Boost source? Options

[bob91403]

Could someone tell me why this wouldn't work? This unit gives 7lbs of thrust. If you could flip a switch and go from NA to an extra 7lbs of air pressure, would a fuel injection system be able to adjust by itself?

That thing will prolly produce about 1 psi max of actual intake manifold boost at full throttle. Axial fans are designed to produce a great deal of flow but stall easily when up against backpressure. that is why real compressors (for turbos and superchargers) are designed to be either very high speed centrifugal or positive displacement.
Yes, the stock D-jet fuel injection can handle that small amount assuming it is tuned correctly and functioning as designed. You may or may not be able to tell if there is any horsepower increase by seat of the pants. It will be a very, very small gain.
If you could get it to produce 4 psi of boost in the intake manifold you would be getting close the threshold of what the stock fuel injection can handle without modifications.
