Supercharger upgrade for a C200

I own a merc c200, and I was thinking of upgrading to a bigger supercharger but i was told that fitting a bigger pulley onto the existing supercharger would do the job...any suggestions??

If I was you I would first change the exhaust system if you haven't done that yet.
I would be scared to do any mods on the mercs as they are german and any stuff up would cost me a fortune to fix . Lets see what Gagan has to say

Well I gathered some news and its not good...the pulley kit is expensive(about 1.5lacs)..and on its own it won't offer much, the upped boost pressure won't do much good by itself and a ecu chip or a standalone is neccessary...kleeman is offering the kit for 1200USD which includes a pulley, K box, water pump pulley, V-belt, and a cotton element air filter, damn these things are expensive..!

hahah welcome to the world of modification bhai
