Sonic helix bore

Some members claim to have dyno gains of ~9hp/13ft-lbs with the spacer. Personally, I believe it's the fact that plenum volume is being increased and not so much the "swirls" in the spacer. I'm thinking about having my swirls milled out (happen to have an old spacer that will fit) so that I don't have the wooshing sound.
