Fluidampr Crank Pulley - Subaru EJ20/EJ25

SKU: fdr531101

$529.99 CAD
The Fluidampr viscous damper will reduce wear on your engines main bearings and timing gear. Therefore achieving more accurate valvetrain operation and lower the risk of crank failure.
 
Completely unlike the rubber based dampers, this will automatically adapt to your modifications. It will then continuously self-tune in real time, as the engine revs up, torsional vibration suspends the inertia ring and reduces its weight felt on the crankshaft. Measured as rotating weight, this effect helps maintain quick revs while preserving optimum dampening.
 
Benefits:
- Decreased engine vibration. No more flywheels, crank trigger wheels, or timing gears falling off of the crankshaft. This is unavoidable when revving past 8000rpm without an engine damper.
- 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. torque depending on your current setup.
- An overall more efficient and reliable engine.
