SWEET, we've got the facts from McV, some potential dyno runs and 0-60s, some folks forming decisions on the intake mod they want and some getting pissy over HP stats...I'd say that's a good start for another top mod. for the Shadow. That's the tits!

Well, as I said, not starting a pissin match. Believe what you may. You mentioned fluid dynamics. This is pneumatic dynamics that share the same basic tenets as fluid, acoustic, etc. physics. The hypercharger, as with any cabinet, has a major effect on those dynamics and yes, is proven to be better over a poorly designed intake or bare filter. Also, the design of the K&N filter is superior to a non-specifically designed generic. The ram effect is one facet. The size, directional characteristics, total volume, shape of the cabinet, porting, variable intake baffling, and others are contributing factors in a big way. It could be better but they also have to consider aesthetics. Analogy, Bose speakers are just run of the mill without the cabinet and its specific design. Pipes the same principle. Just as the diameter and reducing/expanding of fluid conduit makes tons of difference in its performance and efficiency. As I also posted, I agree, the Total System from intake to end of exhaust has to be tuned in concert to achieve superiority. Jetting/tuning of the carb, length, diameter, baffling of the exhaust. Even down to the size and length of the tubes running between the bach of the intake cabinet and the carb have effects positive or negative. If the cabinet has no effect, as you postulate, then the jetting wouldn't either. Nor would the changing of pipes. If one follows and is true, all are true as they share the same design principles and dynamics as you say.
Again, not arguing. We are all on the same page here just limited in thoroughness and detail of discussion by this forum/posting medium. As such, sorry I missed your meaning and sarcasm Boris.
Didn't see it at first. My bad. However, I assure you that the hypercharger has as much to do with the total improvement as the K&N does in respect to a OEM filter, as the jetting does to the carb, as the V&H/Cobras/Hardchrome etc pipes do. Physical facts. Arguing this is like the argument that a K&N is no better than an OEM is, well, proven to be wrong. There is plenty of proof (existing dynos by company and individuals as well) if it works on any internal combustion engine, it is the same for a Shadow 750. Unless, that is, it is believed that the Shadow actually defies the basic laws of engineering. That does not make any sense whatsoever.
Also, the exact maximum gain attainable without cracking the engine maybe unknown and yes, doing so can get over 100% gains in HP, but a 20 HP gain on a stock 41-42 HP engine absolutely is indeed attainable. I never said such was possible by air induction alone. That would be just plain stupid to think or say. Sorry for the confusion I guess. But, that's my belief based on facts and extrapolation. Agreeing to disagree is cool with me.
We all agree, otherwise we'd be satisfied with stock pipes, removing the box and duct taping a toilet paper roll stuffed with foam to our carbs.

Thanks for the pics Mcvierh. As soon as my K&N gets here, i'll get started. I'll be sure to post pics here.

How much did you take off Mcvierh, and have you had any issues with rain?

If you are worried about rain than check out this site.

You can buy the material by the foot and stretch it over the openings. Works great.




HitCat, why are you trying to justify the use of a scoop by bringing up acoustics ?
A speaker box is a resonator for sound waves, this would be more relevant if we were discussing the exhaust side.
Anything you place over the carb will be a restriction, how can that be a good thing ?
In motion, I can see a Hypercharger having some affect. Looking at the Mickey Mouse design it would be a negative one until your speed was in the triple digits and you had a way to correct the fuel metering. It ain't an injection hat and these aren't top fuel monsters we are dealing with.
All the magic happens in the carbs venturi and the signal strength it sees. Not in some hokey filter.

Just providing some input on the h/c and the experience i have had with mine.I`ve not had the least bit of trouble with riding in the rain.Talking with Omega(which has a h/c-I meant had)and his would quit if it just drizzled out.Come to find out his float bowl tube was mounted close to the front,where the butterflies helped direct the rain straight into the tube.I installed mine in the rear of the h/c which is protected by the filter.Mel can vouch that we rode(in Tenn.) through one of the biggest and hardest rain i`ve ever been in and not had any trouble and the bike kept humming along.Just thought i`d throw that out there if anyone was curious or thought about putting one on.

