Big Honking Air Filter Installed (long)

[cumminsgetme]

ISBPilot,

The K&N 880 will give more turbo wine than the bhaf.

 

[Forrest]

I had the stock airbox, with a K&N filter & no snorkle. You could hear the turbo whine. The BHAF reduces the whine sound.

I have no experience with any K&N on my truck, but when I installed the BHAF; it was the first time I heard the turbo whine. Gotta love that sound.

Oil analysis in about a month

Well, I've had the BHAF on for about 2 months now, 3,000 miles and still haven't discovered any problem areas.



Will be heading out to Colorado in about 22 days, 17 hours (but hey, who's counting). l'll change oil when I get back and send a sample in. This should be a good test for the filter since I've driven something like 1,000 miles of gravel roads on this oil change. Very dusty. We'll see.

Added in edit; after pulling the gooseneck horse trailer in the Ozarks I've decided to install the 16cm trubo housing I've had in the shop for the last couple of months (thanks Piers). The reason I've held off is I'm not looking forward to the turbo lag I expect to see. But hopefully, it'll mean not having to let off on the big hills. Or not as soon anyway.

Moparguy, I will be curious to see what your lube analysis numbers show, otherwise all I hear is good from this big filter, keep us all posted.

Would the moparguy setup be of any help to us guys that aren't fully BOMBed yet? I'm stock except fot the 4" cat back exhaust and currently run a max EGT of 1200 F pre turbo and 18 lbs maximum boost. I'm now running the K&N replacement filter, but I would think that moparguy's setup would be better

when I install the TST #6 plate.

Any Input is appreciated,

 

[Deezul1]

Might be best to install your plate and see if you have an EGT problem. And if so then go to the BHAF, I sure like mine and it helped in several areas.

 

[boathead]

thanks deezul,

got another question, how did you get that avatar under your username, I've tried several times just using a .jpg, but it won't come up, what's the .php format?

thanks ,

Paul

I just went to the bottom of my user profile page and pasted it in from one of my picture files but had to re size it first, its fussy about file size.

Go with Fleetguard Filter

OK, with this BHAF discussion and filtering efficiency quiestons, I started doing a little checking on my own:



Napa filter = Wix filter (maybe some of you already knew the Napa filter is made by Wix).

Napa/Wix filter flow rating is 680 cfm . Filtering efficiency is 99. 9% like the Fleetguard.



Compared to the Fleetguard the CFM seems pretty low, which is puzzling. But this is per what the lady was pulling off of her computer screen. Could be she's wrong!

The Wix Tech line is 800-949-6698 if you want to call.



One thing to consider, anytime you buy Fleetguard products it benefits Cummins, since a considerable amount of Cummins' revenue comes from Fleetguard sales.

I would expect flow (CFM) to be measured at a particular pressure drop (inches of water, probably). It may be that NAPA/Wix and Fleetguard measure flow at different pressure drops - that could explain the difference. Without knowing the pressure drops each manufacturer is using, it's impossible to say for sure.

[CUMINNTSTRKN]

my local fleetguard-cummins dealer cautions against using any napa/wix filter, this is the reason. he says that wix makes the filter for napa to napa's specs not wix's. now i'm not saying that napa's filters are bad. just thought i'd share what i was told.



my bhaf should be here tomorrow!!

BHAF

Mopar Guy,

Thank you for doing the home work with the filter catalog for the rest of us. I installed my BHAF in my '93 and I love it. I am trying to convert other 1st gens. see "Kicking the sleeping dog" post.

Thanks for a great mod!

Just considering CFM flow rate

I have the RE-0880 and pre, 25-0880 on for 18K and a Jannetty heat shield.



K&N tech says the RE flows ~1375 cfm, and take off 10% for the pre, altho they say it's probably more like ~ 2-4%. ( I have the actual cfm they gave me, but not with me now... . it was definetly 1350 or more)



Fleetguard tech says the BHAF flows 918cfm. Obviously, for those who have been running the stock air box, the 918cfm has got to be a big improvement.



I have no concerns over egt's, turbo whine, don't tow, and drive hwy only... no dust concerns. My pre shows a little darkness after 18K and when I peel it back and look at the RE, it looks brand new. No oil samples, but I don't think I'm sucking dirt into my engine. Spotless turbo blades.



So, for my needs and desire for higher air intake for maybe more power, I think the RE is a better choice. Please understand, I'm not knocking the BHAF, I just think there are some TDR members like me who are looking for other points of view, and I'm not interested in stirring up the frankly tiresome debates on whether the K&N filters are good or bad. If the BHAF claimed more cfm than K&N or any other filter, I'd buy it.



If I'm missing something, please comment.

 

[Vaughn MacKenzie]

Rusty_JC makes a good point, all these CFM ratings could center around how much resistance is allowed to achieve the spec CFM rating the companies state. Obviously, if a great pressure drop is allowed, then the CFM is going to be higher given equal media and surface area.



The 1300+ CFM of the K&N is very interesting. I am a little skeptical of that value. About a year ago when one of our TDR members came up with the BHAF filter (or almost the same thing) he found out the resistance of the filter was only 2" water which was much lower than the K&N. As I recall he hooked up a gauge and actually tested it. The thread is about 5,000,000 posts back or else I'd try to dig it up. It seems the K&N was around 10-15" water and the stocker at 20" maybe (do not quote me on this!).



While posting, I want to add that I got an email from Wix today and the tech reaffirmed the 680cfm rating of their BHAF that the lady gave me over the phone yesterday.

Can I get a picture please of the setup up close THANKS

 

[moparguy]

Vaughn, in my opinion, you are exactly right, unless you know the test guidelines each manufacture uses, there is no way to compare the flow rates or efficiencies of our favorite filters. One of the lessions from my previous life in the natural gas biz, pressure drop is everything when it comes to flow rate. Dosen't matter if it's a gas pipeline, oriface in a regulator, our exhaust systems, or air filters. The greater the drop, the more volume you flow.



And that leads to a second fact, more pressure drop means higher speed of the subject gas, which leads to a higher probability that dirt will pass through a filter. IMO.



I still feel the only way to really know what's best, is to have a independent lab test the half dozen or so filters we use and let the numbers tell the story. Howevery I also know from past experience that it's very difficult to get a large enough group of people to donate the funds required to pay a lab.



If a TDR member has any contacts or ability to facilitate testing, that'd be great. My check book is ready to make a contribution.



JD, you out there?

other types

Does anyone know if the ECO-SE air cleaners with work in the same space? P/N AH1192 or if you modify the outlet, AH1193 or AH1197 they seem to be like the K&N setups some have tried. Would this be better or worse than the Moparguy filter. It says that the AH1197 flows at 960cfm at 8" W. G. whatever that means? Any help at understanding this would be good.

 

[RustyJC]

Jacob082,



8" W. G. = 8 inches of water column, gauge, or differential from atmospheric pressure (as opposed to 8 inches of water column, absolute).



As far as testing the various filters, I would think anyone with a flow bench of sufficient capacity could do it fairly readily.

I installed my Fleetguard BHAF last week before I made a trip from Seattle to Kettle Falls. Going over I was empty coming back I had my tractor. Truck was at about 17,000 GCVW with this load. I noticed comming home that my truck was making a much deeper exhaust noise or growel. I've made this trip many times never heard this deep of tone before. Is this just noise comming back through the filter. Anyone else notice this after installing their BHAF. Les
