Hello,
I managed to place my hands on a G probe (acceleration probe) that I can
connect to my calculator to gather information.
Now, the question is: how do I use this to calculate the horsepower of my car
:-)
1 horse power is equal to:
745.7 kg * m2 / s^3
1 g is equal to 9.81 m / s2
The car is 1088 kg (2400 lbs * 0.4536)
I can get the speed of my car out of the tacho knowing that 1mph = .447m/s (or
by integrating the acceleration curve)
So, can I assume that the following equation will give me my engine horsepower
at any given time:
Power = (probe_output*9.81 m/s2 * 1088 kg * current_speed * 477 m/s) / 745.7 ?
(knowing of course that this value does not take into account external and
internal frictions such as air friction, alternator, drive train... (note that
the air pump is not here :-) ).
Interesting problem, isn't it?
