Sort of. You can't measure HP, just torque. HP measurement is a simple math calculation based on the torque values found on the dyno.

Because an engine can only rev so high. This is a function of the bore:stroke relationship among other variables.

Close enough.
Books? Can't think of one off hand other than my physics text that needs some dusting off... (Physics 243 in 1983...)
