EASY Nuke!
Some things in life I take for granted, like your engine needs to be at operating temp prior to getting on the track. (that is why they have warm up laps) and yes a 160 thermostat is OK, as long as your
oil temp is above 200. The problem is that the
oil will not function properly at cold temps. It just can not burn off the containments that get picked up along the way. I in no way endorse getting on a cold engine, or cold tires for that matter. Warming up your gear is a given (I think) for most of us out there that use our cars on the track. I think that if you look into your specifications your
oil pressure is way to high for that motor at those temps, that was my point.......
