Hi all,
So I finally was able to test the stock water pump for flow a couple of weeks ago, using a cheap flow meter off the internet, shaving it down to fit in the top water hose, and utilizing my Fluke 115 multimeter on the Hertz scale. This is just for a point of reference for anyone interested in these details. I have attached a picture of the flow meter being tested, and a pdf of an Excel spreadsheet graphing the results. I think it was tougher getting the excel pdf down to the 48.8k file size than doing the test:fat:. Anyways, I did all this since I've upgraded the fan and the radiator but still not entirely happy with the idle temperature when there is no breeze.
The results were a surprise! The pump was much better than anticipated, flowing around 10 gpm at idle, and 20 gpm at 2000 rpm which, from my research, is a pretty healthy flow rate. So now I guess I'll focus on reinstalling baffles and testing the air temperature into the radiator with a new thermocouple I purchased for the multimeter.
