Thanks for the input cudabob496.
You're welcome. In the summer, I was doing some street activities, running between stop lights about 1/2 mile apart. I was taking it up to
6000 rpm on a run, and if I got caught at a stop light, the electric could not handle the heat that had been generated from the run. It was about
90 out, and I even have an alum radiator. with an mechanical pump, you are getting much more than 45 gpm I think, because you got your engine at 6000 rpm.
Plus, you are dumping a lot of heat into those aluminum heads. In cooler weather, the electric did better. And one time, I blew a fuse for the electric pump, and I had instant steam blowing out of my radiator overflow bottle! Temp zoomed past 230. Immediately shut it off, but was in highway traffic, and barely made it to the side of the road!
After that, went back to mechanical. heck with saving 3 hp!!!!
