Add to your arsenal of pullies. These pullies all come with a machined finish and are designed to be used with the W Body Store Modular Pulley System.
What size pulley can I run on my car? - This is a very difficult question to answer as it varies from car to car and modification to modification. We can give you some popular setups and what they will allow you to do but we strongly suggest scanning for knock both before and after installing your new pulley. Please keep in mind the formulas below are based on a Gen III supercharger (97' - 03').
- (3.5 - 3.4" pulley) - Cold Air intake, U bend/ downpipe replacement, DHP PCM, 180 degree thermostat, Autolite 104 plugs
- (3.3 - 3.2" Pulley) - All the above plus: Rockers or a mild cam, ported manifolds or headers
- (3.1 - 2.8" Pulley) - All the above plus: More aggresive cam or intercooler, ported & polished heads, more specific tune (PowrTuner)
- (2.7 - 2.6" Pulley) - All the above: More aggresive cam and intercooler.
Please note: Pullies under 2.8" require snout machining.
