Looking for Performance Underdrive Pulleys

mpiligrim · 08-19-2013, 08:32 AM

Well, that's pretty much it, anyone has seen those for 1M/335/135 N54? As long as my car is used as a a track tool only, currently I'm replacing second belt by now probably because of the regimes that both generator and engine are in right now.
Found similar product for M3 e9x, M5 e60, M6 e63 (http://www.fmudistribution.com/macht...drive-pulleys/).
Any suggestions? thanks!

There was some posts about puleys the outcome is that this thing is your engine balance... And there is a reason why it is so heavy...

Well it doesn't necessarily have to be lightweight, but less load on the generator would to enough.

Less load would give weaker tensioner or smaller pulley. But smaller pulley would would turn belt even faster
