The latest rumor is that the 2011 6.4 Hemi will have 450 hp. (flywheel). I cranked this number, and others, into an on-line calculator, using 4,400 lbs. (with driver). This is what I came up with:

375 hp= 13.9 sec.
400 hp= 13.6
425 hp= 13.3
450 hp= 13.13
500 hp= 12.67

If the 450 hp number is correct, SRTs with pick up .2 in the quarter.
