Tesla Model S finally has its date with a dyno

Jeffrey N. Ross — Thu, 17 Jan 2013 14:58:00 EST

Filed under: Performance, Videos, Hatchback, Tesla, Electric, Luxury

The performance abilities - and even the burnout potential - of the Tesla Model S has already been well documented, but, surprisingly, we haven't yet seen the all-electric luxury hatchback strapped to a dyno. Fortunately, the crew over at Dragtimes has posted a video that finally gave us some real-world numbers for the family- and environmentally friendly Tesla.

As the article points out, the results might be off a little (on the low side) due to the run not starting from a dead stop, but the numbers are impressive nonetheless. Immediately upon throttle application, the dyno records almost 300 horsepower at zero miles per hour, and power peaks at 368 hp at around 55 mph (we imagine the "386HP" quoted on the video title is a typo) before trailing off to around 220 hp closer to the car's limited 130-mph top speed. This compares quite favorably to the power numbers provided by Tesla putting max output at 416 hp; the dyno provided no torque figures for the car. Dragtimes also believes this number bodes well for the car on the track, too, quoting a quarter-mile time of 12.2 seconds at 112 mph.

The video of the quiet, zero-emission dyno session is posted below, so check it out.

2013 SRT Viper GTS dyno'd by Edmunds

Seyth Miersma — Thu, 03 Jan 2013 12:45:00 EST

Filed under: Coupe, Performance, Videos, SRT

First-time dynamometer runs for any production car are interesting business, at least for those with "car nerd" in their resumes. And the virgin public dyno testing of a new supercar like the SRT Viper GTS, well, that's just a bit o' heaven right there. So, when we heard that the number crunchers at Edmunds had gotten the new Viper into the test facility, we were hooked right away.

We won't spoil the video for you by blowing the ending right here, but suffice it to say that the SRT 8.4-liter V10, rated at 640 horsepower and 600 pound-feet of torque at the crank, is still pretty super by the time the power makes its way to those wide rear tires. Follow on below for the fun.

2013 BMW M5 may have more horsepower than reported

Jeffrey N. Ross — Fri, 07 Sep 2012 14:15:00 EST

Filed under: Sedan, Performance, BMW

With the 2013 BMW M5 finally going on sale in the U.S., we definitely saw this coming. BimmerBoost recently got a hold of engine dyno run for the new M5, and is reporting that the car's twin-turbo V8 is "severely" underrated.

Officially, the M5's 4.4-liter V8 is rated at 560 horsepower and 500 pound-feet of torque, but the dyno graph reveals numbers at the rear wheels to be 527 hp and 476 lb-ft in completely stock form. While the idea of the engine being underrated is just an assumption, the general rule of thumb is a 15-percent drivetrain loss - if accurate, the new M5's losses would be just six percent. Using the 15-percent rule, the 2013 M5 would lay down 476 hp at the wheels.

The idea of BMW underrating its engine outputs is nothing new. Earlier this year, the new 328i show some impressive numbers of its own.

Chevy Camaro ZL1 lines up against Ford Shelby GT500 on the dyno

Jonathon Ramsey — Wed, 06 Jun 2012 12:45:00 EST

Filed under: Coupe, Performance, Videos, Chevrolet, Ford

Inside Line took the 2012 Chevrolet Camaro ZL1 and 2013 Ford Mustang Shelby GT500, together, on a field trip: to Westminster, California where where they were both tested on the same dyno at MD Automotive, run the by same operator on the same day. In case any memories need refreshing, the specs run thusly: the ZL1 has a 6.2-liter supercharged V8 belting out 580 horsepower at 6,000 rpm and 556 pound-feet of torque at 4,200 rpm, for a 0-60 time of 3.9 seconds and a top speed of 184 miles per hour. The Shelby GT500 rocks up with a supercharged 5.8-liter boasting 662 hp and 631 lb-ft, for a 0-60 time of 3.7 seconds and a top speed in excess of 200 mph. Both get the power down via six-speed manual transmissions.

All things being equal, the dyno returns should have them split by something like 82 hp and 75 lb-ft. But good luck with equality, at least on this day: the Camaro charted 497 hp and 497 lb-ft, a the kind of 15 percent drop you might expect due to driveline losses, and just 11 percent of its torque sapped.

