While fooling with aero mods and cooling I have found some puzzles regarding water pump that maybe someone can help with. Seems it belongs here instead of Tracking thread.
1. I cannot find any information on our water pump flow rate per 1000 rpm. Mishimoto picked 40 gpm in their radiator testing, I assume at high rpm, as typical maximum. That sound right?
2. HP consumed by centrifugal wp looks like 3-6 hp on other performance cars, sound right for Fist?
3. 300 hp converts to 12,772 btu/min. Most of the experts say about 1/3 of this must be handled by engine cooling, water pump and radiator. So we have (for most of us) around 4000 btu/min maximum to waste via radiator.
4. Some racing guys increase water pumping rate to increase cooling, but I cannot find any water pump upgrades for us. Are there any?
5. Anyone messed with "high flow" thermostat to increase pumping and cooling? Is there even a high flow thermostat made for us?
Thanks
PS: According to all the math, stock radiator can handle 4000 btu/min easily. Is a bigger water pump a potential solution to track overheating?
