hello how is the kpa going up on dyno is it the eddy currunt or some air fan ???
The dyno can hold the same speed regardless of engine load (manifold pressure measured in kPa). This is called a "Load Bearing Dyno", as opposed to the "Inertial Dyno" that just measures the time it takes to accelerate a known mass, but can't hold a fixed speed.
thanx for the fast responde
