Integrated Engineering 3.0T TFSI 207MM Crank Pulley & Damper Upgrade Kit | Fits Audi B8/B8.5 S4, S5, Q5, SQ5 & C7 A6, A7
IE's 207mm overdrive crank pulley for the Audi supercharged 3.0 TFSI platform increases boost for "dual pulley" tune power levels without replacing the press-on supercharger pulley for an easier install. This complete one-piece billet design replaces the crank pulley and engine damper for total reliability.
FEATURES:
- 207mm "dual pulley ratio" crank pulley upgrade
- Replaces crank pulley and engine damper
- Increases supercharger RPM by 27.6% over stock
- Higher boost levels deliver up to 548HP with matching tune
- No need to press on an upper supercharger pulley
- Lightweight design for faster & easier engine revs
- USA in-house designed and manufactured
- CNC machined from 6061-T6 aluminum
- Black anodized finished for superior protection and looks
- Laser-etched logo and alignment marks for easy install
- Includes high-strength bolts and proper-sized SC belt
Requires stage 2 dual pulley ECU tune
ONE PULLEY - DUAL PULLEY POWER
This 207mm crank pulley delivers a supercharger ratio similar to a traditional dual pulley setup that uses a combined smaller 57.5mm supercharger pulley with a larger 188mm crank pulley. This pulley allows the use of a dual pulley ECU tune without the need to purchase multiple pulleys and press off/on a new supercharger pulley for a faster and easier installation process.
If you already have a smaller supercharger pulley installed, purchase the 188mm crank pulley part number IEBAVJ7 to go dual pulley.

CRANK PULLEY & DAMPER
This complete one-piece pulley replaces both the crank pulley and factory engine damper in one unit. Replacing the engine damper provides increased reliability and protection from a possible faulty stock engine damper that is known to separate, causing costly engine damage.
LIGHTWEIGHT DESIGN
Weighing in at only 2025 grams, IE engineers have produced a robust pulley while trimming as much fat as possible without risking the structural design. The aluminum construction is 49% lighter than the stock setup, reducing rotating mass, resulting in faster engine revs and less parasitic loss.
MADE IN THE USA
This one-piece design delivers significant power and is a vital link that holds your engine and supercharger together. Enjoy the peace of mind knowing your pulley is 100% in-house designed and CNC machined from top-of-the-line sourced aluminum alloy followed by an extensive quality-control process.
QUALITY FINISH
The 6061-T6 aluminum pulley is finished with an attractive black anodized finish. The anodizing process offers superior protection against corrosion while retaining the proper installation clearances. After applying the coating, the alignment marks, part number, and logo are laser etched to guarantee long life and a fantastic look.
