being the idiot that I am I think I hit the redline fuel cut-off the other day, took my eyes off the rev counter briefly while overtaking in 2nd. Someone please tell me that these engines are built to take occasional abuse from complete morons like me, it definitely won't happen again. There doesn't seem to have been any ill effects. It seemed to me that the car just momentarily lost power, but then carried on as usual. I suppose it could've been any number of things but the most likely scenario is I red-lined it. Am I the only idiot out there? [&:]

Hitting the redline going UP the rev-range is not a problem.
As you found, the rev-limiter cuts in and prevented over-revving.
However hitting the rev-limit by mis-changing DOWN (e.g. going from 5th to 2nd instead of 4th [
] ) is a problem - the rev-limiter can obviously do nothing about it and damage can result.
The OPC will interrogate the memory in the control module at each service, and all over-revs are logged. The first is not a problem, but the second can be - if you have a warranty claim they may be taken into consideration (big brother IS watching! [8|])
So in your case - don't worry about it, you will be fine. But do be careful on downchanges! []

That's no problem. On track days it happens all the time. In fact, if you are not redlining your Porsche, occasionally, some people would say that you are not be using it properly.
What you mustn't do, though, is miss a gear under hard acceleration (ie go from 2nd to 1st or 4th to 3rd). That will over-rev the engine, beyond the rev-limiter's capabilities, and will potentially damage the engine. And, the diagnostics will probably record it! So, don't expect Porsche to pay for any resulting damage.

so? do it all the time these cars are made for it. [8D]
Jut to add, that you should never redline the engine until everything (especially the oil), has reached their correct operating temperatures.
And, these days, there is a widely held opinion amongst some engine builders, that engines don't need to be 'run in'. They actually benefit from high revs in their early life. It is certainly accepted that engines that have not been regularly operated throughout their rev range may not be developing their full bhp.

As usual, great advice from all. Thanks, I'll sleep better now. It unlikely I'll screw up a down-change but obviously something to watch out for. I'm usually very careful about revs, but do deliberately come close to the red on occasions, it's part of the fun hearing that awesome sound. I'm also an exponent of never revving a car above 30% revs until at full temperature, I've taken care not to do this with all my cars, not just the Boxster. It does crack me up when I'm with someone who starts a cold car and then immediately drives flat out, I think most people I know do it.
