You feel it in my truck, especially when the engine fan kicks on 100 percent and my truck has 350hp and 650 ft lbs of torque.
Odd. Does not effect the 158hp idi in my f250. At least I can't feel it.
Lets realize that the nameplate rating, and what the engine is actually producing at a point in time, are different.
Some is related to rotational inertia, some of it is related to how hard/fast the compressor engages.
I wouldnt doubt that there is some unloader valve in some of these, similar to newer easy to start OPE, to help it come on.
Quality and design of compressor, and number of cylinders or other compressor design surely makes a difference too.
