Nice videos! It's great to see more videos of the car being driven.

I can't wait to see some videos of NorthernRider at the wheel! :)

From Car & Driver,
There are many details about the Hellcat engine that may not have been posted before. Its a fairly technical read.

Ten Shades of Hell: 10 Things We Learned About the Stonking, 707-hp Hellcat V-8

Chris Cowland, Chrysler’s director of advanced and SRT powertrain, recently came clean with the engineering secrets behind the 707-hp 6.2-liter Hellcat V-8. In case you just stirred from suspended animation, this Dodge Challenger SRT engine is the most potent powerplant ever sold to customers for road use by any American manufacturer.

Revelation 1: While this Hemi is a cousin to 5.7-, 6.1-, and 6.4-liter Chrysler-built V-8 engines, the Hellcat is, for all intents, a new design sharing only basic architecture—such as a 103.9-mm bore—with its predecessors.

More than 90 percent of the components (by value, not parts count) are new. The cast-iron block has thicker webs and larger cooling passages to support the added power and stress. The induction-hardened forged-steel crankshaft provides the desired 90.9-mm stroke. The powder-forged steel connecting rods have cracked bearing caps for more secure clamping. New forged-aluminum pistons withstand more than 21,000 pounds of combustion pressure. The 24-mm wrist pins have a diamondlike coating for minimal friction

Revelation 2: While the uninformed may deem an iron cylinder block to be yester-tech, Cowland insists it’s the ideal material for this application given the intense loading. While a fresh aluminum design might save a few pounds, package dimensions would surely be larger due to aluminum’s significantly lower stiffness. The hard-working, fast-spinning Hellcat crankshaft is well supported by the iron block’s deep side skirts and twenty bolts securing the five main-bearing caps. A meaty closed upper deck resists cylinder-bore distortion.

Revelation 3: While the heat-treated A356 aluminum cylinder heads do not have hemispherical combustion chambers, they do carry huge 54.3-mm (2.14-inch) intake valves and 42.0-mm (1.65-inch) exhaust valves. Both have hollow stems to save weight; the exhaust stems are sodium-filled to dispense with excess heat.

Revelation 4: IHI Turbo America (formerly Warner-Ishi) manufactures the entire 80-pound supercharger—aluminum housing, aluminum rotors supported by steel shafts, and the twin air-liquid intercoolers—in a Shelbyville, Illinois, plant. A one-way clutch on the blower’s input shaft prevents the high-inertia rotating components from back-driving the engine during lift-throttle conditions. More potent than a street sweeper, this blower can move 30,000 liters of air per minute. IHI earned this business in a fly-off against two other supercharger suppliers.

Revelation 5: Spinning the twin-screw IHI supercharger is a substantial engineering feat. Washers securing the 10-rib drive pulley to the crankshaft are infused with industrial diamonds to provide sufficient clamping friction. Driving the blower 2.36 times crankshaft rpm to deliver 2.4 liters of air per revolution consumes 80 horsepower. The asymmetrical supercharger rotors spin at different speeds thanks to their interlocking configuration and 3:5-ratio phase gears at the back of the blower. At the 6000-rpm engine horsepower peak, the rotor spun by the belt from the crankshaft turns at 14,160 rpm while its mate spins at 23,600 rpm.

The rotors are coated with a Teflon material that helps maintain the tight clearances needed to prevent airflow leaks. In the event of accidental contact, the soft coating abrades instead of the aluminum rotor material. Gears and rotor bearings are lubricated by a sealed-for-life splash system containing synthetic oil. Durability was proven by canting the blower at 47 degrees from horizontal and running it at different speeds and loads for 300 test hours.

Revelation 6: Noise generated by the supercharger is engineered to please the obvious Hellcat users: individuals with a stout performance bent. During idle and part-throttle driving, the bearing, gear, rotor, and airflow ruckus falls below the audible threshold. Kick the gas and you hear a subtle whine mixed in with the louder intake and exhaust sounds. No artificial noise is added via the car’s sound system.

Revelation 7: To cool the intake air and maximize its density, a 250-watt (1/3-horsepower) thermostatically controlled electric pump moves 45 liters of coolant per minute through the two heat exchangers (intercoolers) built into the flanks of the supercharger and the two radiators positioned at the front of the car. The goal is to reduce the temperature of the intake air to less than 140 degrees Fahrenheit so the water and antifreeze mixture is maintained at about 100 degrees F.

Revelation 8: The fuel lines are 0.5 inch in diameter to quench Hellcat’s thirst for gasoline, while the air-fuel ratio is regulated by using both speed-density and mass airflow calculations (doubling up was necessary to satisfy onboard diagnostics requirements). Although direct injection was considered, suitable high-pressure delivery pumps with the required capacity do not exist.

The eight fuel injectors positioned in the intake runners deliver up to 630 cc of gasoline per minute (or one pint every six seconds). The injector orifices are drilled at a 20-degree angle to aim the 17-degree cone of atomized fuel at the back side of the intake valve. Delivery is nearly continuous to ensure that adequate fuel to support 707 horsepower is delivered. The heat of the intake valve vaporizes the microdroplets of gasoline before they enter the combustion chambers. Two air intakes are provided in the Hellcat Challenger: one at the center of a driver’s-side lamp located in the grille, the other at the bottom of an underhood filter housing.