The GT500 would have none of it, charting 595 hp and 603 lb-ft. That leaves an on-the-road gap of 98-hp to the ZL1, and even though it loses more torque percentage-wise, it still comes out at an absolutely insane 603 lb-ft.

This latest info gives a new round of ammo to the armchair testers until the comparos start rolling in. But as numerous folks have commented on the dyno tests, what's really important is this: this is a great time to be a car enthusiast in America. Scroll down to check out the video.

First Toyota FT-86 coupe dyno'd

Zach Bowman — Tue, 24 Jan 2012 11:01:00 EST

Filed under: Motorsports, Coupe, Performance, Etc., Japan, Videos, Toyota

Well, that didn't take long. The First Toyota FT-86 (a.k.a. Scion FR-S) has made its way to the dyno courtesy of the good people at HKS. How'd it do? The vehicle managed to spin the rollers at 170 rear-wheel horsepower, which dovetails with the 200 crank horsepower announced by Toyota and Subaru after calculating a 15-percent driveline loss. Of course, whenever HKS gets involved, you can feel safe betting your lunch money that forced induction won't be far behind. True to form, HKS showed off its handiwork on a drift car version of the new sports coupe from Toyota.

The FT-86 looks more than happy to dance through a few chicanes sideways, and we can't wait to see the vehicle go fender-to-fender with the best of them. Click past the jump to check out the dyno video for yourself.

2012 BMW M5 gets dyno'd, all ate up with power

Jonathon Ramsey — Mon, 26 Dec 2011 19:29:00 EST

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

A German tuning outfit called PP-Performance has put the 2012 BMW M5 on a Maha dyno, and the numbers returned were 444 horsepower at the wheel, 553 at the engine, and a "corrected number" of 574 hp. Max torque came in at 532 pound-feet (721 Newton/meters).

Compare those figures to the official numbers of 560 horses and 502 lb-ft. If the 444 number is accurate, then no matter how you slice it on horsepower - whether you use the numbers from BMW or PP-P's figures - you're losing around 20 percent from the engine to the wheels. However, adjusting for driveline and twin-turbo losses, that puts things right about where they should be. The 30-lb-ft surplus of torque, on the other hand, is the kind of surplus no one would complain about - again, assuming it's accurate.

Follow the jump for video of the dyno run, and for another vid of the M5 being taken to 293 km/hr (182 mph). And with that second vid, try to ignore the fact that the terminal velocity attempt is being conducted on an engine with just 40 kilometers on it...

AEM lets you hook up your car to a dyno at home with Dyno-Shaft

Zach Bowman — Wed, 23 Nov 2011 18:01:00 EST

Filed under: Aftermarket, Etc., Technology

Unless you happen to own a dyno, accurately keeping track of which modifications benefit your vehicle may be a seat-of-the-pants operation. AEM is hoping to change that for people who are serious about wringing the absolute most out of their vehicle with the unfortunately-named Dyno-Shaft.

While the product may sound like a bizarre fetish film, it has the potential to revolutionize tuning for those of us who don't have access to high-dollar engine evaluation equipment. The Dyno-Shaft uses grade-strain gauges to measure horsepower and torque at transmission output shaft, so AEM maintains that the system's readings aren't impacted by variables that typically skew accelerometer readings.

AEM says that the the data broadcast device for the system is non-contact, doesn't use slip rings and needs no batteries, all of which are good things. Buyers simply install the supplied slip-yoke as well as a drive-shaft speed sensor and get going. Data is transmitted via a CAN-bus communications network to a data logger or an AEM engine management system. Prices start at $1,160.96 for cast-iron slip yolk applications, and AEM says that each Dyno-Shaft is specifically calibrated for your application. Chrome moly yolks are also available for higher-horsepower applications. We desperately want to play with one of these to see how accurate it is compared to a traditional full dyno setup.

