On our new 540 blown alchohol caddy motor (that wasn't ready for speedweek )the enderle injector pump is mounted on the timing cover where the water pump would go, I would like to remote mount an electric coolant pump.
So which coolant pumps are folks using on their race cars?
How much hp ya gona make 650, 750, more? Then ask any of the electric pump builders how much PRESSURE not flow they have. After that take your fuel pump off the front of your engine and drive it with a belt along with a water pump that will do the same. Yes you can run a high flow electric pump but if you do it on the dyno and you have a sight tube in the return line you might "SEE" what i mean.
I think you hit on our new problem with Hooley's Stude. We video the gauges and last year the water temp was just getting to 212 at the end of the 5th mile. This year with 14-15 lbs boost vs. 8 lbs last year the water temp was going from 212 to to 250 in the last mile. As soon as he shut the motor off with the elect. pump ( a Meziere) still running the water temp went down to 180. We run about an 18 gallon water tank. Since it went down to 180 I know we hadn't heated all the water up to 250.
So do we, not have enough flow, enough pressure, steam pockets stopping water flow???
The temp gauge sensor is in the return off the front of the motor by the neck where we fill the water and we use a washer like restrictor in the thermostat housing. If the water didn't circulate then I would think the sensor would not of had water around it and would have shown cold.
We run the elect. pump due to the blower drive and the mech. fuel injection pump on the front of the engine.
So now I guess we are searching for answers to get the water we have through the engine. We also plan on upping the water tank to 30 gallons or so, but that isn't going to help unless we can move the water through the engine better.
Any ideas, suggestions??
