I wish someone would run before and after Dynos on that. Decreased surface area to draw air thru, I spent several hours reading about intake theory, since intake relies on suction, an obstruction is a bigger limiter of air flow through the motor than the same obstruction in the exhaust, because the piston is pumping air passed it.
Optimum intake design has sufficient volume between filter and carb to fill the cylinder. Careful work CAN create a pressure wave standing in the intake just waiting for the intake to open, but that would, unless variable, enhance a small RPM range. The science of intake design has only barely been approached on this forum.. I don't remember what all I learned, but I increased the volume of the air box. I had a Stage one cam, Supertrapp with 14 disks ,jetted carb, Zero to sixty times were ever so close to six seconds and I had not lightened anything. I did use a KN filter but wouldn't again,,, money wasted IMO. I would not spend the money on a Supertrapp, unless someone does dyno runs proving the Trapp IS sufficiently superior to justify. $400.00 vs. $20.00 money for a muffler. Besides, the Trapp is ugly and the Dyna looks good. Of course, dyno runs or timed runs, something besides Seatof the pannts,
