I am guessing you have not see much of my work.
Of course it was still fully installed. The radiator was out of my truck, the fans and shrouds came out with the radiator (the A/C condenser has been gone since 2008) so there was nothing in front of the accessories. I had plenty of room to finely run a P/S system power consumption test. A test that a lot of people have thought about and indirectly tested but never really proven.
With this test I did not care about how much added power it took for the P/S system to turn the wheels with the vehicle sitting still.
The point was to figure out how much of a load the P/S pump put on the engine while a car was rolling along down the open road, a situation where most people would agree the P/S system is not needed.
