Ray Munday's plot is a calculation plot, not dyno data. With that said, it's not too bad from a relative perspective. It definitely shows the relation between your piston options and viscosity and how they can affect low speed or impact damping. I think it would be better if Ray speaks for his plot himself, but I think it is a well designed plot. Maybe he'd like to recreate that plot with actual data at some point?? :-) As with any calculations, many assumptions and simplifications usually need to be made, but it doesn't mean they are wrong. As I like to say, a model or test should only be as complex as it needs to be to give you the information you need in order for you to make the "correct" decision.

I have just made an impact tester, so I'm starting to get some higher velocity data. I'll say it doesn't look quite like I was expecting, but I think it can be justified. I need to review it more before I publish it. There is a lot of interesting little details that can be seen in the plots that a more experienced eye than mine can see (thanks ray). I'm still learning, but I hope to pass along those details as well. I think a lot of folks will be interested in what goes on inside their shocks, there seems to be a lot more than what initially meets the eye.

My next major publication will be a piston hole and number study at all three velocity levels. It will definitely take me a few weeks to gather, analyze and report that data, but it will be coming. I'm just as excited to see this data as you all are.
