AA Power Pulley E90 M3
Single side belt for 2008 included. Add dual side belt for later models.
From AA Site:
This is a complete bolt on kit engineered using Aircraft Grade Billet 6061 Hard Coat Anodized Aluminum.
This performance product is designed to increase not only measurably horsepower but to retain all the inherent qualities of your BMW E9x M3 without sacrificing reliability.
Another key element in the launching of this underdrive pulley system was the task of manufacturing a DPK, a double side belt for the air conditioner. Whenever you alter the crankshaft main pulley size, it will also influence the size of the A/C belt. As of late production 2007, BMW change over the belt configuration to a double sided groove belt on the E9X M3. Active Auotwerke philisophy is always to try and maintain components like a BMW fashion, as if BMW would have done. This would be a first in the BMW performance industy to have an aftermarket DPK belt produced.
To further enhance the system, Active Autowerke will provide an extra spare DPK belt with the kit. This would be for emergency circumstances if the need ever arises.
Tested and ran on the in-house Mustang dyno here at Active Autowerke quantifies a true measurable 12 + horsepower gain on a completely stock BMW M3.
This performance upgrade is easy to install and can be fully reversible if the need arises. It is packaged to be simpe and all inclusive. Please verify your E9x M3 on the A/C belt if single sided or double sided (DPK) when ordering.
A must for the true BMW M enthusiast.
