First off, why would you be running an electric water pump on the street? There's no way it will move enough coolant to cool the motor compared to an engine-driven water pump. If you think you are going to pick up some horsepower by not running a mechanical pump, you're mistaken, especially if you did by accident find an electric pump that would move enough coolant. It takes the same amount of power to move the coolant, whether it's mechanical power from the crankshaft or electrical power from the battery. Since the battery is recharged by the alternator and the alternator is driven off the crank, you're still using mechanical power to drive the water pump. The main difference is that you've invested way too much money in an electric pump, money that could have been used to actually improve the efficiency of the motor.

Secondly, you have the motor all plugged up. The crankcase has to breathe in one manner or another, whether you use one or two breathers open to atmosphere or one breather open to atmosphere and the other plumbed to the intake manifold through a PCV valve.

I'm surprised that you haven't complained about the oil dipstick being blown out of the tube and I'd also be a little surprised if you didn't hurt the rings when you overheated the motor.
