GR86 I may have done something stupid

[dimwit97]

Gday all i may have done something stupid, I was out on a nice road and downshifted a bit too aggressively and went from 5th to second instead of 4th! The engine sounded really high pitched like 14000rpm or something. The wheels locked up a little but it was alright in the end. I always thought that doing something like this would blow my engine but the car seems fine! Still drives great. But will my engine blow up the next time i drive it??

Pretty sure that if you'd properly money-shifted the engine would have been gubbed almost immediately - the 'tracksters' amongst us may be able to confirm? As for will it blow up next time; suppose that depends on your shifting.
When I was doing Driving Instruction I had quite a few 5th to 2nd engine brake moments. I told my students to try and avoid pulling the stick out of 5th too hard, giving it more of a 'flick' out, as it will naturally spring back to its home position between 3rd and 4th, whereupon you can nudge it down to 4th and will have avoided jumping past the gate into 2nd. Egg sucking lesson for Granny completed for today. I'll get my coat ...

EDIT, actually, simpler: What speed were you going when you went into 2nd? If below 60 you're likely fine.

Probably rear wheel locking is the noise you heard.

This is a good point, 2nd redlines at 59MPH or something, and OP said he was on a "nice road", which suggests not motorway/DC< so unless he was being very naughty, it's probably not over-revved by much.

A downshift to 4th would suggest it was at least below 100mph too.

Edit: just guessing, obviously I've never driven it past 70

It was on an empty straight road I was downshifting for a corner that would have ended me up in the medium to high revs in forth gear the rear wheels definitely locked up..

If you've had no ill effects since then you've probably got away with it. Only concern might be that the event will be logged in the ECU, so if you ever have to go to the dealer for engine issues they might be able to use it to get out of warranty claims.
