Great source for thermostatically controlled oil bypass:

If cannot package (due to headers, frame, no LS engine...), can use this:

Having oil-to-water heat exchanger also helps warm up the oil after cold start, but still recommend having t-stat to control flow until desired temps are reached.

Nice feature on all these type bypasses is they never block flow to cooler, just open a 'bypass' to allow oil to return to engine prior to reaching temp set point. This allows some flow to always occur through cooler, so by time temp point reached and bypass is closed, not hitting engine with a slug of cold oil.

Since this discussion is already going here, does anyone have any thoughts on this. http://www.frsport.com/Greddy-124011...t_p_12814.html

Remote filter with built in thermostat, seems like it could solve some plumbing/packaging issues.

From the description is sounds like it's just a thermostat and not a bypass. So as Dave mentioned, you'll hit the engine with the cold oil that was in the cooler when the thermostat opens. Maybe I'm reading it wrong though.

Here's what a couple people I know are using and C&R says it should work good to help control oil temps with the bypass valve.

Do you feel that the fan power is needed for cooling on the road course ? I always kind of thought that 85+% of the cooling was done at speed and the fan was mostly for < 40 mph. I assume you overheating concerns aren't so much at idle since you keep mentioning the road course and HP.

Any thoughts on that ? IOW, at your average road course speeds do you feel that the fan is still doing significant work ?

With a 5 inch thick cooling stack the high powered fan is a key part of the cooling package.
