Underdrive Crank Pulley Kit
Cargraphic Underdrive Crank Pulley Kit for the Porsche Cayman
The underdrive crank pulley kit is precision machined from 6061-T6 Aluminium on the latest CNC machines to ensure the balance and precision your Porsche requires. This kit utilizes a reduced diameter that was extensively tested to ensure the accessories (power steering and air conditioning) would not be reduced too far for street driving but to minimize the parasitic losses from these components and free up power.
Our pulley is also significantly lighter than the stock counterpart.
These combined benefits result in a net gain of 5-8 horsepower over stock figures.
This complete offset pulley kit includes all 5 components - Alternator, Crank, Power Steering, Tensioner & Water Pump
