Edmunds Corvette Stingray dyno pull

Edmunds has gotten a crack at the 2014 Chevrolet Corvette Stingray, and has done what many of us have been aching to do since the sharp new sports car debuted on a frigid Detroit night – put it on the dyno. Using a Blade Silver Metallic Stingray, complete with the seven-speed manual transmission and the optional Z51 Performance Package, the team at Edmunds ran the C7 through a number of pulls.

The results were remarkably consistent, with a two-horsepower variation across four runs. After the initial sprints, the team took the Vette out for a few more dyno pulls, just to confirm the numbers. The average came out to 411 horsepower at the rear wheels and 407 pound-feet of torque, which is extremely impressive. Scroll down to watch the full video from Edmunds.

Video: You know you’ve always wanted to dyno a Barbie Power Wheels

Filed under: Videos, Toys/Games, Humor

When I was a kid, Power Wheels were all the rage. But my caring and loving parents refused to buy me one, no matter how many times I asked. My experiences with the machines back then were limited to test-drives at the local Toys R Us, or befriending the weird kid down the block just so I could take his for a spin every so often. Even today, Power Wheels are still a hit amongst youngsters, and although I’m a grown-up now (I guess) who gets to drive all sorts of, you know, real cars, I still get plenty jealous when I see some lucky kid cruising down the sidewalk in one of these machines.

I’m thankful, then, for companies like DBR High Performance. Because as the video below clearly shows, these awesome toys from my youth can still provide plenty of hilarity and excitement for adults. Here, the folks at DBR strapped Barbie’s iconic pink Power Wheels Mustang to a dyno to see just how much power this bad boy is putting down (in face-melting Rabbit Mode!).

Is it powerful? Goodness, no. But is it hilarious? Absolutely. Scroll down to see for yourself.

2011 bmw 1 series m on dyno

Inside Line straps the BMW 1 Series M to a dyno – Click above to watch video after the jump

It’s no secret that manufacturers sometimes underrate horsepower and torque figures for certain high performance models. This practice has been going on since the muscle car wars, and we don’t see it stopping anytime soon. Inside Line wanted to find out what the 2011 BMW 1 Series M is putting down for power, so rather than rely on the manufacturer’s information, the IL crew took a trip to the local dyno.

In case you’d forgotten, the 1 Series M is rated at 335 horsepower and 332 pound-feet of torque under normal operation, but an “overboost” function increases turbo pressure allowing the engine to make 369 pound-feet of torque for brief periods.

What happened when Inside Line hooked the 1M up to a rolling road? Let’s just say BMW is keeping the underrated power game alive. Click past the jump to watch the clip and see what we mean.

Home-built dyno is dangerously awesome – Click above to watch video after the jump

Tuning an engine can be a delicate procedure. There is a lot of time and patience required to dial things in just right. You can spend hours and big dollars adjusting parameters on an expensive professional dynamometer -or you can be a crafty Scandinavian and homebrew a dyno right in your yard.

Apparently, all it takes is the rear end from a heavy-duty truck, some straps and a quick skaal to Odin. The result is a snowed-in dyno that can tune all the V8-engine-swapped drift machines in the neighborhood. Click past the jump to watch ingenuity at work.

2011 Dodge Charger R/T hits the dyno

2011 Dodge Charger – Click above for high-res image gallery

Lift the hood of a 2011 Dodge Charger R/T and you’ll find a powerful 5.7-liter Hemi V8 engine bursting at the seams. It’s a joyous site that gets better when armed with the knowledge of the Hemi’s prodigious power – 370 horsepower and 395 pound-feet of torque, to be exact.

But just how accurate are those numbers? The folks over at Inside Line put the Charger R/T to the test on their dyno, and it appears Chrysler may be underplaying its hand. Tests by Inside Line show that the Charger R/T sends 360 hp to the rear wheels at 5,300 RPM, with torque peaking at 393 lb-ft at 4,260 RPM. When you consider that the average drivetrain accounts for a 10 to 15 percent power reduction before its all sent to the wheels, you’re looking at a powertrain with a lot more bite than the company brochure cares to admit. Head over to Inside Line to see the official horsepower and torque map.

Video: Hennessey Venom GT rocks the dyno, spits fire

Hennessey Venom GT dyno run

Hennessey channels Top Gun with its Venom GT – Click above to watch video after the jump

The Hennessey Venom GT is a beastly two-seater that produces as much power as a small sun. An LS9, taken from the Chevrolet Corvette ZR1, is massaged to produce an astonishing 933 horsepower and 874 pound-feet of torque at the rear wheels. If those numbers don’t scare you, we’re guessing you’re probably a naval aviator who is used to seeing the bright flash of afterburners coming to life. If so, you’re in luck because the Venom GT also spits hot fire.

