Any car that comes from the factory with 707 hp ( ) deserves it's own thread.



707hp
650 ft-lb torque.

Fricking A...

I make a bunch of parts that are in that car......but I probably won't ever actually see one.

They added more NVH insulation to tone down the supercharger noise in the cabin.

Cool, another 11/10ths scale car

But yeah, 707hp... indeed

Quote :

"It’s official: the Dodge Challenger SRT Hellcat is the most powerful production muscle car ever—and even more powerful than the Viper supercar, with 707 horsepower and 650 pound-feet of torque on tap. The massive power output dwarfs even the previous ludicrous power title-holder, the 2013 Ford Mustang Shelby GT500, which rates 662 horses. Generating its power from a 6.2-liter supercharged HEMI V-8, the Challenger SRT Hellcat won’t always be a complete handful to drive, however, thanks to a dual key fob system. The black fob limits the car’s output to 500 horsepower; opt for the red key fob, and you’ll get the full 707. We hear the potent powerplant may also make its way into the 2015 Charger. A TorqueFlite eight-speed transmission, uprated suspension and classic 1971 Challenger-inspired interior design are also part of the Hellcat package. The first examples should reach the market in the third quarter of 2014. You can listen to it rev below."

Also who switches keys for 500hp.

If you gave me a 300hp key so I could let my hypothetical kid take it out... Sure...
But 500? That's just gonna cause you to lose a stoplight war saying hold on while I switch my keys.

7/2/2014 12:57:49 PM

How would that amount of hp be useful <70mph?

7/2/2014 1:09:37 PM

^^ also has a 6 speed manual available.

7/2/2014 1:53:35 PM

TheDuke866: does it have a black box? yes? don't want.

"“From an engineering perspective, to do really significant mass reductions we’d need an all-new architecture,” she said. “For example, changing to an aluminum decklid, roof panel, and doors would net us some useful gains but it wouldn’t take us down a full weight class, which is 300 pounds. So we concentrated on bringing in the eight-speed, the EPS, and numerous other changes such as engineering new four-point rear cradle mounts (versus the 2014’s three-point mounts). And Nexteer was great to work with during development of the steering system, by the way!”"

Hey theduke866, those black boxes are how they proved General Motors was to blame in their ongoing ignition-switch-off-prior-to-crashes fiasco. Those black boxes are going to cost them $billions.

7/3/2014 8:08:01 PM

I bet you this thing is pushing some serious boos for 707 hp
Anyone know what blower is on it and how many psi yet?

^^ I bet it's not cute little blower whine I bet it's down right fuggin annoying.

7/3/2014 9:06:47 PM

^^ the blame should be the shitty drivers and intoxication. Loss of power does not equal dieing unless you screw up a lot of other stuff as well.

7/3/2014 11:44:55 PM

^I've experienced the very thing for which this recall is occurring in my wife's former Olds Alero. And if you're not expecting it--on that car, things as small as a minor bump in the road could cause it to cut off--the loss of power assist on your steering and brakes is quite surprising, especially the first time it ever happens. If that were to coincide with someone slamming on brakes in front of you, a sharp turn in the road, etc, you might be screwed.

Of course this was in 2010, well before the recall, so I had to buy a replacement ignition switch and install it myself. Thanks, GM.

7/3/2014 11:48:47 PM

^I can admit that an unexpected stalled engine is startling

especially when it's a 3/4ton truck and you almost cannot turn the wheel or use brakes (hydroboost)

7/4/2014 6:27:38 PM

Getting back OT.

Looks like this engine will also be available in the Charger. Talk about a family hauler

7/10/2014 9:45:14 AM

Give me this engine in a charger with a t-6060 trans and I'll be a happy man...

Fuck that's about what I'm building in my galaxie.

7/10/2014 10:16:50 AM

I wonder what the price will be.... $75k like the camero?

7/10/2014 11:20:03 AM

Probably.

Even though it's not quite the same.

7/10/2014 11:25:27 AM

I was thinking of this. Dodge times the hellcat perfect to steal the thunder from the new irs mustang.

2015 Dodge Challenger Hellcat Runs 11.2-Second Quarter on Street Tires
10.8 Seconds on Drag Radials

When the power figures for the new 2015 Dodge Challenger SRT Hellcat were revealed as 707 hp and 650 lb-ft of torque, it was not only the most powerful muscle car, but also the most powerful regular production American car ever. Now the automaker has released official drag strip times. The Challenger Hellcat ran the quarter-mile in 11.2 seconds at 125 mph on street tires, and did the deed in 10.8 seconds at 126 mph on drag radials.
More on Motortrend.com:2015 Dodge Challenger SRT First Look
Those times, which are NHRA-certified, make the 2015 Dodge Challenger Hellcat the fastest muscle car ever. In our testing, the 662-hp 2013 Ford Shelby GT500 ran the quarter-mile in 11.6 seconds at 125.7 mph, while the 580-hp 2012 Chevrolet Camaro ZL1 posted 12.1 seconds at 117.4 mph. While Dodge has been mum on the Challenger SRT Hellcat’s curb weight, the last 2011 Dodge Challenger SRT we tested weighed 4260 pounds. With a 470-hp 6.4-liter Hemi V-8, that model ran the quarter-mile in 13.0 seconds at 111.3 mph. For reference, the Shelby GT500 tipped the scales at 3871 pounds and the Camaro ZL1 at 4051 pounds.

