We Bought a GT500: Inside Hypermotive's New Shop Car — And Why We're Putting It on the Dyno Instead of a Pedestal
It's an idea we'd been kicking around for a while: pick up a 2020–2022 Shelby GT500.
Partly because a car like that belongs in front of a shop like ours. But mostly because the S550 GT500 — the Predator-powered, DCT-equipped, 760-horsepower version — is finished. Ford built it for three model years and moved on. Whatever wears the GT500 badge in the future, it will not be this car. That window is closed, and cars like this don't get cheaper once everyone figures that out.
So we went looking. And what we found was better than we expected.
First, Why This Car Is Special
The S550 GT500 was a genuine first for Ford, and it's worth understanding why before we start bolting things to it.
The 5.2L "Predator." A supercharged, cross-plane crank 5.2 — not the flat-plane Voodoo from the GT350. That's a meaningful distinction. Ford took the displacement and the architecture and built something entirely different with it: an engine designed from the start to live under boost and make serious power. From the factory it's 760 horsepower, and at the time that was the most powerful street-legal engine Ford had ever put in a production car.
The 2.65L TVS supercharger, sitting in the valley, fed by a dual-pump fuel system right out of the box. Ford didn't build this thing with the bare minimum of supporting hardware. They over-engineered it — which is exactly why it responds so well to upgrades.
The Tremec 7-speed DCT. This is the part people either love or argue about online, and we'll say it plainly: there is something absolutely special about this transmission. It shifts faster and harder than any manual, it's brutally consistent, and it changed what a Mustang could do at a drag strip.
And here's what's new and genuinely exciting: TCM tuning is now available. For years the DCT was a sealed box — fantastic, but exactly as Ford left it. Now we can get into shift points, shift pressure, and shift behavior and tailor the transmission to how the car is actually being used. For a shop that tunes for a living, that's a whole new dimension to work in.
The Car We Found
A 2022 GT500 in Dark Matter Gray — Carbon Fiber Track Pack — with 10,000 miles.
That's about as good as it gets. The right year, the right color, the most desirable package, and the mileage of a car that was clearly enjoyed carefully rather than hidden away.
Three weeks later, it looks a little different.
What We've Already Added
We didn't ease into this one. Here's where the car sits now, grouped by what each piece is actually doing:
Air and boost
- VMP Apex Predator supercharger upgrade lid
- VMP upgraded intercooler — sized to fill out the larger lid
- VMP 108mm billet throttle body
- SPE carbon fiber cold air intake
- VMP 2.8" pulley and a VMP 2.6" pulley (more on this below)
- Whipple billet belt tensioner
Fuel
- Injector Dynamics ID1050x injectors
- VMP billet fuel rails
Exhaust
- Fabhouse 304 stainless lead pipes
Cooling and drivetrain
- SPE DCT cooler line kit
- Radium radiator expansion tank
- Fathouse Performance supercharger reservoir
Brakes
- Hawk yellow ceramic brake pads
Engine bay
- Fathouse Performance Predator radiator cover and billet radiator brackets
Notice how much of that list is airflow and cooling rather than peak-power hardware. That's deliberate. The Predator doesn't need to be convinced to make power — it needs to be allowed to breathe, and kept cool enough to keep making it.
Where the Numbers Are Right Now
We've gotten real dyno time on this car in a short window. Here's exactly where it stands:
| Configuration | Result |
|---|---|
| 93 octane — 2.8" pulley, upgraded intercooler + supercharger lid, stock exhaust | 830 RWHP |
| E85 — 2.8" pulley, upgraded intercooler + supercharger lid, stock exhaust, upgraded throttle body | 890 RWHP |
Two things worth pulling out of that table.
830 RWHP on pump gas with the stock exhaust still bolted to the car. No headers, no cat-back, nothing cut. Just a better lid, a better intercooler, a smaller pulley and a proper tune. That's the Predator telling you how much it had left in it.
E85 was worth roughly 60 RWHP. That's the entire argument for ethanol in one line — more boost, more timing, a cooler charge, and a safer tune while making more power. (The upgraded throttle body went on for that pull as well.)
What's Next
Back on the dyno to test the new Fabhouse lead pipes on the 2.8" pulley and E85 — so we isolate exactly what the exhaust is worth instead of guessing at it.
Then the pulley swap to the 2.6". More boost, same combination, and clean before-and-after data on both changes rather than one big jump with three variables buried in it.
After that? Honestly, we haven't decided how deep we're going on this car. And we're comfortable saying that out loud.
Why We're Actually Doing This
Here's the real reason this car is sitting at our shop.
Our main goal is tuning development. Every pull we make, every pulley we swap, every configuration we log is data that goes straight into how we tune customer GT500s. When someone brings us their car, we want to already know what that combination does — where it makes power, where it heat soaks, where the knock threshold actually is, and how the DCT behaves when you lean on it.
That's the whole point: so what we hand our customers is the safest, most dependable version of powerful. Not a guess. Not a calibration borrowed from a car we've never driven. Real numbers from a car we own, abuse, and are willing to break on our own dime instead of yours.
It's a lot easier to be conservative in the right places when you already know exactly where the edges are.
One Last Thing: The Wheels
The Carbon Fiber Track Pack wheels are spectacular. They're also carbon fiber, they're an expensive option, and we have no interest in finding a pothole with them.
So we've already got a set of BC Forged wheels on order. The carbon wheels get preserved; the forged wheels get driven, dyno'd, and parked outside. That's the kind of decision that feels obvious right up until you own the car and start doing the math on what one curb costs.
Follow Along
We'll keep posting results as they come in — lead pipes, the 2.6" pulley, and whatever we talk ourselves into next.
If you're looking for GT500 tuning, parts, or a complete installation package, don't hesitate to reach out. We've got the car, the dyno, and now the data — and we'd rather put all three to work on yours.
