What’s the purpose of the Engine cover?

Cooling, noise abatement, looks?

Primarily? noise and looks. May also help with dirt and dust getting around the top of the engine and sitting there.

Is it worth to remove it during a track weekend to improve cooling or does it have a role in preventing heat soaking and it should stay

I remove mine for autocross. When opening the hood between runs to help keep temps down it won’t (or shouldn’t) trap hot air. Does it make a difference? Maybe? Or probably not but it looks like it should. I have no evidence though and I may be completely wasting my time. ?‍

I think it would improve cooling. I don't have any evidence though.

I will say that my VN, I removed the engine cover, and the oil temps do drop 5-10 degrees.

Mostly for noise suppression. The HPFP is like 50x louder with the cover off.
