15k if you have a 2 piece E-shaft and center bearing. I doubt they'd be making power without a peripheral port but hey you could do it...
Most agree on 10.5K as the absolute max rpm for the standard single piece shaft and not severly lightened rotors. Getting a motor to make power that high might be a more difficult task than keeping the engine from wearing itself out from side housing collision.

It isn't safe to rev past 10,500 unless your clutch assembly is specifically rated for higher RPMs. The clutch assembly can come apart and the shrapnel can go through the floorboards and hurt/kill people in the vehicle
People who race usually invest in a scatter shield.
The redline is there for a reason. But, if you look at dyno tests from most cars, especially stock ones, you will see that the peak torque for a given tranny gear is reached before readline. Reving higher doesn't really serve a purpose. Go to my thread here and read about the formula to use to calculate the torque rear wheel for a known engine HP, tranny gear ratio, and rear diff. ratio. It's a bit long, but its worthwhile info.

boost on the way(GTU II)
YESSS ! carnage!!
my friend from PR said he saw a flywheel off a starlett(rotary) cut the legs off a guy and hit a house across the street and get stuck in the brick on the house. WILD!

BS meter is pegged on that one.... The flywheel doesn't have enough energy to cut through the bell housing, the floor pan, the people in the car, then the side of the car, and then go flying across the neighborhood and into a brick house, let alone stick in it.... They can blow up and explode like grenades when spun too fast but you're talking much much higher revs than have been mentioned here. if you want to talk urban legends go to the lounge.
The flywheel will not explode at 10.5K, nor will the E shaft break off. There is great truth in the redline advice for stock motors. I was assuming these wouldn't be stock ports because of the nature of the question. I've still got plenty of pull left past 7K. in fact I pull pretty damn hard at 7k. One high volume fuel pump later and I'll know when I actually run out of pull because I run out of gas flow while still pulling at 8100.
In all honesty my tranny is what I fear coming apart below 12K.
