GripTec Pulley

GripTec Pulley
GripTec pullies are the premium upgrade for any supercharger build. Belt slip is a very common issue on supercharged components. In fact some units cranking out as much as 14-16 psi can take up to 200hp to drive. Often the drive systems are plagued with slippage issues and builders find themselves moving to noisy cog systems, where belts have shorter life spans, are difficult to find at just any parts store and they can create more heat through the frictional movement of the cogs. Belt slip isn't always noticeable. Often belt slip is noticed when the system squeals, squeaks or boost falls off. Did you know that naturally the belt can slip a very small percentage even on NA vehicles, one major factor to belts wearing. Belt wrap does play a key factor in minimizing belt movement but when it comes to driving a supercharger is hard to fully eliminate with just surface contact. Systems running 3.4 upper pulleys can see as much as a 1.5 psi gain when matching size for size pulleys.
