Audi 3.0T Gen 1 Supercharger 8 Rib Conversion Kit

Billet Aluminum Supercharger 8-Rib Conversion Kit for Audi 3.0T Gen 1 TFSI

Upgrade the factory 7-rib supercharger belt system on your Audi 3.0T with our precision-engineered 8-rib conversion kit.

Designed for Audi vehicles equipped with the Gen 1 EA837 3.0T TFSI supercharged V6 engine, this kit improves belt tracking, durability, and stability in high-performance pulley applications.

The kit includes:

• OEM tensioner mechanism

• CNC-machined billet aluminum 8-rib tensioner pulley

• GripTec 8-rib upper supercharger pulley

• Fluidampr 8-rib crankshaft overdrive ring

The GripTec upper pulley must be used with a compatible GripTec hub. The lower overdrive ring must be used with the Fluidampr Crankshaft Master Pulley, part number 651201C.

Depending on the selected pulley combination, installation may require grinding down an unused engine-block standoff to provide proper clearance. Refer to the product images for the affected area.

Why Upgrade?

Compared with the factory 7-rib system, the 8-rib conversion provides:

• Improved belt tracking

• Increased belt contact

• Reduced belt flex

• Greater durability

• Better support for high-performance pulley combinations

Installation Information

GripTec Upper Pulley

Installing the GripTec hub and upper pulley requires placing the vehicle into service position or removing the supercharger.

A Jaguar supercharger installation video from Velocity AP provides a similar general overview:

Tensioner and Overdrive Ring

The tensioner installs like the OEM assembly. Service position is recommended but not required.

The Fluidampr overdrive ring can be installed without placing the vehicle into service position and must be used with master pulley 651201C.

Supercharger RPM Disclaimer

Increasing supercharger speed adds stress to the supercharger, belt-drive system, and engine. Operating beyond the manufacturer’s rated limit may cause component damage or engine failure.

The Eaton TVS1320 supercharger has a stated maximum rated speed of 20,000 RPM.

Use the following calculation:

Lower pulley diameter ÷ upper pulley diameter × engine RPM = supercharger RPM

Example:

• 57 mm upper pulley

• 206 mm lower pulley

• 7,200 engine RPM

(206 ÷ 57) × 7,200 = approximately 26,020 supercharger RPM

This is approximately 6,020 RPM above the stated rating.

The purchaser and installer are responsible for selecting an appropriate pulley ratio and understanding the associated risks.

Vehicle Compatibility

Compatible with select 2009–2017 Audi and Volkswagen models equipped with the with the Gen 1 EA837 3.0T TFSI supercharged V6 engine, including the Audi S4, S5, A6, A7, A8, Q5, SQ5, Q7, and Volkswagen Touareg Hybrid.

Confirm the engine generation and engine code before ordering. Model year alone does not guarantee compatibility.
