OUTSTANDING! I do believe I have some 3/8 tubing in the garage. I'll be trying this.

I've been extremely busy lately. This and the time difference has kept me from talking with AFE. Hopefully I can get around to it today. I would love to get a new filter out of them under warranty and see how it does. I was talking with a gentleman the other day with the same setup as mine, only a few more miles, and his silicone level from last oil analysis was 3 ppm with almost twice the run time between oil changes. His is obviously filtering just fine.

My BHAF is sitting on the work bench waiting on the new turbo to get here (will be my fourth ) so I can swap it all out at once. I will be ditching the AFE at that point, but it would be nice to solve all of my issues with it just for closure.

 

ahh, its nice when the theory is borne out by experimentation. excellent work! you know what they say: Physicists think that physical observations are an approximation of mathematical laws. Engineers think that math is an approximation of physical observations. Mathematicians seldom make the correlation.

I've been in contact with the upper management at AFE (VP marketing and CEO) for some time now to verify their filtration efficiency, and I'm also discussing the venturi effect and AK's dust. I'm also working on them to get more serious about your dust results, AK. they should send you a new system.

 

I hope you don't ditch the AFE system AK. I have been one of your followers and hate that you have had problems. I wish AFE does as doug mentioned and comes thru with a new element, your testing is of great interest to me. My next gadget will be the turbo that meets the AKRAM TEST OF APPROVAL...
Just my selfish way to want to match your performance without the trial & tribulations that you have indured...
Lets get that turbo update going

 

Geez that sucks!

 

No more free turbo explosions! I'm gonna $tart charge'n!

I really want to go to a paper filter. If for no other reason....I have this really cool BHAF sitting on my work bench staring at me every morning. I'm dying to see if it works and how it performs. However, if AFE wants to help, I would love to stick on another filter and run it for an oil change cycle just to see how it does.

 

who sells the donaldson b105006 filter you speak about?

 

quote:
--------------------------------------------------------------------------------
Does anyone know the CFM rating of the stock air filter?

327 CFM
--------------------------------------------------------------------------------

I believe it was Gypsyman that confirmed a page or two later in this thread that the stock filter actually flows something like 675 CFM at 14" H20 restriction. Still not that good though.

 

The Donaldson B105006 is the only BHAF I have seen successfully hooked up. It required moving the battery box back an inch or so on that side for clearance. There is a post on it on TDR with pictures if you can find it.

If you look at the CFM ratings of the B105006:
Airflow @ 6" H2O: 450
Airflow @ 8" H2O: 590
Airflow @ 10" H2O: 680
...........I think we can do a little better.

I'm working on a Donaldson RadialSeal design that flows twice that:
Airflow @ 6" H2O: 882
Airflow @ 8" H2O: 1176
Airflow @ 10" H2O: 1470

I believe Gypsyman is working on one as well.

I haven't run across many places on-line where you can buy them. The best option would be to use the "Where to buy" link on the Donaldson web site, or Fleetguard, or favorite brand's site, and purchase locally. The only on-line web store that sold the filter I'm trying wanted 75% more than suggested retail. Purchased locally for retail.

One of the overpriced sites that come to mind is: http://shop.airflowonline.com/Mercha...tegory_Code=AC These folks do sell the B105006. It is a DuraLite Disposable.

This site has a lot of info: http://www.reliableindustries.com/ph...search_for=476, but after seeing some inconsistencies, I confirmed with Donaldson that this site's information is way outdated and not very close to many of today's filter's actual flow ratings. Their info is old and hasn't changed as filter technology improved. So, if you pick out a filter to try, you would probably do good to call Donaldson's 1-800 number and they will confirm the flow ratings before you sink any money into it.

The Donaldson web site has a pretty good on-line catalog as well, but few pictures. I like pictures.

 

guys. The stock filter is a Fleetguard AF26106 and has the following performance:

Capacity: 504.4 grams per J726
Final efficiency: 99.56% per J726 "AC fine dust test"
Clean element differential pressure: 4.66 inches of water
Rated flow: 452 CFM
Terminal differential pressure: 16 inches of water.

452 CFM at 4.66 inches of water.

So whatever is printed on the filter element doesn't matter much. you can buy a fleetguard 26106 that behaves as above, made specifially for the factory air box. thats the performace we have to beat.

better set the sights higher than B105006. That RadialSeal is looking pretty good, though -- it presents only 1" of water greater restriction than the AFE at 600 CFM (good enough!). Now there's a BHAF. So how do you get that thing to fit?

Better make sure the Donaldson meets 99.56% on the AC fine dust test per SAE J726. Some of those off-road high dust filters, mounted within 13 feet of the ground only have to meet the course dust test. typically, they only have to meet the fine dust test if they are 13 feet or higher off the ground. But, as with the 26106, the application spec itself may call for fine dust performance -- just make sure of it.

 

Confirmed 99.995% efficiency per AC fine dust test SAE J726. Had me worried there for a second.

 

Every-time I look at those numbers in print I can't help but wonder why mess with what works.
That is excellent filtration with less restriction than a B105006.

With my VA on level 3 I can't pull the minder down but I do realize the pressure box I have dials back in the upper RPM's.
I bought it for the low to mid range performance.
My truck is all stock except for the VA.

I am doing exhaust next so it will be interesting to see if better flow on the other end will enable the minder to come down some.
If so I think I will drill the box before messing with a good thing.

Where we all end up with in HP makes all the difference cuz even with my VA I am only 300/660.

 

well, you had ME going! I just verified with Fleetguard that its 99.56%.

But compare this with K&N which not only uses the "course dust test", (easier test to meet), it specifies filtration efficiency at "between 97 and 99 %"!

Matt400: yea its always good to go back and see what you're trying to beat. one thing to keep in mind though, is two things:

1. The flow of the intake system (not just the filter element) it whats important. so the air box, and intake tube are part of that. AFE testing shows that the factory intake tube itself contributes significantly to flow capability. Their own PG7 filter I think gains about 200 CFM when you eliminate the stock tube and use an open 4" torque tube.

2. The really low flow numbers on the factory systems used for comparisons in the after market world are probably for the entire air box and intake tube. It wouldn't surprise me to see a 450 CFM filter element, put inside a box and set behind an intake tube that restricts flow to the 300 CFM region.

 

You guys are gonna love this.

So if we proved (as I think we have) that the airflow in this thing is dropping the the pressure to the filter minder by 3" of H20, and if that is the equivalent of a 1,000 foot altitude change, are we also changing the pressure reading of the IAT/AP sensor? If so, is it helping or hurting us in the power department? Perhaps "none of the above"?

100 Proof

 

This is for the RadialSeal I'm looking at.

 

ahh, excellent. so it should beat the AFE in filtration and be equivalent to it in flow. nice. so how do you get this thing in there?
