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]
Ford Power Stroke engine Emissions controls include exhaust gas recirculation, Denoxtronic-based selective catalytic reduction (SCR) from Bosch, and a DPF. Output was originally 390 hp (291 kW) and 735 lb·ft (997 N·m).[6] but shortly after production started, Ford announced that they made an update to the 6.7L diesel. The new engine control software makes the engine capable of 400 hp (298 kW) at 2,800 rpm and 800 lb·ft (1,085 N·m) at 1,600 rpm while achieving better fuel economy and without any physical changes to the engine. [7] The 2015 engines are rated at 440 horsepower (330 kW) and 860 lb·ft (1,166 N·m).[8] Ford claims the bump in horsepower is from a new turbo, new injector nozzles and exhaust improvements. For 2017, the torque has risen to 925 lb·ft (1,254 N·m) at 1800rpm, Horsepower remains the same..[9]