Revelation 9: A high-capacity engine oil cooler is standard Hellcat equipment. The factory-fill lubricant is Pennzoil Ultra Synthetic oil in a 0w40 viscosity grade. A total of six heat exchangers live at the front of each Challenger SRT powered by this engine.

Revelation 10: The Hellcat V-8 is offered with a choice of a Tremec TR-6060 six-speed manual transmission or a ZF/TorqueFlite paddle-shifted 8HP90 eight-speed automatic. Both are upgraded for this application and equipped with lubricant coolers.

A twin-disc 10.2-inch clutch feeds torque to the manual ’box. Launch control is provided with both transmissions to help novices burn less rubber and waste minimal time off the line. The automatic starts in second gear in launch mode. Thanks to the wide ratio spreads and tall top gears, the Challenger SRT achieves up to 22 mpg in EPA highway tests. Unfortunately, its 13 mpg in city driving results in a $1700 gas-guzzler tax penalty.

--------------------------------------------------------------------------------

BONUS Revelation: Each Hellcat V-8 receives a 42-minute dyno run at the Saltillo, Mexico, manufacturing plant for break-in. Maximum rpm is 5200 at 90-percent load.

Chris Cowland was generous in sharing his expertise but anxious to move forward with the next project: The unconfirmed 800-hp supercharged V-10 under development to give the Dodge Viper enough venom to bite both the feisty Challenger and Charger SRT Hellcats.

SRT Hellcat No. 1 raises $1.65 million for charity


This one-of-a-kind 2015 Dodge Challenger SRT Hellcat VIN0001, hand-painted Stryker Red, sold for $825,000 at the Barrett-Jackson Auction in Las Vegas last weekend.

Dodge auctioned the first production 707-horsepower 2015 Dodge Challenger SRT Hellcat VIN0001, the most powerful and fastest muscle car ever, for $825,000 at the Sept. 27 Barrett-Jackson Las Vegas 2014 auction.

The auction benefitted Opportunity Village, a nonprofit organization that serves people with significant intellectual disabilities in the Las Vegas area. The Engelstad Family Foundation of Las Vegas matched the auction price, bringing the grand total raised for Opportunity Village to $1.65 million.

With the Engelstad family’s generous donation, the Challenger SRT Hellcat raised more money for charity than any other car in Barrett-Jackson history. Barrett-Jackson waved all bidding and consignment fees, so 100 percent of the sale price goes to the charity.

“The $1.65 million raised by auctioning this one-of-one Dodge Challenger Hellcat at this year’s Barrett-Jackson auction means the most powerful muscle car ever also will have a very powerful impact on the people who benefit from the services of Opportunity Village,” Tim Kuniskis, President and CEO—Dodge and SRT Brands, said. “The VIN0001 muscle car was not only one of the hottest cars that rolled through the Barrett-Jackson auction lanes, it also is the ultimate collectible 2015 Dodge Challenger as Dodge is ensuring there will never be another one like it.”

The one-of-one special edition Challenger SRT Hellcat, with a 6.2-liter supercharged HEMI® V-8 engine and 0001 vehicle identification number (VIN), has an NHRA-certified quarter-mile time of 10.8 seconds at 126 mph with drag radials, 707 horsepower and 650 lb.-ft. of torque on tap right from the assembly line. Adding to the exclusivity, the donated muscle car is the only Challenger to ever have a Viper-exclusive Stryker Red exterior—hand-painted at the Dodge Viper paint facility—and it includes special Hellcat badging on the instrument panel and supercharger, specific VIN documentation and one-of-a-kind memorabilia.

The Challenger SRT Hellcat VIN0001 has a class-exclusive TorqueFlite eight-speed paddle-shift automatic transmission with rev-matching downshifts, 15.4-inch Brembo front disc brakes with two-piece rotors and six-piston calipers, the largest brakes ever offered by Chrysler Group and 20-inch-by-9.5-inch lightweight matte black forged-aluminum wheels. The vehicle will have newly designed interior trimmed in premium Black Laguna leather on performance-oriented seats, a modern dash layout featuring the 8.4-inch Uconnect touchscreen and an authentic forged-aluminum supercharger plenum cover under the hood.

The auction package includes a 6.2-liter supercharger engine cover and a HEMI Orange painted base presentation box with a VIN0001 electronic vehicle build book and a video documentary on an iPad mini that shows the step-by-step build process of the car. The one-of-a-kind presentation box also includes still shots, vehicle footage, a customized key fob holder, an authentic Challenger SRT Hellcat embossed Laguna Leather iPad sleeve, a SRT Hellcat lithograph and unique “birth certificate” for VIN0001. Additional information on the vehicle is available on the news feed page of SRT | Street and Racing Technology | driveSRT.

