Were you cooling the high pressure oil coming out of the pump or after it came out of the engine on its way back to the tank ?

Is there a preference ? Does it make a difference ?

I run a oil/water cooler on the pressure side before it goes into the engine. I like this because as you mentioned it also warms up the oil which is good for a street based car, but I was thinking of adding additional cooling capacity via an air to air. But packaging means I would like to put it on the low pressure side. Thoughts ?

That isn't actually what we used, but I saw it and thought it would be more along the lines of a streeter.
You just have to trust that the thinner unheated oil works better in cold temps than trying to heat thicker oil..... I promise. There would be nothing wrong with a pan heater though.

It really didn't matter as long as we passed sufficient volume to avoid starving the suction side. It really doesn not take long to heat a 0 or 10w oil. I guess if you are cruising in sub zero temps..... We also found power with a particular brand of dino oil over every synthetic we tested. It was the "fake" synthetic, if you will, the "superclean" crude that many companies pass off as synthetic.

By the way..... you guys do know they make a thermostatically controlled bypass, right?

Where are the updates? Its been 10 days, we need a fix.

I had Dewitt’s radiator custom make me a radiator core and intercooler core. The cores nest together to make an efficient package. The assembled the cores with tanks and mounted them togther. I had it made 23 inch tall and 24 inched wide to fit a Cadillac SRX turbo fan and shroud. After a long conversation with C&R they supplied a 10 kW oil cooler for the end tank. Dewitt also built in the power steering and transmission coolers. It maybe a bit overkill but I want to get the temps under control on the new car.



The top two coolers are power steering and transmission. The lower cooler is the engine oil cooler. Using oil to water coolers it will help heat and cool the oil.



I plan on mounting it as an assembly on Duramax Diesel radiator mounts. This thing is off setting some of my mass savings.

Dewitt did a killer job of building this deal. Having the ability to custom make everything makes a very nice package.

Doesn't matter how light it is if it's over-heated and parked. Nice bit of creative engineering.

Would love to see what the coolers inside the radiator look like.

Hey Mark, just curious the reason for using the Caddi fan and shroud instead of the Mark VIII fan I've heard so much about. Thanks Shawn

Mark - have a few questions regarding this design

1. On the left side with the three integrated coolers in the crossover tank, are there just lines running inside, or are there fins with a line curving through them like the heat exchanger on a refrigerator buried in there?

2. You mention getting an oil cooler that is stainless steel - is there a particular reason that SS was chosen as the material v. aluminum? I would think conduction across and convection through an aluminum part would be better, certainly conduction as SS is a poor thermal conductor.

TIA.

End tank heat exchangers (oil) is as shown in this link

Other coolers are similar for power steering and trans.

Plate type is much better than tube-and-fin heat exchangers with respect to pressure drop and heat transfer.

One reason for stainless is for strength to withstand 100 PSIG oil pressure without resorting to thick wall sections - which would be required for aluminum.

thanks Dave for the link - those plate coolers are pretty cool and it makes sense putting those in the tank and thanks for the note on SS v. aluminum v. pressure.
