HOHN

Well, some of you may have seen my TDR postings on building a better BHAF, based on the Donaldson PowerCore technology.

I make no money on this deal at all, and I won't be selling anything. I just wanted something with the benefits of a BHAF (good dirt removal and a DRY [non-oiled] element), while having something that moved a LOT more air.

I have recently received one of the filters for testing. It's not a truck filter, per se, but I've been able to rig it to work. I think it's actually a Gas Turbine engine filter

Specs are 1000CFM @ 8" water, 99.99% efficiency, 10.5" inlet, 6" outlet. It flows more air than a HX35 could ever need. On my truck (at high altitude) it gave an amazing increase in spoolup over a paper BHAF.

See my TDR post for pictures.

You can post question here if you like.

So far, this filter is the BOMB

Oh, and I don't think it will work on a 3rd gen, as it's probably too big.

I've been following on the TDR. Nice work Hohn. Do you think if you relocated the filter to the where the battery sits it would help with the kink?

HOHN

I don't think it would help much, as the battery doesn't free up enough space.

The fitment solution is one of two, imo. Either 1) find a way to adapt the 6" to 4" in a shorter distance (only need about 1.5-2 inches more), or 2) ditch the stock intake duct (the ribbed hose) and fab something up from scratch.

I will probably try the latter, as I can't find any 6"-4" reducers that are shorter at any local place like Lowe's, Home Depot, or whatever.

I bet you could probably even just set the intake hose INSIDE the 6" filter outlet and spray in some "Great Stuff" expanding foam. That would make an airtight seal and allow the usage of the stock intake tube. Unfortunately, that would make it a PITB to change the filter if you ever needed to.

I don't like having to use an adapter (more potential leakage points, imo), but I think it's the best option. I'm going to stick with the adapter, and then try to fab something to replace the OEM intake hose.

No price yet from Donaldson?

It's gonna be interesting to make a work-around for that kink if you don't relocate it. thanks for the post!

try an industrial electrical supply house for a 6 4 pvc or abs conduit reducer

I'm going to ditch the stock intake tubing. I think the ribbed walls make it unnecesarily restrictive. A smooth-walled hose should flow better.

That is flat out awesome! I'd have to come up with a new mounting system for my truck though. In the stock location on a 1st gen truck the inlet would be right up agianst the inside of the fender - not good for airflow. Of course, I could just hack a hole in the fender and mount a scoop over it. Ram air!

Thanks for sharing that with us, Justin.

HOHN

I was wrong. The stock tube is smooth on the inside.

That's a dandy of a job on the research, Hohn! I'm sold on the filtration and buy it once practicality alone...nevermind I could add more fuel Us first genners could just keep the tubing going straight out of the turbo bending down and slightly right pointing the filter right between the headlight and signal light. 6'' inlet...does this mean I need 6'' stacks now?

HOHN, fernco company makes all types of rubber adapters, they are used primarily in the plumbing/pipefitting industries, i know they have a 90* with 4" on one end and 6" on the other, you can also get straights. i'm thinking if you found a 6" pipe which has a 90* bend, you may be able to couple it with an adapter to make it a cleaner set-up.

I too am curiouse about the project, keep up the good work.

I would pay $200.00 to $250.00 for a kit similar to the one for severe duty use on the PSD. I saw one at the dealer here in town and it looked pretty cool. I think I will try to contact Donaldson and express interest.

You've got my interest, but I think $150 is about my limit though.

I wonder if somebody called a Donaldson dealer and gave them the part number (P/N PCD100028), how that price would be. It should give us a good indication of what the price would be if/when the prototype goes through.

Why not cut your reducer back? I heard electric carving knives go through those like butter.

Joe Diesel

would be a nice set-up if it works out, good luck!

Beast2B

i double the cut reducer. looks like you could gain (or lose) 1"-2" with just some trimming of the reducer.
can the 2nd gen intake tube be used for 1st or 3rd gen trucks to make it fit better?
maybe a chunk of dryer hose and you could run it thru the cab to the rear sliding window for some fresh cold air!

BoostdCTD

That spot would actually be under vacuum during driving.
