I was watching Daytona 500 and one or 2 of the cars were steaming a little at one point.
1-
One of the announcers said not much air is getting in since they are drafting ...
I can understand this one.
2-
Later another guy said they tape off the grill or parts of it to go faster.
Is this for aerodynamics or for keeping the engine hot? it kind of contradicts #1
3-
Later they said the temperatures are dropping so the cars would be able to go faster.
Does this have to do with tires and the track and/or increased amount of oxygen? otherwise colder air is denser if we are talking aerodynamics and cooler engine temps (if any and/or significant) contradicts #2.
I can't connect some of the dots. Please help!
