Re: Water Pump Flow Rate
Has anyone done experiments on the flow pattern (other than Ford) of the V8?
I believe the biggest draw back for these engines, is the fact that they run the exhaust system through the water passage and that heats the water and creates a flow blockage. I don't think pump volume is the issue.
I know that there was a recommended enlarging of the two center block holes, to 5/8 & 3/4" on early and flowing more water to the rear of the 48-53 engines but even the 48-53 engines over heat more than most OHV V8's and inline FH engines that don't run the exhaust threw the water system.
In the 80's, I use to make a SBC water pump that ran a 2 1/4" impeller at direct engine speed. I had a few engine builders that told me that they didn't think there was a water pump available, that moved the water slow enough to over heat a SBC. That was a 8000 rpm at full load. Much more heat (BTU) than a early V8 has to cool.
It seems to me, that experimenting in this area could bring benefits to all.