Russian tuner squeezes 1,000 horsepower into a Fiat Coupe

Noah Joseph — Thu, 27 Oct 2011 16:57:00 EST

Filed under: Aftermarket, Coupe, Performance, Videos, Mitsubishi, Russia, Fiat

You may remember a fun little hatchback called the Fiat Panda 100HP. All it took was a hundred horsepower to turn a ho-hum supermini into what European editors knew and loved as one of their favorite driving machines. That was a little overshadowed by the Fiat 500 that offers the same powertrain, if not all the same fun, but the Panda put things into perspective. Especially considering now how one tuner has taken an earlier Fiat Coupe and squeezed a whopping 1,000 horsepower out of it. That's ten times as much.

So how'd they do it? Well, for starters they scrapped the stock engine and shoehorned in the twin-turbo V6 from the Mitsubishi 300GT VR-4. Advanced though it was for its time, with its 24 valves and dual overhead cams, the Diamond Star engine never produced more than 300 horsepower in stock form. So the tuner performed some undisclosed magic on it and boosted the output up over three times its stock figure.

While they were at it, they also squeezed the Mitsu's advanced all-wheel-drive, four-wheel-steering system in there. Because as bonkers as 1,000 horsepower is by any account, trying to keep that much twist on the straight and narrow when it's just driving the front wheels would be a nightmare. This, on the other hand, is clearly someone's dream come true. Check it out in the trio of videos after the jump.

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: 2011 Dodge Charger R/T and Challenger SRT8 392 make more power than expected

2011 Dodge Charger R/T and Challenger SRT8 392 - Click above to watch the video after the break

As part of its Hemi Highway Tour, a country-wide tour that started in November of 2010 and just recently came to its end, Dodge decided to stop and spend some quality time with the boys and girls from National Speed in Wilmington, NC. Though that company's main purpose is modifying high-performance machinery to make even more power, Dodge decided to put a couple of its brand new 2011 models on their dyno to see what kind of power could be had right off the showroom floor.

As a preface to the actual dyno results, you should know that Ralph Gilles, Dodge Car Brand President and CEO, claims that a bone-stock 2011 Challenger SRT8 392 ran the quarter-mile at Infineon Dragway in just 12.44 seconds at 110 miles per hour. That, boys and girls, is seriously fast. And those figures are backed up by the data spat out by the computers hooked to National Speed's dyno.

Without further ado, the numbers: The 2011 Dodge Charger R/T put down 327 horsepower at the rear wheels and 349 pound-feet of torque. For a car rated at 368 horses and 395 lb-ft, that's quite good. Remember, the dyno measures power after it's already gone through the transmission and through the wheels to the ground, which saps around 15 percent of total power.

And now on to the big guns. The 2011 Challenger SRT8 392 was measured at 420 rear-wheel horsepower and 419 lb-ft of torque. Also impressive when stacked up against its factory ratings of 470 ponies and pound-feet. Even more interesting, these same machines put down ever more power just a few days later on a different dyno, though still below the 452 horses obtained by the scribes at Inside Line. Enough talking already. Check out the video after the break. Thanks for the tip, Norm!

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.

Mitsubish Evo dyno disaster - Click above to watch video after the jump

Under the right conditions, testing a vehicle on a dyno is a safe way to get a good idea of how much power your engine is producing. It's also an excellent tool for precision tuning, so if you're into squeezing all you can out of your car's beating heart, chance are you're going to be ponying up for time on the rollers. Just make sure that the shop that's doing your dyno work knows how to properly secure your vehicle. If they don't, you could end up like owner of the poor Mitsubish Evo in the video after the jump.

Apparently not long after laying down a 450-horsepower run, the all-wheel drive monster set about launching itself from the platform, bouncing off of a support post. Something tells us it's going to take a fair bit of buffing to smooth out the Mitsu's sheetmetal, and maybe a bit longer for the dyno operators to smooth things over with the boss. Hit the jump to check out the carnage for yourself.

2011 Dodge Challenger SRT8 dyno'd - is the 392 underrated?

Jeremy Korzeniewski — Fri, 03 Dec 2010 19:30:00 EST

Filed under: Coupe, Performance, Dodge

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.

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.

