Having hot radiator air come out of the top of the sidepods like that will allow air to stick to the surface. Believe it or not, the kinematic viscosity of air increases with temperature, you can see this as the boundary layer on the ground increases on hot days.

It's not a huge change in kV, but may make enough of a difference to delay detachment.
It’s inconsequential, or you’d have to model the cars at different times of day / cloud cover, etc.
Ferrari, I believe, is quoted that this had a positive effect in the wind tunnel, which would account for any of that.
Dude, the air coming off the engine is ~140c, different times of day/cloud cover, etc is inconsequential if anything.
Are you going to keep rating my post negatively for calling you out?
I can bet you damn sure that the temperature gradient over the whole car varies greatly, bottom / top / sides, and it varies depending on surface temp, proximity to internal parts, paint color, time of day, sun intensity, etc. thus kv is highly variable, and 60% scale models, which Ferrari said this arrangement worked well with, don’t model this either.
I haven’t been around F1 cars to know, but been around enough Formula Atlantic cars to tell you that.
