Applications: 2001 - 2006 M3, S54 M Coupe/Roadster (E46, MZ3)
The TMS Racing Alternator Pulley (For VALEO alternators) is designed to unleash MAXIMUM Horsepower and reduce alternator wear. Our pulley has been track tested on our Grand Am Cup M3s and dyno-tested for reliability. This pulley is strictly for race/track cars only, due to the size of the alternator pulley the proper voltage cannot be maintained at low RPM. We suggest installing with TMS Racing E46 M3 racing power steering pulley, P/N: TEN 46 23 R03 but this is not required.
Parts list for pulley:
Alternator Pulley
10mm Bolt
10mm Flat Washer
10mm Wave Washer
When would it be a good time to perform this work on my car?
When replacing a drive belt.
Before a race weekend to help you get to the podium.
What main drive belt do I need to use with the TMS Racing Alternator Pulley?
If you have the standard pulley kit with the racing alternator pulley you will need a 6 groove, 1524mm long belt
If you have the full, TMS Racing pulley kit you will need a 6 groove, 1538mm long belt
(you must have one of these kits to use this alternator pulley)
