I disagree with that too. I think adding a SC will transform either one into something you always thought your 928 should be.

You know more about it than I do, it was just a hunch I had. Didn't mean to start a whole thing here.

I have an early 5 speed and love it but can imagine the more power i put through it the tougher it will be the keep the momentum up btwn shifts.
Again I have an early car and know the later cars like your's shift much quicker.

My '04 Cayenne S also has a Benz built transmission BTW, it has been trouble free. New Cayennes i think do not but don't hold me to that.

Stick shifts are fast becoming a thing of the past, it is sure nice to have one in a 928.

It's definitely more difficult to drive a 5-speed fast than it is to drive an auto and even more so when supercharged, but that's part of the fun. One missed shift and an equal auto car will blow by you, so you need to stay sharp. I would however love to have a 7-speed PDK in my 928, although even that would probably take some fun out of driving the car.

Here is what happens when you try to shift a manual 928 too fast.

Manuals give a more immediate response to your foot on the gas, and you may feel faster than you are - you need to have smooth shifting. Autos let you just slam the gas peddle, and you may think you are faster than you are - you need to have it set up right.

I think many are driving autos that are not set up right, and they don't realize it. Low ATF and slack cables make a major difference. If you are topping off ATF without running the engine/trans, then you are probably low and slow. Check your cable slack and set the ATF level correctly with engine running, and you may find your car is more eager. An auto that feels smothered is not set up right.

I have plenty of both auto and 5 speeds and the manual cars are dogs to drive. Has to be the worst gearbox ever put in a Porsche.
The auto cars are super fast, smooth and an absolute pleasure to drive.
The "Rogerbox" cars are far better with no difference in performance at all on equal cars.

I guess that is why we sell so many short shifters and Lizard shifters as all "doggybox" manuals are desperate for any inprovement they can get 8>)

PS: I am not biased at all

The worst part of the manual boxes is the shift linkage, and the hydraulics.

I cannot begin to describe how I dislike that factory design that somehow can mysteriously get air in it.

Replace the shifter with mine from Roger, and when the clutch hydraulics are working properly (or you install a floor mount pedal), it becomes a completely different car. And the autos have their places for sure. But I've had both autos and manuals, and the manual gets way more use from me!

The short throw shifter made a big difference for me in the way the car drives. Stock throw is too much! I can only imagine how the short shifter would perform on a transaxle that is in good shape (mine is half broken ).
I do also wish the clutch pedal travel was shorter/lighter but that's not happening.

As to the throw of the clutch pedal, this can be greatly reduced by a 100% correctly adjusted int plate.
Though reducing the throw from a larger bore would only increase pedal pressure. And past that, there is bugger all you can really do.

Drive a manual 911 before 1987 and the early 928 manual is a dream to shift.

I have owned a '86 Carrera for 13 years prior to the '83 928 manual and can say the 928s shift linkage is way nicer than the 911s.

First thing i did when i got the 928 home was read the factory workshop manual and install a new ball cup bushing,(it was completely gone) adjust the clutch int plate, and then really blow the dust out with compressed air. I lubed the throw out bearing with Wurth spray carefully and closed it up.

I drained the gear oil and re filled with 1/2 Dexron ATF and 1/2 75/90 wt Valvoline gear oil in there and it shifts like butter.

I love my 928 5-speed. I am more connected to the car with it.

It seems some guys here think that talking to auto owners is the equivalent to addressing a group of old ladies at a sewing bee. News for ya, most of us auto owners previously owned sports cars with sticks. There is no talent to driving a stick well (assuming you are halfway coordinated).

It is antiquated technology. The top cars have moved on and removed the clutch pedal. When you drive an auto the engine is floored the whole time while accelerating, when you drive the stick that is not case. The best driver can not match the efficiency of the 928 auto shift and power delivery.

The manual has 1 advantage, display driving. If you want absolute control to drift or control the back-end thru power application then the manual is it.

Go back to sewing.

They guy that came and took my car out yesterday couldn't get his head around the automatic and is probably going to pass on it. Even with the $hit your pants power my car has he didn't feel engaged in the drive and felt my automatic wasn't responsive enough with just the pedal. I told him to just use the gear lever but he didn't feel that was the answer for him.

Both have their pluses and minuses. I hate the auto off the line with the 2.20 gears and the huge ratio jump from 2-3. Other then that I like the reliability and very impressed with the amount of power it can hold.

1) A person who wants a stick will not even consider driving or owning an auto.

2) Snookie was the only girl on the Jersey shore who knew how to drive a stick. She did it badly. (see driving episode)
