Ed,
Help me understand your assertion. How can this be true if the gasser develops its 400 foot pounds of torque at 5000 rpm and the diesel 800 foot pounds at 2000 rpms. Aren't both engines putting out their MAXIMUM power just at different speeds? It makes no sense to me that you can say because the gasser is turning twice as fast it effectivelky makes the same power as the diesel. Doesn't it make half the power of the diesel turning twice as fast? Can you explain your logic better as your premise just does not seem correct. Also, real world driving as in seat of the pants stuff does not provide support for your position. I understand reduction gears but this is not about reduction gears as both engines go through the transmission and to the final drive (4.10, 3.73 or whatever). Essentially the transmissions and final drives are nearly the same in gearing gas or diesel. So where is the reduction gearing at 2:1 ratio in the drivetrain? Also, the towing guides provided by the manufacturers tend to differentiate between the diesel and gasser and if the reduction gearing was causing both engines to be putting out essentially the same power, why not reflect that in the tow guides. How can they both be putting out the same power to the wheels?
Reduction at the transmission, a gasser will use 1st/2nd at 4000+ where the diesel will be in 3rd/4th at 1800-2000.
