A engine dyno measures HP at the "crank" because that is where it
attaches. Pure engine to dyno data.
A rear wheel dyno measures HP at the drive wheels, because you don't
want to remove the engine.
A G-tech is an accelerometer that essentially measures the "thrust" of
your vehicle over a specified duration and uses mathmatical equations to
convert the data to HP.
3 totally different ways to measure "work" done.
Each way is not relative to the next, and should only be used as a
comparison to data which is collected in the same manner.
Comparing a G-tech result with any kind of dyno has no value, and vice
versa.
