I've come to "my own conclusion" that stacked pulleys are not made for a 11 second street car. and i also believe that i am accurate in saying that 94% SRT6 owners are NOT dedicated to the drag strip but rather enjoy driving their SRT6 down the street but when approaching any Porsche or SRT8, say "yea im bout to spank that a**". Having said that, i find it VERY hard to believe that the select FEW that are running stacked pulleys (with stock injectors at that!!) dont even go above the posted speed limits, but just like being able to say that they are running stacked pulleys. Im willing to put all chips in saying that stacked pulleys are almost next to impossible to have (on our cars atleast) for a "street car". Its easy to build a drag car. The hardest thing to build is a street car. I believe that if those few that have stacked pulleys ran their car the way the mods were intended to be ran, they might encounter something catastrophic. Otherwise, whats the point?? De-mod and run the car with enjoyment!!!
