Default Re: How much pump is enough? How much is too much?

18 to 80w might not be far of the mark actually

I was thinking heatsink / liquid cool the motor so it can be overvolted.

Add a 3D impeller, overhung volute diffuser vanes maybe even a variable geometry setup, ported output area to ½ inch tubing and watch it go. Efficiency would make it in the range of a 80 watt water cooling setup with the current tech and there would probably be less heat dump (due to pumping) and certainly less noise/ vibration to boot.

CAUTION: this post is powered by beer (budvar) to be precise hence is as inaccurate as an alcoholics ramblings
