i have been following a thread elsewhere in this furum about how much hp it takes to spin a pump at a given rpm. my question is this: if i have a panther pump that won't spin a whole lot of rpm anyways, why wouldn't the torque number be more important to me than HP?
at the lower rpm's, the torque is doing the work. at least that is how i was taught when building engines. if you look at the graph of a dyno pull, the torque curve and hp curve intersect at some point. anything to the left of that point represents torque working, and anything to the right represents the hp working. i am by no means an expert, but this is how i was taught.
