those trucks are pretty fast seem them at the strip!

 

Those turbo diesel trucks can be crazy. My first race with the supercharger was against a big yellow turbo diesel truck on the interstate. We went 70-130. Up til 120 we were dead even, after that I started inching on him really slow. Once we shut down I looked over at him and he had the exact same "WTF just happend" look on his face that I did. I'd love to know what kinda power that thing was making to keep up with a 300whp S2000, haha

 

I ran my friends dodge diesel in my C55. I had a full load of passengers (800+lbs) and he would pull me on hw runs. From 30 I pulled a bit and he didn't catch up but I was in no way running away from him. I think he's running 5x psi on a 70mm turbo. It's crazy to see those things go so quick!
