agreed....if the difference between using metering rods, and no rods is so slight...why bother if racing. but you need enough motor to run a Qjet with no secondary metering rods without being too rich. if it's a handicap bracket class, jets with no metering rods would be more consistent, less complex, less can go wrong with fuel just going through a hole, with no hangers, rods, flap tension spring, power piston spring to consider at all.
super stockers don't run fast because they have the best carburetor. they run fast because they have really good chassis setup that hooks, and puts it all to the ground.
take any Super Stocker, and start an unlimited single carburetor class, all other rules being equal, the unlimited class would have aftermarket Holleys, Dominators, etc. and be faster.
let's be honest here. the first thing an honest Qjet builder will tell you is,
you will always make more HP with a Holley, inch for inch.
but the Qjet does a damned good job for what it was, and is.
in the case of SS class racers, that's the carb they have to run,
because of the rule book,
not their carb of choice otherwise.
if Qjets were the best carb made for maximum HP,
NASCAR would have been running Qjets instead of Holleys back when they still ran carbs.
and the GT-40 would have ran a Qjet at LeMans, instead of a Holley, back in the 1960's
