NV4500 to 6 speed

Seems the guys using the filter Piers recommends/sells, 24-50512, with 40/3B or equivalent sized twins are doing fine with it. Not sucking out oil or sucking in the filter. So technically, any one of the filters on the catalog page that has the same or higher square inches of surface area should also be adequate. This should allow you to pick something that will better fit your space. I'm thinking about the oval shaped 7X10" OD base X 7" OD top X 8" tall. That should fit my space better and has a little more surface area than the 24-50512, so may be able to go with the more restrictive PG7 media and be OK.

The afe 24-50518 is a ok filter. I can suck the filter minder down in valet at 50 psi in the hat and 26 to 28 psi in the cold pipe. I am waiting on a new style filter to show up that should work well.



Brad, what is the deal with the new filter... ... anything I need to look at.

Try this place . . I know they make filters that are 99. 9% efficient at 0. 5micron and have capacities up to 2500 CFM :eek:



... dunno what prices they run, but this place supplies the filters for the HUGE gas turbines on oil refineries/platforms in the Gulf, but they also have similar to BHAF in varying sizes that you may be able to adapt.



Might have to add 1 foot to the front of ya truck to fit some of these bad boys in !!! :-laf



Go Here

BTW ... stil no luck on the other matter :{



LOL... I think I will send them an e-mail just for kicks!!!



AFE and K&N have yet to return my e-mail!!
 
Called AFE, and got some info.



The spec on the AFE 2450518 is 881CFM @ 1. 5" H2O



at 3" H2O it would flow 1245CFM bummer... it's even too small!!!



the filter I am using 2450512 is WAYYYYYYYYYYYYYY to small... looking at about 590 CFM @ 1. 5" H2O

Was that supposedly the highest flowing filter AFE has?



on edit: never mind. I see your only looking at filters with a 5" outlet. So why don't you go with something like the 2491026 and just use an aluminum reducer to bring it down to 5"? It definitely has the surface area to flow enough to surpass your goals. Even available with PG7 media if you want.

Diesel Freak,

This is a e-mail I got from K&N awhile back regarding flow rates between a drop-in and a universal conical... .



Dear Customer,



33-2056 flows 660 CFM

and the filter that 57-1525 is a conical universal filter part number

RC-4780 flows 1063 CFM



Thank you,

How much of a draw is necessary to achieve that flow rate?

A guess would be the one I use but it is a pain to make fit... ... ... . no bolt on here.

Yes, Donaldson has some units called the TopSpin for the OTR applications.

NOthing that would even come close to fitting under the hood.

i talked to k&n today. i asked about the re-0880 and a 41-1400. the re-0880 flows 1403cfm and the 41-1400 flows 2100cfm. the 41-1400 is about 17in long and 7in in dia. the re-0880 is about 16in long and 6in at the base tapering out to 4in at the end. both flange ends are 4in. richard

ok, back to my other question... what is the draw required to get that flow rate?



I have seen a single HX40 collapse the RE-0880..... :rolleyes:
 
df i gave you the wrong cfm for the 41-1400. the 41-1400 flows 2375. 05 cfm @ 1. 5in h2o. when i talked to k&n they said they test all their filters at 1. 5in h2o. richard

well, that would prolly work if it had a flange ID of 5"
 
1. 5" WC is all but useless for a spec point... . No one else uses it except the K&N and AFE guys. Gee, I wonder why?

Especially since following the "industry standard" spec of 8" or 10" or 6" would make the filters seem a lot higher flowing (by the numbers).

Methinks the testing they use is HIGHLY suspect... ...

Please elaborate?



1. 5" is a much lower draw than the 8 or 10 or 6 you stated.
