Dodge Viper Gen V WORLD RECORD!

As Dodge wound down production of its most unhinged sports car, D3 Performance Engineering decided the Viper deserved a proper send-off. Starting with a track-focused Gen V ACR, the shop added an F1X Procharger and a Nitrous Express kit to push the V10 past 900 horsepower, then took the car to the most demanding stretch of asphalt in the world to prove it. The result: D3 now holds the record for the quickest Gen V Viper on earth.

Every legendary car needs a proper send-off, and as Dodge began winding down production of its most unhinged sports car, a small group of owners and engineers weren’t content to let it go quietly. They wanted an argument settled, the kind only a stopwatch and the most demanding stretch of asphalt in the world could resolve. The car they built to do it doesn’t look like a typical record chaser, and the numbers behind it are almost absurd for a street-legal Viper. What exactly does it take to make the quickest Gen V Viper on the planet, and who actually pulled it off? The answer starts with a shop most casual fans have never heard of.

A Send-Off Built for the End of an Era

By the time Dodge confirmed it was ending Viper production for good, the car had already survived one cancellation and revival, stretching its history back to 1991 and spanning more than two decades of increasingly serious performance hardware. Rather than let that story fade out on a standard press release, a group of owners and engineers decided the Viper deserved a send-off that matched everything it had represented since the first Gen I cars shocked the industry with an aluminum V10 and almost no driver aids whatsoever. That meant taking a Viper somewhere it could prove a point definitively, not on a drag strip against a stopwatch alone, but against the most demanding stretch of asphalt most performance cars ever face. The project became less about marketing and more about settling an argument the Viper community had been having for years: just how far could a Gen V really go.

Who Is D3 Performance Engineering?

The build behind this record didn’t come from Dodge’s own SRT engineering team; it came from D3 Performance Engineering, a shop that has built a reputation specifically around pushing Dodge and SRT platforms past their factory limits. Rather than working from a clean sheet, D3 built its record car around a production Gen V Viper ACR, modifying the factory chassis and drivetrain rather than starting from scratch, a common approach among serious aftermarket shops that lets a build retain its factory-engineered strengths while adding the power and support hardware needed for extreme performance. That approach paid off directly, since D3 now holds the record for the quickest Gen V Viper in the world, a title earned through a combination of forced induction, nitrous, and careful chassis work rather than a factory-backed program. For a platform with as devoted a following as the Viper, that kind of independent, enthusiast-driven achievement carries real weight within the community.

The F1X Procharger Setup Explained

At the heart of the build sits an F1X Procharger kit, a centrifugal supercharger setup that compresses intake air using a belt-driven impeller rather than relying on exhaust gas the way a turbocharger does. Centrifugal superchargers like the F1X deliver boost that builds progressively with engine RPM, avoiding the lag associated with large turbochargers while still scaling to genuinely serious power levels on the right engine. Bolted to the Viper’s naturally aspirated 8.4-liter V10, an engine that already made substantial power in stock form, the F1X kit fundamentally transforms the platform’s output ceiling. Procharger’s F1X is among the largest centrifugal units the company offers, typically reserved for builds chasing four-digit horsepower rather than modest street-friendly power bumps, which signals from the outset that this Viper was never intended to be a mild, daily-driven upgrade but a genuine record-chasing machine built around a specific, aggressive performance target.

Adding Nitrous to an Already Boosted V10

Most builds stop at a single method of forced induction, but D3 layered a Nitrous Express kit on top of the Procharger setup, giving the car two independent ways to add power on demand. Nitrous oxide works by supplying extra oxygen to the combustion process, allowing more fuel to be burned and more power to be produced in short bursts, which pairs well with a centrifugal supercharger’s progressive boost curve by filling in power during the moments a nitrous system can deliver the biggest advantage. Combining boost and nitrous on the same engine requires careful tuning to avoid detonation, since both systems are adding cylinder pressure simultaneously, but done correctly it lets a build access power levels that either system alone would struggle to reach safely. That layered approach is a big part of why this Viper’s output climbed to genuinely record-setting territory rather than settling for an impressive but ordinary power figure.

North of 900 Horsepower: What That Means for a Viper

A stock Gen V Viper’s naturally aspirated 8.4-liter V10 already made serious factory power, with the track-focused ACR trim rated among the strongest versions of that generation. D3’s F1X Procharger and Nitrous Express combination pushes that same basic architecture to around 900-plus horsepower, a jump that fundamentally changes what the car is capable of at the strip and on a road course alike. That kind of power increase on a car still built around its original chassis and suspension hardware demands serious supporting modifications, stronger drivetrain components, upgraded cooling, and a fuel system capable of feeding an engine making nearly double its factory output. Getting there without sacrificing reliability or driveability is the real engineering challenge, since raw horsepower numbers are relatively easy to chase but keeping a V10 alive and consistent at that power level, run after run, is what actually separates a record-holding build from a one-time dyno stunt.

Setting the Record: Quickest Gen V Viper in the World

Holding the title of quickest Gen V Viper in the world means D3’s build has outrun every other example of that generation in a straight-line measurement, a distinction earned through the combined effect of the F1X Procharger, the Nitrous Express system, and the supporting chassis and drivetrain work needed to put over 900 horsepower to the ground consistently. Records like this matter within the Viper community specifically because Gen V cars, built from 2013 through 2017, represent the final and arguably most refined generation of the model before Dodge ended production entirely. Claiming the quickest example of that final generation carries symbolic weight beyond the raw numbers, positioning this specific build as a benchmark other Gen V owners and shops will spend years trying to beat. For a platform with no factory successor waiting in the wings, that kind of record becomes part of the permanent record of what the car was ultimately capable of.

Why the ACR Was the Right Starting Point

D3 built its record-setting Viper around an ACR, short for American Club Racer, the most track-focused trim Dodge offered on the Gen V platform. The ACR added an aggressive aerodynamics package, adjustable coilover suspension, and larger brakes compared to standard Viper trims, hardware aimed squarely at drivers who wanted to take their car to a road course rather than just a drag strip. Starting a record build from that foundation rather than a base Viper meant D3 inherited a chassis already sorted for serious lateral grip and high-speed stability before a single aftermarket part was added. That decision paid dividends once the car’s power output climbed past 900 horsepower, since a chassis with ACR-level aerodynamic downforce and suspension capability is far better equipped to handle that kind of power safely at speed than a standard Viper would be, particularly on demanding, technical road courses rather than a straight quarter mile.
