Because you need supporting mods to be able to do it. Without them you will have issues such as a broken crank or valve float. Stock motor = No go.

Going to 8400 or even 8500 is fine on the stock motor for limited duration but you run a higher risk of breaking something. 1slow370 has been running 8700rpm on a stock crank for thousands of miles but he is also dry sump.

Thanx for this. 9k is crazy cool but I'm not looking to break stuff. Wanting to shoot for 8200 with the stage 1 JWT cam and was planning on the nismo pump but now we have a real alternative.

I Thought he was running 8250 rpms? unless he up'd the rpms sometime after he sold the car?

He is only running 8,300 rpm on a stock crank with bmw m5 con rod bolts. Bottom end is oem besides those con bolts.

I guess he dropped it back down since I last rode in the car... It was retarded either way! The gears felt like they never ended... EVER!!!
