what are your ideal rpm shift points?
Just wondering what you guys consider the optimal rpm range to shift from
1-2, 2-3, etc
Do you guys also go to floor with the clutch on each up/down shift or just depress until you get a good bite?

3500 to 4200, the higher the gear, the higher i accelerate before upshift., Unless im under a tunnel then i let the rpms slowly reach 5000 in 3rd gear then i stump the accelerator to heard my intake noise echo in the tunnel off the other cars and cement.

For everyday driving I shift at around 3,200 RPM.
I used to put emphasis on making sure my foot is down as far as possible when shifting,and still do. I have only grinded gears twice in my Boxster. Both on dates...
Although I have noticed that the car is forgiving if your clutch pedal isn't depressed 100% of the way,just don't a habit out of it.

I like to drive around in 1st gear at 6000 RPM before taking off in second. This really seems to annoy the people waiting for the bus as I grin while driving past them.

these are higher ranges than i was expecting. have any of you had trouble with gearbox wear?
i just bought a used 986 and when i was having problems with 2nd i tried to get porsche to repair the box but when the dealer pulled the rpm report porsche said that the car showed too much activity in the upper range and would not repair the box. i am in the midst of fighting with the dealer to take it back (nj law says they have to take it back within 90 days but of course they are trying to find any reason not to).
so i am now curious as to how "pampered" the gearbox/engine rpm's have to be in order for porsche to be pleased with how you are treating the car.
i was shifting in the 2,500 range and i thought i was taking it easy on her but sounds like higher ranges are not disastrous.

These are higher revving engines=its ok to keep it in higher RPMs,3k-4k for daily driving. If you look at the manual it should say the recommended shifting points.
If the dealer is saying that the car has too much activity in the higher RPM range tell them you want to know how many times its hit redline.(they can only see how many times the car has hit redline,not where its driven RPM wise every second it's ever been turned over)
Good Luck!

Once it's warmed up it depends whether I'm driving to work or enjoying the twisties.
Between lights while driving the last leg of my trip to work (45 mph), I usually punch it in first, then shift into 4 th at about 6000 rpms.
In the twisties, I usually floor it and try to keep it under 7000 rpms in first and second.
BTW I ALWAYS push the clutch to the floor!

Ideal for me:
1-2: 6500rpm
2-3: 6500rpm
3-4: 6500pm
4-5: 7000rpm
5-R: 700rpm (jk)
Of course, with the wife in the car shifting is far from "ideal".

Hey Blink...you need to get in the habit of letting her go a little higher before shifting. The high compression engine wants higher rpms to keep it clean. I'll post a thread on it with a little more info, but you really should try to stay around the 4Krpm mark.

I've noticed that the shifts are the smoothest when you take her to about 4200......so as a daily driver the lowest I shift at is 4200......

4200 seems to be a very good shifting point for me on daily bases.

After reading what you guys posted it made me realize I drive like a little old lady. I shift about 3k on average.

Shift Points
For normal driving 3-4K in most gears. When on twisties or messing around 6K to 6.5K. One of the nice things about running my car on a dyno is that the graph shows hp peaks at 6.5K, then drops off noticably after that, so it does not help to take shift points above that if looking for max performance. At least that is what I see in my car with its mods,
Ed

I'm usually in the 3-4k range for normal driving, but will regularly push it a little harder. Although if I'm in the 6K plus range I can only do 1st and 2nd gear or I'm breaking the law, hit around 68-70mph in 2nd at 6500.

Does anyone know if this is correct for a 99 Boxster :
"201 horsepower @ 6000 rpms and 181 lb-ft of torque @ 4500 rpms"
If so, for maximum performance do I want to shift at 6000 rpms ( HP ) or 4500 rpms ( torque ) ?
Thanks !
Nick

Use torque to determine shift points. See this YouTube video for how to determine shift points:

I already have a Dyno. Now I just need to know the gear ratios. Mine is a 2003 986 Boxster S. Anyone know where I can find the gear ratios?

Holy resurrection Batman! This may be a record for reviving a thread. I was a wet behind the ears NOOB when this thread started.
A quick google search found this:
