Best oil cooler and temp difference????

[Curt C.]

Morris and others running 210 - 220 oil temps. Where is your temperature sender installed exactly?

We have a temp sender installed in the scavenge line going back to the tank..... coming out of the pan......

And we have a Oil temp sender installed going back into the motor after the thermostat.....

Two.... out and in....temp....

Looking at heat exchanger radiators, basically a normal radiator with an oil cooler built in to the bottom tank, C&R Racing make radiators for Nascar, hit something and it all goes!
Aeroquip make an oil cooler that goes in the bottom radiator hose, and has two -12 fittings for your oil lines, this may be more manageable than an all in one radiator as first mentioned in the post, and is probably similar to what "Jac Mac" mentioned earlier in this thread!

Morris,
I reckon that a heat exchanger negates the need for a thermostat, as it would more than likely speed up warm up and balance the different fluids simply!
The only downside is not having the nice air cooler in the front cowling

You are right on the mark...... however...the Cobra doesn't have much room for a heat exchanger in the bottom radiator hose.....

Just not much room for anything....

Also the heat exchanger will only get the oil up to the water temp on a cool day...... which is not hot enough..... needs to be 210*-220*.....

Heat exchanger will maintain oil temp up to water temp on cool days....

On Hot days ....no problem....with getting heat...in the oil.....

Just this to add: The oil to air coolers have shown to be more efficient on our race motors. On larger tracks, with the oil cooler in the radiator, water was 200 and oil was 250-260. After switching to a large, oil to air cooler, water is ~200 degrees and oil is now ~230 degrees...considered very good in our application.

So for every day street driving, do you guys not recommend the oil cooler?

For everyday driving I've bought a nascar type C & R alum rad with heat exchanger--it puts the oil temp where I want it and I think it will even be acceptable for a few hot laps at St Louis, Road America or the other road coures

But if its in competition, My son Corey will be driving it on the road courses and I'll drag race it--when and if we go to Bonneville we'll both take a turn
at the 200mph mark
