One off over rev - does it mean anything?

[Rav_s]

So this morning, wasn't paying attention, music too loud etc etc, didn't realise until too late but revved upto about 8,000 (maybe slightly more) from standstill in first gear (manual 981 Cayman S). Yes I know I'm stupid. But I'm normally exceptionally careful with stuff like this (never redlined the car before). All I want to know is if I'm screwed come warranty renewal time (next March)?

Thanks

Relax! Hitting the rev limiter is fine (well maybe not from cold too often!). Overrevs happen on fluffed downshifts at high speed e.g 5th to 2nd.

I thought it was impossible to over rev the 981, or is that just the PDK?

Racing Porsche ... no problems they have a limiter ...... if you had been on track you would have hit it a few times ........ 5th to 2 nd is adifferent story even then that happens and again it depends whether on the gas or not at the time ....... and luck

Yup

Yup

You won't hurt a modern car by pressing the accelerator pedal - but it's easy to do with the gear lever! Which is one of the reasons why so many high performance cars no longer offer a manual transmission.

IIRC Porsche won't accept a car for "approved used" if more than 5 over-revs are logged in the ECU. (Again, that's counting real over-revs, not enthusiastic excursions to the rev limiter.)

I think Porsche counts hitting the limiter as an over-rev, which is pretty silly. If hitting the limiter damages the engine, the limiter is set too high!

The ECU records two different types of incident under separate codes,
1. Hitting the rev-limiter
2. A real over-rev; typically a fluffed manual downchange.
Only the latter are considered to be problematic.

I hate to see what my rev range 1 and 2 look like, given I sometimes get lazy when doing donuts and just lean on the limiter until I get bored.