We’ve seen it run on the dyno and we’ve also seen it produce a few flames from just off idle. Now we have video of Hennessey upping the ante by combining the two. While at full ~~song~~ scream, the Hennessey Venom GT belches a massive jet of fire out of its twin-exhaust outlets. Neato. Grab a stick, some marshmallows and click past the jump.

2011 Dodge Challenger SRT8 dyno’d – is the 392 underrated?

Filed under: Coupe, Performance, Dodge

2011 Dodge Challenger SRT8 on the dyno

Hemi. The mere mention of the word is enough to strike fear into the hearts of lesser powerplants… or at least images of a pair of scrubby-looking bottom-feeders that really love themselves some Ram Trucks. In any case, we’re keenly interested in the latest Hemi engine from the Dodge Boys, in this case displacing a heady 392 (or so) cubic inches and placed gently inside the engine bay of the 2011 Challenger SRT8.

Not only is this new Hemi larger than the already oversized version it replaces, it’s also considerably more potent. The Pentastar says that its new 392 kicks out 470 horsepower and 470 pound-feet of torque – substantial improvements over the outgoing SRT8’s 425 hp/420 lb-ft. But those are factory ratings, and we all know those don’t necessarily match what’s actually under the hood of production models.

Thankfully, the crew over at Inside Line managed to score enough time with a 2011 Challenger SRT8 to strap it down to a proper dyno. And the results? How about 452 horses at 6200 RPM and 443 lb-ft at 4400? Yep, that’ll do nicely, and it means that Dodge may actually be underrating its potent performer just a tad. Oh, and for what it’s worth, IL managed to record 370 horses and 343 lb-ft from its 2010 Chevrolet Camaro SS on the same exact dyno. Chevy’s answer ought to be coming in the form of a Z28 with over 500 supercharged ponies… Stay tuned, the horsepower wars are clearly still in full swing.

Video: Ford Shelby Mustang GT500 dyno run goes boom in spectacular fashion

Shelby GT500 blows up on the dyno

BOOM goes the GT500’s dyno might – Click above to watch video after the jump

Strapping a car to a dyno and giving it the boot is not as safe as it might seem. Sure, the car is not actually going anywhere, but a lot of forces are at play in the drivelline. The owner of this particular Shelby Mustang GT500 in the video available after the jump, learned this firsthand when his prized pony when boom.

No postmortem discussion is available to find out what happened, and we’re not sure what (if any) modifications were done to this previous-gen GT500, but it certainly sounded pretty mean right until it barfed up a lung. Hop the jump to check out the unfortunate carnage. Thanks for the tip, Brent W!

Video: Ever seen a V24 diesel rock the dyno?

V24 Detroit Diesel

24-cylinder Detroit Diesel madness: Click above to watch the video after the jump

Want to see something really crazy? How about a 24-cylinder Detroit Diesel engine with twelve giant blowers, all polished up and ready for its new assignment. For what it’s worth, its previous assignment was providing the motive force necessary to spin the propeller of a ocean-going yacht.

And its new assignment? Nestled tightly within the confines of a Peterbilt semi truck, mated up to an Allison transmission of some sort and mounted on a custom-built 40-foot-long chassis. Sounds pretty epic to us, and we’re thinking that 3,424 horsepower (our feeble brains are telling us it should have well over 5,000 pound-feet of torque…) ought to be just about enough.

And the man behind the madness? That would be Big Mike, the burly bearded millionaire you can read about in detail right here. Nicely done, Mr. Harrah. Hit the jump to see a video of this ridiculous piece of machinery make its first dyno run.

Dyno Tested: BMW’s past and present turbo sixes

Filed under: Coupe, Sedan, Performance, BMW, Luxury

2010 BMW 335i Sedan – Click above for high-res image gallery

BMW has always had a gem of an inline-six on its hands, regardless of which particular powerplant you’re referring to. But over the last couple of years, it’s the German automaker’s turbocharged 3.0-liter N54 engines that have been lighting enthusiasts hearts afire, and steering more than a few buyers away from the M3 and into the seat of a 335i. And when the N54 proliferated across the rest of the automaker’s lineup, it was well-received in nearly every application.

For 2011, though, there’s a new engine in town, and the big question is whether or not the single-turbo N55 is better than the previous twin-turbo N54 or, at the very least, not worse. Helping shed some light on the matter is the crew from Automobile Magazine, who managed to snag a trio of various N54-powered 3-Series’ – one of which was the hotted-up 2011 335is, which uses a high-output version of the old N54 – along with one new model powered by an N55.

And the results? Well, it’s pretty much more of the same: good peak horsepower (266 horses) and a nicely flat mid-heavy torque curve, cresting at a stout 302 pound-feet. But we’d be remiss if we didn’t point out that the new N55, while seemingly offering less turbo lag than its predecessor, appears to be a wee bit less powerful overall than the N54. Progress?
