The car runs a 13.2 quarter mile @105 MP/h stock, my goal is to get it down to a 10 second car.

I've seen a few twin turbo setups on Challengers, and they absolutely fly after the 300' mark, but they're still sluggish off the line. A friend of mine down in the states is running twin superchargers on his 440 Stroker and he's pulling mid 9's.
