cleaning up the slant six head

1930, Here is a photo of a cold air intake setup that cost a whopping $10(less the price of the filter.) The tube is run thru the rad support to behind the grille. With this one modification the car picked up 4/10ths in the 1/4 mile. Cheap ram air that works.

A few short years ago Hot Rod Magazine did a article where they hooked up a leaf blower to the air intake and made a few passes. It looked silly but proved the principal,,poor man's blow thru turbo.
