I think what we forget is that it is possible to make an electric supercharger work on extremely small displacement motors. Any engine that you can feel a different level of strain from each fan speed with and without the drag of A/C, it may be very possible to increase flow with a little fan.
Not saying that it will have the numbers that it says, but I've seen stranger things happen.
Now if I could only figure out where to strap it onto my 46.
