TT Mustang SCREAMS on Dyno – Nearly 1400hp!

This twin-turbo Coyote Mustang rolled onto the dyno at Dynoedge running a modified Hellion turbo kit, reworked specifically to shorten intercooler piping and cut turbo lag, and posted a run that pushed toward nearly 1,400 horsepower at 26 psi of boost. Commenters zeroed in on the exhaust note as much as the numbers, calling it one of the best-sounding Coyotes they’d heard on a dyno. Watch the full pull to see exactly what a shortened-piping Hellion setup can do to a factory 5.0.

There’s a moment on every dyno pull where the number on the screen either matches what the engine sounds like, or it doesn’t. When this twin-turbo Mustang rolled onto the rollers at a shop called Dynoedge, the exhaust note alone had commenters calling it the best Coyote sound ever before a single horsepower figure appeared. What came next put the car in a category most V8 Mustangs never reach, using a turbo setup that had been quietly reworked to solve a problem most builders never bother fixing. The full pull is worth watching before you find out exactly how far this one went.

The Hellion Kit Doing the Heavy Lifting

This Mustang runs a Hellion Turbo twin-turbo kit on a Coyote V8, the same 5.0-liter architecture Ford has used across S550 and S650 Mustangs, and it’s part of a wave of Hellion-equipped Coyotes that the channel 1320video has documented making increasingly serious numbers. According to the video’s description, this build pushed nearly 1,400 horsepower at 26 psi of boost, a figure that puts it well ahead of most turbo Coyote builds running similar hardware, and squarely into territory usually reserved for purpose-built drag cars rather than street-driven Mustangs.

Solving the Lag Problem Most Builders Ignore

What separates this particular kit from a typical Hellion install is the intercooler piping. The description notes the setup was modified to shorten the intercooler routing specifically to cut down turbo lag, a detail that matters enormously on a street car, where a twin-turbo setup that takes a beat too long to spool can feel undriveable in daily traffic. Reducing that piping length is a small mechanical change with an outsized effect on how usable nearly 1,400 horsepower actually is outside of a straight-line pull.

Why Commenters Kept Coming Back to the Sound

Multiple viewers singled out the exhaust note specifically, with one calling it hands down the very best Coyote sound ever and asking directly about the cam and exhaust combination responsible for it. That’s a notable reaction for a turbocharged build: forced induction typically mutes the kind of raspy, high-revving character naturally aspirated Coyotes are known for, but this setup apparently kept enough of that voice to stand out even on a dyno.

Dynoedge and the Shop Behind the Pull

The pull took place at Dynoedge, a shop 1320video has featured repeatedly alongside Hellion-built cars, and one commenter noted the shop and turbo kit combination has delivered strong results before, calling it a win again. That repeat pairing suggests a working relationship between the tuning shop and Hellion’s hardware that’s produced more than one headline-grabbing dyno number on this specific engine platform.

How This Stacks Up Against LS Swaps

One comment jabbed at a builder named Kyle, noting the car didn’t need an LSX swap to be great, a pointed reference to the long-running debate in the Mustang community over whether staying with the factory Coyote or swapping in a Chevrolet LS platform is the smarter path to big horsepower. A twin-turbo Coyote pulling nearly 1,400 horsepower on 26 psi is a strong argument for the former, especially for owners who want to keep the car’s factory identity intact.

What a Hellion Kit Costs Compared to Building Custom

Off-the-shelf turbo kits like Hellion’s Coyote system exist precisely because building a comparable custom twin-turbo setup from scratch, sourcing individual turbos, manifolds, intercoolers, and tuning software separately, costs significantly more in both parts and labor. For builders chasing four-digit horsepower without an unlimited budget, a well-sorted kit with known-good piping geometry, like the shortened intercooler routing on this car, offers a proven starting point rather than a season of trial and error.

The Role of Tuning in Getting There Safely

Pushing a factory Coyote block to nearly 1,400 horsepower isn’t just a matter of bolting on turbos and boost; it requires a tune capable of managing fuel delivery, ignition timing, and boost curves precisely enough to avoid detonation at 26 psi. Shops like Dynoedge specialize in exactly that kind of calibration work, and the clean, controlled dyno pull shown here, rather than a shaky, misfire-riddled one, is as much a testament to the tuning as it is to the hardware itself.

Where the Coyote Platform Goes From Here

Ford’s Coyote V8 has proven remarkably capable of absorbing forced induction without needing a full bottom-end rebuild, and builds like this one continue to push the ceiling of what the factory block can reliably handle. As more shops document runs like this nearly 1,400-horsepower pull, they’re collectively mapping out just how far a stock-bottom-end Coyote can go before something has to give, information that matters for every builder considering a similar turbo kit.

How This Pull Compares to Other Documented Hellion Coyote Builds

1320video has captured several Hellion-equipped Coyote Mustangs on the dyno over the years, and the numbers on this particular pull, pushing toward nearly 1,400 horsepower at 26 psi, rank among the higher figures the channel has documented on this specific combination of turbo kit and engine platform. Comparing pulls across multiple videos from the same channel gives a rough benchmark for what a well-tuned Hellion Coyote can realistically achieve versus what is simply optimistic marketing from a kit manufacturer, and this run lands solidly on the high end of that range rather than looking like an outlier or a one-off fluke. For builders researching whether a Hellion kit can genuinely deliver four-digit horsepower on pump-adjacent fuel, having multiple independently filmed pulls from the same shop and similar hardware combinations is far more useful than a single unverified number, and it is part of why content like this carries real weight within the turbo Mustang community specifically. It also raises the practical question of what a car like this actually does at the track rather than just on rollers, since a dyno pull, however impressive, only tells part of the story about how a car launches, spools boost, and holds power through an entire quarter-mile pass under real load rather than a controlled, stationary environment where wheel speed and cooling conditions are far more forgiving than an actual race.
