This is a VERY specific use for the engine. I highly doubt that oil temp will be an issue as the engine will idle for a few minutes, run WOT at full load for a minute or so (1 mile), then idle back to the pits. I expect that the bigger issue will be getting the oil up to temp rather than overheating it (I may install an oil temp gage but haven't decided that yet).

I DO appreciate your concern but this is SUCH a weird application that different rules apply. If I take the truck to Bonneville (not likely) I'll have to rethink the oil cooler issue.
