HELP! accidental overev!

[nfaj]

Idk my exact speed when it happened. I was paying attention to the road more than the speedo. Regardless of how fast I was going i saw >8500 on the tach :/

Option 1:
Pull the motor, pull the heads, inspect everything.

Option 2:
Do nothing.

Not sure what you are looking for us to tell you? Whether the car seems fine or is acting up, the above are pretty much your only two options regardless. If it hit 8500rpm under minimal load, I wouldn't be too concerned about it personally. Only you know things like if you let the clutch all the way out, how fast you were actually going, etc.

I'm pretty sure the clutch was out all the way for a sec or half a sec max. I was at 7400 when I accidentally down shifted into 3rd. Would a compression/leak down do anything for me as far has piston head damage and bent valves?
Man I'm paranoid as fuck

If everything feels fine, you're probably fine. Aside from the balance of the internals, the only issue I can see that prevents higher revs is stuff like valve float causing the piston to contact the valves. Not sure if this is even an issue on our cars or not.

In short, if everything seems fine, you're probably okay. Not much you can do to inspect without a LOT of work that's probably not worth is. ECU most likely already recorded the over-rev as well.

Lastly, I suggest you learn pronated/neutral/supinated hand position shifting instead of "fake gated shifting." You'll be much less likely to miss a shift that way.

@aznatama Thanks for the advice! Is there anyway to reset the Ecu to erase that over rev log? Disconnect battery maybe?

I don't know about the 86's ECU, or if it even has an overrev counter. However, in cars that DO have the counter, no, it is not generally resettable unless hooked up to a computer. I guess I wasn't completely clear, but I meant that IF the ecu has a counter, it'll likely been tripped already.

First post here It happened to me two days ago on the track. It was my first trackday, second turn of the day. The main straight finishes almost exactly at the end of 4th gear. I'm very used to downshift to decelerate on street, and therefore I've downshifted to 3rd when I was barely starting to brake. Revvs jumped over 8.5k rpms. I've changed asap to neutral, but a good second passed before I've corrected.
The car seems to be fine, I've babied it for 2 full laps, listening to sounds etc... Since the car was pulling fine I've pushed and I've attained my record lap just 5 minutes after the miss shift.
It's however 2 nights that I can't sleep: I really love my car and I'm worried it will result in a major engine failure sooner or later.

You would be that guy to post this. Is the cat driveable? Check the block.

Usually, not always but usually if you are going to cause damage in an over rev it happens right away. With a one off situation I would not worry since the car is running fine. There is really nothing you can do now since if you did cause an issue th damage is already done. Very unlikely you did though so go take a nap and stop obsessing about it.

Give up on life, the car is totalled. You should just give it to me.

I get it bro I'm just being paranoid since I was going atleast 110+ on 4th that would've easily been over 9k in 3rd .

I gotta say, if you were doing 110 on an interstate, I really don't give a damn what kind of shape your car is in now.

I've just seen too much asshattery on the interstates lately to have much pity.

At this point you've voided any notion that anyone should care what you did. 110 in unreasonably fast to be going on a public road.
