chances with what? That you'll have a blowout at 90mph and crash? That you'll get arrested? That you'll die? If you aren't knowledgeable about suvs or their driving characteristics, then you shouldn't be an idiot and risk your life for this. You shouldn't do this ever.
BTW, "top of the line X5" means nothing. Year, engine?

Sorry for being tough on you, but it's better than you ending up in the ER or in jail.
If you really want to know, look up 0-60 times on google.
(I am assuming that you are talking about street racing. Please, correct me if I am wrong, though, and I will gladly retract my comments.)