The 11.2-second run was made on the 2015 Dodge Challenger Hellcat coupe’s stock -- and relatively narrow -- Pirelli P Zero tires sized P275/20R20. Power for the Challenger Hellcat comes from a supercharged 6.2-liter Hemi V-8 mated to either a six-speed manual or eight-speed automatic transmission.

are those times with the auto or stick

7/11/2014 6:02:33 PM

Mustang has .18 less pounds per hp and would/should win with slicks and a decent guy rowing the gears.

I call bs 5.84 vs 6.02 lb/hp tells the story of the fast bull vs the horse.

7/11/2014 7:11:40 PM

we need to see the power curves

7/11/2014 11:04:43 PM

It's a twin screw. And it sounds absolutely nasty in person.

7/12/2014 1:48:15 AM

Ford rep rolled his eyes at the hellcat on cnn.

Said the next gt500 should exceed that.

7/15/2014 12:46:59 PM

GLORY DAYS

7/15/2014 1:12:31 PM

when can i expect the next z06 or zr1?

7/15/2014 1:52:36 PM

Zo6 is on it's way out soon and is essentially powered by the old zr1 motor.

I mean obviously he's not going to act like he's impressed either way. As to the next GT500 I guess we'll see. They still gonna be using the Triton engine? I keep hearing that they wanna get away from that engine.

7/15/2014 4:36:42 PM

The plasma bore 5.8 wasn't cost effective at low volumes.
They either need to put it in something else or ditch it.

It's not a triton engine those are the 2/3 valve iron truck mod motors.
The triton 5.4 is going to be gone too. I'm wondering about the hurricane motor.

I'm wondering if we get a 5.0 ecoboost some day but more than likely just a blown stroked coyote.
Those heads breath so well you'd be dumb not to use them.

only in the sense that it's 6.2 liters and supercharged. The new LT4 has direct injection. I'm not sure if it keeps the cylinder deactivation and cam phaser.

7/15/2014 8:30:48 PM

I actually didn't know it was direct injected.

Thanks for the correction. When I typed that I was like "I know this is (also) a truck engine name, so it can't be right" but just couldn't remember properly.

Doesn't leaked info keep coming out about a Shelby GT350 with a flat plane V8? Or are those rumors dead?

http://www.caranddriver.com/news/2016-ford-mustang-shelby-gt350-spy-photos-news

The more agile GT350, on the other hand, will get a naturally aspirated V-8 with—look out, Ferrari—a flat-plane crankshaft. This so-called “Voodoo” engine will be a modified iteration of the regular Mustang GT’s 5.0-liter Coyote mill, and it should rev to at least 8000 rpm and pump out 550 Z/28–slaying horsepower

7/16/2014 8:32:00 AM

rednecks are going to complain about how it sounds.

That's nasty

7/16/2014 9:29:49 PM

that 1.5 gallons a minute is a silly marketing thing. I'm pretty sure they took the fuel volume flow rate at steady-state peak power on an engine dyno and converted it into some miles per gallon equivalency.

7/16/2014 10:04:30 PM

Bsfc is usually well documented by oems right?

7/16/2014 10:24:30 PM

The only place you will get it is from some technical paper or article published. Here is a BSFC map for the 2.4 liter turbo engine in the Caliber SRT-4:



You can't calculate BSFC accurately without putting the engine on an engine dyno with the right equipment. You calculate it based on the lower heating value of the fuel (the amount of energy it contains), the torque/brake mean effective pressure, and the fuel mass flow. Typical SI unit is grams/(kilowatt*hour) as shown above. So that means you need:

1) an engine dyno. Eddy current or water brake will work if you can fire it with a starter, plus you need at least some way of controlling coolant temperature in the engine.

2) some means of getting the engine to run right on a dyno without throwing a gazillion codes (on modern engines)

3) a fuel flow meter in the supply line

4) a fuel sample sent off to a lab to measure lower heating value. It can vary significantly, unless you are using certification fuel which is $Texas

Now you can back calculate it with virtual dyno type programs/spreadsheets but the error is significant there. You could take the airflow reading from the MAF sensor, back calculate fuel flow rate based on wideband o2 reading for air-fuel ratio, guess the crank torque/BMEP based on measured wheel torque, guess the lower heating value based on an assumed LHV for gasoline and an assumed ethanol content.
