This is an article that, is so simple that you would assume it's been done a dozen times before, but after searching the web over and over, I've had zero luck finding anything. I'd like to see a back-to-back comparison of a Performer RPM (air gap?), Victor Jr, and Weiand Xcelerator on a ~400hp sbf. Dyno runs (rear wheel or engine) that cover 3000-7000rpm would be ideal, as it would show where each intake shines. I think this would be a great article because there are SO MANY of us running 289/302/331/347s that are in the 350-450hp realm, which is right in the grey area of "should I run a single plane or dual plane?". I think the ideal test would be rear-wheel dyno of a manual transmission car, with a 302 or 331, 230ish camshaft, moderate aftermarket heads like AFR 165/185 or similar, 650 carb, and a free flowing full exhaust system. For me personally, this would really answer the question of what I'm giving up/gaining with a medium rise single plane vs. the high-rise Vic Jr., and also what affect switching to a high-rise dual-plane would have. Another interesting thing to try (if time allowed) would be comparing a 650 carb vs. a 750 carb on the dual plane vs. the single plane. I think the dual plane would see a lot greater gain than the single plane, but it would be cool to see the real world difference. Is there any chance that FM would be interested in putting something like this together? Even though it's a little on the higher-hp side, the 347 used in the "Dyno Duel" AFR165 Comp. article would work well as a test bed, and it has already been tested with the Xcelerator intake.
