[2000SoCalBoxsterS]

O.K. I plugged in my variables. Shift ratios same as on your sheet. I have 18" wheels with 265/35 tires on the rear. My owners manual only shows my torque in NM at rpms. They look like this:

Enter Engine Speed, RPM Enter the engine torque, ft-lb
1500 240
2000 258
2500 265
3000 280
3500 285
4000 300
4500 302
5000 302
5500 300
6000 290
6500 265
7000 240

But the Drive Torque Chart output doesn't look right? The Wheel Torque Lb-ft scale is in thousands? Showing me that for example at 25 mph I am at 3500 Ft-Lbs? How am I supposed to read this? Use this info?

The stats on my Boxster from Porsche say I have 250 HP / 225 Ft-Lbs at 6250 rpm
Seems to me based on the graphs in my manual that 4,000 to 5,000 is the peak power band.

What am I missing here? I'm not being critical I just don't understand and I want to learn this stuff.
