My 3.2 has plenty of grunt down as low as 1500 rpm, that's why I thought it would be kick to see how a well tuned 3.2 should be shifted according to the factory.

Joe

...only when she puts on the leather.;)

seriously though, why lug one of these around and baby the engine? Only reason I can see is if it is old and tired and on it's last leg.

gotta rev it up to at least 6K. mine see's over that on a regular basis.

Well, I don't think you should do that, but I don't think you should beat the crap out of it constantly either. It's just basic that the harder and more ruthlessly you use something, the quicker it gets used up and breaks. Some people seem to think that Porsche engines have received a divine dispensation that allows them to avoid that basic rule, but I wouldn't count on it myself... ;)

Joe, the shift light is not actually a factor recommendation. It's more about making the US happy for fuel economy to avoid the gas guzzler tax or something. The owners manual in my '88 had MINIMUM shift points. Every gear was a little different, but it was something like this

out of 1st 2600
out of 2nd 2500
out of 3rd 2500
out of 4th 2650

The CASIS lite can come on really, REALLY low. I think you can get it to come on below 1500. If you want to pay attention to the CASIS light then only do so at full throttle. Then it comes on at redline.

Assuming you have the 3.2L brain and wiring, it should be possible, but I think you'll need the tach out of a 3.2L car since the light is built into the tach. I'm not certain, but I don't believe the wire for the CASIS is something that turns a bulb on and off in the regular sense. I suppose it may work on an LED but again, I'm not sure.

carbs, cams and portwork on my engine so it revs up very fast. The 3.2 motronic motors feel kind of lazy to me so maybe lugging them makes more sense.

flame away.

No, I think you're right to a certain extent. Just depends on what you consider lugging,

ianc

I shift at a higher rpm than the 'idiot' shift light indicates - it seems to encourage more economy than performance. To me, driving at 45 in fifth gear feels like lugging the engine.

That's what I'm talking about...I don't abuse my engine, but if I'm at 45-50 mph, then I'm going to be in 3rd at approx 4K rpms...imo, that's not abusing anything or causing any unnecessary wear and tear....

A good way to find out where the power is in the rev range is to have the car dynoed. After I rebuilt my motor, I had the car dynoed becuase I timed the cams differently than they had been prior to the rebuild. The dyno sheet will tell you when the motor is making power and when it isn't. This of course is best for the track. As far as street driving, I rev it to 6k whenever the situation presents itself and is safe.:)

Perhaps this is overstating the obvious but the irritating little light isn't a "shift light" that comes on to tell you that a shift is necessary. Rather, when it comes on, it is saying that at your present speed and load, you will get better fuel economy if you shift to the next higher gear. You'll notice it comes on earlier at lighter throttle positions. If you have your foot buried pretty deep, you may shift before it comes on. It's only telling you what should be obvious anyway, once you get used to the car.

For all you luggers you'd better keep an eye on a lot of nuts and bolts. I think rear engine cars have a tendency to vibrate loose at low rpms. Probably akin to more oil leaks also.

Eric

between 7k and 7.5k. ;)

And probably the root of the chain tensioner problem... ; )

Grady? JW, Tyson, anyone else--- what's the details on this if true? thanks

Sigh... simply not true. 911 engines are pretty well balanceed to begin with and vibrations increase in amplitude with speed. Not the other way around.

For those of you with a 3.2 or a 3.6 that like to bounce it off the rev limiter every shift, I have two words for you:

Rod bolts....

JR

Yeah, but if you are going to do something like that then pick something that's a common failure point...

head bolts....

I have three letters for you ARP.:D

3 pages of posts and apparently I'm the only owner that shifts when the passenger screams louder than the engine...

Yeah I got to agree with you I shift at higher revs when the wife is in the car. For some reason she won't get in it any more but I find that relaxing. My car has 964 cams and better valve springs. I like to run it up above 5 grand when its warm. I cann't see why to bother owning one of these cars if your not driving it that way. Makes me smile everytime I get in it!

ROFLMAO! :D

The way i look at it; "Porsche" is the name of a wild lover who says things like "push me to the limit baby and I'll make you feel really good" Put your gum on the silly shift light and peg it!

What a great F****** thread this is....
 

... not only LMAO, but made me run out and drive.....!

Hummmmmmmmm........
 

Some very intresting thoughts here. May I give you some of my random thoughts on this matter.

Revs and a Porsche are are the same. When I am out driving and in the "mood" I shift when my bu$$ puckers!!! First gear is well, first gear. Second gear can put me in jail almost on any road where I live. The red line is 8000 grand so "bu$$ pucker" controls the foot feed.

If you are on the "top" end most of the time. Running big revs like on the tack. Put your check book between your foot and the petal. See my tought. If you have the budget, the disire, and the brain, run the "pi$$ out of the *****! !

Lots of "stand on it info here", not too much real information based on cubic dollars. Don't get me wrong, these motors spin like tops, and "love"it. simply love to spin. Gearboxes and the stuff down line cost too.

Someone chatted about lugging a motor and the stress. I don't think that it is the vibes, but the heavy loading and loading that stesses fastners. When a motor "lopes" it has to transfer large amounts of torque to the drive train.

I sure you can find a replacement lighted sign that say, "Pansies shift now".........

doesn't your cars with shift light use just a relay? My Scirocco does and I just pulled out the relay. Shift points are relative, it depends on the particular powerband of your motor. experiment with your shift points to determine what is best for your particular engine.

This thread comes up about once every year if not more often. While I have learned to drive my car a little more spirited since I bought it and never revved it up high, I don't understand some of you people.

Ian seems to make the most sense. Sure, rev it up, beat the snot out of it every once in a while, take it down the fun roads and wind her out. Go to an autocross or DE and clean out the carbon. But some of these responses are borderline insanity. Do you really rev to 6000 every gear, every time? To use Steve M's analogy: that's like not just having sex with your supermodel, it's like having wild monkey sex where you drag out all the toys, rubber sheets and leather whips. Fun, but freaking tiring if you do it all the time. Once in a while you want some fun, but don't need the whole enchilada. :)

Then again, this may be a geographic issue. Some of you live in places where you can wind it out a little more regularly. :)

I like your driving style. Post pics

...as much as I drive I also can't see any reason to have one of these cars as a daily driver. that being said, beat the snot out of it or don't why own one.

Glad I'm not in the market for a used Porsche right now!

ianc

I guess the future will tell which ones of our cars (driving styles) will need an overhaul first.. ;)

Randy - I know I've asked this before, but why the hell aren't you in O.T.? My goodness, that place needs some new blood.

By the way, where to shift? 6,500 RPM on anything designed by Butzi's dad. Anything above 6,500, and it should be modified a bit more.

Hard to say. My guess is higher shifts are better than lower. I think the real key is daily driving keeps the motors healthy - hard healthy driving is probably better, as well.

why the hell aren't you in O.T.

- wastin' way too much time right here....

or be born as an early S engine

for the record , i do not bounce of the rev limiter
and i don't redline every shift every time, would get boring

but i do rev happely , at least a few times every time i drive the car, and get a chance to rev, traffic permitting....

I don't know of another car that I would want for a daily. What car would that be?

You know, you're right. It's about time I move on... SmileWavy
