Where does everybody shift to get maximum power for the Z?

At what RPM do you notice the power flatlines?

 

shift at redline so after the shift you are at peak HP in the next gear....

 

Depends, max torque is at 4000 rpm, and max HP is at 6700. Take your pick, but choose wisely

 

I usually shift just over peak torque.

 

Then you are loosing a lot of horsepower.

 

I must be weird then, cause I usually shift around 3-3500RPM. I also find myself shifting from 2nd or 3rd gear right into 6th, because at that point I'm already doing the max speed limit (city driving)....

Ahhhh, the interstate....

 

I don't think he's talking about sunday driving.

For maximum performance, shift at redline.
