The pistons are also cast for the 5.7L, along with the same shallow ring lands on all hemis save the Hellcat. The 6.1L and 6.4L SRT Hemis also come with forged crankshafts, the 5.7L is cast. The 5.7L is the least built of the Hemi engines, and the least able to take boost. The shallow ring lands are the biggest culprit, they blow out under
41. The tune that I received with the supercharger lowered the voltage some. Then, I lowered it some more which actually seemed to help with the light throttle/boost situation at cruising speeds. But, I'd rather set the voltage back to stock and tune the throttle pedal. At sea level, a naturally aspirated engine operates at 14.7 psi of atmospheric pressure, and in theory, adding 7 psi of boost will yield an almost 50 percent gain in power. One apparent drawback of supercharging as compared with turbocharging is the fact of engine drag. Because a supercharger is essentially an air compressor, and it’sEdelbrock Gen III 426 HEMI E-Force Supercharged Long Block Crate Engines 46126 Crate Engine, 426 C.I.D. 808 HP, Gen III HEMI, DP3C TVS2650 Supercharged, With Accessories, Assembled, Chrysler, Dodge, Eac
Lower boost blower kits are designed to work within the car's standard equipment, like this: 2010-2006 Charger R/T (5.7) | ProCharger. With an advertised 110 hp jump (340 + 110 = 450), this is short of your stated performance goal mainly because of the two biggest limiting factors, your stock heads and intake manifold.
