I am thinking about buying a vortech sc trim supercharger that produces 5-6lbs of boost. My question is can I change the pulley setup to produce more boost and if I can what size pulleys should I go with. Car facts; DSS 308 with Holley Systemax Top end kit(heads, cam, intake.etc...) 255 fuel pump and I have a set of 42lb injectors, and a 4-bank SCT chip. Im looking for about 9-10lbs of boost. Any help would be greatly appreciated. Thanks
The base kits usually come with a 3.33 on the blower and a 6.87 pulley on the crank. You can change the blower pulley with a smaller pulley or the crank pulley with a large pulley and it will add more boost. They make 3.12, 3.00, 2.95, 2.75, etc blower pulleys and 7.25" and 8" crank pulleys to accomplish this.
Eric if I were to buy the kit and change out the pulleys do you have any idea on how much boost I would be a ble to run on that supercharger? Is the SC trim supercharger(5-6lbs) the same as the S-trim that runs 8-10lbs of boost just with a diferent pulley setup or are the 2 superchargers different all together? Thanks for any help.
