This 305 Cubic-Inch Supercharged Coyote Makes 1,400 HP! Find Out How

Ford built roughly 50 genuine Cobra Jet Mustangs in each limited run since reviving the nameplate in 2008 – and every one of them was designed to run a specific index number, not chase outright records. This car left that rulebook behind entirely, pulling 1,400 horsepower from just 305 cubic inches of supercharged Coyote. Read on for how the outlaw racing scene around cars like this got started, and why a small-block ended up making numbers Ford never advertised.

Fifty cars. That’s roughly how many genuine Cobra Jet Mustangs Ford Racing built in each limited run since reviving the nameplate in 2008 – which means the outlaw-class car in this shot, reportedly squeezing 1,400 horsepower from a mere 305 cubic inches, isn’t playing by the same rulebook as the factory cars it descended from. Ford’s modern Cobra Jets were built to run sub-10-second quarter miles straight out of the box, legal for NHRA Stock and Super Stock brackets under strict rules on weight, displacement, and equipment. But a growing number of owners have walked away from those index classes entirely, chasing raw numbers instead in a looser, faster corner of drag racing built just for cars like this. Where did that scene come from, and how does a small-block end up making numbers nobody at Ford ever advertised?

The Factory Program That Started It All

Ford Racing introduced the modern Cobra Jet Mustang in 2008 to mark the 40th anniversary of the original 1968 Cobra Jet, building 50-car batches equipped with a supercharged 5.4-liter engine, a stripped, NHRA-legal interior, and a curb weight in the neighborhood of 3,300 pounds – good for sub-10-second quarter miles out of the box. At the car’s 2008 debut at the NHRA finale in Pomona, Bob Tasca III and John Force each ran 10.8-second passes in cars they had never driven before, and a Hajek Motorsports-prepared Cobra Jet went on to win the 2009 NHRA Winternationals.

Why Some Owners Left the Index Classes Behind

Organizations like the National Mustang Racers Association (NMRA) give Cobra Jet owners a home outside NHRA’s index and handicap brackets, racing instead for the outright quickest time on the board. Once a car steps outside that stock rulebook, there’s no factory displacement or weight cap left to respect, which is exactly how a modern small-block like the one in this outlaw build ends up chasing numbers Ford never advertised on a window sticker.

305 Cubic Inches: A Coyote With a Small Twist

Ford’s 5.0-liter Coyote V8 displaces roughly 302 cubic inches in factory form, so a 305-cubic-inch version is essentially a stock-displacement Coyote with a modest overbore – the kind of change that comes with a fresh set of pistons during a full rebuild rather than a radical stroker crank. That is the remarkable part of this build. The engine is not a big-inch monster; it is a production-based, small-displacement V8 that relies on boost, fuel, and airflow rather than cubic inches to make its power.

How Five Liters Makes 1,400 Horsepower

Getting 1,400 horsepower out of five liters comes down to forcing enormous amounts of air through the engine. A large supercharger spinning at high boost, a fuel system capable of delivering the volume that much air demands, and an engine management system that keeps everything from detonating are the three pillars. The Coyote’s four-valve, dual-overhead-cam heads flow exceptionally well, which is why it has become one of the favorite platforms for high-boost drag builds. The result is a power-to-displacement ratio that would have been unthinkable when the original Cobra Jet was new.

Where the Outlaws Race

The outlaw Cobra Jet scene lives at NMRA events and similar Mustang-focused series, where classes are defined more by tire size, power adder, and chassis rules than by factory index numbers. That freedom is what attracts owners who bought a Cobra Jet as a turnkey drag car and then discovered they wanted more than the index classes allow. At those events, a Cobra Jet lines up against other heavily modified Mustangs, and the question is simply who gets to the stripe first.

The 1968 Original That Gave the Car Its Name

The name traces back to 1968, when Ford dropped the 428 Cobra Jet into the Mustang and sent a team of lightweight fastbacks to the NHRA Winternationals. Al Joniec drove one to the Super Stock Eliminator win that year, and the 428 Cobra Jet – famously advertised with a conservative horsepower rating that fooled nobody – became the engine that made the Mustang a serious drag racing threat. The 2008 revival was built explicitly to recreate that moment: a factory car that could show up at a national event and win.

Stock, Super Stock, and the Index Trap

NHRA Stock and Super Stock are index classes, meaning each car is assigned a class based on its factory weight and horsepower rating and then races against a set target time. A Cobra Jet in those classes is limited to factory-legal equipment and displacement, and winning comes from consistency and reaction time rather than outright speed. That structure is exactly what makes a factory Cobra Jet so valuable to serious bracket racers, and exactly what frustrates owners who want to see how fast the car can really go.

Clones, Bubbles, and the 50-Car Cadence

Because Ford builds only about 50 cars per run, demand has always outstripped supply, and that has created two side effects. Dozens of clone cars have been built to NHRA specifications by racers who could not get a factory car, and a surprising number of genuine Cobra Jets have been tucked away in climate-controlled storage as collectibles rather than raced. Roughly 300 cars had been produced by the time the outlaw scene took shape, a small enough number that the whereabouts of most of them is well known within the community.

From the 5.4 to the Coyote

The first-generation 2008 Cobra Jets used a supercharged 5.4-liter modular V8, a close relative of the engine in the Shelby GT500 of the same era. Later runs moved to the 5.0-liter Coyote as that engine became Ford’s performance mainstay, which is why a Coyote-based outlaw car like this one is a natural evolution rather than a departure. The Coyote’s aftermarket support is vastly deeper than the 5.4’s ever was, and its cylinder heads make it a far better foundation for the kind of boost that produces four-digit horsepower.

Detroit’s Factory Drag Car Arms Race

Ford’s revival of the Cobra Jet kicked off a factory drag-car arms race. Dodge answered with the Challenger Drag Pak, Chevrolet brought back the COPO name on a purpose-built Camaro, and all three manufacturers have kept updating their cars for NHRA competition ever since. That competition is good news for outlaw racers, too, because every new factory drag car brings better parts, better chassis engineering, and more owners willing to push beyond the index classes to find out what the hardware can really do.
