soo guys, I'm gunna build a chassis dyno @ some time. so question, how do I calculate the proper roller mass or inertia or whatever you're supposed to use? is there a good calculator on it??? article? I'm sure someone who is smart knows. for future reference and over the winter i have some ideas that could improve power and rpm so id like a proper way to prove it vs (like someone on here) just saying "oh yeah it makes such and such power" without numbers to prove. there's a guy who sells the Arduino board and has videos how to set it up, so that's the electronic side, but I just need to know how to calculate the weight, inertia, or mass of the roller,
