We missed you at the RCC meeting last night.
I hope that you are feeling better soon.
We all talked about oil coolers
I found the following Frugal cooler:.

Subject: [RCCTrackers] Re: Hot engine oil temperatures
Thanks for all the insight that you have experienced. I agree with
everything that you have said. But, on the otherhand, Porsche has
been running an air cooled engine for years with an oil cooler that
works....as well as other manufacturers. My engine coolant
temperature has never been a problem...that I'm aware of. I will pay
closer attention next time on the track. Pfadt does have a nice
system, but any solution that requires $800 plus installation for 20-
40 minutes of track time is for the " I have nothing better to do
with my money". Sorry that I'm so frugile, but there has to be a
more
economical way. Once the weather clears, I plan on putting an
auxillary fan on the stock oil cooler with a temperature
activated
switch. I estimate $150 for the complete package. If it works I'll
sell the idea to Pfadt, Dewitts, and Rippie.
