Problem is when the motor is at speed,60MPH it is also making more heat, but still only getting 55 GPM. Electric pumps work fine for racing, but for street, not so well.
Belt driven pumps on the other hand can be overdriven ,taht is, a smaller pump pulley and larger crank pulley. In that situation, the pump can push 45-50 GPM at idle and 90-120 GPM at speed.
Fan not pump was the question
