ChrisFix sets out to settle a garage argument that never seems to end: does a performance exhaust actually make more horsepower, or does it just sound like it does? He tears into a full cat-back install, high-flow cats, an X-pipe, and straight pipes, and puts the results on a dyno before and after. Along the way, one unscripted moment involving his own mother became more famous than the horsepower numbers themselves.
Fifty years of muscle car culture have never agreed on what makes a car ‘hot’ – raw factory horsepower, a numbers-matching restoration, or a modern resto-mod build. This deep red machine parked outside a garage door raises that same debate all over again. Is it the stance, the sound, or the story behind it that decides the verdict? See where this one lands and decide for yourself.
The 440 Six Barrel gave the 1970 Road Runner three two-barrel carburetors, 390 horsepower, 490 lb-ft of torque, and a Dana 60 rear axle — the same hardware the mid-1969 A12 package introduced with its pinned-down fiberglass hood and hubcap-less steel wheels. Just 1,815 were built for 1970, and it ran the quarter mile in the low thirteens. Read on for why it was the smarter buy than a Hemi.
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.
The Vipers gathered at this 2015 show were living on borrowed time, even if nobody knew the exact date yet. This piece looks at what made the final-generation Viper, 645 horsepower, naturally aspirated, six-speed manual, the angriest version of a car that never once used a turbo or supercharger in 26 years of production.
Modern muscle cars like the Hellcat twins hit numbers the original 1960s and 1970s era never touched, but they get there through supercharging and computer control instead of big cubic inches and low compression. Here’s a closer look at how Detroit’s horsepower war came back in the 2010s, and what changed in the engineering between the original muscle car boom and its modern revival.
An 1100-horsepower AWD Nissan GT-R should win this fight before it even starts — thats the whole point of all-wheel drive at a standing start. But this Nth Moto-built Dodge Viper, running an estimated 1700 horsepower through an old-school H-pattern manual and nothing but 18-inch street tires, had other plans during a night of TX2K18 street racing. The 50-to-180-mph numbers alone are worth the watch. See how a rear-wheel-drive holdout took down the AWD favorites.
A $239,400 McLaren MP4-12C and its 616 horsepower twin-turbo V8 take on a stock, all-original 1970 Chevelle SS 396 that once sold for around $3,200. The video calls it a joke comparison, but the Chevelle runs a genuinely respectable 13.7 seconds and the comments turned it into something more interesting than a punchline. One viewer did the math: the McLaren has already lost well over half its sticker price while the Chevelle is worth many times what it cost new. Watch the run, then read why almost nobody in the comments picked the McLaren.
This CasualRacing compilation strings together some of the most expensive mistakes made behind the wheel of a 707-horsepower Dodge Hellcat. From a bystander offering body shop directions before the dust even settles to a dealership salesman sprinting clear of a demo drive gone wrong, these are the moments Hellcat owners hope never make it online. Watch to see just how fast that much power can turn a green light into a very public lesson.
A Cadillac CTS-V owner ripped out the factory supercharger and replaced it with a 106 millimeter turbo, roughly tripling the car’s horsepower and putting it into low 7-second quarter mile territory. This run was the setup’s maiden voyage, bugs and all, and the video does not hide that. Comments have zeroed in on the turbo’s jet-engine presence and the fact that the interior is still mostly intact despite the radical power increase. Watch the run and see what 1,600-plus horsepower looks like in a car that still has a back seat.
Most 1970 Dodge Challengers spend their lives on quiet Saturday cruise nights, never once seeing triple-digit speeds. This one runs the German Autobahn regularly, camera and speedo mounted for anyone brave enough to watch the needle climb. Viewers keep coming back to a very specific complaint about this car in the comments, and once you hear the engine screaming near 140 mph, you’ll understand exactly why.
A 1967 Barracuda wearing ‘AAR’ badging is borrowing a name that wouldn’t exist as a real Plymouth package for three more years. That contradiction is exactly what makes this custom build interesting – a first-year redesigned Barracuda dressed up as a legend that hadn’t been built yet. Here’s what the real 1967 Barracuda offered from the factory, and where the AAR name actually came from.
A 1970 Dodge Charger R/T nicknamed “Street Shaker” showed up at Detroit Autorama 2013 with a spoiler most ’70 Chargers never wore from the factory — and somehow made it look right. Commenters argued color combinations, debated originality, and one self-described Chevy fan admitted the Mopar won him over. See what tipped the scale.
