Any chance those pulleys can work their way onto a V12? The M120 is pretty much two M104's sharing a common crankshaft.

M120 crank pulley has different crank pulley design, however thats not a garauntee that it won't work. Only way to know for sure is to get some pics of the M120 pulley and get one on hand and compare to the M104 pulley. Anyone have an extra? thanks

Be careful with underdrive pulleys. If the manufacturer calculates the size wrong by even a slight margin, you will wind up with chronic dead battery problems that will leave you stranded everywhere all the time.

Its not an underdrive pulley, its a stock diameter lightweight. underdrive pulleys are for hondas.

Ys, that's my opinion of them as well. I was shocked to see anyone considering one for a mercedes. Glad to see that's not the case.

you have PM E55 benzo.

Light weight pulleys are a fantastic way to improve performance with ZERO negative side effects. Underdrive pulleys are not recommended on such a classy car although some people still put them on their cars (accessory underdrive kits). To each his own I guess.
