A stock Dodge Challenger Hellcat and a stock Dodge Viper lined up at the WannaGoFast half-mile event at Sulphur Springs Airport, Texas, with barely over a mile per hour separating their best trap speeds. Peter Dunn’s footage reignited the long-running debate over supercharged V8 power versus the Viper’s lighter, more aerodynamic chassis. See which car actually posted the higher number across multiple runs.
Trap speed doesn’t lie, and when two of Dodge’s most extreme production cars lined up at a Texas airstrip, the gap between them came down to barely over a mile an hour. One car relies on a supercharger whining loud enough to hear over the engine itself; the other leans on a ten-cylinder engine and a chassis built from the start around aerodynamics. Both are stock. Both are capable of speeds that would get a driver arrested on almost any public road in the country. So which one actually walked away with the higher number when the runs were finished?
Why This Wasn’t a Quarter-Mile Race
This matchup didn’t happen on a typical eighth- or quarter-mile track — it ran at the WannaGoFast half-mile event at Sulphur Springs Airport in Texas, a format built specifically for cars capable of triple-digit trap speeds with enough runway to actually get there. Peter Dunn’s video captured a stock Challenger Hellcat against a stock Dodge Viper across multiple passes, with the results measured in trap speed rather than elapsed time. That distinction matters: a half-mile shootout rewards top-end pull and aerodynamic efficiency in ways a quarter-mile race simply can’t capture, which makes this a genuinely different test of these two cars than the more common short-track comparisons.

The Numbers That Decided It
By the end of the runs, the Hellcat’s best pass reached 156.3586 mph, edging out the Viper’s best of 155.2795 mph — a margin of a little over one mile per hour after both cars had every opportunity across multiple attempts. That’s close enough that driver execution, launch conditions, and even wind on a given pass could plausibly account for the difference, rather than a decisive mechanical advantage for either car. For two vehicles built on such different philosophies — one supercharged V8, one naturally aspirated V10 — ending up separated by that little at half-mile trap speed says something about how competitive Dodge’s SRT lineup has stayed with its halo Viper.
Two Completely Different Ways to Build a Fast Dodge
The Hellcat’s approach is brute force: a supercharged 6.2-liter V8 pushing well over 700 horsepower through a chassis that started life as a mainstream Challenger coupe. The Viper takes the opposite route, built from the ground up as a lightweight, aerodynamically focused sports car around an 8.4-liter V10 making roughly the mid-600s in horsepower depending on model year, prioritizing chassis balance over outright power. Commenters on the video were quick to bring up exactly this contrast, debating whether raw supercharged torque or a lighter, slipperier package matters more once speeds climb into half-mile-run territory.
The Viper Owner Who Jumped Into the Comments
One commenter, who described owning a 2010 Viper equipped with an 8.4-liter V10, Belanger headers and exhaust, and a K&N filter making around 650 horsepower, claimed he’d beaten a Hellcat in a real-world highway pull — a claim that immediately shifted the discussion from this specific video’s result to the broader Hellcat-versus-Viper debate that’s followed Dodge enthusiasts for years. That kind of firsthand account, even lightly modified, adds real weight to the argument that the Viper’s lighter curb weight and superior aerodynamics can offset the Hellcat’s power advantage in exactly the conditions this half-mile format tests.
Why Weight and Aero Mattered More Here Than Usual
Multiple viewers pointed out that the Viper’s chassis was designed from day one with weight distribution and aerodynamic drag in mind, while the Hellcat is fundamentally a heavier, more practical coupe that happens to carry an enormous supercharged engine. At a standing quarter-mile, raw power often wins outright; stretched to a half mile, drag and weight start eating into whatever advantage that power provided in the first few seconds. That’s likely why the margin between these two cars was so much tighter here than it might have been over a shorter distance, and why the debate in the comments focused so heavily on chassis fundamentals rather than horsepower figures alone.
The Ongoing Argument Over Dodge’s Best Modern Performance Car
This video reignited a long-running argument among commenters over which car deserves the title of the greatest production Dodge or SRT model since the muscle car era of the 1970s. Some sided with the Viper for its purity as a driver’s car and its motorsport pedigree; others backed the Hellcat for democratizing genuinely shocking performance in a car that can still be optioned as a comfortable daily driver. Neither side fully won the argument in the comments, which is part of why videos like this one keep drawing engagement — the debate itself has become as much a draw as the actual trap speeds. Both camps can point to results from this exact video to back up their case, which is exactly why the argument never seems to actually resolve itself no matter how many times these two cars line up.
What a Half-Mile Format Reveals That Drag Strips Don’t
Standard quarter-mile drag racing rewards launch technique and low-end torque delivery, but it doesn’t give a car much room to show what happens once it’s already moving fast and still accelerating. The half-mile format used at Sulphur Springs Airport forces both cars to keep pulling well past the point where a typical drag race would already be over, which is exactly why trap speed rather than elapsed time became the headline number here. For enthusiasts trying to understand how the Hellcat and Viper actually compare at speeds most drivers never experience, that distinction is the whole point of the event, and it’s part of why WannaGoFast events keep drawing serious owners willing to put stock cars on the line.
Why This Matchup Still Gets Attention Years Later
Both the Challenger Hellcat and the Dodge Viper occupy a strange, overlapping space in Dodge’s history — one a modern factory hot rod built for accessibility, the other a low-volume sports car built for purists, both capable of speeds that would have been unthinkable from Detroit a generation earlier. A half-mile shootout this close, decided by barely a mile per hour, keeps both camps engaged because neither side gets a clean, easy win to point to. That’s exactly why a video like this, built around a straightforward trap-speed comparison, keeps generating debate well after the actual event ended.

Viper will be lighter and quicker off the mark
Viper
Hell Cat
Put them on a track. People with actual driving skill don’t give a shit about drag racing.
Try and focus on the content of THIS video.
Nah. If they are going to use a fuckin TRACK car to drag race a one trick pony, then they themselves aren’t concentrating on it.
oh my god found the first one in the crowd
Robert; forming complete sentences > you.
Any Tesla?
Haha yeah put a base model s out there
The Viper, because it has a V-10
What does that have to do with anything lol
Put that Viper against the demon
Love them both
Love those vipers
One car for the family and the other for sporting around. Both unique! I did expect the viper to win.
If the quarter I’d say hellcat but it being half mile that put the viper where it come to life
Probably not considering the hellcat has a higher top speed.. but the first corner its getting passed lol
Randy Tibbs, Joe Fajardo, Eddie Pikulin
Viper on the track. Both exceptional machines.
Viper is more aerodynamic
Man its like everyone behind the wheel of a hellcat doesnt know how to launch it lol
viber
V10 vs. V8 ? not a fair line up
Driver, gear ratio, launch, and weight. All factor in.
Who cares both dodges.
Ill take either
