Hate to say it, but that car you raced wasn't a Super Snake. I've got an 06 Mustang, as well as a Camaro, (I don't discriminate with muscle cars) and have wasted quite a few hours getting to know Mustangs, before really getting into pro-touring. In the video you posted, the car looked like a regular GT with a Roush body kit, and maybe a blower, from the sound of it at the end. Unless he's got forged internals, I doubt he's putting down more than 450rwhp, which explains why you blew past him. Hey, he probably felt emasculated by that sinister looking 69 of yours and had to say something
BTW you really make wish I'd gotten brushed hoops and my forgeline ZX3s, the new wheels look killer
