Anybody know a real rough estimate or calculation from an engine book on how many btu/hr are introduced to engine oil based on rpm? I may just make something up, but we are trying to figure this out for a project for class.

When I go to work on Monday I'll take note of the oil and water temperatures versus the exhaust temp, I didn't think of it that way before Mike mentioned it. On the plus side we're using a bunch of LS1's. (IMG:http://www.frrax.com/rrforum/style_emoticons/default/thumbup.gif) But in the negative column we run the engines with almost no timing in order to increase the exhast temps. The oil, water, and dynos are run through liquid to liquid heat exchangers so I'm not sure how much my numbers will help you. I do remember that our exhaust temps range from 850 to 1000 *C, so 10% sounds like a better number than the 80% I said last time. (IMG:http://www.frrax.com/rrforum/style_emoticons/default/huh.gif)
