Re: Anyone running a turned down stock pulley?
Just doing some nerd math here....
Looks like based on the above calculations you gain:
- 81.65 SC RPM for every one (1) millimeter you increase the size of the crank pulley.
- 172.16 SC RPM for every one (1) millimeter you decrease the size of the supercharger pulley
Just some random information that could help those guys thinking about turning down their sotck SC pullies to run stacked.
