Our '05 Supercharged Mustang GT Premium is a real blast to drive! We loved the stock 300 H.P. Stang as it came, after we added the Vortech SQ polished Supercharger with the matching air-to-water intercooler she really came to life! The Supercharger with the intercooler is the answer to serious Stang 500 H.P. The Vortech is a real addition to the beauty of this car as well. We show it in the local CA. car shows and people always flock around to check it out.We take people out for a little test drive and they are always so surprized at the power this Stang will display."I'm still shaking" is not uncommon. In terms of bang for the buck, you can't beat the supercharged Stang!
