While doing the research for my next motor I came across what appears to be a "quiet controversy" in regards to dampers.
One school of thought says that for a drag racing motor you should never have a dmaper that contains moving internal parts, such as a heavy silicone fluid. The reasoning is that since the motor is moving through it's RPM range so rapidly, the "moving parts" never have a chance to get into harmonic synchronization with the vibrations that are transmitted through the crank's snout, and that they therefore never actually manage to do any damping.
The other school of thought says that regardless of the use the engine is put to, the RPMs are still going to be moving up and down and that a damper that has moving internal parts is going to be able to "synch" with the engine so rapidly that it wont matter anyway. Plus of course, there is the fact that even if this were to be an issue with a dedicated drag racing engine, it wouldn't apply to street/strip cars that are actually driven on the road.
I was wondering if anyone could shed some light on this sissue for me, specifically in regard to the effectiveness of a damper such as the Fluidamper, since that is exactly the sort of damper that I had thought for years was the best kind you can get.
