based on that wheelie and what i know about turbo drag cars. im willing to be it was closer to 50 psi. i have a friend with a supra drag car and he runs 48 psi on his drag setup, 35 on street setup. the simple fact he wheelies and actually lets out of it and then gets back in and still wheelies shows he has to have close to or above 1500 hp. typically once a driver lets out of a wheelie even a little bit, it is extremely hard to keep that wheelie up like that. its a rarity. i'd say atleast 1300-1500 hp needed for that.
