Water pump over-speed... cavitation... is there one that can spin 10,000

328, so 2.8liter motor, maybe run two.

BTW, my simple engineering degree says, you can't turn a water pump at 10,000rpm and expect much water movement. At most, specific race pumps can only work to 8,000rpm. Your only solution is to use pulley size to reduce rpm.

Agreed

im thinking electric, two of them, and some switch turning second one on when hot

Viable, but probably going to need a check valve or two to keep the off unit from allowing leakage backwards.

Two of them under PWM control would negate that need. If ECU fan output is simple on/off then maybe can use a Arduino or R-Pi to scale the pump speed to the need?

Yeah, the KISS part of this project is gone.

Working on 2 separate belts again...

If it works, it's not complicated enough and lacks features!

Parallel pumps never worked for me. And I know others that it didn't work for either. Unless you go flathead V8 style and keep them seperate up to the radiator.
