A turning point in Mercedes tuning...Performance Supercharger Pulley
So, IMO the C3 is worth it for the price and easy install. I had the 2nd generation pulley and had no issues at all while it was on my car. But I think the 185 pulley is definitely the way to go if you want the most power out of your car for just a few more hundred bucks. Cant go wrong either way
A word of caution however, C3P is not an easy company to get in touch with. You might search the forums before making any purchases.


Day before installing intake pulley and belt wrap car made 310WHP after installing the stuff next day hit the dyno again, made 339WHP !!!! wow, not to mention the difference in throttle response and i feel the biggest difference is low down power, do not even need kickdown anymore for over-taking highway driving... Its fantastic, i love it!!! Hell it must be fantastic the 185 pulley setup, but i am worried about pushing more in terms of reliability... I have one of those g-tech meters in my car, I know they are a bit gimmicky, but at least even that shows an improvement even if the numbers are not true, its all relative anyway..
Good luck with your decision.

The Best of Mercedes & AMG
