One-off Challenger Hellcat X announced

What's missing from the Hellcat? Two turbos and about 100hp...



This car is a one-off, so don't get too excited. For the 2015 Dream Giveaway, an American charity competition that really does live up to the name, one of the prizes is a Challenger Hellcat. Not just any Hellcat either, but a Hellcat X.

Who wants just 707hp when there's 805?
Who wants just 707hp when there's 805?
The Hellcat X adds two turbos to the 6.2-litre supercharged V8, taking power from 707hp to 805 (!), with torque now rated at 800lb ft. Think about that for a second. Two turbochargers and a supercharger on a 6.2-litre V8. The turbos are 62mm Hellion Power System items, with the work undertaken by Walsh Motorsports. It's not an official Dodge product. No performance claims have been released but you would have to think this is the upgrade to take the Hellcat through 200mph.

The car is named after the US Navy's XF6F Hellcat fighter, which was also super- and turbocharged. Apparently the production version achieved a 19:1 kill ratio in WWII. In case it wasn't menacing enough...

The aircraft influence continues outside with the aluminium 'hood extractors' (or bonnet vents as they should be known) with a central scoop, front chin spoiler and adjustable rear wing also. How closely related to actual aviation these are is unknown but, well, would you argue with it?

You thinking what we're thinking?

The Dream Giveaway competition gets better too, with the Challenger prize also including a magnificent 1970 R/T 440. Manual. And $40,000 for taxes. All for three dollars. If that doesn't take your fancy there's a Corvette and a Mustang pair too...

Finally, about this one-off thing. The very prospect of a 707hp muscle car (and saloon!) was silly enough, so just finding another 14 per cent more power isn't that ridiculous. An official limited edition perhaps? Go on Dodge, you know you want to...

Watch the video here (caution: very American)

Makes you wonder why they went for the twin set up on the turbo. Cant imagine with only increasing by 100bhp and having a big SC V8 it would suffer with lag.

Bet it sounds epic at full chat.

The video is tasteless -- the product of a confused mind.

The video reads like a passage from Snow Crash. So jingoistic it almost veers into parody.

The Deliverator's car has enough potential energy packed into its batteries to fire a pound of bacon into the Asteroid Belt. Unlike a bimbo box or a Burb beater, the Deliverator's car unloads that power through gaping, gleaming, polished sphincters... You want to talk contact patches? Your car's tires have tiny contact patches, talk to the asphalt in four places the size of your tongue. The Deliverator's car has big sticky tires with contact patches the size of a fat lady's thighs. The Deliverator is in touch with the road, starts like a bad day, stops on a peseta.

“The Deliverator belongs to an elite order, a hallow subcategory. He's got esprit up to here. Right now, he is preparing to carry out his third mission of the night. His uniform is black as activated charcoal, filtering the very light out of the air. A bullet will bounce off its arachnofiber weave like a wren hitting a patio door, but excess perspiration wafts through it like a breeze through a freshly napalmed forest. Where his body has bony extremities, the suit has sintered armorgel: feels like gritty jello, protects like a stack of telephone books.”

Not sure why a supercharger and TT, why not just strip out the S/C and go twin turbo. Seem an awful lot of extra complexity when the same result could have been achieved with half the bolt on plumbing

Turn the sound down the pics are nice. One of the great last piston fighters. Double wasp engine 2000 hp I think.

Why not just turn the supercharger up?

I'm guessing their at the limit of the S/C setup

Needs a roof rack to carry spare pair of back tyres for when you toast them after a 100 miles.

I would be massively surprised if that were the case.

Well seems a strange choice to go with more bolt on, if a pulley change would have done the same thing

Hmm, wonder if that might work in a bar.. "Hey Lady, how you doin'? My name is Ben and I have exceptionalism".

Actually, maybe not, sounds like a disability.

I think mainly "Because Twin Turbo" probably sums it up.

What limit? They're obviously not at the limit of stuffing more air into the cylinders, as that is what the turbos are doing.

Potentially at the limit of the intercooler, not sure what supercharger they use though. I know more about the LS engines which are very easy to boost to higher powers than this with the stock charger on the LSA.

Do they have an intercooler? It looks like the supercharger just sits in the V.

The LSA has an air to water IC below the rotors, not sure if the Dodge uses the Eaton TVS as well.

The turbo supercharger idea is an obvious "because we can" no other reason. It would as others have suggested be simpler to just go twin turbo or put a larger blower or a smaller pulley (if the blower has spare capacity) on.

There is also the link to the Hellcat and the turbo-supercharging of its engine. But either way its great to see mentalism like this still exists in a world of bland eco-boxes and corporate clap-trap biggrin

I imagine it will be the same as the bolt on chargers for the Mustangs, they have an air-water intercooler between the blower outlet and the manifold, with an additional radiator at the front to cool the coolant.

Ah, I see, makes sense. I did wonder how they dealt with heat in that sort of setup.
