First DEMON Street Race vs. 2017 ZL1

A heavily built 2017 Camaro ZL1 — upper pulley, E85, methanol, custom headers — lined up against a Dodge Demon running nothing but pump gas and the factory tune. On paper, the built car had every advantage. Dodge’s from-the-factory drag weapon had other plans. The race has kept circulating for years, and the comment section still can’t agree on who really should have won. See how the numbers stack up.

A stock car isn’t supposed to win. That’s the whole premise of a street race grudge match — one side spends years and thousands of dollars chasing horsepower, and the other side just shows up in whatever rolled off the truck. When a heavily built 2017 Camaro ZL1 lined up against a bone-stock Dodge Demon, the smart money was on the car with the upper pulley, the E85, and the custom tune. The dumb money was on Dodge’s factory drag-strip weapon showing up to a knife fight with a rocket launcher. Only one of those bets paid off, and the result kept people arguing in the comments for years afterward.

A Built ZL1 With Nothing Held Back

The ZL1 in this matchup wasn’t stock by any measure. Its owner ran an upper pulley swapped down to 2.30 inches, tightening the belt ratio on the LT4’s factory supercharger to force more air through the 6.2-liter V8. A Vengeance Racing cold air intake fed it, Kooks 2-inch long-tube headers cleared the exhaust, and the car ran on a blend of E85 and methanol injection — a combination tuners lean on specifically because it lets them run more boost and more timing without detonation. Justune handled the tune, and Nitto 555r drag radials put the power down. On paper, this is a car built specifically to embarrass box-stock supercars, which made the outcome all the more interesting.

The Demon Showed Up Exactly As Dodge Built It

The Demon side of this race ran nothing — no bolt-ons, no tune, just pump gas and the factory calibration Dodge shipped from the factory. That’s remarkable considering what the factory calibration already includes: a 6.2-liter supercharged Hemi rated at 840 horsepower on 100-octane race fuel (808 on pump gas), a Torque Reserve system that pre-loads boost before launch, and a two-step launch control tuned specifically for drag radials. Dodge built the Demon to leave dealership lots and go straight to the strip, and this race is essentially what that engineering promise looks like when it’s tested against a car someone spent real money trying to beat it with.

Why the ZL1’s Recipe Should Have Been Enough

E85 and methanol injection aren’t cosmetic upgrades — together they’re one of the most effective ways to add real, reliable power to a factory supercharged engine. E85’s higher octane and additional cooling from methanol allow a tuner to run significantly more boost and advance timing further before the engine starts knocking, and a tightened supercharger pulley multiplies that effect by spinning the blower faster at every RPM. Combined with headers and a proper cold air intake, this is the exact formula that regularly pushes LT4-powered Camaros well past 700 rear-wheel horsepower. It’s the kind of build that beats stock Hellcats and Demons in a straight line — just not always the way the spec sheet suggests it should.

The Transmission Comment Nobody Expected

Viewers zeroed in on something beyond horsepower: the ZL1’s automatic transmission. One of the most upvoted comments on the video calls the “A10” — GM’s 10-speed automatic, co-developed with Ford and shared across the ZL1, Mustang GT500, and F-150 Raptor — “a god of transmissions,” and it’s not hyperbole. The 10L90 was engineered to shift under full throttle in single-digit milliseconds, keeping the engine in its powerband through every gear change instead of losing momentum the way older 6-speed automatics did. In a heads-up street race where reaction time and shift quality decide close margins, that transmission is doing as much work as anything under the hood.

What the Demon Gave Up to Be a Drag Strip Special

Dodge built only 3,300 Demons for the US market in the 2018 model year, and every one of them arrived stripped for the strip: no passenger seat, no rear seats, and a narrower front track achieved by pulling the sway bar entirely. It rode on genuine drag radials from the factory — a first for any production car — and needed 100-plus-octane race fuel to unlock its full 840-horsepower rating. Dodge even included a business card-sized certificate with each Demon acknowledging it wasn’t recommended for daily street use. That level of factory commitment to quarter-mile performance is exactly why a stock Demon can hang with cars that have thousands of dollars in supporting modifications.

Street Racing Grudge Matches as Their Own Genre

Videos like this one exist because grudge racing occupies a different space than sanctioned drag strip competition — there’s no class structure, no handicap, and no guarantee the “smart” build wins. What makes them compelling to watch is exactly the uncertainty on display here: a car with real, documented modifications against a car with a manufacturer’s warranty still intact. Comment sections on these videos tend to split cleanly between people defending the built car’s specs and people pointing out that stock horsepower numbers from the factory are frequently underrated to begin with — a debate this particular race did nothing to settle.

Where Both Cars Stand Today

Six-plus years after this race and both platforms have only grown in reputation. Demons regularly sell well above their original MSRP at auction, with clean, low-mile examples now commanding six figures — a remarkable trajectory for a car Dodge originally priced around 86,000. The sixth-generation ZL1, meanwhile, remains one of the last naturally aspirated-block, supercharged domestic platforms before GM shifted Camaro production away entirely, making built examples like this one a snapshot of a specific era of LS-based tuning that current Camaro owners can no longer replicate on a new car.

The Numbers That Actually Decided the Race

Strip away the debate over stock ratings versus real-world output, and the numbers on record still tell most of the story: a Demon at 840 horsepower and 770 lb-ft of torque, versus a ZL1 whose owner never published a dyno sheet in the video itself, leaving viewers to estimate output purely from the parts list. That asymmetry — one car with a certified factory number, one car with an educated guess built from a modification list — is part of why this matchup kept circulating years after it was filmed, drawing new viewers who each want to run their own math on who should have actually won, and why the argument in the comments has never fully settled.
