I know that I’m old, and don’t know everything, but my FAST XFI LT1 EFI car is faster at 50 degrees, than when warm. Money spent for track rental testing was involved. Likes different timing and air/fuel tuning when that cold. Carbureted cars would likely gain the most with different jets. Or, a “heads up” carb jetted for it.
I have not had a car that was not faster cold.
FAST XFI has coolant temp correction tables/capabilities you can dial in for using the “chiller”.
Don’t have to touch a thing if you dialed those parameters in during testing. Just chill it & run it. Worth well over a tenth.
