I recently received some help regarding questions about pressure at the TB (I am building a 'Ram Air' for my SRI). What I was sent was the following. The author (Funny car tuner) forgot to note what units he is using. I am seeking that info. Thanks (Yes I am trying to learn this subject [xx(] )


Air Press Drop Equivalent Pressure Pressure
Flow / 100 feet Feet at
CFM carburator

0 0 10 1.77 1.77
50 0.675 10 1.77 1.70
100 2.7 10 1.77 1.50
200 10.8 10 1.77 0.69
400 43 10 1.77 2.53
800 173 10 1.77 15.53

60 MPH = 1.77" ( << It's in inches. Inches of what?)
