Overrevved and Misshifted - Will I know if i damaged valvetrain right away?
so unfortunately tonight messing around , I wanted to test a full redline pull. so my second run from a second gear pull I hit the rev limiter a LOT sooner than I'm used to (car just got protuned, literally my first day testing its limits on an open road). the car bounced off the rev limiter a couple times, I tried insta upshifting but I think it locked me out of 3rd because of the RPMs bouncing off or maybe I got nervous from hitting the rev limiter. pretty nervous now, no smoke, no weird sounds. did multiple pulls tonight with a friend's mk7 gti and car is running fine.
my question is, if I damaged valves or anything in the valve train, would I know instantly on the car or could I have caused damage that's not going to surface for a few thousand miles?
I am going to change the oil since I wanted to after the dyno session and will check back in... thanks to any and all who respond

So let me get this straight.
You just bounced off the limiter in 2nd.
You didn't force the car into 1st while redlining in 2nd.
Correct?
You're fine. Nothing is damaged. The limiter is there to keep you from over revving the engine.
When you have time, visit a local autocross event and watch cars bounce off their limiter for seconds at a time .

but if I jammed into first at 70 mph wouldn't I be on the side of the road and not driving full capacity an hour later? No smoke or idle sounds or anything

If you have an OBD 2 reader, see if you have P0219 - Engine Overspeed Condition stored in the ECU. The ECU triggers and permanently stores that code when you go over 8043 rpm.
It's probably in your head though.

okay will be checking soon, this could trigger even without a CEL?

I can't imagine being able to jam it into first at that speed though. It locks you out pretty good. I mean I never tried to force it in, but I know first gear lockout is definitely hard to bypass. I think if you bounced off the limiter in second and managed to downshift into first, you would have a lot of parts on the ground under the car, scattered all over the road.

Agreed with everyone here - OP sounds like me after my first (and only) launch of the car.
The OPs car was probably thankful to get a dose of WOT, everything is fine.

so I used one of those ****ty pocket obd 2 readers and no codes came back, I feel like if its there tho id need to use one of those nicer scanners.
yeah i was thinking the same thing, and on top of that I just can't imagine shifting from 2nd to 1st like I know its possible but that shift is like riding a bike, 2nd to 3rd is so natural.
hopefully lol

If you really don't trust your reader (by the sounds of it you are good), just get a tactrix port for ecuflash, open ecu flash, set it to canbus 2.0 and scan for codes. But to be honest, it's probably not going to report back if your $10 piece of junk didn't.
Then you are setup for the future (or I guess you are tuned, so the present?)
