O.K., at least I thought it was interesting

I was just cruising around car websites, and a click led me to an article about harmonic dampers. This was the part that I found interesting, because of the specific test. From the article:

Katech conducted a harmonic damper test for General Motors several years ago. The test involved the use of four different aftermarket dampers on a 427-cubic-inch small block. From 3,112 to approximately 6,500 rpm, all of the dampers limited crankshaft twist to no more than 0.6 degrees. Above 6,500 rpm, things got interesting. Crankshaft twist increased by a considerable margin with three of the dampers. At 7,893 rpm, one damper allowed a considerable 2.0 degrees of crank twist. The second had 1.7 degrees of twist, and the third had approximately 1.25 degrees of twist. The last damper—made by ATI—allowed just 0.28 degrees of crankshaft twist.

Good Link and good info.

We use and recommend ATI dampers. We personally think they are one of the best dampers on the market.
