Thanks Lowell... I too thought the chiller should do the job.

Regarding the expense of an oil cooler...

I've been running race cars for 30+ years... 600+ hp, 9200 rpm shift point etc... and the oil coolers I use are rock solid, but FAR less expensive than an oild cooler purchased form a supplier to us homebuilt guys... for example:

This cooler (a 10 plate Aero Classic oil cooler) is $262 @ Aircraft Spruce:

While this cooler (a 10 plate Derale cooler) is $77 @ Jegs... and it includes the AN fittings:

Here's another one I've used (a heat sink transimission oil cooler)... it's $65 @ Jegs:

From my experience there would be no reason not to be VERY confident the coolers I've used on race cars are every bit as reliable as the expensive ones.

Thoughts?
