My engine issue

Most people aren't thinking that though. They're thinking peak numbers, more is better. Sure at the drag strip shifting after peak power will be better since when you re-engage you'll be higher in the power than if you shifted lower. But on the street or track I don't see it being worth it. That 600rpm and 1/10th a second you gained isn't going to turn your lap times into Michael Schumacher territory.

Besides, I'd have to pull logs and count time in this case which I've never done to truly know. If you're at 300hp peak at 7500rpm, shift and drop to 6000rpm and 270hp, how long does it take to get back to 7500? Then find the time it takes to go from 7500 to 8100 where you're losing power. Is that time greater or less vs the time it takes to go from 6000 to 6600? That should tell you no?
