The S197 Mustang GT is 3550 lbs. The supercharger adds a minimum of 100lbs to the car. That makes it 3650 lbs. The GTO is 3725lbs. That makes the difference 175 lbs from a stock GT to a GTO and 75 lbs for a supercharged GT to a GTO. Man if you can't get these details correct, what else are you off on.

The Roush Mustang stage 3 supercharged is 410 or 415 hp the next step up is the 427. I raced a 427 last week with my LT4 Vette. The guy was running 13.3. My LT4 was running about a half a tenth faster. I'd say a GTO would be about a tenth faster than my LT4 was, maybe a tenth and a half. The guy was a better than average driver too, he was cutting high 1.9's in the 60' area and was within a tenth on the tree. That's not a poorly driven car.

I've also seen road tests of the Saleen and Roush cars and in one that Car & Driver did, they compared the car to the GTO and it was a slight advantage to the GTO, but they didn't test the cars back to back so call it a drivers race.

The Ford factory supercharger isn't as agressive as the Roush and Saleen cars are. It can be modified to be more aggressive, but it isn't out of the box. If the Ford factory car is stock from the dealer trim he's going to get beat by a stock GTO.
