I wouldn't want PSM in my GT3. Why dilute the driving experience?

I've found it to be annoying in the cars I've driven that had it. The only benefit I envision is in the rain or snow and my GT3 won't be seeing those conditions.

 

WTF are you talking about?

There is no PSM on '04 GT2. Where are you getting your information from?

Are you sure you aren't confusing PSM with PCM???

 

I think he is (thought PCM was PSM)... unless it's the same source that said a tip was available....

 

no confusion on pcm/psm.

lsd's with mechanical - as opposed to electronic - differentials are not compatible with psm. historically anyways. agreed. the gt2 also uses a very high threshold for differential torque before slipping making things worse.

my info from europe may be incorrect so i will confirm, but my understanding was that the gt2 can be ordered with psm as an exception. clearly many cars today mix lsd and psm (e.g. the cayenne), but i would think they all use electronic lsd's. i did not, when hearing of this gt2, inquire as to whether they had gone electronic or whether there was some other way of accomplishing it, but i have no doubt it is possible. just look at the complexities (so advanced it's simple, and somewhat opposite to the lsd) of the viscuous system used on the tt.

perhaps the situation i am referring to was more of a one-off, and not offered directly from the factory; i will get more information...

wtf is pcm anyway...hehehe

 

I was looking at the Turbo S order guide for our part of the world and, sure enough, LSD was an option. I have no idea if it is available in the US though.

A GT2/3 should be pure driving machines with no interference between the driver and the car. If PSM is a requirment for anyone, then a 996tt would be the better option.

 

Just last winter I was coming down Hwy 1 south of Stinson Beach on a rainy morning. Sheer cliff on one side, straight drop to the ocean on the other. Not driving at an excessive speed. Came around a blind corner and a friggin' tour bus was 2/3rds into my lane. Had to take emergency evasive action in very limited room. PSM kicked in, and, I'm convinced, really helped to save my ***.

I love turning off the PSM on the track and whereever else I safely can. But sometimes it isn't about "competence" or "improving your skills." It's about survival. And when that's the issue, I'll take all the help I can get.

 

amen.

 

seh1: who did you talk to? does he speak English? Does he know the difference between S and C? some people don't

 

on pcm:

in order to make the 996 interior more like the 993, i.e. one straight line across the dash, the console delete kit is a must. if you, like me, are willing to mod far but want to keep the stock temp control unit, one thing becomes clear:

pcm is not an option. period.

not on the carrera, not on the turbo, nor the gt2/3

on psm:

i believe i explained myself in my above post.

i find the above comments from the other side of the atlantic interesting. lsd is available on (perhaps non-us) tts's. this illustrates part of my point about possibilities, in that the viscous system on the tt works in very much an "opposite" manner to the lsd's, yet lsd is now an option on the tts. i'd be interested to see exactly how they work together on a viscous awd.

time to research...

 

deetz,

i relayed your comments to my friend in europe. he had the following reply:

you guyc in the uca have no fusking slue what you're talking about...

just thought i'd pass it along.

PSM can be turned off on the track and unless you are beyond 7* yaw and hiiting the brakes hard (save me), the PSM stays off, yes, it is even possible to drift. So about the debate of PSM, the guys that have it should know they can turn it off and get all of the enjoyment of the "pure experience" of understeer and oversteer regardless of whether they have awd. Just don't hit the brakes or it will come back on.

 

Could you explain this statement: ‘Downright Dangerous’. How so?

 

No one is making the argument that it overcomes the laws of physics but rather will correct a not so bad mistake that could turn out deadly to others (and yourself) on public roads - especially canyons and mountains. I don't use it on the track. That said, "dangerous" is probably not remotely accurate even on the track owing to it's very subtul and unobtrusive nature. Porsche's PSM is not like many of the others which yank control from you and put you in a position wherein you don't know what the car is about to do. Many other traction control systems "feel" pretty scary as they offset the balance of the car with very abrupt and aggressive intervention.

 

PSM doesn't allow for much slip angle. Therefore when you are going around a corner with the intention of a little high speed drift, the intervention of the PSM (cutting throttle and/or applying brakes) will upset the delicate balance of your momentum slide... at low speeds this may not matter much, but this can cause a rather dangerous situation, especially if you are on R compounds or slicks.

The only stability control system that sounds conceptually good is the BMW M Track Mode found on the M3 CSL, which actually allows for up to 15% slip angle before kicking in.

 

Unless it is on a real tight course, the GT3 or GT2 would be hard pressed to even stay close to my turbo.
