I have always heard that the typical rule of thumb is for gas you really should have 4x the outlet then the inlet.

Next time you are in your car roll down your driver's side window about 4-5 inches. fell that very little air comes in. . . while the window is down roll down the right rear window on the passanger's side the same distance as your driver's side window. then (while watching the road) inch the rear right window down and when you reach about 3x the distance you will actually feel the air move across you head to exit in the rear. . .same principle but different vehicle! I know this for a fact because if i smoke in my wife's car I use that method. . . TRUST ME IT WORKS! Im not in trouble other wise i would have new planes!!!!!


thats my1.5 cents

oh, you can get away with a 1 to 3, but 1 to 4 is recomended
for glow it is typically 1 to 2

thats the other .5 cents
