I never understood why these badass old motors lope so bad at idle. but they sound cool as hell.. southern shaker would be proud..

+whb1965 The reason they lope so bad has to do with the port time pressure fuel system, the amount of fuel injected is controlled by a variable pressure valve on the pump and the size of the ports in the injectors, which is somewhat hard to control with precision.While stable in stock form, when the engine is modified, it responds faster than the governor can react. So, say you want 1000 RPM, the governor gives fuel and the engine spikes up to 1200 RPM - so the governor cuts fuel, but then RPMs drop to 800 before the fuel can be reapplied. In affect - gives you that lope.
I spent the better part of 48 years driving Cummins engines and NEVER had a Cummin's idle like that cold after the first 10/15 seconds when all cylinders started hitting, doing what these are doing is governor issue!

GnonplussedGnome it's a overfueling issue lol. I'm sure Luke does take that up the highway like that lol

47 years of driving Cummins engines and NEVER had one with some actual power turned to it .. is what this should say.
