I'd take boost over n2o anyday. A blown Mustang with bolt-ons is a lethal street combo. I'd try to steer you in the direction of a Procharger or Vortech but that's not what we're here to talk about. A tb would help esp if the car is supercharged. Accufab makes nice pieces. Headers would also give him a gain but on those dohc motors the installs are very time consuming. Another nice piece for a supercharged applications is Anderson Power Pipes, it's like a true CAI. Whatever you do, he has to have more hp because he doesn't have headers and has more weight because of the vert. ~Brian
