a different Dynamic pressure calculator
at 60 MPH /88 FPS yields 0.043 PSI *theoretical* Boost to air box
Dynamic Pressure
my scoop in a high pressure area Air Dam
my experience has been that the cheap alum. hose is *blown * to bits over time
when time and energy permits i hope to fabricate a U Tube Manometer
and try to measure actual pressure differentials at various locations in the induction path.
U-Tube Manometer
while this DIY manometer is for use calculating propane tank pressures i think it would work .
at 120 MPH one would expect less than 5 INO2 pressure .17 PSI differential
my operating speeds are 60-70 MPH Max. expect 1.2 INO2 at 60 MPH.
