One last question, does the S/C work with the factory throttle body? Because I intend on getting a ported one, unless it has its own.A stock Challenger hood will not close with the SC on. I was given a picture of a template for cutting the hood. You will need to fabricate a scoop or buy an aftermarket hood like the Hellcat knock off.
I believe you are right, 12.5 may be one of the quicker NON-TUNED 6.4's. One of the quicker TUNED 6.4s ran 12.17 w/DR's and Hellcat airbox mod. Its posted in tracktalk section.
I agree, the 6.4 is definitely a better choice if you plan on doing races with it (which you probably are if you want that kind of power), unless you want a little less weight on the front wheels, I like going around curves more than straight lines. :wink3:
The 6.4 sounds amazing though.