Hyundai Sonata and Sonata Turbo hit the dyno - Click above to watch video after the jump

Inside Line put the Hyundai Sonata 2.0T on a dyno to see how much gumption the wheels were actually getting from the flywheel. Not uncommon for Hyundai, there are two sets of numbers to deal with in the beginning: the 2.0T is rated at 274 horsepower and 269 lb-ft on 87 octane, but IL was told that it could get ten more horses from 93 octane. Using 91 octane, the site figured it has about another six to eight ponies in the bag.

Having registered 234 peak hp at 6,100 rpm and 239 lb-ft at 3,500 rpm, driveline losses counted for a 20-percent drain in horsepower (from 280) and about 12 percent of torque. By comparison, when the non-turbo Sonata was tested, the percentage losses were slightly lower in both categories.

The turbo was praised for its consistent pulls and real-world acceleration (especially under partial throttle), as well as seamless boost anywhere in the rev range. Nevertheless, Inside Line's Jason Kavanagh wonders, "I'm curious as to where a few ponies wandered off." Follow the jump to watch the dyno test.

Hennessey Venom GT - Click above to watch video after the jump

By now we should all know that Hennessey isn't the kind of vaporware tuner that throws out a rendering, some wild projected power numbers and then drops off the face of the planet, but that didn't stop us from being skeptical when the Texas-based tuner/builder rolled out plans for its Venom GT. Originally, the car was supposed to get its power from a beefy V10 borrowed from the nose of a Dodge Viper, complete with a 1,000-horsepower tune in a 2,700-lb chassis. The final product, however, swapped the 10-pot for the supercharged V8 found in the mighty Chevrolet Corvette ZR1. Despite dropping two cylinders, horsepower estimates stayed the same.

Now Hennessey has rolled out a video of its creation on the dyno. How does a streetable 933 horsepower at the rear wheels sound? How about 874 lb-ft of torque at the tires? It sounds mighty tasty to us, especially considering that those numbers come courtesy of regular 93 octane pump gas (no race fuel here, kiddies) and, again, are at the wheel. Ditch the drivetrain loss and power at the crank will easily crest 1,000 ponies. Go ahead and hit the jump to see the monster pull for yourself.

Video: Hennessey gets Ford's SVT Raptor 6.2-liter rippin' on a dyno

Ford F-150 SVT Raptor 6.2 gets dyno'd - Click above to watch the video after the jump

The 6.2-liter V8-powered Ford F-150 SVT Raptor went on sale less than two weeks ago and Ford tells us that it already has 3,000 orders signed, sealed and awaiting delivery. While that would spell disaster for the Blue Oval if we were talking about the run-of-the-mill F-150, we're talking about a purpose-built performance truck brandishing Fox shocks and massive 35-inch tires. Given the vehicle's niche audience, those kind of early sales numbers have Ford officials pretty excited. Make no mistake, the reason for all that interest has everything to do with the extra 91 horsepower under the Raptor's beefy hood, and the folks at Hennessey dyno'd the Little Mule to see just how much power transfers to those massive rear wheels. If you're wondering why Hennessey is interested in the Raptor, remember that the super tuner announced the 500 horsepower VelociRaptor back in February.

The post-jump video shows that, on the Hennessey dyno, the Raptor managed 326 horsepower and 343 pound-feet of torque. Keep in mind that the 326 ponies are measured at the rear wheels, where drivetrain losses zap power. Ford quotes 411 hp and 434 lb-ft at the flywheel, which means the vehicle Hennessey dyno'd experienced a 19.5 percent loss from the flywheel to the rear wheels. Hit the jump to watch the video, which includes a zero-to-60 time of less than eight seconds.

We wouldn't blame you if you threw a skeptical eye on the 2010 Cadillac CTS-V Hennessey V700 power claims. After all, more than 700 horsepower at the crank is hefty chunk of grunt, even from a supercharged small block. Fortunately, John Hennessey has been kind enough to allow the kids at Inside Line to stick his four-door beastie on the rollers for all to see. How'd it do?

The big-bad Cadillac put down 636 horsepower and 656 lb-ft of torque. Run those figures through the time-tested 15-percent driveline loss, and Hennessey's claims of world-dominating horsepower seem pretty close to the mark. No wonder the breathed-on Caddy is so good at obliterating its tires. Click past the jump for a video of the fire-breathing action.
