Randy Koon - 2013 Shelby GT500 Super Snake

One of the baddest Mustangs you can buy is the Shelby GT500 Super Snake, and the 2013 example is obviously one of the most powerful ever. For Randy Koon, this is not his first Super Snake. He also owns a fully modded ’08 Super Snake convertible. You’d have to agree he is a fortunate fellow.

“When I heard of the ’13 Shelby GT500, it offered many of the same improvements—compression ratio, Ford GT cams, so on—that I had completed on my ’08 SS,” Randy said. “I ordered the car in May 2012, and I was hoping for delivery in July in time for Mustang Week 2012, but I missed it by one week.”

Obviously, Randy had plenty of sunny days to break the car in prior to this year’s Mustang Week and the Battle at the Beach. Even better, it gave Randy time to ship the car off to Las Vegas for a Super Snake conversion, which he picked up in December 2012. Along with the standard SS package, he also added an ARH exhaust and a 10-percent-overdriven crank damper from Innovators West. As a result, Randy had a pretty stout car to enter into the battle.

“In all actuality, I went into the event knowing that I didn’t have a chance to win it,” Randy said. “I had even told my buddy that there would be some crazy twin-turbo car making 1,200 rwhp that would win it.”

As it turned out, there was such a crazy car, entered by Ryan Tutor, but Randy’s bolt-on Super Snake showed quite well in this crowd of stout ’Stangs. After drawing the second slot in the running order, his Super Super Snake laid down over 784 hp at the feet to take the fourth spot.

“I think the extreme heat and humidity played a major role in everybody’s expectations for output,” Randy said. “I know for fact my Super Snake did far better when it was tuned at Shelby’s Las Vegas facility. The atmosphere difference between here and there is like night and day, and the dyno numbers reflected that at the challenge.”

Tristan Coggins - 1988 Mustang LX

We were truly excited to have a potent Fox in the mix for the Battle at the Beach. Representing the old-school ’Stangs in style was Tristan Coggins’ ’88 LX coupe. He’s been building this car up since he bought it in 2011, and last year it picked up the turbo kit it runs today, but atop a stock-block 331ci stroker. Just months after Mustang Week 2012, the stock block split in half. Tristan was able to salvage the rotating assembly and transfer it to a Dart block.

“Ever since I got the new engine together, I have been driving it around town and 30 miles to work on nice days,” Tristan said. “I’m still waiting to install the Wolfe Race Craft rollcage and some larger front brakes. Hopefully, I’ll be able to get some track time in then.”

Tristan’s turbo Fox actually fared well, outdoing several newer Mustangs to take the fifth spot at the Battle. His car put down over 704 hp at the wheels despite drawing the unlucky last spot in the running order, meaning his car was run during the midday heat. Unfortunately his car also had the lone mechanical failure in our group of contestants.

“I didn’t have any tuning problems, but I had some extra weight in the trunk due to some tools I had in case of any problems,” Tristan explained. “And I was sitting in the passenger seat, which resulted in the car sitting too low and the tire catching the fender well, ruining my brand-new ET Street.”
