Subject: Re: Fw: [FlyRotary] Re: Fw: Water temps

This is where I get confused:

said previously,

-ideal water temp = 160*~180*F

-ideal oil temp = 160*F

If we are cooling oil with water that is at best hotter than the ideal temp of the oil, then are we not adding heat to it rather than removing it?

If we are trying to cool oil, why would we feed the highest temp water to the oil/water cooler rather than the coolest temp water by tapping into the pump housing where it enters the block?

Based on feedback, the water entering the block may be as low as 150*~160*F, would this be cool enough to do an adequate job of cooling the oil?

Also, which model of Mocal is being used?
