V6 Mustang SMOKES a 720hp GT-R!!!

A base-looking V6 Mustang with three people on board, the air conditioning running, and a passenger whose only job is pushing the nitrous button just ran down a heavily tuned Nissan GT-R putting out roughly 720 horsepower. Limitless Performance’s 575-horsepower build, nicknamed “The WEIRD,” reportedly wasn’t even using its full nitrous shot on the pass. Commenters are calling it the ultimate sleeper, and arguing about what a six-cylinder Mustang beating a supercar really proves.

Picture this: three people in the car, the air conditioning running, and a passenger in the back seat whose entire job for the run is pressing a single button. That’s the scene inside a Mustang that, from the outside, looks like nothing more than a base six-cylinder pony car, no GT badge, no big wing, nothing to suggest it belongs anywhere near a drag strip. Limitless Performance built this one anyway, and what happens when it lines up against a heavily tuned Nissan GT-R putting down roughly 720 horsepower has racked up over two million views. The Mustang’s driver reportedly wasn’t even using the full nitrous shot on the pass that made this video famous. So how does an ordinary-looking V6 with a passenger whose only job is a button push end up humiliating a genuine 700-horsepower supercar?

A Six-Cylinder Called “The WEIRD” For A Reason

The car at the center of this video has a name almost as unusual as its performance: Limitless Performance nicknamed their build “The WEIRD…” and the moniker fits. Under the hood sits a 3.7-liter V6, the same base engine that came in six-cylinder Mustangs nobody looked at twice on a used car lot, built up to somewhere around 575 horsepower. That’s a staggering jump from the roughly 300 horsepower these engines shipped with from the factory, achieved through forced induction, a nitrous system, and the kind of fabrication work that turns an unassuming commuter engine into a genuine drag weapon. The body panels, by every account in the video and comments, remain stock-appearing, which is exactly the point: nothing about this Mustang’s exterior signals what’s happening under the hood, and that mismatch between looks and output is the entire foundation of the sleeper concept this build is chasing.

The Passenger Whose Only Job Is One Button

The detail that had viewers laughing hardest wasn’t the horsepower number, it was the back seat. One commenter admitted they lost it when they realized the passenger sitting behind the front seats had exactly one job: hitting the nitrous button on command. It’s a small detail that says a lot about how these grudge-race builds actually operate away from professionally staged drag strip runs with electronic activation systems. Someone has to physically trigger the nitrous shot at the right moment, and in this case that job went to a human being riding along for what was apparently a full three-person pass, air conditioning running the entire time. Commenters were quick to note the extra weight and drag that setup represents, three occupants plus climate control is not how anyone would build a car specifically to set a record, which only made the run against the GT-R more impressive to the people watching.

They Weren’t Even Using The Full Shot

Perhaps the most telling detail in the video’s description is that the Mustang wasn’t even running its full nitrous shot during the pass that beat the GT-R. That’s a meaningful admission, because it means the margin fans watched on screen wasn’t the car’s ceiling, it was a conservative pass that still got the job done. For a build already sitting around 575 horsepower from a six-cylinder platform, holding something in reserve suggests the team behind “The WEIRD” either wanted to protect the drivetrain for repeated runs or simply didn’t need to unleash everything to make their point. Either way, it reframes the whole matchup: a stock-bodied, three-person, air-conditioned V6 Mustang didn’t need to floor everything it had to put a genuinely quick, professionally tuned all-wheel-drive supercar behind it, and that gap between what the car showed and what it apparently still had left is exactly what keeps commenters replaying the clip.

One Fewer Turbo Than The Car It Just Beat

Commenters were careful to point out this wasn’t an apples-to-oranges fight in every sense, one viewer noted that both cars are technically running V6 engines, with the Mustang doing its work using one less turbocharger than the GT-R. Nissan’s GT-R has built its reputation since the R35 launched in 2007 around a twin-turbocharged 3.8-liter VR38DETT V6, and a tuned example putting down roughly 720 horsepower represents a serious, well-established platform with all-wheel-drive traction and a drivetrain engineered from the factory for exactly this kind of abuse. That the Mustang’s single-turbo, nitrous-assisted six-cylinder could run down a car with that pedigree and that power figure says less about the GT-R being weak and more about how far domestic V6 builds have progressed. It’s the kind of result that only lands as shocking because of the assumptions built into each car’s reputation, not because the GT-R underperformed.

Loud, Ugly, And Built To Win, The Sleeper Formula

Even the sound of the car became a talking point. One commenter observed that the Mustang seems to be running an open exhaust setup, noting it’s “best for performance, not for sound,” a trade-off familiar to anyone who has built a drag car and prioritized flow over refinement. Combined with the plain exterior, that unpolished, aggressive exhaust note reinforces exactly what another viewer called it: “the ultimate sleeper.” The sleeper tradition in muscle car culture goes back decades, built on the idea that the most satisfying wins come from cars nobody respects at a stoplight. A V6 Mustang carries almost none of the built-in credibility that a 5.0 GT badge or a Camaro SS emblem would bring to a lineup, which is exactly why watching one dispatch a 720-horsepower GT-R lands so differently than the same result from a car everyone already expected to be fast.

“Yeah, It’s Still A Mustang”, And That’s The Point

Not every reaction in the comments was celebratory, and the video’s own audience called that out directly. One commenter observed that as soon as a tuned GT-R gets beaten by a stock-bodied V6 Mustang, people instantly reach for excuses, pointing to remarks like “yeah, it’s still a Mustang” as if the badge should disqualify the result. The same commenter fired back that this was missing the point entirely, “that’s kind of the point,” they wrote, arguing that a six-cylinder Mustang embarrassing a genuine supercar is precisely what makes the video worth watching. That tension, between GT-R loyalists explaining away the loss and Mustang fans savoring it, is part of what has driven the video’s engagement past two million views. Even the joking aside about “523 GT-R fans and owners” disliking the video captures how personally invested both fanbases are in a single quarter-mile pass.

What Fans Want Built Next

The video also sparked a wish list in the comments rather than just a reaction. One viewer said they’d like to see more worked-up V6 Mustang and Camaro builds pushed to this level, specifically name-checking the 5.0-liter Mustang GT and the Camaro ZL1 as platforms that deserve the same treatment. It’s a fair ask, both of those cars already carry serious performance reputations out of the factory, with the ZL1’s supercharged LT4 delivering over 600 horsepower stock and the 5.0 GT’s Coyote V8 serving as the backbone of an enormous aftermarket. But there’s something specific about starting from the humble V6 Mustang, a car most enthusiasts write off as the base rental-fleet option, that makes builds like “The WEIRD” resonate differently. It proves the sleeper formula doesn’t require a performance-oriented starting point, just the right combination of boost, nitrous, and a driver willing to leave the badges alone.
