A Detroit 2 cycle fires twice as many cylinders per per revolution as a comparable 4 cycle engine,so they sound as if they have twice as many cylinders or run twice as fast. Between the mechanical scream of the roots type blower and the fact that they fire every cylinder every revolution,they truly are a screaming Jimmy.
I once sold a tractor powered by a 6-71 Detroit to an old fellow who had run nothing but a D4 cat before. He was used to a 4 cycle,4 cylinder cat at 1100 rpm making it's slow chukata chukata exhaust noise. I got the old fellow up into the cab,and when he advanced the throttle from 500 rpm idle to around 1000 rpm, the Detriot let out a normal brrrroooowwwww noise. The old guy instantly stiffened up and yanked the throttle back to idle. His wide eyed question to me was "why does that engine run so fast ?" I had to convince him that the engine wasn't really running fast,but sounded that way becuse it was a 6 cyl 2 cycle engine. Even had to get him down to the front of the engine so he could see that the front pully was turning so slow you could almost count revolutions while the exhaust was making the Brrrrrrrrrrrrrrr sound. He ran the tractor for years,but I don't know if he could ever bring himself to run that engine at the 1900 rpm it needed to pull and stand up. His tillage tools were much too small for this 240 hp four wd tractor,so lugging it a bit may not have hurt it.
