Does your GZ run better in cooler weather?

Just wanting to see what others have experienced. I've noticed as the weather gets colder here in Florida, my GZ has a different feel. As I run through the gears, especially into 5th I have noticed a bit more "performance", responsiveness to the throttle.

Just wondering if anyone else here has noticed this or has an opinion as to why this is. My guess is the cooler air...

Cooler air is denser and will give you more bang for your buck with carbed engines.

Esp cool DRY air.

You say "dry" air, but I seem to remember that the WW11 Corvair aircraft had a booster,to use in emergencies, that injected water into the engine, to give extra mph. Although, if it was used, the engine had to be stripped before the plane flew again.

That was so an engine that's being run very hard could do so without hot spots inside it causing predetonation of the air/fuel coming in. (generally supercharged, turbocharged and very high compression engines.)

Talk to any racer. It's the cool dry days that you get your best power.

I would think moist cool air would contain more hydrogen and oxygen for better power with a naturally aspirated engine. Turbos and supercharged engines are a different matter. Water injection for hard working aircraft is probably ideal.
