Read many threads on the installation of an oil cooler. Seems like a lot of guys see lower track temps of around 280 - 285 as a result.

Not too big a differential for the effort and cost. Anyone try installing an electric fan blowing on the cooler for better results? Would also allow other options for cooler location.

If you mount the cooler in the right place I don't think a fan is better.

I believe I recall seeing one of these (or an item like it) installed on
the pass side near the fender gill vent of a Superformance Daytona
Coupe powered by a Roush-built 427 Windsor in articles about the car
that appeared circa 2006. This example does not show the cooler
but it may have been the feature I recall.

Is there a particular issue that you wish to solve by adding a fan?
Low speed cooling, increased mounting options, improved aerodynamics?

Keep in mind that a fan may/will obstruct air flow above some speed.

I use them on my trans and diff coolers blowing out the rear

The issue I have is the temps people are realizing after installing a cooler are so close to temps without a fcooler they are hard to justify.

INstalling the right cooler, in the right location, will give you a large reduction in temp.
A fan will not move as much air as being properly positioned in the airstream. Fans only good at low speeds (not where you are having an issue) or where there isn't a lot of airflow movement at speed.
I changed out my Mocal air/oil cooler for a water/oil cooler, and dropped more than 30 degrees. Now running low 240's.

Jvett,
I like the way you think and then make it happen! I have been working on that type setup for some time, debating to use fans or not, ducted air, low pressure evacuation (no side windows so always plenty of air in the cabin and license plate area opened up and screened)

Same cooler location and heat sheilds for the lines as well

A friend of mine tried the natural ventilation idea with the windows down and no fans and was not satisfied with the result. he now has fans.
Mine is not finished as I have not hooked up the diff cooler yet or ducted air from the trunk lid yet but trans temps stay under 260 deg. with the fan just circulating air from the rear.
B&M sells the plate style coolers with fans attached

Fans are not necessary if the air is managed properly. Blowing out the rear will cause stagnated airflow above 40 mph. Switch the direction of the fans and the temps will drop, or get rid of the fans all together.

We have a fan on the GT2 car for safety only, which turns on with oil temps over 110C.
