You're all smoking something. You can not make boost with a tuned intake runner. The best you can do is minimize flow losses. If you improve flow loss from 75% to 90%, you haven't made 15% of boost, you've improved flow.

Did the math , did extensive R & D on this one, months of work with tubes,elbows, different filters. Have a huge box of hoses ,tubes filters,clamps. Found out where you have a gain you have a loss ,was able to to move my mid range around somewhat but at the same time I would lose some power of the line(where I like power) or was unable to get to that last 7 or 8 mph on top cause I had a killer midrange tuned too low in the rpm range. At one point I had it  close but tubes duct taped to bike and air filter way too the rear wasn't going to stay,think I had gone to a additional bounce the pressure wave. It was fun and educational but the work did not equal the gain. A good cam or vm36 with UFO , Quad flow wing  , Intelajet will get you a better midrange punch. Not worth the time and effort for minimal gains !

At the risk of getting Versy upset and only he can say what's true. He came up with a cool dual filter intake , but I not so sure it had ram induction in mind when it was made and I'm pretty sure he's got a 40 or 42 mm Harley carb on it that needs the extra air intake flow.
So do tell Versy, inquiring minds want to know !
I think my next build ,if it winds up being a savage engine, I won't hold back I will pull out all the stops. And then ....................................

Yes sometimes we acquire parts and sometimes a miracle happens , it all works perfect together. I thought I remembered you saying something like that before. If it wasn't for that RYCA battery box I would have moved the carb further away from the engine and a straight hose back to as huge foam air filter that way the engine would continue to suck the money directly from my wallet !!!

Ruttly,i'm running a stock motor,my only mods being ,spacer and rejetting of the carb,and a Dyna muffler.I've got a hold of a spare stock air box and side covers,and am gutting the box and using 2" pvc right off the stock rubber hose into a 90 elbow and small extension(length to be determined) in the neighborhood of18" .Air filters to be moved to the areas of the side covers which will end up twice as deep ,but the bike  will remain fairly stock looking (sleeper) 4% rise in EV should occur at 3877rpm-61 mph to 4336rpm-68mph,(superslab speed in N.Y. being 65).7% rise in EV should occur at4973rpm-78mph to 5683rpm-89mph in passing mode.I'm not looking for higher speeds as the bike will already do 90,I'm looking for more power to build speed on on ramps .to be able to pass a bit faster if need be and to have a bit more power as I am riding two up most of the time.the speeds above are 5th gear,being in4th would decease them by 4mph.

Ruttly ,yes ,have planed to do that,I've also thought about shortening the exhaust header slightly(less than an inch) as that favors higher rpms.
