If changing gear most of the time at 6000 or 7000 rpms, will the clutch wear out quic
Does the clutch wear out quicker if changing gears at high rpms?
|
correct me if i'm wrong, but riding your clutch would wear them out faster.
but why are you shifting at 6K-7K all the time? besides using more gas, i don't see the need unless you're always driving at full tilt :) but i got to admit it is damn fun to wring out the engine to redline every so often....hehee ;) |
What do you mean by riding the clutch?
I dont slip the clutch, just change gears at high rpms because this car is just for the track or mountain twisties on Sunday mornings. In other words , its just a car for fun. |
Riding the clutch is driving with the clutch pedal partially depressed almost the entire time your driving.
|
I drive mine like that a lot, 69,000 on the clutch so far, no issues yet.
|
No no I dont ride the clutch , just revved to redline all the time.

Riding the clutch does two things;
1. If you drive with your foot partially depressed on the clutch pedal, it will engage the throw out bearing on the pressure plate and the throw out bearing will spin with the engine RPM causing premature wear. 2. From the time when the clutch disc touches the fly wheel until it's full engaged and spinning the same RPM's the disc is "slipping". The less time the disc slips the less wear on the disc. (I'm not advocating side stepping the clutch, that's a whole other story) To answer the original question, if your quick and smooth with your shifts you should be alright. Just a personal thought; There's an old saying that I live by, and being a mechanic all my life I can attest to it; Double the RPM, triple the wear. P.S. You like to rev it to the redline? Remember that the computer logs rev limiter and over rev's. My new Durametric scanning tool showed my '04 S was 0/0 on both counters. Good news for reselling and warranty work. |
If you are afraid of clutch wear there is one simple fix - don't use the clutch. That's right, I said, don't use the clutch. If you shift smoothly and slowly and put it back in gear at the exact rev-matched RPM you don't need a clutch.
Try it at low RPMs sometime. Pop it into neutral with your foot on the gas just a little. Then lot the RPMs drop for the next gear, rest your hand on the shifter and apply gentle pressure. It will drop right in. Now, I do not recommend doing this as a regular habit. But doing it a few times will give you a better feel for how the drivetrain wants to shift. Then shift like that but with the clutch and you should get very long clutch life. Regards, Alan |
Assuming you are using the clutch correctly, no worries.
Your engine is another matter. Keep redlining that baby and you will get a nice $12K surprise. Good luck. PS-Do a search here on blown engines. It may change your driving habits. Good luck. |

I've shifted mine above 7000 at full throttle at least a 1000 times by now (15 times yesterday). 69,000 and counting..... |

If you want to really refine your skills, learn to downshift without the clutch, a bit more of a challenge to do it smoothly. In terms of wear, the way I think of it is by the cost of the components. Brakes are cheaper than a clutch, and clutches are cheaper than a tranny. So, I use my brakes instead of engine braking, and use my clutch to minimize tranny wear. On my M3 and 914, I've always been in the habit of double-clutching all downshifts, it's only marginally slower and saves a bit of synchro wear, while giving you a jerk-free gearchange. |
I've been hearing this advice since the 70s, and have a long history of fixing teenager's transmissions after they have tried this.
If you wish not to use the clutch, install a tranny without synchros. |

If you can't redline your Porsche, what good is it? I've regularly redlined all the BMW's and Porsche's I've owned as that's what they were designed to do. I've banged the rev limiter on all my cars more times than I could count - even our Toyota minivan! |
Another Paul that knows how to drive Porsches!!!!

Sorry, I have to chime in here...
Redline (max recommended RPM's) and rev limiters are in place for one reason and one reason only by the manufacturer. If you exceed them, permanent engine damage will result, period. So constant revving up to it- I'm sure isn't good. As I said in a past post, the on board diagnostics records all over-rev's and length of ignition interruptions (rev limiter). Big brother's recording you and if the dealer sees it while doing warranty work, forget about it! :eek: I guess you can rev minivans to redline all the time and nothing will harm them right? |
Chime heard, but I've been rebuilding motors since the 70s....
I agree about hitting the rev limiter during the warranty period, I try to shift just below it. |

Many manufacturers (including Porsche) do endurance testing on their motors under lab and track conditions where the engines are run at or near redline conditions, with WOT, for hours at a time. No owner would ever have the opporunity to subject their motor to such stress. The way I look at it is that if a motor cannot be operated at redline, then it isn't redline. If touching redline from time to time causes my motor to fail, then the motor's design and/or engineering is flawed, and if the manufacturer won't back up their product, then I won't buy from them again. |

Great quote there. :) |
