In my experience, the aluminum dryer duct won't stand the vibration.Andrew
ages ago, I rigged up a spare interior fan (rabbit type) to blow into the n/a diesel air filter box at full throttle. Noticeable difference, and didn't need ram air to be effective. It was good from the get-go. I guess when you're only making 52, a couple extra here and there really are noticeable.
A supercharger you mean... Sounds intriging.
