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.

The supercharger will work wonders. My E55 is over 4200lbs and it makes huge torque with the supercharger. The E55 is said to run in the low 11's with 0-60 of 4.2secs.
The big problem with that much torque is hooking up the tires. It will keep them spinning well into 3rd gear.
