Another Small Block Crank Damper question

A little more research should be in order.

The elastomer begins to wear IMMEDIATELY. And when it does, it starts to loose its ability to reduce harmonic vibrations.

This is a simple fact. Even ATI, the most beloved of dampers requires relatively frequent rebuilds to maintain any ability to function correctly.

You can use any metric to say these damper work, but they have a very narrow range of frequency in which they work, and a relatively narrow RPM range as well.

It's funny that Chrylser did a ton of research on this issue and they said to use a Fluidamper. I haven't use an Innovators West damper yet, but my next build will probably get one.

You used to be able to send a damper back east somewhere and they would test it. Can't think of the place now, but I had customers send back dampers that had a couple of years on them that had little ability to dissipate crank harmonics left in them.

In the grand scheme of an engine build, a damper is a very small cost. I have seen enough broken parts, fractured blocks and cranks, and all other maladies that come with uncontrolled crankshaft harmonics that tell me elastomer dampers are a short term proposition. At best.

I doubt all the guys claiming to run these things mile after mile and year after year have their dampers tested to see if they still have reasonable function.

If they did, I suspect they would be shocked.
