Sure there is. JPI has one in their engine monitors. There are others.
I suppose it depends on what you mean by "direct measure".
Power delivered by a rotating shaft is RPM * Torque. RPM is easy to
measure directly, torque is somewhat more difficult. In any case, the JPI
gizmo doesn't measure torque. It measures manifold pressure, and fuel
flow, and intake air temperature, and maybe a few other things, and
computes how much power the engine must be delivering based on those
inputs. That's not quite the same thing as measuring the output directly.
I'm not saying that what the JPI does isn't useful. Just that it doesn't
fit my definition of "direct measure".
As long as it's accurate, who cares?