The auction benefitted Opportunity Village, a nonprofit organization that serves people with significant intellectual disabilities in the Las Vegas area.

Rick Hendrick, owner of Hendrick Motorsports and several Chrysler Group dealerships, was the winning bidder at the auction.

The Engelstad Family Foundation was established in 2002 in honor of family patriarch Ralph Engelstad. Since then, the foundation has donated generously to the Las Vegas community.

“We are so unbelievably thankful for the support of Dodge and Barrett-Jackson,” Linda Smith, Associate Executive Director, Opportunity Village, stated. “We are touched by their amazing generosity and support of our mission here to support individuals with disabilities by giving them the chance to lead independent and fulfilling lives.”

Barrett-Jackson, prides itself as the world’s greatest collector car auctions, was founded in Scottsdale, Ariz., in 1971. Its internationally renowned auctions are hosted in Scottsdale; Palm Beach, Fla.; Reno/Tahoe, Nev., and Las Vegas, and features hundreds of the world’s most sought-after, unique and valuable vehicles where they cross the block in front of a global audience.

“With 707 horsepower, the 2015 Dodge Hellcat is more than just the most powerful muscle car built by an American manufacturer,” Craig Jackson, chairman and CEO of Barrett-Jackson Auction Co., said. “It is also the means to help countless people with severe intellectual and related disabilities reach their potential. We’re honored that Dodge chose our 2014 Las Vegas auction to sell Hellcat VIN0001 to support Opportunity Village. Not only will the wonderful people at this organization benefit from the sale of this muscle car, but the winning bidder will own a truly amazing piece of American automotive history.”

Sorry guys, but the wagon wasn't modded other than the 3 yr old tires it had on and in that turn he actually let Ralph pass. (There were a couple turns prior he actually wanted to do so but got sideways out of Ralph's camera. He up'd a video from his car.) He did say the Hellcat was torching him on the straights though and just wanted to see what it could do/sound like pulling away down a straight. (I actually know the driver from another forum) Not being a ctsv fanboy since I own one but until I see them on the street and know both drivers, videos like this don't mean a whole lot. With this much power it'll be a driver's car/race. I don't see the gen 3 V coming close in HP to the Hellcat (guessing 600-620 tops) but it will be based off the lighter current ATS platform so it won't be a slouch. I've got 100% certainty the V won't touch the exhaust note of the Hellcat though, that thing is pure intoxication. I do agree, not producing a 300 version is a sad, sad mistake. I'm not a big fan of the Charger and 2 doors on the Chally limits buyers.

Agreed - that vid doesn't prove a thing. At my road course, which is 3 miles around, 20 challenging corners and lots of elevation changes (in short - a driver's track) there are 2 guys up there that run CTS-V's. With one - I'm faster; with the other guy (an instructor ) he usually hands me my ass back on a plate - unless it's raining . . . then I sometimes can beat him.

I ran a lapping day at Calabogie last Saturday. Last chance out before the track closes for winter. It was cold and pissing down rain - lots of standing water. Nobody passed me the entire time - not even 2 911 GT3's. Does that mean I can beat a GT3? No - on a dry track with a decent driver the GT3 will eat me.

I just happen to be a good wet weather driver and the 2 guys with the GT3's didn't want to push as hard.

For me, the bottom line is this: never has there been such a great choice of really good drivers' cars on the market as right now. And the Hellcat seems like the best bargain, at this point in time. I am certain that the Hellcat can be an awesome road course car, and I hope to prove that to be true (if Dodge ever gets around to confirming my order and building my car

All I'm saying is they better wake the freak up and smell the freaking java and reconsider producing the dern 300 version!!! Can you imagine how SWEEEEEEEEEET that thing would look and ride????? Got me spewing in my pants fantasizing about it! :lick: LOL There I go getting my blood pressure up again! :pat:

Spot on as usual!!! I'm young enough that I missed the horsepower wars from the original muscle car era but not so young I can't recall the sad horsepowerless era of the 80s so I am LOVING this recent surge of powerful vehicles. I too wish Dodge would build your beast, as I know you know how to drive and feedback from someone like yourself goes well beyond a random video. My current V is nice (considerably better on the inside and with regard to ride quality/handling than my 07 300 SRT was) but for whatever reason I'm not hooked on it. It's fast (again, faster than my previous car) but it's a bit too tame IMO. There's nothing tame about the Hellcat which I kinda like. :) And like you stated, it really is looking like the best value for the money right now. Get building Dodge, my man here needs to drop some knowledge on us all! :D

First, congrats man!

I thought about it a lot but couldn't give up from my family/self safety. It is Canada and it snows a lot, I am close to you so we almost have the same snow.

As someone who drives least 1 hour everyday in any weather, including an example day of -25C + 10cm snow, I would never pull the trigger for a non-AWD hellcat even I want them as hell.

Unfortunately I don't have luxury to buy a summer car and only drive it in summer but as I always said, if Fiat puts awd in SRT's , they will triple the sales guaranteed! and that will be the day I will buy my first SRT.

But again congrats and drive safe! I am pretty sure that 707hp will make you smile all the time!
