Nice rig, but the dual airbox mod confuses me.
Are there really only those (12) ~1" perforated air inlets (on snorkel box) feeding air to your Engine? So (12) x 1" holes covered 50% by perforations...doing the reverse math...the flow area of those (12) perforated inlets is equivalent to a single 2.45" ID inlet pipe.
Area of 1" hole = 0.785 in2
Perforated hole area (assumed 50%) = 0.393 in2
Sum Area of (12) inlets = 4.71 in2
Use Area formula A=Pi*r*r and reverse calc for diameter where A = 4.71 in2...r = 1.225", so D = 2.45".
good point, yes it could be better. not my design but i went with it. I was thinking about cutting out the whole front of the snorkel, didn't have or couldn't find the right type of screen and pre-filter to put there at the time. however, since were assuming lets assume it 3" id. whats the id of the carb intake? 1.25? i don't really know. now take in affect your going 15 to 60 mph, its no longer air trying to be sucked in, its air being forced in it. When the piston goes down the only air it gets is whats in the box. just adding that second hose alone gives the piston a little more air to suck in. But I could be wrong. this odyssey wouldn't be where it is at now without the advice and tips i have gotten from reading and reviewing all the post here. you guys are great. The best thing to do is to buy it, and add your modification to it. :) :) :)
