hey ho!
ich bin mir 100%ig sicher, dass ein digitec mit 5-600 U/min besser geht, mac

Nochmals Mac,

Ab 7200 Drehzahlen mit einer 15% reduzierten Pulley überschrittet mann die von Eaton abgegebene Redline des Superchargers von 17.200 Drehzahlen. Das hierunten kommt von MCO:

The Eaton M45 supercharger has a specified redline of 17,200 RPM.
The stock pulley (2.06:1) MCS with a stock redline of 6950 spins the supercharger at 14,317 RPM. The 15% pulley (2.369:1) at stock redline spins the supercharger at 16,465 RPM. The 15% pulley with 7200 redline spins the supercharger at 17,057 RPM. The max engine RPM with the 15% pulley and keeping the supercharger below its' spec'd max is 7260 RPM. Anything higher and you risk damaging the supercharger.
If you have the stock pulley, you can spin the engine to 8349 RPM and not over-rev the supercharger, but I doubt the engine could handle that RPM!!!

I can't imagine that Hartge would put a 15% pulley and rev the engine that high, because doing so would over-rev the supercharger (obviously NOT good).
