Crank Pulley, Audi I5 20v, Fluidampr, SFI Certified
SFI Certified crank pulley for Audi 5-cylinder motors, features a Fluidamper crank pulley that we have modified to fit this application. We've developed this specifically at the request of drag racers going faster than 10.99 who require SFI certifications on rotating assemblies.
Engine dampers are essential when building high horsepower and high revving motors. Up until now no one has made an effective damper for the VW/Audi platform.
The Fluidampr engine damper carries the following benefits:
- Decreased engine vibration. No more flywheels, crank trigger wheels, or timing gears falling off of the crankshaft.
- Decreased "Clutch/Gear Box Chatter" which is caused by lightweight single mass flywheels.
- Reduction in rpm drops when shifting in a competitive environment.
- Gains of 3-10whp and 5-13ft/lbs. of torque depending on your current setup.
- An overall more efficient and reliable engine.
This crank pulley is a direct fit to the end of the crank on all 10v and 20v crankshafts along with the OEM crank timing belt cog. The serpentine feature on the pulley is not designed for any one application however, it's very close to the AAN/ABY/ADU configuration but not an exact fit, some adjustments to belt accessories will be required.
This crank pulley is not a direct bolt on for any Audi applictions and is recommended for use in race cars that have had extensive modifications.
A little info about Fluidampr pulleys by Fluidampr:
Viscous dampers past present and future
The best dampers on the market are manufactured in the U.S.A. by Horschel Motorsports, an ISO 9001:2000 certified facility. Horschel Motorsports is continuing the tradition that started in 1946, when the first viscous damper was invented. Over 4 million viscous dampers have been made for heavy duty diesel, drag car, stock car, street machine, race boat and other high performance engines. Looking into the future, Horschel Motorsports promises to manufacture the best dampers available as well as engineering new solutions for developing engine technologies.
The fluid in a Fluidampr…
It has been rumored that the fluid in a Fluidampr turns to gel over time. Here’s a news flash, its gel when we pump it into the damper. That is how the technology works. The silicone gel inside the damper keeps the flywheel in place and functioning. So to put all of the competitions claims to rest, it is a gel, always and forever. Maybe we should have named them Geldamprs .
Let’s talk about rubber...
Other dampers on the market use rubber or “elastomer” as the insulator for the internal flywheel. Rubber deteriorates and wears down from repeated movements. In layman’s terms, the more you work it, the weaker it will get. The inertia ring that balances an elastomeric damper becomes unstable when the o-rings start to wear. Think of it this way, what does a car wheel feel like when it looses one of its balancing weights? How would a fan missing a blade function? A damper with worn o-rings can unbalance a crankshaft and destroy it.
The reason car manufactures install elastomer dampers at the factory is not for performance but for cost. The “rubber” dampers are cheaper and easier to make.
