I've got a 2000 c230 kompressor, is there any thing I can do to the supercharger to boost it output ?

 

The only thing I can recommend from talking with others is to contact someone like Speedtuning USA and doing both the Kompressor Pulley/ECU upgrade. It should give you around 235HP and some additional Torque. It is about $1,000 for the parts, plus labor/shipping.

 

are there any pullies that can swap onto the s/c so you can run higher psi?

 

You have to have the ECU programmed in order for a pulley upgrade to work. Many places that do ECU programming offer pulley upgrades.

Kleemann, Renntech, SpeedtuningUSA, Brabus, etc.
