Optimum shift time in Boxster S

[SinnerDC2]

I come from the honda/acura world where we always shift at redline without any consequence. I shift right before 7,200 very often in most gears.

I agree with Bruce Lee for all of the reasons he lists. It's only common sense. Try driving your Boxster by doing all your shifts at 6K + and if you're smarter than a 5th grader you'll quickly understand why it's not practical unless you are racing on a track.

If you want to know, take it to a dragstrip and do timed runs videoing your tach. Real life stuff, not theoretical. I race sailboats and VMGs and performance plots are one thing, but the race course is where it matters. Obviously one can extrapolate values from the Porsche owner's manual and determine intersection points btwn hp and torque and factor in variables like timing and lift off and such, but whatever....

That's too technical. Shift it when it feels good - for me that's just before fuel cut-off (because I dislike the feeling of the engine stuttering due to fuel starvation).

6000, 6500, 7000, whatever, just keep it pegged until it feels good to you, then shift and do it again. That's the "best" time to shift - the point when you're having fun - and the person beside you is smiling too (or keeping her eyes closed).

Sorry if this isn't technical enough. :dance:

Cheers

I agree. You explained it perfectly. Forget the technical stuff and "use the Force Luke!"

Thanks for backing me up 2000SoCalBoxsterS you're on my good guy list too. You know me by now, if you have a Pcar ...... floor it ....... and drive safe. Can that be done .......... yes! I do that all the time and my family and friends just love it!

Ciao (and no that doesn't mean anything more than I like that word)
