The prototype is on an engine that hasn't been run yet, I believe, and it might never run if the owner keeps tinkering with it. As soon as I can get myself healed up enough to get back to my machine shop, I plan to build another one and dyno test it. Right now, I'm not allowed to spend more than 20 minutes at a time with my foot hanging down below heart-level to avoid swelling, and I won't be walking on it for another couple of months! Frustrating!
