What is your opinion on oil coolers air/oil or water/oil. I know art 

is running a water cooler oil cooler and it works fine my concerns are if 

you should lose water cooling there goes the whole system water and oil. At 

least if you have your oil cooling system air cooled you have some cooling 

of the eng to get you safely on the ground. Also less lines to hook up 

without the water going to the oil cooler.I have a meeting with my neighbor 

Waltrip the nascar fellows cheif mech to talk this subject over will be 

interesting to see what the nasca boys say and use. I can build it either 

air/oil or water/oil. What are the opinions out there.thank



     Regards

I tried the very large Callies oil to water cooler on the race car and had very good results. The water and 



oil temps became the 

same. However the 31" by 19" by 3" double pass aluminum radiator was not adequate to dump all of the heat.



So, I cut the water manifold off of the cooler and used it as an air to oil cooler for the transmission. 



I ended up with three 13 row Setrabs for oil cooling.



There is only air cooling. There is nothing else. If you can dump the excess heat through the water radiator,

then its a great idea, and works just fine. Oil temps above 160 degrees cost power. The cooler the better.

You will need 1/3 more water cooling than you started with to make it work. You cannot fool Mother Nature.
