Yeah, I figured the restriction would only kill power... our meters aren't hotwires? If they are, flow rmass is based on flow rate over the wire, which is very much affected by diameter, although the section before the MAF wouldn't have changed, so voltage readings should still reflect OEM scaling. Of course, abrupt transitions can throw things off... a problem I sort of hoped would not come up, but who knows until I try. Anywho... I ordered a different set which should definitely have a smooth transition from bellmouth to the OEM diameter, so we'll see how that goes. That was the original plan -- I had a set! But, after deciding that fabricating decent airboxes for them would be too much of a PITA (I have zero experience working with fiberglass...), I sold them off and have started this new project using intact (but separated into F & R halves) OEM airboxes. On that note, I have some fiberglass repair kits I should just probably sell off...
