The Canadian Auto Performance Crank Pulley for the Audi B8/B8.5 S4/S5 and C7/C7.5 A6/A7 is the upgrade your vehicle deserves and needs to maximize the power it makes while mitigating heat soak compared to bigger sizes. Engineered and tested to consistently make more power than its' counterparts in bigger sizes. When it comes to maximizing power safely through a crank pulley for the supercharged 3.0T, this crank pulley does so in a fashionable manner while reducing rotational mass and the parasitic loss caused by the OEM crank pulley.
BELT NOTE: The belt that comes with the crank pulley will only work with a smaller aftermarket supercharger pulley. This belt will not work with OEM supercharger pulley.
Although stock Audis with the 3.0T supercharged V6 have sufficient power with the stock crank pulley once upgraded to Stage 1 or Stage 2 Single pulley, to achieve the highest power levels and yield the best daily drivability, a crank pulley is a must.
Known for being able to double output in power (from stock applications of 333HP to modified applications of over 670HP), the Audi 3.0T supercharged V6 engine is truly a master piece. Its Achilles' heel is undoubtedly heat soak caused by high intake air temperatures resulting from crank pulley sizes that are far too big for the stock supercharger to be efficient. Cars with a crank pulley bigger than what we recommend quickly become slower than even stock cars without any modifications due to heat soak and could potentially suffer from fuelling issues.
Upgrading your stock crank pulley to the CAP CNC machined billet aluminum (6061-T6) pulley will prevent power loss. The crank pulley is significantly lighter than the OEM crank pulley because it maintains an efficient, lightweight design, better than other crank pulleys available on the market.

This crank pulley comes with a 1320 belt included in every package.

Crank pulley and blower pulley are great products from CAP. The only issue I had was with the 1320 belt—the squeaky sound was very annoying—so I ended up switching to a 1310 belt.
The 191 crank pulley by cap has been nothing but a great upgrade and has been problem free
Straight forward to install. Even has mark for the offset hole. 2k Miles so far on my DP setup and no issues or loosening of bolts.
Make sure you buy this with the CAP heat exchanger to save labor costs and to avoid paying twice for similar work. CAP performance parts are such high quality. I am so impressed and happy that I will be using their parts for more mods on my s5.
I replaced my CTS Crank pulley with this and boy is the weight differences a lot! One weighs a lot more in the hand than the other. The Can Auto performance crank pulley is far superior quality and I am manual on my B8.5 Audi S4, the downshifts feel much more smooth than before. Highly recommended. Shipping was fast too.
