The 6.4 has 10.9 to 1 compression, (390 cu in)
the Hellcat has 9.5:1 compression and 11.6 psi supercharging (376 cu in)
a 426 cu in is 6.9 liters and I believe a 440 is 7.2

What is the weight to horsepower ratio for an application? (Same Body?)
ReplyDeletewhat is the what? Dude, I haven't had any coffee yet this morning, and you are killing me! The HP to weight ratio, for what application? Re-read your question please... and then dumb it down for me for pity's sake! Are you asking the hp to weight for the Hellcat engine vs the 6.4 hemi, for the 2015 Challenger?
