Anyone fit a bigger supercharger on a 230k?
Even if installed pulley the size of a family pizza that tiny eaton is going to bottleneck the performance or explode.
Also shelling over a grand for maybe 30 more off the rears seems a bit much to me...
Soooo, has anyone replaced the whole unit?
My intention was a turbo-conversion but making that street legal in this sorry country is too complicated and expensive.
There is a loophole tho. Since it's supercharged, it doesn't matter how huge the blower is. Only limit is +20% from the most powerful model. Of any C-class that is... So I got some room to play.
So, what options do I have? I have access to a shop willing to make an adapter if needed.

The turbo conversion is not so easy because of the ECU (SIM4LKE) which use an electronic bypass valve to control the presure. Be aware that the OEM MAP sensor max out at 1,1Bar overboost and the maf sensor max out at 182g/sc.
From the other hand the M271 with can't make more power than 200RWHP (about 245HP at the crank). You can check at the link below how this can be happen.

If you want more power you have to swap bigger engine.

My friend Vmaxx, spining the sc faster with smaller sc pulley or bigger crank pulley, will not give any power. You have to change the valves on the ECU maps for A/F ratio, boost and MAF. If you didn'do so no matter the rpm that the sc is spining, the ECU will use the electronic by pass valve in order to keep the boost in the OEM values (0.68bar). The only way to be able to access this maps is the Damos files. keep in mind that M271 MAF max out at 182g/sec. For is the reason, Kleemann use the K-Box in order to clamp the signal for maf & map and with the 5bar fuel pressure regulator (OEM is 3.8) put more fuel in the engine with the same injector pulse. It is not correct and this is the reason why many cars with the boost kit on give CEL for lean mixture under havy load for some time.

MBWorld Fanatic!
Earlier M111's on SLK's came with M65's stock.
Check out Subby_ on benzworld.
He has his with over driver crank, underdriven SC snout, + ported supercharger.
And needless to say bigger fuel pump, and injectors.
It really screams!
