Trying to explain numbers and physics to some people... Sheesh
By definition, Nitrous CAN NOT be FI. You are not compressing the cylinders with NO2. There may be 1000psi at the bottle but you are relieving that pressure into an open air stream that gets drawn into the cylinder at effectively 0psi. You would need a turbocharger or supercharger to COMPRESS the cylinder volume. The argument of effective pressure and chemical reactions has no part in this equation.
Strap a leaf blower on your throttle body, its got to build boost right? Wrong. It may flow 300cfm, but its not compressing air in the cylinders. Youll never see 1psi by doing so.
Here is a real world test to confirm this "theory" into fact. Install an analog vacuum/boost gauge on your nitrous equipped car. You will see tons of fluctuation in vacuum from 20-0in/hg but you will never build positive pressure on the boost side of the gauge.
As for the 300hp NA motor, where is Chris? @
celek Heres a link to build that he currently working on. Its quite impressive.
