I acquired a brand new Eaton Supercharger with the following on the sticker:

Lu Lader Mech
A 271 090 21 80
Eaton 307960

I was wondering which Mercedes models this belongs to and any specs on it such as for what displacement sizes it is appropriate for?

Also, I can't seem to find out which model eaton this is ...(m45, m62, m90, etc)

The part number indicates that it's for an M271 engine, the 1.8L in the 2003-up C-class. However, the supercharger in the M271 C230K is A271.140.07.87, suggesting yours might be from the Europe-only C200K or C180K.

Diesel Benz

Should be for an M-class.

thanks for the clarification!

Don't know where did I pick up this ML reference, but this should have been used on some US engines too, on a 271.948.

203.040 seems to have used it (don't know if this has been sold in the US though).
