I haven't heard back from my message to APR but judging from the Dyno Graph it stops just under 6700RPM. I am familiar with the first gear being very quick or short. However you may want to keep this in mind. This is just a general statement but in most turbo charged cars they don't make very much horsepower around the redline. I believe its always best to shift right when the horsepower tapers off instead of redlining it in every gear. In a head to head race if you shift at the redline in every gear or the first couple gears and the person next to you with the same car and settings shifts when the power band tapers off, he will beat you because when he is under throttle he is making better use of the cars power than you are.

 

I just talked to APR and it doesn't increase the factory Redline.

 

Interesting info about turbo red-lines vs. power. Have never seen this in the literature. thanks.

 

yeah I know, I should have actually that most turbo charged cars power curve starts to drop as it nears the redline so its suggested to shift before the power curve starts heading south so that when you switch into the next gear your in position to maximize the engines power in the next gear and so on.

 

You can exceed the turbos range of efficiency at a certain RPM, boost 'tapers' off etc. Power may drop off dramatically at higher RPMS unless the turbo's modded accordingly.
