Say that's true how do make the most power there ? torque of course so peak torque at 4,000-5,000 rpm gonna give the most under 5,000 rpm power plus the most 5,500-6,500 rpm power for the few seconds your there.
You may never go above 4,800 rpm, but I do get and agree with what your saying, build it so it works best with how you drive and how you want to play with that power. Everyone is different and wants different things it's up to the OP to figure out what he truly wants.
