Active Autowerke Power Pulley Kit

E9X M3 S65 V8

Come Play With Power

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.

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.


Key Features:

  • HP gains: 10 RWHP ~ 12+ HP
  • Complete Bolt on System and is easily reversible
  • Aircraft Grade Billet 6061 Hard Coat Anodized Aluminum
  • Retains Factory Crank Hex Drive Adapter
  • Includes Replacement DRIVE and A/C Belts and EXTRA spare DPK belt provided where applicable
  • Designed for use on DCT and Manual models
  • Does Not Modify Factory Harmonics or Dampening
  • Reduces Rotational Mass
  • Does not cause overheating found in smaller pulley designs
  • Pair with the Active Software for Additional Gains


How to tell if you have a DPK or SINGLE sided belt on your V8 powered M3:

  • Take a look at the water pump belt, you will see that the belt is smooth on one side and has multiple grooves on the flip side. This is referred to as a SINGLE side belt.
  • Take a look at the A/C belt, if the belt looks, feels similar to that of the SINGLE sided belt that drives the water pump. We designate this as a 2007 ONLY model or models produced up 05/2008 which carries a single sided PK belt.
  • Take a look at the A/C belt, if the belt has multiple grooves on either side, then you have a DPK belt. Which is a belt with double PK grooves on both sides. Production model should fall from 6/2008 and up.

Best phone holder I have ever purchased!
Color: Dark Black, Size: 1 Pack
Hands down the best phone holder I have ever purchased. The ones that stick to the windshield always end up coming loose. This attached to your vent and is super sturdy. Very easy to install and uninstall without making a mess on your window.

Well worth it. Great product.
Size: 1 Kit, Size: 1 Kit
For the inexpensive price it’s worth its weight in gold. I admittedly probably didn’t work on it as long or as hard as I should have, but I still had great results. *** One warning: when it says to “tape up and cover your paint around it” do it! I figured I would just be careful but no I was wrong. It will REALLY damage your paint, so make sure you don’t get any on it. YES- This is the sanding discs too! They have chemicals on them, they are not regular discs. If you do get on paint, clean immediately! My only regret with this project and my fault, not theirs. My headlights went from dingy yellow, to much brighter and definitely more clear. Love the results. Very happy with the purchase.

Great for the price
Size: 1 Kit, Size: 1 Kit
Worked great at clearing my headlights and at a great price, I had used a different headlight kit maybe 5-6 months before and it did not perform as good as this kit did, maybe it was a user error with the previous kit but this one cleared it easily and was very easy to do and had a nice clear shine.

I'm Not Disappointed ...
Size: 1 Kit, Size: 1 Kit
I knew going in that my expectations shouldn't be very high because my car is a first generation 2010 Kia Soul. So its old with 16 plus years of yellowing oxidation and some abrasion. I took a chance with doing this because of the reviews and pictures. To my surprise, it worked better than I anticipated and could hope for. My driver side(left) headlight was horrible but my passenger side(right) wasn't too shabby and didn't require as much care. This would have turned out better if I had power drill attachments of the same sanding grit to do this. My arm is going to be really sore come Sunday. 😆 It wasn't too hard to follow the instructions as they were very simple for the application process. I don't know about the 2 years for it lasting, but for now, its durable. Once I drive at night, I'll be able to But all in all, it worked for me and its better than before I tackled it. All in all it looks good, I feel like I'll have a better beam when night 🌙 driving.
