[QUOTE="CedarRiverScooter, post: 434252, member: 15465"] I had same problem, solved it by extending the inlet ramp about 4 foot fwd. Made it as smooth as possible. Any steps set up turbulence & feed air to the pump. Other guys have made a hump, which is where the spoon moniker comes from. I would just pop rivet your choice of spoon panel on, then weld it solid after you know it works. It's definitely black art. Edit - Rivets were a bad suggestion, maybe try gluing the prototype panel on with locktite S6 roofing adhesive, good stuff for $5 a tube. [/QUOTE]
