What Is The Smallest Pulley I Can Run?

The smallest pulley that can physically fit onto the snout is a 19psi (2.55") pulley and only if the snout is machined. In order to run this pulley safely, your vehicle will require either one of our 'Intermediate W2A' or 'A2A' Intercooler kits and a custom tune. If you would like to spin the blower even faster, an overdriven balancer can be used. An untuned vehicle with no form of intercooling can run a maximum of 10psi (3.4" pulley).
