Imagine . . . adjustable radiator louvers?

hmm. the new Raze heated bars completely shut all flow off to the rad unless temps hit 180F .All flow goes through the bars, So the radiator covered or open will make no difference.

The thermobob diverts the coolant until 180 degrees also however covering the rads still makes a huge difference. Someone did a good job of explaining why in a previous thread. Has to do with the whole “heat sink” thing I believe.
