I have a 4.2 in a Mk2, it’s a 9:1 motor
It’s got a straight port head, 420 log manifold, and 2x HD8s
Due to the very little space between carbs and engine compartment, and the Mk2’s propensity to heat soak, I built an angled air box connected to a flexible hose to an air filter under the fender. The system made a big difference in running condition, but over the years the face of the box has warped (I used too thin steel for the mating surface with the carbs).
I’m remaking the front of the box, and my question is: Right now the carbs are sucking air from an open space. I know runners improve air smoothness etc. I could fit definitely 1/2" of tube, perhaps 1" if I’m creative, inside the box.
Is this worth doing?
