The Ford Mustang Shelby GT500 has shown its prowess on the track many times, but with the car built to go around corners fast, that's not much of a surprise. What's also not a surprise is that tuners and drag racing aficionados have pushed it to its limits in a straight line - but what would you do if you had a 5.2-liter supercharged V8 developing 760 horsepower and 625 lb-ft of torque? Getting a GT500 into the nines on the strip is no big deal anymore, but like so many others, Palm Beach Dyno is obsessed with going even quicker. The tuner thus took its shop GT500 to the track to test a new tune, and the results are phenomenal.

Testing took place at Palm Beach International Raceway, the scene of many a quick quarter-mile time. Judging by the tuning house's name, it's safe to assume that this drag strip is conveniently located for revisions and testing and that rigorous testing has paid off - with a quarter-mile time of 9.304 seconds. That's very quick, but even more impressive is that this was achieved with a trap speed of 155 mph. If you watch the video or have been keeping up to date with Palm Beach Dyno's YouTube channel, you'll know that this is a big improvement - the last video posted shows the GT500 doing a 9.37 at 150 mph. In this game, millimetric improvements are a big cause for celebration.

The tuner isn't done yet either. Next up is an ice tank that should help with a higher exit speed, but more importantly, getting the GT500 to dip into the 9.2s. From what we can tell, this car has a carbon fiber hood and slicks, but because this is a development car, no power figures have been disclosed. As you may have already seen, the Track Pack option for this car can limit its ability in a straight line, but we can't help but wonder if the available carbon fiber wheels that you can spec the GT500 with would have helped a little more. One thing is for sure - an eight-second GT500 will definitely go even faster sometime this year.
