I have read the articles on the "Traction Dyno" on Mr. Shope's earthlink.net website and am very interested in using one to adjust my car before it's first run at the track. However, I have a couple of questions to see if I understand the principles correctly. As I read the article I see that I will need to fashion some sort of anchor behind the car to be able to "load" the suspension. I was thinking that I will need to anchor the car to possibly a wall in the garage. Does this sound correct? As your article states I will only have to provide a few hundred pounds of force to get the readings and should be able to calculate the greater forces through some calculations since you said the readings are a linear pattern. One other thing I don't understand is how I will need to fashion something to keep the engine from trying to move. As for attaching the chain to the rear of the car I should be able to attach the chain to the parachute mount since it should be a the CG height. Thanks for your help in advance.
