I'm getting ready to mount my new motors. My plan is to mount 4 on one switch, then two on another, and again two on another. The 4 motors that are on seperate switches, I'm going to put a flapper valve on. I'm going to use the 6" PVC idea. My question:
The motors have mounting holes in the plastic. I'm thinking of putting the motor thru the hole and secure it with the taps on the motors. Will this in any way cause a problem as far as pulling the air? I've always just glued the face to the board with some sort of bar support. This would be so much easier considering the motors are twice as big.
Thanks Guys!!

The original Car Craft Article had the motors mounted that way. I have mounted the motors that way too in a couple of applications. With a double door arrangement that many are using there will be no issues with being able to remove the motor if it goes bad. There will be no airflow issues.

FYI.. If you have a 2-stage type Ametek motor. This is a 116978-07 to be exact, YOU CANNOT MOUNT the motor thru a hole. The exhaust and the intake are on the same side of the motor! The motor exhaust thru louvers on the motor just below the housing. So basically the intake and exhaust are on the same side of the board :angry:

The 115923 Ametec motors (SF type) are two stage motors and will allow the thru mounting.

I'll get a pic Larry
What's the difference between a thru flow and bypass motor? Any help would be appreciated.

Yours are bypass, the flow bypasses the motor. The motor has separate cooling air flow.
A "flow through" flows all the air through the motor.

With a thru flow motor, the air is drawn into the motor and is blown out the back of the motor so that it can cool the electrical parts of the motor, most normal household vacuum cleaners use that type of motor.
With a bypass motor, the air is drawn into the blower and out the side of the blower housing a separate fan is used to provide the cooling air for the motor, a typical application for this type of motor is a wet/dry vacuum cleaner where the working air should not come in contact electrical parts of the motor.
Because a separate fan is used to cool the motor, the airflow can be severely throttled back without overheating the motor so, a bypass motor is also suited for a flowbench, like the original MSD bench, in which the airflow is controlled by restricting the air flow.

Now I see what you have...description threw me off.
Your original motors were mounted on the opposite side of the wall than I have mine. If you now have Pheripheral Discharge Motors, move them to the other side of the plenum divider...they'll be fine.
