Saw this on the dyno today ...

Absolutely amazing to me how fat it went when I put the Hyperthingy on and how much jet I had to take out of it to get it back in range. That thing was like putting on the choke.

WOW that is amazing:wonderlan Looks pretty restrictive considering it is a K+N filter. What size engine?

yeah but how big is the filter in one of those? i mean pulling 100Hp through one of those sounds like a stretch to me.

hmm... fat compared to no air cleaner? Hard for me to get a feel for that. I'm not sure how well anythig flows compared to no filter - stock, forcewinder, SE, etc.

The Hypercharger is just a over Hyped piece of eye candy. Never was a fan of that big hyped chrome clunker.:roflblack

I would like to see the screaming eagle stage 1 filter setup compared to the hypercharger

I think now that you started the controversy it is time to add some perspective. I would like to see a huricane flow, a forcewinder and a SE setup. I would like to see this before I dish out 170 for a forcewinder. I like the looks of that one too. WAtCh it X. That skull has teeth and he might take the jewels as penance for that comment.

Hey, I hope you're not trying to dis the hypercharger. Look at the monsterous gains in torque at 2000 RPM. :roflblack

Nope, the Hyper flappy would just make a good paper weight for the office.:banana Sorry R i didn't know you
had a eye for that thing.

Not an eye for, I have one on my baby. If they would test against some other options I might change but I am not doing it based on a test against no aircleaner. I have never seen a dyno run where the bike actually had higher h.p. with a AC. Hence, the request for a more thourough test. Maybe they will sell a few hurricane a/c after this. Hint, Hint, Hint.

force winder for 170???
where?

See all you have to do is change the Flappy thingy out and all your HP woes would disappear.:banadanc that thing is like putting your hand over the throat of the carb and suffocating your motor to death.

I'm sorry, guys, I do so much dyno work that sometimes I forget that other people don't necessarily have the same perspective.

I often do tune-ups with no air cleaner in place, but I always finish it off with a pull with the air cleaner back on. Generally what I see is a power loss and a slight fattening. I'd rather see a bike go out of the shop on the fat side of perfect than the lean side, so this is fine. I generally see a power drop, too, the size of which varies with the air cleaner. A really good one, I'll see almost nothing. A poor one, I'll see 3, 4, or even more hp.

The power drop on this one wasn't terrible (wasn't good either), what struck me was how fat it went. Here I was ready to roll the bike off, I do that last pull, and the bottom fell out, got something like 97hp and 11:1 on the a/f. I had to move the jetting a mile before I was happy with it again.

I just thought I'd pass it along, I've never in my life seen one move anywhere near that far.

Here's a comparison of the Forcewinder and a 3" Buell race kit filter for reference:

The Buell race kit filter significantly outflows the SE unit, though. The 3" HurricaneFlow uses the same filter element as the Buell race kit filter but improvements in other areas make it outflow the Buell unit. The 2" Hurricaneflow is pretty comparable to the Buell unit.

I don't have a printup of the dyno pulls, but dealer put a hypercharger on for me when they were installing my pipe, and they had some pulls with the HC and the SE unit. Believe it or not, the SE actually flowed better by a couple horses, and also made gains on mid range tourque.

So Basically what your telling me is the HyperCharger is a total POS (I can say this cause I have one!) and the SE would be an improvement performance wise over one. I bought mine strictly for looks but dont want to LOSE HP for a "look".
So...is the forcewinder a better breathing unit than a SE?

PS-best price to get one? (forcewinder)

:bump

I can get you a Forcewinder for $210.95 and that includes the bowl vent modification for free. If you don't do the mod you will have probelms and i doubt any other dealer would have a clue what to do. :)

:roflblack :roflblack :roflblack I had just the opposite result with mine the SE was more restrictive than the HC. There are differnt makes and models of HC and Kuryakian makes an adapter to give even more air flow

rottenralph,

Now you've seen a dyno run in which the AC actually increases HP with respect to no AC, at least at high rpm. Something to due with resonance caused by the length of the intake elbow...

I noticed this on the NRHS web-site last year, and that is why I bought the FW.

I think what some are not taking into consideration is how open are you? Meaning... If you open one end and close the other or not open it enough then you lose power and then you have to take into consideration how much air is getting in and these dynos are great for checking a bike standing still but what do you suppose would happen if you took it on the road where the hypercharger was intended for. wind velocity definately helps with all ac's but the hypercharger does have the flaps for a reason and they do actually work with the air to allow the right amount of air flow. As you can guess I do have one of these origionally for the looks which are subject to the owners preference, however since I've owned it I have had no problems getting power from it and cant even imagine what 2 or 3 hp would do over all. It already goes faster than I even want it to do and I like speed. So if you are gonna buy a pipe because of a Dyno chart or cams or heads I can see why this would be important , however for an air cleaner just make sure it's open to the air.

yeah but how big is the filter in one of those? i mean pulling 100Hp through one of those sounds like a stretch to me.
It is a stretch. Kuryakyn says it's good to about 100HP, and that's right where this motor is at. Try the Hypercharger Pro, which is for motors in this power range.

i am going to disagree here. theoretically, what you say is true, however, in real life, there is not a 'ram' effect with the hypercharger because of the profile of the bike. the front end causes more wind to bypass the ac. in order to have an effective ram effect, the ac would have to be sticking waaaaay out to the side.

Have you actually seen it? It sticks out almost as far as my fat leg. And I have to wear chaps to keep the cold air off of my leg.

Interesting that the forcewinder put out the most HP from 48 - 57 MPH, and again at 80 - 103 MPH.

Air acts very much like a liquid - from many years in the fire service, I know that as far as an effective firefighting stream, sometimes a smaller hose, and if you're talking "old school", a smaller diameter straight bore nozzle tip, which are not used much anymore, will perform better, and the shape of the hose lay (straight as opposed to multiple curves) also has an effect.

You can put a nozzle with an opening that's too large, and you get only a very inefective fire stream, and it all is tied to the capacity of the pump.

That's why some exhaust pipes will work better if they are a little smaller in diameter, same with intakes. Engine displacement, RPM, intake shape and size, (and lots of other stuff) have to work together with the exhaust system to get max output. As Gale Banks, the turbo guru says in his ads, and it's true, "It's all about airflow."

I was talking to the dynoguy one day and he said that best bang for your buck is no doubt the SE aircleaner mod. The rest is just flash. Hell I felt bad for a kid who put his buell on the dyno stock, didn't like the numbers and went down the street purchased a forcewinder brought it back dyno'd again, only to hear "well at least you didn't lose any power". That's alot of scratch for looks.

Wouldn't some air would have to be forced through at speed? I know I feel a breeze on my knees, despite the front end of the bike - they may or may not be as good as something else, but they have to get more flow at speed than at standstill. And don't discount looks as being important - most have never really tested the top speed limits of their bike anyway (and never will). Of course, I still have the stock ham can, muffler, jetting, etc., so what do I know!:p :p

The HC on my bike sticks out so far that it took me almost 2 months to get used to it rubbing against my leg. And there is a lot of wind blowing on my knees. So some of that is going into the HC. I also have the butterflies removed. Another little secret I learned from a guy who used to race Sporty's is not to put all that oil crap on the K&N filter. It don't need it.

One other thing. If there is no wind blowing around the Hypercharger, how the hell does the engine cool.
Bob

has any body done a dyno with a ram flo fron trak-tek, i have one and it seem to be better than a buell race kit i had on
