Muscle Mustangs & Fast Fords
2013 Ford Mustang GT - The Green Goblin
The inside scoop on an amazingly quick, street-legal 5.0 Coyote Mustang
You might be wondering just how Chicago-native Justin Cyrnek’s journey to owning one of the world’s quickest and fastest Coyote-powered street-legal Mustangs came to fruition.
It’s much like many other Mustang love affairs. You know, 16-year-old gets a first Fox-body because it’s the “cool” car to have in high school, and it blossomed from there.
By age 22, Justin had started a Chicago-based business specializing in used forklifts, aerial work platforms and other heavy equipment, and he also met his wife, Julie, who also happens to love Mustangs. And while his Mustang was important, the fun was sidelined for years as he focused his efforts on building a thriving business. Sadly, he took a hiatus from hot rods.
Then, in 2012, Justin dabbled in drag racing with his ’07 Shelby GT500, but that ride was ancient history in comparison to the technology of the new 5.0 that had been dominating the quarter-mile. It didn't take long for him to notice the super-quick Coyote cars flying down the track, setting record after record—especially the mean machines prepared by Evolution Performance.

Justin began researching the platform and saw a couple of shops sending their Coyote powered stallions down the 9-second quarter-mile slot with a simple supercharger swap and a few mods. He wanted to get in on the action, but could have never imagined what would lie ahead once he got his hands on a ’13 GT.
Fred Cook of Evolution Performance guided Justin from the beginning, and they became instant friends in the process. Gotta Have It Green was launched as a factory Mustang color in 2013. It’s a bold statement color that fits Justin’s personality perfectly. He ordered the brilliant metallic green, 5.0-powered ’13 Steed, aka The Green Goblin, and made a very expensive phone call to Evolution Performance to order a laundry list of go-fast parts.
Justin started with a goal of mid-9-second e.t.’s, while still maintaining mild street manners. But in the blink of an eye he was building an all-out road-worthy race car that was sure to be a winner. The initial sticker shock was followed by pure adrenaline and it was time to go really freaking fast.
The build started with a 2.9 Whipple and other supporting mods, a built Circle D 6R80 automatic six-speed transmission, full exhaust, and Steeda and FRPP suspension goodies—all powered by E85 with a matching fuel system.
The setup was finished off with a small dry-shot of nitrous to help cool the hot IATs coming from his supercharger. Jon Lund worked his tuning magic with SCT tuning software, and the Green Goblin put down 845 rwhp at the King of the Street competition in Bowling Green, Kentucky, in 2012. It’s safe to say that Justin and his mean green machine made some waves in the racing world after its KOTS appearance. The 2012 season ended on a high note for the Evolution crew and their new customer.
To say Justin was motivated to get even more power is a gross understatement. As he puts it, “I wanted the most badass Gotta Have It Green Mustang in the world.” Little did he know he would actually end up with one of the quickest street-legal Coyotes on the planet.
With winter closing in, the ideas started flowing, so Justin and TeamEvo focused their efforts on ditching the built factory transmission and opting for a super-lightweight TH400 automatic with a custom billet converter with a 3,800-rpm stall. Justin wouldn’t spill the info on the brand, but it won’t be long before people figure it out and follow suit on a setup that works as well as his.
Untested and straight off the trailer, the bar was set really high with the fastest pass we’ve heard of for a street-legal, ’11-and-newer, 5.0-liter, Four-Valve Mustang—8.46 at 163 mph
The next order of business was the rearend—they ultimately ended up with an Evolution Performance custom-fabricated 9-inch packed with Strange 40-spline, gun-drilled axles; a 3.70 rear gear ratio; and a spool. Evolution handled everything from the custom JRS Fabrication 10-point cage to the carbon-fiber driveshaft. Working around the clock for 30 days, Fred and his extremely knowledgeable tech, Chuck Wrzesniewski, took this project to the next level stopping at nothing to get it right. Justin wanted pure perfection and a show quality car in an all out race car, and he got just that.
Justin had the stock motor pulled and sent it off to Michael Rauscher of L&M Engines, the builder behind many record-setting ’11-and-newer Mustangs. Using the aluminum block and maintaining the 5.0-cube status and going with lower than factory 10:1 compression, the Green Goblin was going to be on a high-boost diet.
They kicked the 2.9 to the curb and went with a 4.0L Whipple twin-screw. Still, they weren’t pushing the limits of the new blower because they only needed about 20 psi to reach their goal. The internals of this L&M built powerhouse are impressive to say the least—decked out with the best parts money can buy, including custom Diamond pistons, Manley Pro Series I-beam rods, custom L&M cams, and Slawko ported heads and intake.
It was almost time to cut this Coyote loose after a few finishing modifications such as a Ford Racing throttle body, JLT Big Air 155mm cold-air intake, and American Racing Headers’ custom 2-inch long-tube headers. Again commissioning the tuning expertise of Jon Lund, the Evolution Performance boys eclipsed triple-digit dyno numbers, laying down 1,130 rwhp and 1,080 lb-ft of torque fueled by Sunoco E-85R.
And while green means go, you can’t go efficiently without the proper suspension. Dialing in a road-worthy car at this horsepower level can be a daunting task. It takes specialized parts and an understanding the physics involved in getting the power to the ground. With brands like Santhuff, Lamb, and Racecraft in the suspension chassis lineup, it was expensive, but a worthy investment.
Where the rubber meets the road, this green bad boy sits on Weld Magnum skinnies up front and Magnum bead-locked rear wheels covered in stiff sidewall 30x10.5-inch Hoosier drag “slick radials.” The suspension and tire combination has worked flawlessly for this high-horsepower thrill ride.
Untested and straight off the trailer, the bar was set really high with the fastest pass we’ve heard of for a street-legal, ’11-and-newer, 5.0-liter, Four-Valve Mustang—8.46 at 163 mph with a vision-blurring 1.26 60-foot in Norwalk, Ohio, at Summit Motorsports Park. Let’s not forget the car still weighs over 3,300 pounds with the driver.
Justin ran another 5.0 Shootout event in June 2013 and went head-to-head with the fastest Coyote cars in the country, ultimately bringing home the crown. “I can’t think of what I love about the car the most, but the workmanship is second to none and the entire car, from top to bottom, is show quality. It has a 7.95 in it with the 4.0 liter in its sleep,” Justin stated.
In 2014, NMRA is launching a Coyote Modified class and the Green Goblin will be rocking a smaller 2.8 Kenne Bell to meet with the class limitations on blower size. You might be wondering what he did with the 4.0 liter—he did what any sensible person would do and he put it on his wife’s new silver Coyote-powered 5.0 and went 8.70s with it. These guys are hardcore boost gangsters!
We haven’t seen the last of the eye-catching Mustang either. Justin and Fred are betting on a 7-second e.t. in the near future. As you can see, this corn-fed beast is ready to make some tire smoke.
When asked what he loved the most about his Mustang, Justin couldn’t think of any one thing, but said, “It’s green, it’s fast, and it’s cool!” We agree!
