MACE SUPERCHARGER PULLEY TO SUIT HOLDEN CALAIS VS VT VX VY L67 SUPERCHARGED 3.8L V6

Our Mace L67 supercharger boost pulleys are available in a variety of sizes from 3.8" (stock) down to 2.42". These pulleys are capable of generating 6 to 20 PSI of boost, depending on your pulley ratio and engine setup.

CNC-machined from high grade alloy*, these one-piece units are finished in a semi-gloss clear powder coat for long lasting surface protection and a superior appearance. Through strenuous hours of CAD-modelling, these direct fit pulleys bolt straight up to our modular hub. This ensures a hassle free installation and quick change-over when trailing different sizes.
