The Fluidampr viscous
torsional damper is an essential component in building a high performance 2.2
We recommend you read our FAQ on Fluidampr technology to understand
why this product is right for you.
The last 2.2 20V TURBO to leave the assembly line in Germany was 1997. By now
your Original damper has hairline cracks in the rubber ring which is robbing
your engine of horsepower as it is no longer adequate enough to perform the job
it was designed to do coupled with the disheartening fact that Audi has
discontinued the OEM vibration damper leaving countless to scour the globe for
good used units. In the past we have modified a current Fluidampr offering to
fit the AAN but we present the worlds first viscous torsional damper for the
2.2 20 Valve turbo Audi inline-5 engine.
When starting this project, we sought the help of global legend Jeff Gerner
@ Four Ring’s Performance (fastest Audi in the
world) who oversaw the design aspect of the project to create a product that
will suite the needs of all Audi fans alike.

- Decreased Flywheel &
Gearbox clatter (Especially with the 01E gearbox) . Flywheel clatter can
be heard when converting from the OEM dual mass flywheel to a single mass
flywheel (whether steel or aluminum)

- Engine Vibration reduction .
Extremely critical with thrust washers and additional tone rings.
- Sized for an OEM replacement
at 162mm. Does not over drive or under drive the accessories.
- Centre hub is machined from
4340CrFe in order to withstand the 255Lb-Ft torque of a the OEM bolt.

(Hardware & Balancing): Install hardware per OEM
The AAN (and other older inline-5) engines are balanced as a complete rotating
assembly. We do not recommend installing this product on a motor currently in a
vehicle. The rotating assembly must first be zero balanced and then the
Fluidampr can be installed.If you are going to remove any material from the fluidampr
, do so from the centre hub NOT the damper itself. Failure to follow
this instruction will result in potential catastrophic engine failure or at
minimum extreme cabin vibrations. Please seek the assistance
of Jeff Garner’s engine building services or
your local machinist before purchasing.
