Your red line is basically what you shouldn't spin your motor past; it has nothing to do with tq or hp peak.
Sounds to me like some people should hit the books!
Keep your cents, you'll need them to help with your education!

Um, maybe you need to re-read what was written and think about what you said for a second. For one, neither one of us said anything about spinning a motor past redline. I'm sure that that was a simple mistake and you got confused when you were reading the previous posts. As for your theory about shifting at peak power, it really depends on the power curve. Just because a motor is past peak power doesn't mean that it isn't making substantial power beyond peak. For example, a motor might make a peak power of 600hp at 6500 rpm and drop down to about 550 by redline of 7500 rpm. Shifting at 6500rpm will drop the car to say 4000 rpm where the car makes about 500hp but waiting til 7500 rpm will drop it to around 5000 where the car makes 550hp. Shifting at redline keeps the car above 550hp at all times but shifting at peak would drop it down to 500. No question as to what shift point would be better.
Maybe you should take all of the change and buy yourself an education.
