What is the fastest Hemi?
1st Place: 1970 Plymouth 'Cuda
The fastest street Hemi on this list is the 1970 Plymouth Hemi Cuda with a 13.10-second quarter-mile, traveling at 107.1 miles per hour (Car Craft, November 1969), and was also the fastest muscle car of 1970.
Aluminum 572 Hemi Long Block
This Gen II Hemi features an aluminum block and cylinder heads for some major weight savings. A solid roller camshaft and shaft mounted roller rockers boost reliability on this 700 HP power plant.
Chrysler's Biggest Hemi: 10 Feet Long, 16 Cylinders, and 2220 Cubic Inches! A key step in the development of the famous Chrysler Hemi V8 was this monster: a 2500-horsepower aircraft engine designed for the U.S. armed forces in World War II.
The ultimate evolution of the modern Hemi engine is the 6.2L Hellcat V8. This supercharged monstrosity has been tuned to produce between 707 hp and 840 hp over its near-decade on the market, with torque peaking at a terrific 650 lb-ft.
The car was literally built around that extraordinary V12 HEMI, and the mechanics of the car are as remarkable as the rest. Case in point: a custom-built Turbo 400 transmission and a hand-fabricated fuel-injection system with 12 Weber carbs turned into throttle bodies for easy starting and idling.
These immensely powerful cars use the 6.2-liter Hemi V8 engine that produces 717 hp in the Hellcat and 808 hp in the SRT Demon, so the Demon is much faster than the Hellcat.

The Hellephant crate engine was introduced in 2018 by MOPAR when the company showcased it through the 1968 Dodge Charger restomod. This model was later considered the ultimate combination of MOPAR's two unique creations in engine power —the Hellcat and the Elephant.
How fast is a Dodge Hellephant?
David says it can hit a top speed of 170 mph, something we're sure he's only tried out on the track because he doesn't want to lose such a wonderful machine. Nicknamed the Dumbo Charger, this thing wears blue Hellephant logos as the only warning of what's going on under the hood.
"What you're seeing here is a 572-cubic-inch Hemi (that's 9.4L) that utilizes twin NRE 88mm turbochargers, twin intercoolers, and a computer-controlled dual-injection system that switches automatically between 91 and 116 octane fuel when the octane threshold is reached."
6.4L Heavy-Duty HEMI® V8
Getting its name from the hemispherical combustion chambers found atop each cylinder head, the HEMI® uses variable-cam timing (VCT) and boasts 410 horsepower and 429 lb. -ft. of torque. It has a maximum payload of 4,050 lbs.
A HEMI® engine is composed of a hemispherical combustion chamber with dome shaped cylinders and matching piston tops. This creates less surface area than traditional engine which means that less heat and energy lost, and more power is produced.
Here Comes the Hurricane: This 500HP+ Twin Turbo Inline Six is the Replacement for the Hemi V8.
The 6.2L HEMI SRT Demon V8 Engine is not just a suped-up Hellcat Engine - it's its own breed. The new Challenger SRT Demon is the most powerful muscle car on the road thanks to the 6.2-liter Hemi Demon V8 engine that creates 840 horsepower and 700 pound-feet of torque.
Whereas, a V8 means an 8-cylinder engine. But, you may wonder what the 'V' means in V6 and V8. The 'V' represents the way cylinders are arranged in your engine. V-type engines have cylinders placed in a V-like shape, or to put it the other way, in two equal rows.
MAN V14 engines have been installed for example on Explorer Dream and Norwegian Spirit, both of which are powered by four 14V48/60 generating sets producing 14,700 kW (19,700 hp) each.
The Challenger and Charger Hellcat models feature the supercharged 6.2L Hemi engine that gets more than 700 horsepower, which does dwarf the Scatpack's 6.4L Hemi and its 475 horsepower output. These are relative, however: the Scatpack is still speedier than just about anything else on the road.
Well, Mohamed Ahmed Abu-Shlieba thought the Dodge Challenger Hellcat could outrun the cops. Not only was he right about the police cars not being able to keep up, thanks to the Hellcat's top speed of 200-MPH, the helicopters couldn't keep up either. Watch the latest Motorious Podcast here.
Can a Hellcat have 1000 hp?
Thanks to engine mods including an upgraded supercharger, the HPE1000 Hellcat puts out an astounding 1000 hp and 948 lb-ft of torque. This all gets sent to the rear wheels by a six-speed manual transmission. The headers and upgraded supercharger also enable the engine the sound even more visceral than the stock unit.
The Boss 429 engine used a single Holley four-barrel carburetor rated at 735 CFM mounted on an aluminum intake manifold. All these cars had 4-Speed Manual Transmissions and the Boss was rated very conservatively at 375 HP while actual output was believed to be well over 500 horsepower.
Power Numbers: Turbo 5.7L Hemi
Torque production was 400 lb-ft or more from 3,600 rpm to 5,000 rpm. Adding 8 psi of boost upped the power numbers to 571 hp and 619 lb-ft, while 10.4 psi pushed them to 627 hp and 688 lb-ft.
In truth, the 429 SCJ produced more like 425-450 horsepower and 480 lb-ft of torque, more on a par with the big-block Chevy. These numbers demonstrate what you can do with a 429 SCJ stocker.
The sweet spot was found at 32 degrees, where the 496 big-block stroker belted out 709 hp at 6,700 rpm and 602 lb-ft of torque at 5,600 rpm! The torque curve, more of a plateau, rolled in with 579 lb-ft at 4,300 rpm and was still making 546 lb-ft all the way at 6,800 rpm.

