Which oil cooler is the best?

Fountainhead

I mean in DD situations shouldn't the oil reach at least 200F to boil the water off? If the oil remains too cool then won't the water content cause problems? I guess for DD you get the <25 row.

Rusty

Once the oil temperature hits around 100F. The water trapped in it starts to evaporate. By the time it gets to 200F. It's gone. Where I retired from. We used to warm the oil to 110F. before operating the equipment. And kept it under 190F. I wrote the SOP on it.

From what I have read so far the best option is to purchase a oil cooler with the correct row for your 370Z for what you are using it for.

Rusty

From other peoples experience on here. Get a 34 row cooler, and don't second guess yourself if you should have gone bigger if you had gotten a 19 or 25 row cooler. There have been many times of me reading where people had wish that they didn't go bigger to begin with. A 34 row with a thermostatic plate and you're good to go.

Yep once water begins to boil, it changes state to steam & can not get any hotter in liquid form. Pressure in the pan is not enough to raise the boiling temp more than just a few degrees so as Rusty states 110 Deg F is more than adequate to boil off the water. Also most modern oils / Synthetics are designed to flow/protect at very low temps

You're close. You should work in a power plant. Have water temps as high as 1,500F, steam temps of 2,000F. To get water temps that high. You have to have it under pressure. Pressures high as 3,000 psi. To get temps that high. Most use a 3 element boilers. For our discussion. Water starts to evaporate at around 100F. By 212F, it's boiling. And the little moisture that is trapped in the oil will be gone at around 150F to 170F. Unless you have popped a head gasket.

Yep the pressure makes all the difference, the same as you can boil water at 0 Deg in a vacuum

Yeah, I used to do that trick when teaching noobs on making steam for power generation. Teaching steam tables was a headache. And to get across the difference between wet steam and dry steam.
