What can the busa handle rpms

[birdwah]

i was thinking of getting the power commander ignition module you can extend rev limit i was wondering what a internally stock busa can handle? does anyone know?

handle as in the highest rpm? I've heard around 12K would be safe. Don't take my word for it though.

I've got the extended REV ecu on my bike, it added another 1k to the stock limiter. It is fine, i have only hit the limiter a few times at the track when the PSI on the airshifter gets a little low and it doesn't get all the way into second gear and stays in neutral. It has never given me any indication that it is "over-reving".

when my motor was stock it stopped pulling way before 12000 on the dyno.
