After a long search of two different computers, I found my original notes written to the management of Fluidyne in September of 1999, after Van Dorn and I finished our hot weather testing of the Fluidyne Radiator

My memory as to the ambient temperature during those few days of testing was not so good. In an earlier post, I said it was 115°. Actually the hottest OAT we observed during testing was 111°.

The memo to Fluidyne has been converted to a .pdf. It's an interesting insight to the kinds of stuff the original Auto Masters and myself were doing 16 years ago. At the end of the memo is all the testing data. Tests #8 and #9 were both done on CA SR74 in the "7-Level Hill" section and were run uphill at near racing speeds, i.e.: about as hard as I could drive given I had to stay on the right side of the road. The distance from my starting point to the top of 7-Level was 4.9-mi. I included a Google Maps screen shot of the course used in testing. All the mountain road testing was done uphill.

The radiator uses for that test is still in my car today. The only difference in my cooling set-up now is I use 100% water and RLWW rather than 75% water and 25% Dex-Cool.

If anyone has any questions, post them and I'll try and answer.