Are Dodge ghouls real?
What Is an SRT Ghoul? The SRT Ghoul is not a real car, nor is an SRT Ghoul currently on the drawing board at Dodge. That's the bad news. The SRT Ghoul is a 100-percent fabrication dreamed up by Jay Traugott, a writer at carbuzz.com, as a 2021 April Fool's spoof.
He was able to lay down a quickest time of 9.278 seconds, with a trap speed of 150 mph. That's half a second quicker than a stock Demon, but still a few tenths off Hennessey's own 1000-hosepower Challenger. Seeing as how this is Berge's first run with the car, we bet there's plenty of time to be found.
Unsurprisingly there was a substantial amount of interest in the engine, it was after all the most powerful crate engine ever offered by a major manufacturer. Though the total price in excess of $30,000 isn't exactly pocket change, it is relatively good value for an engine that can reliably produce 1,000 hp.
Ralph Gilles owns one of the coolest Dodge Chargers ever created, but his isn't the only Hellephant-powered model out there.
Direct Connection Hellephant Crate Engine Series
As mentioned above, that engine was called the Hellephant 426 Supercharged Mopar Crate HEMI and with an MSRP of $29,995 and just 100 units produced, it sold out in less than two full days.

Scat Pack Precursor: the SRT 392
SRT was tasked with developing the 392ci "Apache" Hemi—rated initially at 470 hp—as a replacement for the 425hp 6.1-liter Hemi, which was exclusive to SRT vehicles from 2008 to 2010. The 392ci Apache Hemi is considered the defining feature of the 2015-present Dodge Scat Pack.
Can a 6.4 Hemi be supercharged?
ProCharger has increased the power levels with the Stage II Dedicated Drive System and tuner kit for the 6.4L (392) Hemi. The installation of the ProCharger Stage II supercharger can push the horsepower to 800, 900, 1,000, or even over 1,200.
Despite the confusion this might cause among enthusiasts, the 6.4L/392 HEMI engine has basically the same internal parts regardless of if the engine came out of a Challenger/Charger or Durango/Grand Cherokee SRT. The factory horsepower and torque ratings on the 2011 to 2014 engines was 470 hp @ 6,000 rpm and 470 lb.
While Dodge's (and Ram's) supercharged 6.2-litre “Hellcat” V8 will be eliminated at the end of 2023 in a move to comply with tougher emissions regulations, the famous HEMI V8 is here to stay even with the new twin-turbocharged inline six-cylinder engine recently unveiled by Stellantis.
The word "hemi" is a shortening of the word "hemispherical," and as it relates to engines, means a type of engine that has a hemispherically shaped combustion chamber. It's the same thing that is meant in geography when referencing the Earth, which is split into two hemispheres, north and south.
Still considered a small-block engine based on displacement, the 5.7L Gen. III Hemi uses a hemispherical combustion chamber with two spark plugs per cylinder and small wedge flats along with excellent intake and exhaust ports.
The performance level for V8 5.7L, 6.1L and 6.4L 2006-2021 Challengers, Chargers, 300C and Magnum vehicles just got raised. Hellion now produces a “hidden” twin turbo kit capable of anywhere from 500hp to just short of 2000hp.

The 5.7 liter, 345 cid HEMI V8 is the first HEMI designed engine used in 30 years. Making its debut in 2002 in the Dodge Ram 2500 and 3500 models. Since then it has been used in several RWD Chryslers, Dodges and Jeeps such as the 300C, Charger, Challenger, Magnum, Grand Cherokee and Commander.
The SRT 392 engine was specially engineered by Fiat Chrysler's advanced street and racing technology (SRT) team and it's partially named after its 392 cubic-inch engine. The Charger SRT 392 is powered by a 6.4L V8 SRT HEMI MDS engine that generates 485-horsepower and 475 lb-ft of torque.
The Hellephant Name
That's the nickname given to the second-generation Hemi that came out in race-only form in 1964, then in street form in 1966 as the Street Hemi. It got the name "elephant engine" due to its large size, heavy weight, and prodigious ground-pounding power.

6.4-liter HEMI V8 powered by SRT
The 6.4L SRT engine is available on the Dodge Charger and Challenger lineups. This engine produces 485 horsepower and 475 lb-ft of torque and helps the Dodge Charger to accelerate from 0-60 mph in the low four-second range and hit a top speed of 182 mph.
Upgrade it with a 5.7L HEMI supercharger. This is a quick and easy, reliable horsepower boost. Superchargers are a great option to add serious power at a very manageable price tag.
The Hemi first debuted in 1951 and the most renowned of all, the 426 Hemi, was built from 1964 through 1971. Accounts of how many were produced vary, but DiamlerChrysler says 6,671 were built.
The BGE 392 crankshaft forging is the same one used to make the unit in the Hellcat Redeye Hemi—the only difference is in the stroke length and the Hellcat's inclusion of induction-hardened journals. Apache and BGE 392s get a 3.720-inch stroke while the Hellcat Redeye gets a shorter 3.578-inch stroke.
Whats faster Hellcat or Scat Pack?
The Challenger and Charger Hellcat models feature the supercharged 6.2L Hemi engine that gets more than 700 horsepower, which does dwarf the Scatpack's 6.4L Hemi and its 475 horsepower output. These are relative, however: the Scatpack is still speedier than just about anything else on the road.
The Engine Differences
The Scat Pack offers 485 horsepower and 475 lb-ft of torque and provides a quarter-time of 12.40 seconds at a top speed of 115 mph. The Scat Pack is no match versus the 707 horsepower with the SRT Hellcat, which goes through a quarter-mile in just 10.96 seconds.
