BMW E36 M52 323i/328i Underdrive Pulley Kit

BMW E36 M52 323i/328i Underdrive Pulley Kit

Our kits are designed and tested inhouse. We run these kits in all our own street and competition race cars. We have been runnings these kits for over 5 years without any component or ancillary failures.
Suits M52b25/b28 engines.
The kits are designed to recoup horsepower and torque which is robbed through parasitic loss.
Expect better throttle response and a quicker revving engine once installed.
Accessories are slowed down but are left functioning in their safe zone. This also prolongs accessory life as they are not spinning as fast.
A gain of 5-8kw atw and 9-11nm atw is to be expected after installation. Very noticeable difference in these engines.
Included in the kit:
-Power steering pulley
-Water pump pulley
-Alternator pulley (please specify which alternator you have, Bosch or Valeo)
-Gates 6 rib correct length belt

Plug and play kits. No tuning required. No special tools required.

Made from CNC T-6061 alluminium, hard anodised black.
