What is it anyway?
This torque tamer is there to limit the engine's rotation when power is applied. Most will have noticed that the 'k' series will rock forward and back as it revs. There is a beautiful poly bush solution that Clive has already fitted The polybushes are much stiffer than the original rubber. Clive mentioned a very slight increase in vibration at tickover.
This is an idea to replace the bush with a substance that is equally as durable as the poly bushes but not as stiff. It is probably allowing 50% less movement than the original. Plus hopefully not transfer any vibration from the engine to the body of the car.
