Came across a site offering an engine damper which apparently will add gains of 3-10whp and 5-13ft/lbs. of torque depending on your current setup.
The USP Motorsports engine damper carries the following benefits:
-Decreased engine vibration. No more flywheels, crank trigger wheels, or timing gears falling off of the crankshaft. This was unavoidable when revving past 8000rpm in the past.
-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 efficent and relieable engine.

Any one care to elaborate or want to give it a go?
