Dodge Hemi 392 6.4L Engine Blueprint Illustration Series T-shirt
We've had a few of our Hellcat engine customers ask about the 6.4L engine, so here it is.
Taken from Allpar.com :
The 6.4 Hemi (392 Hemi) is used in the 2011 and newer SRT8 cars including the Jeep Grand Cherokee SRT8. The engine is different from the one in the Challenger Drag Pack (the Mopar crate engine); for one, the standard 392 shuts off four cylinders when they are not needed, to increase gas mileage. The crate and production engines have a different bore, stroke, cam, heads, compression, and intake.
For 2015, power in the Charger and Challenger versions of the 392 was boosted from 470 to 485 horsepower, with torque climbing from 470 to 475 pound-feet (in the Grand Cherokee, power was still 470 hp, 465 pound-feet).
