The peaceful sounds of a babbling brook are suddenly overridden with an even more glorious sound — a supercharged Mustang approaching. This is no ordinary Mustang. Ryan’s yellow 2015 Mustang GT sports more than 930 horsepower at the wheels, which is well over 1,000 at the crank. What must driving such a car be like?
It doesn’t drive like it has 1,000 horsepower. — Ben Thorn, Gears and Gasoline
“This car I am driving right now like a completely normal car. It doesn’t drive like it has 1,000 horsepower. In fact, with the (exhaust) cutouts closed, if you stayed below 4,000 rpm I would never know that it had 1,000 horsepower or that it was anything besides a Mustang GT with an exhaust,” Ben Thorn from Gears and Gasoline said with a hint of surprise.
While Ryan’s Mustang is impressive, there is one downside to burning corn to support that kind of power. “The only thing stopping me from daily’ing it is E85 availability. It gets 8 miles per gallon, to be honest, so I could only go back and forth to work three or four times before I have to fill up,” Ryan confessed.

• ProCharger D-1SC supercharger
• McLeod RXT clutch
• Shelby GT350 intake manifold
Obviously, Ben hasn’t spent much time around power-adder Mustangs from the modern era, as their combination of driveability and performance potential are un matched. However, most projects of this caliber start out the same way.
“Everyone starts of with, ‘Well, I’m just going to do an intake, exhaust, and tune.’ That way it sounds really cool and makes a little more power than stock,” Ryan, the owner of this car, explained. “Then you go, ‘Well, a supercharger’s not that expensive…”
Boost Is Better
Ah, yes, the slippery slope of horsepower addiction. If bolt-ons are fun, wouldn’t a power adder be more fun? The answer is undoubtedly ‘yes!’ Even though Ryan’s car started out strong with baselines of 400 horsepower and 390 lb-ft of torque at the wheels, the siren’s song of centrifugal boost was too loud to ignore.
On a built Coyote, a ProCharger D-1SC is the gift that keeps on giving. From just above 3,000 it starts pulling strong and doesn’t quit until the tach needle hits the redline.
“I always wanted a supercharged car, so we budgeted for it,” Ryan said. “So we went with the ProCharger and rebuilt the engine with forged internals, but kept a lot of the stock parts. They are actually pretty stout.”
To maximize that built engine, he chose a ProCharger D-1SC, which is designed to support 925 horsepower, 1,400 cfm, and up to 32 pounds of boost.
People are really surprised at how fast it is considering that it does not look special. — Ryan, car owner
The result of this revamped combo is certainly stout, as the car put down over 932 horsepower and 694 lb-ft of torque at the rear wheels. On the half mile, this stock-appearing S550 puts that power to good use as it ran over 172 mph in the half mile.
“People are really surprised at how fast it is considering that it does not look special,” Ryan added.
The subtle, comfortable package that carries that performance definitely puts this one in the sleeper category, which is why it probably surprised the video host even though he knew how much power the car made.
“Rarely do we drive any car that feels so well suited to its modifications, especially one with well over double factory horsepower,” says Gears and Gasoline. “Ryan’s Mustang, intended for both weekend blasts and half-mile racing, has a fully built motor, equipped with a ProCharger centrifugal supercharger. The 930whp it produces hits you like a ton of butter, and feels like what a thousand horsepower might feel like from the factory.”
“That was very controllable. The car kinda started to get a little squirrelly. It feels like it’s moving left and right a little bit, but it’s not like the back end is trying to come out on you,” Ben said after a power run through the gears with traction control on. “I can’t believe that a car like this will do that on stock suspension and on Michelin Pilot Super Sports. It’s totally insane. That’s fantastic. The days when you had to sacrifice your interior, you’re A/C and all that kind of stuff are gone.”
