Active Autowerke Underdrive Pulley Kit (E9X M3) - 13-001
This is a complete bolt on kit engineered for BMW Performance tuning. Uses
aircraft grade billet 6061 Hard Coat Anodized Aluminum for the strength and
durability.
The BMW S65 V8 engine as used in the BMW E9X M3 does not make available all
of the horsepower that the engine actually produces. This Power Pulley KIT
through a redesign of the crankshaft outer pulley, actually releases this
developed and available horsepower.This performance product is designed to not only to make available
horsepower but to still retain all the inherent qualities of your BMW E9X
M3 without sacrificing reliability.Another key element in the launching of this under-drive 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 Autowerke philosophy 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 industry 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.Anodized in a hard finish as revealed by the almost jet black color also
makes this BMW performance product seem obscure within the engine bay. This
performance upgrade is easy to install and can be fully reversible if the
need arises. It is packaged to be simple with a crank pulley and correct
matching belts in a all inclusive KIT. 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 that wants to "... COME PLAY WITH POWER..."u00a0
