Re: Prony Brake Ideas
In the late 50's our company got involved in building quarter midget engines and needed a dyno to develop them. There was nothing commercially available so we built one using a V12 Allison coolant pump for a brake. It was a total loss system with just a garden hose for water supply. We never did have an engine on it that got it hot. The engines we were working with made around 25 hp.
