Cost of superchargers question

can you be a bit more specific. id assume you are talking about a centrifugal and a twin screw. ???

The prices of all superchargers are all around the same. Centrifugal superchargers usually r cheaper then your twin screw blowers. Of course the most expensive one u can buy is from the manufacturer which is ford and it's basically a whipple supercharger. The cheapeest one is thr 525 kit and then the big dog is 625 but u can also buy a tuner kit that u can have someone else tune and that ones is a few hundred dollars cheaper.

It all depends on what u want. Centrifugal, roots style, twin screw. What r u looking for out of your car?

It depends on the kit for example the 524hp vs the 624hp FRPP kit are very minimal differences other then pulley and the tune that is why cost is difference is minimal.
