Default REV LIMITER OR MONEY SHIFT?? Help I can’t sleep

Laying in bed reliving the idiot move I pulled earlier today. Desperate for answers. Brand new Porsche owner. 2018 touring. drove manual my whole life. 67 camaro rebuild. 2014 z28. Audis jeeps yadayada.I can drive I thought.

3 days into my dream car I smack it into 2nd from 3rd at like 5500 rpms. I did this intentionally because I’m a moron and thought I still had plenty of room at 9000 rpm redline.. still getting used to this type of performance. Anyway jesus himself spoke to me through a disgusting rev Limit sound like a bro from Temecula revving his dirt bike in neutral. IT WAS AWFUL. Flys up to I think 9000+ I didn’t really have a moment to look down the sound scared me so bad. It was all a blur of regret.

here’s my question. Could I have money shifted this? Yes of course it’s possible but if I heard the rev limiter than I’m assuming a money shift wouldn’t have allowed for a rev limit because the momentum( if that was the cause) wouldn’t of allowed it to bounce the Rpms like it did. Anyway- what do I do. Don’t shame me. Thanks.

Not clear what you experienced, but 5500 in 3rd down to second is fine

My quick math says you were traveling around 68 mph at 5,500 in 3rd which is safe for 2nd (max around 80 mph)

My estimate at 5500rpm in 3rd would be around 80-85mph. 2nd gear max is 78mph per thread below, you may have gone over rev limiter. That being said, you may also not have damaged the engine.

Don't ever shift into 2nd if you're going 81mph or faster, 3rd if you're going 111mph or faster, or 4th if you're going 141mph or faster

I don't think the number from that thread are quite accurate...

Here is from factory (have to convert from kph to mph) - looks like 5,500 in 3rd is 68 mph which is safe in 2nd:

130kph is 80.1 mph for max speed in 2nd. Per chart, 5500rpm in 3rd looks like about 7700rpm in 2nd at 110kph

Btw, there is no good reason to try to cut it close. There is no good reason to shift so that you end up at redline in the next lower gear...

You should get a readout from the dealer and know what happened instead of guessing or asking others to guess with you. The results may, or may not, also impact resale. Many here who say no problem may have a different take if contemplating a purchase with documented high level over revs even if the engine is deemed “fine”.

Read out from the dealer will only give assurance of issue or no issue.

Resale value doesn't matter at this point as the action has been done and if OP enjoys the car then he won't care about resale.
