Reverse cooling - how to?
Reverse cooling - how to?
(OP)
Hey guys. You'll probably laugh at me, but I want to try and set up my Twin turbo 302 Ford efi with reverse cooling and figured I'd ask all of you "NASA types" what you would recommend. I would like to use some type of mechanical water pump and have been looking into some of the pumps used in marine boating engines. It would ideally be a remote mounted mechanical set up to push the water into the intake/thermostat location and then come out at the previous location where the original water pump used to push it into the block. I would then use a "boating style" thermostat housing to bring the the 2 sides back together, meet the thermostat and send it back the radiator. I know you're probably laughing now, but I'd really like to try it. Any ideas or suggestions are GREATLY appreciated. Nick

Better make sure you plumb it carefully to eliminate steam pockets in the heads or you will have big problems. I recall that 302's may have a gasket restriction as designed that might require some well thought out modifications.

The biggest waste in a belt driven pump is not the belt drive, but the fact that it is running all the time the engine is running, and in a fixed relationship to engine speed, not thermal load

The bonus with a electric pump is that it pumps the correct amount of water, on a mechanical system when the engine reaches +-3000rpm, the pump is at its limits, from there on its just a waiste of energy.
I have an electrical pump on one of my cars and it works like a charm, you can not really notice the extra load from the alternator, however you do notice the extra power from removing the mechanical pump, so it does not matter how effecient what is, it still works better, only problem is it is a bit expensive, and does not always last as long as mechanical pumps do.
