Nasir, knew a Pro Mechanic ran one. Eddy heads, solid cam, headers, 10 sec Duster. Check w/ the manufacturer, if they say it'll flow enough, with enough volume, then that would be a killer way to make "free" HP... I've thought about em....
You really want a "real" electric water pump if you are wanting electric. I ran that little external deal for 2 years and it consistently gave me issues. Would get hot and stop, or have a bad connection and stop, etc.
I now run the "real" moroso pump that replaces the whole pump with backing plate. 4 years. No issues. It is $ however
Yep I’ve read that, but was just curious if anyone had did it anyway. I know of one on a street car, but it’s only driven on short trips around town. I want to put some miles on my heap. The full moroso electric pump makes the most sense, but I would need to create a provision for the heater hose.
If your water pump pulley doesn’t have a fan bolted to it, you wouldn’t ever see the difference if you were running it by the crank or electrically. I’m not sure about the exact efficiency calculations, but eventually it comes to the power conserved for that becomes additional load on the alternator. The biggest advantage is that it keeps the impeller at a constant speed. Engine water pumps have a fairly narrow range of rpm variance as far as peak efficiency goes.
No reason to reinvent the wheel. They are designed (a old design I might ad) to run the pump to cool race engines between rounds and not ran constantly to cool a street engine.
