If you could get maximum performance safely why not?

You would need turbos designed to flow efficiently at that high an rpm, which I think would be difficult. For example, in an interview with an engineer for the ferrari 488 gtb said they limited the rpm to 8k because the turbos couldnt keep up and it would be spinning the motor more without making anymore power.

But dont get me wrong, if I could have a 9k TT Z I would rev to redline even if it doesnt make more power

There is a guy that spins an evo at 12k and makes god like power. Takes some deep pockets to make it work.

I guess he is running a humongous turbo and in order to keep it "spooled up" he needs to rev that high. And yes, deeeeeep pockets are needed since at those levels of rpm's there is something giving way all the time.
I remember the Mazda RX-7 when people where pushing the 9,500 rpm band and flywheels were coming of the vehicle thus injuring the drivers. But it can happen in any engine that spins that fast.

Geez, thats not cool

What's not cool? The flywheel severing the driver's feet and injuring others or revving that high?

I know what you meant.