^^^ Thats a fact, didn't have to put a rain sock on his h/c at all, and we rode out one of the worst downpours I've ever road in on a bike (I have the BB mod), we rode for miles and miles, cause there wasn't any shelter and all we could do was keep riding till we came out of the storm.

Iíll try one last time. As I said, acoustic, fluid, hydraulic, and yes, pneumatic dynamics share the exact same principles of physics. True, proven, fact. Try putting a fan behind a Bose or similarly superior designed, speaker at the opening of the rear port. The volume will increase. Air is the magic and the porting/design is the medium of efficiency. The same holds true with an internal combustion engine. True, proven, fact. Agreed, a poorly designed cabinet, hampers input, lessens performance/efficiency. Now, the Hyper, which may be Mickey Mouse if thatís your term for a well-designed induction chamber, does the opposite. One reason it is better than an open filter is principle of Surface Tension. The air striking the surface of the filter is repelled naturally by the surface of that filter. A K&N takes this into design attributes and lessens such compared to your supposed Ējust as good genericĒ but can not defeat it. The air moleculesí walls, likewise, naturally repel the filter. Thus, the exchange is not efficient and the majority of those air molecules ďricochetĒ and never enter the system. So, the hyper traps the air funneling it toward the superiorly designed K&N overcoming much more of the surface tension issues. Again, true, proven, fact. The volume of the interior of the hyper, the dimensional ratios, the orientation of the filter within it (centered) all add to this trapping and create the following phenomenon. Add this (blow your mind some more), the material of the hyper, metal, creates more humidity within it than the open atmosphere (as the air molecules rub against the metal creating friction and the temperature variance fluctuates). The damper the air, the more powerful the reaction with the fuel, more efficient burn, more power created. So much more to go into to fully explain the physics of this seemingly simple process but even Iím getting bored with these elementary details. I can trust the engineers and the tests. Besides, then weíd have to explore the exhaust/output side of the equation. (which is the same basics just on the output side so surely you can extrapolate in either direction for yourself). Skepticism is an admirable trait as long as it doesnít keep one in a state of ignorance.
The biggest misconception is that the fuel side is the majority of this process. Wrong, wrong, wrong. It is a portion. But, the real magic lies in the air. Fuel and flame are nothing without air. Air can burn as it is a fuel in and of itself and reacts as a catalyst with the gasoline, alcohol, thus the true power.>>
Ok, done. Obviously you donít buy this or me, or the way itís presented. In whichever case or all of them. You obviously have internet; Research yourself. Or ask someone who you trust to have the learned and applied knowledge and experience in these areas. Save us both some time. I have such and have run this by others who have also. Donít just pull claims out my ass. That just sounds, and just plain is, stupid. Smell what I got cookin there? I promise you it will pass any knowledgeable litmus test.>>
Now, if you donít and still want to dispute, run your exhaust (any aftermarket) jet your carb (anyway you want) rip off your air box, put an open, bare, run-of-the-mill filter (cause they are all the same, right????) and go to your bank and get all the benjamins you can lay your hands on. Run anyone who has those plus a Hyper and a K&N. Get humility, broke, and an education the hard way and all at the same time. You will lose. True, proven, fact.

^^^ ShitHat You sound like a fucking sales man...A hypercharger is more hype than it's 3-400 dollar cost. Besides if we'd have wanted 200HP out of our bikes do you think we'd have bought 750's?

Sorry you feel that way. Not my Approach to sharing. My Reaction to condemnation without investigation. The espousing of the absurd, illogical, and uninformed as refutation and factual just chaps my ass. Now that last part was definately condescending. (and said jokingly as to represent your link in a sentance)
