Would anyone know how much volume the Ness Big Sucker Stage 1 flows?

Thanks

just received an email from Arlen Ness tech support, and they sent me the flow numbers for their air cleaners.

Stage 1 Big Sucker - 200CFM
Stage 2 Big Sucker - 250CFM

On another forum, someone posted the numbers they received from K&N about their air cleaners.

E-3014 = 248 CFM RK-3009 kit
E-3037 = 301 CFM RK-3910 kit
HD-0800 = 231 CFM SE replacement

Thanks -

I just found this on another site also - don't know accurate it is, but they are the same as what you found:

HD stock - 171 CFM
Stage 1 Big Sucker = 200 CFM
Stage 2 Big Sucker = 250 CFM.
Kuryakyn Twin Velocity = 270 CFM
K&N RK3909 = 233.3 CFM
K&N E-3014 = 248 CFM RK=3009 kit
K&N E-3037 = 301 CFM RK=3910 kit
HD-0800 = 231 CFM SE replacement
Doherty Powerpacc = 287 CFM
SE Air Cleaner = 287 CFM
Zippers = 321 CFM 

If this is correct, a Ness Stage 1 appears to be the lowest flow of the available a/c 's

So if I understand this right the SEAC has better flow than the HD-800 K&N filter as part of the 'Roll Your Own'?

The idea that the SE filter flows more than both Ness filters or the K&N HD-0800 is ludicrous; ain't gonna happen unless you get one like I had that disintegrated.  Once the material falls apart the flow rate does jump up.  If you look at that list, I would suspect a typo.  What are the odds that the Powerpacc and the SE would have identical flow rates?

This looked a little strange to me also. Looks like a little more work needed to verify these flow numbers.  Like I said, this came off another board (HD Forum)

As the saying goes - don't shoot the messenger!

Wasn't shootin' at you Bill, sorry if it seemed that way.

This is where the motorcycle industry needs a Consumer Reports - Motorcycle Division.  You really can't go by manufacturer's claims, and I'm not aware of anyone doing impartial and independent comparison testing.  The motorcycle rags just print what the manufacturer (advertiser) tells them, so most of that information is useless.  To get meaningful data, you need to have all the filters tested using the same equipment and the same protocol.  Who wants to volunteer to buy a good flow bench and several samples of each filter for a definitive test?

I understood your response as it was - a logical statement about some numbers that looked suspect at best.  I just wanted to make it clear that I was not posting these as fact, just passing along some data posted on another board.  I've been reading this board since 2005 and I've seen what can happen here to people who talk out their a_s! 

I agree about the testing, flow data on different heads and head modifications seems more available than for simple off-the-shelf air cleaners.  Sounds like a job for one of the magazines - but they wouldn't give an unbiased result because of their relationships with their advertisers (air cleaner mfg's).

Stage 2 Big Sucker - 250CFM

E-3037 = 301 CFM RK-3910 kit
HD-0800 = 231 CFM SE replacement


This is what I got from Ness Tech Support - may be right, may be wrong.  Now I'm just confused...

"Hi Bill,

 We had an independent lab do the flow testing, the 251.44cfm is for the Stage Iā€ 

 Here are the numbers for air flow on the two air filters.  These numbers are based on 28ā€ water using the factory carburetor.  Please let me know if you have any questions.

 

880-112-1 air flow 251.44cfm

880-113-1 air flow 255.26cfm

 

Both numbers are SAE corrected and you may notice there is only a small difference between the two.  This is due to the carburetor being the limiting factor in total air flow.  However, the 880-113-1 filter does provide additional dirt holding capacity.  This allows the larger air filter to flow more air than the smaller one as it loads up with dirt.

 

Hope this helps,

Danny
