Hi.

Steve I think off the top of my head the boost pressure on the Eaton M45 Supercharger is in the region of 8-10 PSI thats over and above atmospheric as for the drive pulley diameter I don't know. There are several "tuning" companies on the other side of the atlantic who sell smaller pulleys to up the rpm off the supercharger but have read mixed reports about them, I would think if you're going to up the boost you'd probably have to remap the fuel injection to keep up:?

Is it def the Eaton M45 fitted in the C180 kompressor? I have been unable to find that out with online searches!!

To the best of my knowledge the Eaton 45 is the only S/C Mercs used on the 4 cyinder engines

I've just traced this diagram of the C180K http://www.detali.ru/cat/oem_mb2.as...605716.628&CT=M&cat=63A&SID=09&SGR=100&SGN=02 and to be honest it looks different to the layout on my C230k although it still looks like an
M45 but different layout and drive pully. Heres the setup on my C230k http://www.detali.ru/cat/oem_mb2.as...GM=717.460&CT=M&cat=19K&SID=09&SGR=100&SGN=02 see what you think. Hopefully Malcolm will come back with something more diffinitive.

Looks like the SC has a different casing???

Still need to know the size of a standard bottom pulley if anyone can help???
