Dodge Hellcat HEMI V8 Details Revealed

Dodge Hellcat HEMI V8 Details Revealed

The most powerful V8 ever produced by Dodge is going to fit into the new Challenger SRT Hellcat, a few more details on which have been released by the brand. 

The supercharged 6.2-liter V8 is going to make more than 600 hp, and will be hooked up to either a six-speed manual or an eight-speed automatic. A unique water jacket to help with cooling and a forged-steel crankshaft that can withstand firing pressures up to 1,595 psi are just two of the things that set this motor apart, and Chrysler says it shares just 9 percent of its components with Dodge’s 6.4-liter V8.

High-strength, forged-alloy pistons are also used in the motor hooked up to powder-forged connecting rods with high load-capacity bushings and diamond-like carbon-coated piston pins. High strength materials continue with the heat-treated aluminum-alloy cylinder heads.2015-Challenger-HellCat-Hemi-Main

When it comes to the supercharger, it is a twin-screw setup that has a drive ratio of 2.36:1 and a maximum speed of 14,600 rpm. Boost pressure goes to maximum of 11.6 psi from the 2.4-liter blower that uses integral charge coolers and an integrated electronic bypass. Also unique on this car is an exclusive air inlet port built into the driver-side parking lamp that feeds air directly to the air box.

For the fuel system, an in-tank pump that accommodates variable pressures is used along with half-inch fuel lines and eight high-flow injectors. All said, if the engine is pinned at full power it will use up all the gas in its 18.5-gallon tank in just 13 minutes.

Power is sent to the rear-wheels of the car, where an asymmetric limited-slip differential is found. It allows for unique bias-ratio tuning specifically for the race track to allow smooth power delivery for maximum acceleration. The 230-mm rear axle is made from lightweight materials and used new cooling fins, low-viscosity fluid and specially designed bearing to help improve efficiency.

Getting the power to the road are P275/40ZR20 Pirelli P Zero Nero tires wrapped around 20 x 9.5-inch, lightweight forged-aluminum wheels with a matte black finish. Brakes in the front use 15.4-inch Brembo two piece rotors with a six-piston caliper.

Also to help on the racetrack, a full aerodynamic kit is used on this car that includes a new front fascia with a splitter along with a larger rear spoiler. Supercharged badges set this car apart from lesser Challengers and complete the look.

    I LOVE this car, but these tires have to GO! Come on….. 275/40/20’s are WHIMPY! That’s what I HAD on my 2007 SRT8 Charger and those things would go up in smoke at any speed below 30mph WITHOUT doing anything except stabbing the throttle. I now have 295/35/20’s and they barely keep it hooked up under 30mph and you better be going perfectly straight when the trans shifts from 1st to 2nd or those 295’s go up in smoke. I’m only making about 450hp at the crank. This Hellcat is supposed to up that by at least 150HP. Do everyone a favor and fit some Viper sized 315’s in the back so this thing will hook up.
