Here was one of the new ideas that we tried. We've had problems in the past trying to figure out if the water pump was working properly on the dyno. It isn't uncommon to hear about people smoking an engine on the dyno because the electic pump failed but they didn't know until too late. I think it has killed a couple of engines at the EngineMasters.

So we made up a sight window for the water line distribution block. Now we can look thru the cell window and see if the water is circulating.
