Thanks to all that responded, much appreciated. The horsepower is pretty easy to achieve with a 5.9 Cummins, 1000 WHP nowadays is pretty achievable, and still be actually streetable to drive everyday. The technology and aftermarket parts are what makes that fairly easy. The cost for a 1000 hp 5.9 Cummins is about $15k, but it will last 100k miles if properly done. The part that worries me is what some of you are saying is a full sized pickup truck is inherently unstable at speed.... hmm, how does a Craftsman NASCAR truck stay stable at 200mph? Aren?t they ?roughly? a full size truck? Granted, they are lowered, have good front and rear spoilers with a tonneau cover, and probably a partial under body pan. All something that is pretty easy to accomplish with my truck. Heck, I bought brand new, and still own, a 2005 Dodge Ram SRT10 truck, stock it was 500hp, I added about 50hp via exhaust, custom ECM tune, and a CAI. At 550hp, it does exactly 160mph before the rev limiter cuts in, with an old style 4spd automatic that is stock, both on the street and on the dyno. Granted, that?s on pavement, but that truck is no way as slippery as my 95 Cummins, just eyeballing the two next to each other. I definitely need to do more research, there is no sense in building an unstable rig. Thanks again to all that responded. Joe
