R&D ΤΡΟΧΑΛΙΑ, OE SUPERCHARGER, 1.05 to 1, KAW ULTRA 250X

The R&D Racing Supercharger Pulley Wheel will deliver a noticeable and impressive boost in torque and overall horsepower. Designed and manufactured from high quality billet aluminum and precision hard anodized for superior belt wear resistance. The R&D Pulley is lb lighter than the O.E.M. steel pulley, and delivers 2.5 to 3.5 lbs of additional boost pressure along with 30 plus well fed ponies. The holeshot acceleration is a solid 1.5-2 boat lengths over stock with a top speed gain of 1 to 2 mph over stock. Impressive results! The R&D Pulley comes completely assembled with a new high performance bearing, all necessary hardware and installation instructions. R&D strongly recommends the use of the R&D Powershot Fuel Tuner and R&D High Output Fuel Injectors to increase fuel flow delivery when using the R&D Supercharger Wheel. Not using the recommended R&D Powershot and R&D High Output Fuel Injector Kit with the R&D Supercharger Wheel, can result in engine damage due to a lean air fuel ratio. 1.05 to 1 Ratio (entry level)
