As the engine speed increases past 6,800 RPM the engine power output decreases. However, there is still enough power to continue to accelerate it is just at a slower rate.
Also, keep in mind that at the redline you have to switch into the next gear. When you switch gears the engine speed drops. By raising the redline you also raise the initial engine speed of the next gear.
For example, if you switch gears at 6,800 RPM the engine speed may drop to 3,300 RPM. Whereas, if you waited until 7,500 RPM to switch gears the engine speed drops to only 4,000 RPM. If the engine makes more power between 6,800 and 7,500 RPM than between 3,300 and 4,000 RPM than you are better off waiting until 7,500 RPM.
