M-3 BMW differential

I have a BMW M-3 independent suspension rear end in my Backdraft. Engine is a 418 stroker pushing approximately 500hp. No, I haven't had it on a dyno yet. My question is, how much hp will the M-3 handle? Since I've not had it dynoed, I don't really have an accurate figure on the hp or torque. Kind of thinking I'd like to take the BDR to the drag strip but don't want to tear up the rear end.
