Robby Miller Keeps Taking His Mustang Game Up A Notch, And He's Not Done Yet
Horse Sense: Robby would like to thank his dad for sharing with him his passion for cars and always telling him to respect the car, whether he was out playin' around or working on it. "Yes, Dad, I still use jackstands," Robby says. "Special thanks to my mom for letting me keep that passion as a teenager," he adds. "To my wife and kids, you are the light of my life."
The challenge with Mustangs is staying interested with just one car. That's why you see or hear of people owning several at a time or going through Mustangs like regular people change underwear. It's a challenge to stick with just one Mustang for any length of time. We buy one, get used to the power, then up the power, then get bored with that power.
Eventually, we get bored with the whole car, and the hunt for something new begins. We've all been there. We either trade the existing Mustang for the next one, which is immensely popular, or-for the fortunate few-another Mustang is added to the foray to quench the thirst for new power.
Robby Miller is one of the fortunate few. His existing Fox, although a wicked whip in its own right, couldn't hold him back from thirsting after Terminator power.
Let's back up and find out how Robby got to this point. Like most of us, Robby's dad was guilty of bringing him and his sister up to love Mustangs. Dad instilled in them the importance of tight seat belts with his own '65 Mustang coupe. He would make sure the two were buckled in tight, and then launch the Mustang's 289 at full song. Every dad should be so cool.
Since that first launch, Robby's been hooked. When Robby hit 16, he drove several classic Mustangs in the hope of following in his dad's footsteps, but none were safe or reliable enough for a first car. Making a slight concession, Robby ended up with his uncle's '69 Mercury Cougar. No, it wasn't a Mustang, but in Robby's mind, it was old, it had a Windsor and a black vinyl interior, and "it would one-wheel peel like no one's business," he says.
That's good enough for us. "My friends and I kept the used-tire stores in business," Robby adds.
The Cougar was about all Robby could muster while working at a grocery store and going to school. It wasn't until after college that Robby's dad co-signed on a loan for a five-speed '87 GT. "It was everything I wanted and had read about," Robby says.
Robby hung on to the GT for several years, even selling it and then buying it back. It was his wedding car when he and high-school sweetheart Sonia were married. "It was our getaway car during the wedding. Shaving cream, toilet paper, and Coke cans tied to the GT wing," Robby tells us. The '87 was just the start of his Fox craze, which continues to this day with his '91 coupe and latest '81 T-top coupe, Four-Valve conversion.
However, one Mustang that really caught his eye was the Mystichrome '04 Cobra. Of course, it caught every Mustang fan's eye when it came out. The '96 Mystic Cobra was cool, but the Mystichrome's added visual effect only added fuel to the fire. The Mystichrome Cobra was an instant legend that still resides at the top of many a Mustang owners' wish list.
"I will never forget the first Mystichrome Cobra I saw," Robby says. "I was in love." However, a new house was on the horizon, along with Robby and Sonia's first child, which meant the Mystichrome's sticker might as well have been $1,000,000. Robby didn't even bother talking to Sonia about the car-he knew it was out of reach. He made a promise to himself that if he ever grew out of the Fox Mustang, a Mystichrome Cobra is the one he wanted to own.
Life kept going and Robby continued to play with Fox Mustangs, but he had reached a point where he wanted to add a new Mustang to the stable. Accordingly, he looked at '03-'04 Cobras, but the cars had maintained resale value so he settled on a '06 GT. "It was great," Robby says. "Ford hit the nail on the head," he added.
About this time, Robby met Donnie Salem, owner of Boosted Performance [(704) 896-3339] in Mooresville, North Carolina, and former King of the Street competitor. Robby knew of Donnie from reading about him in 5.0&SF, but Robby also found out Donnie was a pretty nice guy, too. That personality trait made it easy for Robby to send his new S197 to Donnie's for a Vortech S-Trim supercharger install. Robby enjoyed the 465 hp at the wheels, but also knew that was close to the limit of a stock bottom end Three-Valve.
You probably know what happened next. Realizing the Three-Valve's limitations, Robby got to thinking. Of course, Donnie was helping to throw Robby over the edge on going for a Terminator, but Robby needed little encouragement. The search was on for an '03-'04 Cobra, but an '04 with that special color was Robby's top choice. Unfortunately, he wasn't able to find a reasonably priced Mystichrome, but he was able to find a Sonic Blue example, to which Donnie added a Whipple 2.3-liter supercharger, 60-lb/hr injectors, a new clutch, and other supporting equipment. The result was 601 hp and 598 lb-ft of torque.
"Needless to say, I had never felt anything like it," Robby says. "A 500hp Fox is awesome, but this thing had torque that would spin Third gear at will." As a result, the S197 went down the road. "Suddenly, I knew what all the fuss was about with these cars," Robby adds.
Once again, time kept going, and Robby's friends knew he was always on the lookout for another Mustang, especially a good deal. One day before leaving the office, Robby gave the "Terminator-Buy/Sell" section on SVTperformance.com a refresh. "What I saw would seem like a dream coming true," Robby says. He had to hit the refresh button again to make sure it was for real. The new ad stated, "2004 Mystichrome KB Cobra, 43K, one owner, garage kept."
Robby couldn't even type he was so excited. In an instant his memory shot back to the first time he saw a Mystichrome Cobra. "By the next day, I had the deposit sent while trying to ward off many others who were also after the car," he says. Luckily for Robby, he was first in line. Was it fate? Robby thinks so. Whatever it was, he finally had his car.
As the ad stated, the Mystichrome already featured a Kenne Bell 2.6H supercharger, which had been installed by Modular Powerhouse when they were still just outside of Atlanta. However, the Mystichrome had an appointment with Boosted Performance for many of its current upgrades. Donnie performed some maintenance on the car, and Robby does note that a Kenne Bell Mammoth 2.8 purchased for another customer's car was tempting, but in the end, it was decided to stick with the 2.6H and upgrade everything around it to maximize its output. Robby's Mystichrome makes 615 hp and 698 lb-ft of torque at the feet.
To say Robby is happy with his Mystichrome would be an understatement. Every time he rolls through the gears, he's taken back to his Sunday afternoon rides in his dad's '65 Mustang. "I can only hope that my kids, Titus and Tessa, will take with them a part of history like I have," Robby says. "And yes, they love the smell of tire smoke." Sounds like Robby might've found the Mustang that could keep him from saying next. Maybe ...
