Just what was SV actually asking? The responses from you two gentlemen are both accurate and very well stated, but is SV asking about actual HP, BHP, or acceleration?

One of the factors affecting acceleration of diesel engines is the fact that no one to date has produced a "perfect" automatic transmission for diesel engines.

In a previous thread patsy posted a copy of an article about a new company that was developing a "constant speed" automatic transmission that would be the closest to an ideal for use with diesel engines.

In commercial diesel applications, there are a number of factors that influence both the speed and torque of a given vehicle when using a manual transmission. Those are: displacement of the motor, efficiency of the motor, where the horsepower is rated (Cummins and Detriot both take HP ratings at the flywheel, and Caterpillar uses the final drive application), the gearing (ratios) of the transmission, and finally, the gearing (ratios) of the differential.

So, SV, Just what did you want to know again?
