What does a smaller supercharger pulley do? Smaller SC pulleys spin the blower faster for more boost; this enables the engine to make more power (in the form of low-end torque). Be careful, though. If you go too small right away, the engine will knock, which will rob power and can even do harm to your pistons under certain conditions.

How to measure the size of a supercharger pulley?
- CR = half the larger pulley circumference = π2⋅2R π 2 ⋅ 2 R , where 2R = larger pulley diameter.
- Cr = half the smaller pulley circumference = π2⋅2r π 2 ⋅ 2 r , where 2r = larger pulley diameter.
- Belt Length = (CR+2u C R + 2 u ) + (Cr−2v C r - 2 v ) + 2b.
What is better a supercharger or a ProCharger?
The procharger does not burn through fuel like superchargers do, and keep gas costs to a gentle rise. Prochargers also do not take power beyond legal limits as superchargers can do, so if you live in a state where extra horsepower is frowned at or even fined, a procharger may be a better option for you.
Is a ProCharger and a supercharger the same thing?
Prochargers are not a smaller supercharger they are just a centrifugal supercharger, they come in many dimensions from small to large you have to size them to your application (smallest being C-1 biggest being F4). Volute (pretty much the body of the supercharger) diameters range from 7" to 16".
How do you replace Buick supercharger pulley?

What does upgrading a supercharger pulley do?
APR's Supercharger Crank Pulley Upgrade increases the diameter of the factory pulley from ~162mm to ~187mm, which in turn spins the supercharger ~15.4% faster. This results in a larger bump in horsepower and torque across the entire RPM range, as the supercharger is spinning at an even higher rate of speed.
How much horsepower does a supercharger pulley add?
How much horsepower will a supercharger add? Connecting your supercharger to the engine intake can add around 50-100 horsepower.
What does a supercharger pulley do?
A supercharger is nothing more than an air compressor mounted on top of a vehicle's engine. A supercharger pulley is a device used on a supercharger to drive the unit through use of the engine's accessory belt drive system.
How do I get more boost from my supercharger?
The amount of air pressure over normal atmospheric pressure a supercharger develops is called "boost." Spinning the same belt-driven blower faster at a given rpm generates more boost. This is accomplished by changing the ratio between the crank pulley and the drive pulley.

How much HP does a smaller pulley add Hellcat?
For those who aren't sure, an increase of boost pressure of 5psi is significant. Enough so that with a “conservative” engine tune, the HellRaiser pulley on a Hellcat engine yields around 780 horsepower at the wheels on 93-octane pump gas.
Can a supercharger damage an engine?
Superchargers use air to increase power, meaning that overboosting the supercharger will blow hot air into the engine and could cause damage.
Does a supercharger make your car louder?
These differ mainly in how they get the air they compress into the intake valve of the engine. Twin-screw superchargers cost the most, but they can also sound the loudest. They operate by sucking their air through a couple of gears (resembling worm gears) and then compressing the air inside a rotor housing.
What is a good compression ratio for a supercharger?
7.0:1 to 9.0:1 compression ratio. The optimum compression ratio is 8.0:1. Higher than 8.0:1 is not necessary or recommended. Fuel, ignition timing, and total boost could become critical factors.
