lower = warmer
I've also noticed the coolant temp is running a bit hotter than it used to.
I'm seeing cruising temps (~80 km/h = 50 mph) around 200-202 F on the level. The cooling fan kicks on at 204, and it has been coming on on some gentle climbs. Pre-racecar, I was used to seeing ~198.
As a result, I've actually been doing less engine-off coasting on the highway, to avoid hot soaking the engine. Need an electric water pump to keep the coolant moving when the pistons aren't!
Is it possible air flow under the car has been altered enough to affect cooling flow? Seems like it.
