A sunny day will help warm the track surface.

A high barometric pressure also helps improve performance, and low humidity is also desired. When the Density Altitude is 0 feet or less, the conditions are very favorable.

And, of course, proper track preparation is essential as well.
I think it was like 44 degrees. And we don't know what time of day it was and if the tires had been warmed up at all. Yeah, my experience has always been that cold fresh air was better than hot air for engine performance! Combustion is much improved with more oxygen and less humidity! Ever try lighting a damp match? LOL

More tests shall come. I respect the Boss for it's intended purpose. It just so happens that the ZL1 suits many more purposes and does all well! Superbly as a matter of "reported fact.
