'Rat,
Alright, you found the answer. A B&D Leafblower will do the trick.
They ad them at MPH, 120 MPH, 150 MPH, etc.
Just wonder how many CFM. Pressure doesn't come into it, as if you can feed the intake enough air, it will take it.
Now, problem # 1, you have to start the engine with that obstruction in the intake.
Problem # 2, if the thing puts out more than the engine can handle, what do you do with the excess. As in, an engine that is 10:1 compression is that only with atmospheric pressure, not turbo, unless the turbo does not kick in till the engine starts to starve.
Now, you need to plumb the thing in so that it will give you boost, and not be an obstruction, and still be able to boost when you need it, so you have to engineer a wastegate, for one, and a "check valve" so it doesn't blow all the air back out of the naturally aspirated engine's intake.
What's next?
Cheers,
George
