"Horsepower = torque x rpm / 5252
so....as horsepower goes up, torque always goes up, or.....rpm goes up"

Interesting concept.

Not necessarily.

HP is a measure of work as a byproduct of torque. If RPM's increase HP will increase if torque remains constant (in theroy). If torque increases, HP may increase but only at RPMs over 5252.

Basically, HP is such a grey area as it is a passive measurement.

Ok - so take 2 motors with identical everything except redline. Motor 1 has a 6500 RPM redline, motor 2 has a 7200 RPM redline - again, identical torque. Motor 2 will have a higher peak HP, even with the same torque, right?

Isn't this just what the J32A1/A2 does?

A1 & A2 are slightly different in architecture. The A2 makes more tq than the A1 due to induction/resonance tuning and other small, but consequential, details. There are 16 lbs/ft more at 5252 as well as 3000-5000 by being more flat. The higher redline (as a result of slightly stronger block & rods) takes advantage of the higher tq #'s.

Look at the dyno charts of each if you can find em.
