2010-2014 SVT Raptor Whipple 2.9L Replacement Supercharger Pulleys SCP-63375

Huge Power Increases with a Simple Pulley Upgrade

Whipple's lineup of 2.9L Twin-Screw superchargers for the 2010 to 2014 SVT Raptors are already some of the most powerful pieces of equipment that you can put on your truck and can instantly transform it into a monstrous machine. However, there's plenty more that can be squeezed out of Whipple's W175AX supercharger kits with a quick swap over to a smaller supercharger pulley. Smaller pulleys increase your supercharger's boost pressure output by causing the blower's rotors to spin at a faster rate. The smaller the pulley, the greater the boost pressure, and the more power and torque your truck will throw down to the ground.

Easy Install as a Direct Bolt-On Replacement

Each pulley bolts right on to your 2.9L Whipple supercharger's snout right in place of the stock 3.500" pulley. Whipple's supercharger pulleys range in diameter from stock 3.500" down to 2.750", with a maximum boost level of 15psi. On average, swapping in a new pulley takes roughly a half-hour, depending on whether or not you need tuning. Below is a table of pulley sizes and their potential peak boost levels.

PULLEY SIZE	PEAK BOOST
3.500"	9psi
3.375"	10psi
3.250"	11psi
3.125"	12psi
3.000"	13psi
2.875"	14psi
2.750"	15psi

All boost levels are estimated, may vary from truck to truck, and are based on the stock crankshaft pulley size. Pulleys smaller than 3.250" in diameter will require a smaller supercharger belt for proper function. Smaller pulleys may require custom tuning depending on your truck's other modifications. Smaller pulleys are not recommended for trucks with stock internals. Larger pulleys with less boost pressure are also available.

For Whipple Superchargers Only: these supercharger pulleys will on fit Whipples W175AX 2.9L supercharger kit for the SVT Raptors, F150s, and F250s with a 6.2L V8.
