from Jackson Racing when they were still produced.
