Hi, I have an S2 exige (standard 190 BHP)…tonight I accidentially went to 3rd from 4th, whilst the engine was already at about 6,000 rpm. As soon as 3rd engaged, the redline/ change-up light came on and god knows what the revs were. Anyway, then the revs started bouncing up and down around 5 to 6,000 rpm, which I assume was the rev limiter? I tried the car through to the power cam again afterwards and all seems ok. I just wondered if I might have caused any damage?
Thanks for your thoughts.

Boothy should be able to help with this question this is so his territory!
If it’s still running ok you should be fine …
Speed at 6000rpm in 4th, should be the same as about 7000rpm in 3rd? Was just trying to think how many revs are reduced when going from 3rd to 4th at the same speed and not 100% sure but i think it reduces by about 1000rpm so you should be fine.
As long as the engine was up to temperature it should have no problem dropping down to third.
Thanks guys. I drove the car to work this morning and all seems well. I’m not sure exactly how high the revs went, but high enough for the change-up light to immediately illuminate. I assumed the bouncing between 5 or 6,000 rpm (ish) straight after was the rev limiter. It was a bit of a messy moment really, which started with someone right up my er backside!!! Anyway I think the engine was at temperature, so it should be ok.
Thanks again.
Did the engine reach it’s operating temperature?
Otherwise it go’s on at much lower rev’s.
The rev limiter is there to help not to overrun the engine.
Q.
I’m always hitting it on track…no time to change and/or a benchmark to see how many times I bounce off it before braking again…

You should be ok, if you have no issues after, the 2 normal failures if the 2ZZ is “buzzed” are
Oil pump failure
Valves contancting pistons
If it is still running ok, I’d say you are fine.

Wondered why your lap times were getting longer… 
Seriously, nice driving mate… saw the red mist come down just afer you let the Porky past!
I DO like the 2nd cam noise of the NA Toyo too!
Thanks guys. The engine did reach normal operating temperature and it seems to run fine. I’ll be a little more careful with my gear changes next time…

As alluded to by Ade, Rev limiter protection only works when changing up - it’s fooked if you buzz the engine. I have heard of a TypeR being buzzed to 27000rpm (6th to 2nd instead of 4th), before exploding (ECU recorded the incident).
Holy crap 27,000rpm…
Crickey…even Boothy would be proud of that!

Is that what you call “flat” out?
What’s this I keep reading about Boothy and ‘flat out’ ?

Lol Cheers mate, we got to get Spa meet on one day!
Yeah, crap engine…it could only manage it the once!
Mr Pesky,
Do you think my engine is still ok then? (as I was changing down at the time?!)
Thanks,

PS Drove fine at lunchtime, through the power cam in 2nd and 3rd

Sorry, if my earlier post alarmed you - I was just pointing out when the rev limiter has no effect.
Your car sounds to be perfectly okay…
BUT don’t do it again!
