Subject: Re: Cooling issue and lean condition concerns by Qack on 2008/9/18 21:23:59 Attached is a graph of the data, with extrapolation below 2000 rpm and above 5000 rpm. The data from 2000 - 5000 is absolutely linear and extrapolates to zero -- indicating that there are no losses over that RPM range related to RPM. My guess is that the water pump does not lose efficiency above 5000 -- it would take a lot more than 7000 rpm for the thing to cavitate and lose efficiency, but don't have the characteristics available to determine that. By the way, the higher values are: RPM GPM 6000 - 88.8 7000 - 103.7 |
