Rarely come close to red lining my manual trans 2021 LT-1 but the other day on a 2nd to third shift, I glanced down and realized I shifted at somewhere between 6500-7000 rpm. Didn't feel any stoppage of power. Is fuel cut off 7K?

6600 rpm, you should have felt the car lay down when your foot was to the floor and you hit 6600rpm

From data on the track my car redlines at 6530. I did money shift once from 3rd to 2nd and it went all the way a bit over 6900 though, no damage to the engine, just locked up my rear wheels.

Where you data logging? what your saying is if you hold your foot to the floor lets say in 2nd gear until the engine lays down, your data log says the engine is cutting off at 6530 rpm?

Yes data is logged, I even have it on video, here you go.

Timestamp - 4:53 - Redline @ 3rd gear
Timestamp - 6:25 - Moneyshift

RPM values on the lower left.

This is from a 2017, but the engine is the same and I'd be surprised if GM modified these tables in later model years. The rev limit is 6600 rpm, provided that the engine has run for a while and warmed up, and there is also an unconditional ("extreme") 6700 rpm cutoff.

Couple of things. Almost positive I wasn't flooring it. Maybe 80% throttle - which is a guess.

My car is a manual. Wondering if the rev limiter is intelligent enough to cut off a little later at part throttle since revs can rise at different rates. I realize the auto can hold a gear in manual mode but not so sure it would behave the same way as a manual.

I would assume if you were not at WOT, it could trigger fuel shut off a little early, or the ECM was allowing for WOT rates on how soon the engine would reach redline and since you were not at WOT your rpm climbed a little slower.
