Re: detroit diesel 6v71 sound
I like the 6-71T better..... had one in my old fire truck. Once you get up to highway speed you just kind of play the pedal a touch by listening to the whine of the turbo (through your ear muffs that you have to wear, sitting in front of the engine!). Could not just put a brick on the pedal, because it could go faster than the speed limit and stay under redline (it was NOT the original motor - that truck had some legs!).
