how many cubic inches is the dodge hellcat engine
Chrysler Hemi engine For 2015, Chrysler introduced an all-new high performance supercharged variant of the Hemi engine, called the Hellcat (named after the Grumman F6F Hellcat).[24] It features the same 4.09 in (103.9 mm) bore as the 6.4 L Hemi and the same 3.578 in (90.9 mm) stroke as the 5.7 L, giving it a total displacement of 6,166 cc (6.2 L; 376.3 cu in).[24] The supercharger is a 2,380 cc (145 cu in) twin-screw IHI unit with integrated charge coolers, capable of producing 11.6 psi (80 kPa; 0.80 bar) of boost.[25] This engine is rated at 707 bhp (717 PS; 527 kW) @ 6,000 rpm and 650 lb⋅ft (881 N⋅m) @ 4,000 rpm of torque[24] and has a compression ratio of 9.5:1.[24] This engine was the most powerful engine produced by Chrysler as well as the most powerful production engine ever in a muscle car until the Dodge Demon was introduced.[25] This engine is not equipped with Chrysler's Multi-Displacement System.[25] In 2017, Mopar announced that it would sell it as a crate engine under the name Hellcrate.[26]
Jeep Grand Cherokee The new Grand Cherokee SRT8, which started production on July 16, 2011,[21] is equipped with a 470 hp (350 kW; 480 PS) 6.4 L Hemi V8 engine. Jeep claims the new SRT8 gets 13 percent better fuel economy than its predecessor.[citation needed] To keep the gas mileage respectable,[clarification needed] Jeep has employed a new active exhaust system that lets Chrysler's cylinder-deactivating Fuel Saver Technology operate over a wider rpm band. Chrysler claims that with the larger gas tank, the SUV can now travel up to 500 miles (800 km) on a single tank, while other sources estimate range to be 450 miles (720 km).
