HOLDEN L67 V6 Boost Pulley Upgrade Kit - 6- 19psi

Holden supercharger 6psi - 19psi boost upgrade kits which comprises of a special modular hub, your choice of pulley, new belt and installation instructions. Also available is a pulley removal/installation tool for hire or outright purchase.

Also one of our key design features is that our pulleys support 8 rib belts, (which also works with the standard 6 rib belt) unlike the vast majority which only support the narrower 6 rib. Meaning that you have the option of easily upgrading to an 8 rib belt, to eliminate any slippage that may occur at very high boost levels (above 17psi).

Backed up by other tests, this mod is good for around 20 kw at the rear wheels for a car with similar mods as mentioned previously. Greater power gains can be achieved if further mods are undertaken such as an intercooler, larger cam, etc...
