Optimum shift time in Boxster S

[Brucelee]

Yes, you should run the car at redline at all times. I am told that the car will last much longer if you keep the pedal to the floor always.

If you can keep the revs between 3 and 4k (blip the throttle) I think you'll find it will perform nicely; however, running it up higher all the time will surely make it feel faster but it cannot be good for the car to be run up to near redline on every shift!

And yes, I know Brucelee was only kidding.

[David N.]

Pretty sure BruceLee wasn't kidding. Although keeping the throttle pinned at all times might certainly be overdoing it, the engine does need to be revved up and down, at least above 4. It clears the valves and simply allows the engine to wear correctly.

What you also need to consider is when is peak TQ? By keeping the motor between those two peaks, you should have the most power.

You also want to not run the car to redline because, unless the HP and TQ curves show otherwise, peak HP and TQ will drop off (relatively) at that point. I know in my stock 911SC, peak hp was somewhere around 5200rpm and fell off quite abit thereafter (redline was 6250), and peak TQ was around 3700 rpm for instance.

You also dont mention what you wish to optimize? I am assuming speed/acceleration as opposed to Fuel Economy

Uh, no, I'm really pretty sure BruceLee was kidding...

And Frodo and 70Sixer, you guys crack me up. Good on you
