Moroso water pump.......

When i first started having overheating problems, was when i ditch the fan, fan clutch, and fan, for one of these moroso belt driven electric water pumps (Moroso 63750)
I have keep it and just delt with it becouse of the .10 in et that it gave me.
I never diven on the street any more and so i have just put up with the short drive time and lots of cool down time.

long story short,....I was reading an artical about how chry waterpumps actuly quit pumping water around 4500 rpm and how to make then flow to 6000. He also talked about the ratio and those that turned over 6000 should us a differant ratio so that it didn't turn the water pump over 6000 rpm.

This got me thinking about my electric water pump drive........... they sell a larger pulley, that incresses the water pump speed, that I install long a go.

Why all this Bla Bla Bla?

Well i have a snap-on tool that you can tell the rpm of anything by simply installing a refective piece of tape and it will give the rpm.

So one reflective tape on the electric motor that drive the factory water pump thru a belt. and a 2nt on on the water pump.

Any guess as to just how FAST that water pump was turning............:shaking2:

Nope not even close!!!!!!

950 RPM! AND THAT WAS WITH A FULL CHARGED BATTERY!
No wonder it take me so long to cool down the eng. I have been blaming my issuse on the electric fans and it's that d a m pump!

O and by the way the electric motor only turn 1900 rpm

Here is a picture of it.
