KoduKoer,

Stock SLK R170 2.3 kompressor pulley diameter: 93.5 mm. Crank pulley 185mm. There is a guy on benzworld who machined his SC pulley down to 88mm.

Porting thread on this supercharger is at https://www.benzworld.org/threads/an...thread.1631863. All it really does for a given PR
M is to decrease energy required to rotate the rotors, which leads to less he
at, which is great. Performance gains are due to less heat rise.

AFAIK, in the SLK the supercharger clutch enganges at 800RPM.

BTW, great job on your install! Did you balance the pulley assembly?
