I have a hard time believing one is going to get a 40F temperature drop across a TB. But it's been a few decades since I studied such things.

Used to see carburetors ice up a lot at high rpms. When ever you have a pressure drop. You will have a temperature drop. This is how A/C works. Freon going through an orifice.
