At this time I think you might be able to get up to about 950hp but with what i know (and thats not much) I think 1000 is out of reach for a single 3.0 charger.
Id be willing to bet some of the more successful 2.5 trucks are over 1k hp.
Man on man i love the way that lbz comes off the line and shifts! sounds so sweet
Ahh Shit ! Man OH Man lol baaaad typo
