If I close
1. inlet of the compressor
2. outlet of the compressor
3. inlet of the blower fan
4. outlet of the blower fan
will the current of the driving motor increase or decrease?
This is the argument which I have with my friend.I said current increase but my friend said decrease.
Can someone be a judge.
Thanks

Additional details: The driving motor means electrical induction motor.
There is no connection between compressor and blower fan they are totally separate systems.

you will be asking the motor to supply more power, thus the motor speed will increase with the load.
i am not an electrician, nor an engineer, however, i did stay at a holiday inn express last night!

1 and 3 will reduce the load on the motor and it will speed up. It has less work to do since no air is moving through the fan or compressor. Try it with a vacuum cleaner: block the suction tube and you'll hear the motor speed up.
2 will definitely increase the load and slow or stall the motor.
4 may either increase or decrease the load depending on the blower type. See the ref.

Maybe it's me, but I don't clearly understand the question and I have to assume too much to answer this question. What kind of motor (electro, diesel, constant rpm or variable rpm governor), are the compressor and blower from a turbo, what do you mean by "driving motor" (to start the engine or is it a power take off)? Do you want to start the engine with the closed manifold or is it already running when you close it?
Maybe you can tell some more?
Additional details:
I still can't imagine the configuration, I'm sorry.

If you close the inlet of the motor driven compressor the current will increase, this is because the motor would still try to suck as much as it can, it will lower its speed then to gain the running speed the starting winding will help the running winding to attain it.
If you close the inlet of the motor driven compressor, it will also increase the current. This is because the it would still try to compress as much as he can thus needed torque to be coupled by the starting winding of the motor.

Why not do the test and figure it out your self. Then let everybody know the answer.
