I picked up a little over a tenth on a great day a couple of weeks ago over the heat of summer.

Usually a tenth or two. I still have the stock hood so I don't get the benefit of the cooler air until later in the run. Regardless of outside temp my air inlet temperature is usually 130-150* on the starting line, it then tapers down through the run and drops closer to ambient.

Heat of summer July and August...high 9.8s to 9.90s. Decent summer air...9.70s. Good fall air...9.60s or maybe 9.50s if it's real good.
This is N/A on pump gas. My old motor that ran on C12 didn't seem to fall off as much in hot weather. Possibly due to the fuel?

Temp can make a difference - if you jet up for it - which most don't. Still can help a little. Big difference comes with a change in DA.

I try to keep it simple. When the weather turns hot in the spring, I lean the carb out 2 jet sizes front and rear and don't bother it again until the air gets good again in the fall. I've tried chasing jetting for different conditions (years ago) and honestly never seen much change. The only time I'll stray from that is if I'm going to the track on a day I know the air will be extremely good. Then I'll try jetting it up more for a good timeslip.
