Re: Thinking of building a engine dyno.

Tony the hardest part of building the eddy current dyno, is getting rid of the heat that is produced. If the engine puts out 180 kW, you have to get rid of 180 kWs of heat.
The water or "Froude brake" uses the water to dissipate the heat. The Eddy current has to be air cooled, so it can only be used for short runs.
