Default Exceeded RPM redline in 2nd gear...did i goof anything up?

I was entering an on ramp last night and had it in 2nd gear. The music was kinda loud and it was late on a friday night and i ended up exceeding the redline. I hit bettween 64 & 6500 rpm. I think the redline on '00 RSs is 6200, right. I noticed this when i felt my engine skipping, i guess it was the pistons giving way. Anyway, i immediately let off thr gas. It only lasted for about 2 seconds(the skipping part), at the most. It seems to be driving fine today and it drove fine immediately afterwards. Is there anything i permanately may have messed up?


thanks for continued help.

I don't THINK so... Thats what the rev limiter is for to prevent you from ****ing up something... I think if there was any damage it would prolly be with the trannie if any. Ive done this a few times didnt seem to hurt anything, just don't make a habbit out of it.

Yep the "skipping" you felt was the rev limiter doing its job. It's there just for this purpose, to prevent you from over-reving the engine and doing damage. So you didn't break anything.
You can, however, over-rev on a misplaced downshift. The ECU can't do anything about that because it's a mechanical condition, so if you go from 5th to 4th and get 2nd by mistake you can break things.

edit- Scotty said it in fewer words while I was still typing-

I thought the rev limiter still worked if you double-clutch downshift. Or does it simply work in shifting up the gears?

The rev limiter works by cutting fuel if you accelerate beyond the permissible RPM. It can't do anything if you downshift into the wrong (too low) gear in which case the drivetrain will be pulling the engine and forcing it to spin at a speed determined by the gear ratios. If this happens you can turn the key off and it will still be over-reving, so the ECU has no say in the matter. The only thing that may save you here is to step on the clutch immediately.
