Yeah nobody can prove it here either, at least alot of people have seen this thread now and when they hear someone say 600HP is the limit they will know it is only a "myth" that has been busted!
On another note, how much does your Dakota weigh??
It was around 4800 with me in it. Those 3rd gen pigs were really heavy. Especially the 4x4 club cab trucks. That's what I was racing for a bit until I killed the trans and bought a Dart instead. LOL!
