I'm not 100% sure, but I believe on american cars like the '03+ Cobra and the Lightning, don't they change the actual supercharger pulley itself?

By the way, Leading Edge looks a LOT like the logo for Edge Performance Products (who make a lot of Diesel chips/programmers/etc).

Increasing the crank pulley makes all other pulleys spin faster (overdrive) thus the supercharger spins faster and creates more boost at all engine RPM's. The other pulleys are reduced in size (underdrive) to make the belt fit. Envision your ten speed bike were the pedal is the crank pulley.

If you look at the stock crank pulley on your SRT you will see there is no room to increase the pulley size without reducing the neighboring pulley.

Reducing the other pulleys just allows the serpentine belt to fit. That's what I like about the ASP pulley, it looks (it is) stock and retains the stock belt so there is less possibilities of issues if and when I need to go in for warranty work.

The simple solution would be to reduce the SC pulley, but with the electric clutch it must be difficult or really expensive.
