GFB lightweight pulley kits are a must have for your engine, made from aircraft-grade 6061-T6 aluminium they offer faster acceleration through significant weight reduction on the crankshaft.
The GFB crank pulleys for SR20 engines are underdriven, meaning the accessories are driven slightly slower to reduce parasitic losses. improving your cars acceleration by reducing the rotational mass on the crankshaft as well as parasitic loads from the driven accessories. In a similar effect to a lighter flywheel, the engine will feel livelier and more willing to rev.
People are sometimes concerned about possible adverse effects of lightweight pulleys and underdriving, but rest assured Go Fast Bits have done their homework! The underdrive ratios have been optimised to ensure there are NO adverse effects on the performance of the accessories. Whilst it is true that some engine types do suffer harmonic issues from lightweight pulleys, The kits are thoroughly application tested and do NOT cause engine damage in the short or long term.
