Fluidampr Street Series Engine Damper - DSM

Product Details

Fluidampr Engine Dampers are designed to control destructive vibrations which are transferred through the crankshaft.

Each time the air/fuel mixture inside a cylinder is ignited, the combustion that occurs creates a torque spike that is applied to the crankshaft through the piston and rod. This torque spike is so severe that it not only turns the crankshaft, it actually twists the crankshaft ahead of its normal rotation and then the crankshaft rebounds. This twisting action is known as torsional vibration. When these torque spikes and forces get into phase with the natural frequency, critical torsional harmonic vibrations occur and can be seriously destructive to the bearings and the crankshaft. Dampers are designed to control those destructive vibrations.

Critical harmonic vibrations occur numerous times in a engines operating range. Stock rubber and elastomer-type dampers are frequency sensitive tuned absorbers, and work at only one critical frequency. In the case of a stock rubber damper, it is tuned for a factory engines critical harmonic vibrations. If you change the mass of pistons, rods, or the crankshaft, you change the natural frequency of the crankshaft assembly; therefore, the stock damper is no longer tuned to the new frequency of vibration, and you may be headed for early failure of expensive engine components. Dampers also create heat while they work, and rubber is a poor dissipator of heat. This heat and the exposure to the elements deteriorates rubber, causing it to crack and change durometer, which then leads to inertia ring slippage, damper failure, uncontrolled torsional vibration, and costly engine parts breakage.

i also have a talon project car and recently purchased a t3/t4 turbo set up and it only took a week. these guys are great. just to tell you how cheap they are, the parts store around here whants 1000 dollars for a stock 14b turbo and i got the t3/t4 turbo, front mount intercooler, blow off valve, wastegate gaskets and hoses for only 665 dollars what a deal.
