Up Graded - Performance Damper when do you do that?

Go to PERA.org and look at their webinars. There are some good ones on crank balancing. In fact, there was one last week but I missed it. I need to watch it.

At least one of them has some incredible CFD images of what a crank goes through. It’s eye opening.

IMO, once you change anything in the system like the crank, the rods, the pistons or RPM, anything like that you need a damper change.

Elastomer dampers have a very narrow effective range. Once you change something that changes the frequency of the crank, the OE damper becomes less effective.

Do guys get away with using OE dampers? Yes. Does that mean that’s it’s the thing to do? Not at all.

For anyone turning under about 8500 RPM I use a Fluidamper or the Innovators West damper.

They both have a much wider tuned range. They also don’t require different tuning when you change something.

Just remember, everything has a resonance frequency. Everything vibrates. When you change the mass you change that frequency.
