I doubt the computer fan blades are what you want...they are designed to move air gently out of a computer case. The suction fan in a shop vac is quite different, you might see about getting some type of inexpensive vacuum cleaner and taking it apart and seeing if you can adapt the FP motor to it. Consider the RPM that the original motor runs at, though, and see if it's a good match for the FP motor.
