This was done from home. I couldn't afford my own bench so I built my own. I built it with the ability to do both wet and dry flow testing into the bench. The wet stuff is new to me. I am working on getting more power for the bench. Waiting on my pitot tube. Fluorecent dyes and dykem. Plus other stuff before resuming on r&d on intake and exhaust tracks. It's been many years since I been able to do some r&d. Chris
