I was told that "they had done a few" and then they were supposed to look through their stuff and send me a pic. They called back to say they couldnt find a picture... but.. I am willing to give them first shot at my application.
 
IF it works, I'm sure others here will follow. If they screw me over, I will make sure everyone in my address book hears of it :)
 
I am working every day this week in ER, making $$$ so I can take off this weekend and all next week for Reno (air races) and Salt Lake City (BFR, Some velocity type training, and some Idaho Back Country in a 180), so I may not get to call them this week.

Subject: [FlyRotary] Optimal GPM water pump flow.

This may have inadequate variables, but looking for optimum Gallons Per 
Minute desired water pump flow for a 13B 2nd gen, at 6000 rpm but 
boosted to 250 hp max (realistic is 200-225, but I dont want to 
marginalize capacity). Assuming no more than 20 psi and no undue flow 
restrictions.
 
Any takers on the math?
 
Why: spec'ing a racemate direct drive water pump and alternator.. I 
intend to order in the next week and want to select the right one.. or 
the "most right" one.
 
Dave
