Effects of DA on N/A motors?

This seems like the proper place for this thread…

So I went to the local drag strip this week for the first time in a long time, unfortunately I’m in Colorado so the track is at about 5800 ft above sea level. According to airdensityonline.com the DA at the track while I was there was ~8000 ft.
I had heard before that a turbo car can expect to add a second here compared to a track at sea level, so I was curious as to what kind of hit a N/A V8 would be expected to take…
