the engine starts losing power well before 9000 rpms in stock form, and the engine stays well within the vtec power band in each gear when shifted ahead of 9000 rpm so unless you have some big cams I don't see the need to go 9200. If you can make power right to 9000+ rpms with your engine then go for it, otherwise I don't see the benefit.

It’s not very clear some people state that the f20c redline is 9200 and some say it’s 9000

I'm curious - where are you getting this? It's been over a decade, but I'd have bet serious money my ap1 freely revved past 9k ... commonly accepted wisdom around here used to be approx 9,200 and change for fuel cutoff.
