1200 CFM Filter!!

[Diesel Freak]

Does one exist?



Or do I need to run two AFE filters?

I hope you are only wanting one for competition, but FWIW, the K&N RC-4780 flows 1,063 CFM. It's the same filter that they send with their FIPK for 2nd Gen diesels.

why would competition only be an issue.



if it was rated at >1200cfm, it would work great for every day driving.

The reason is in order to flow that much air something else has to give, i. e. the ability to filter out smaller particles of dirt.



When you dust your cylinder walls due to not filtering enough dirt out just to have a 1200CFM breather ability you won't have anyone to blame but your self.



What are you running that you requires 1200CFM of air flow anyway?

Cliff, you aren't going to package a 1200CFM filter (with any reasonable DP) that filters worth a crap under your hood.

You could always install a Farr Ecolite (1550cfm @ 8" water) outside the hood.

CFM flow specs on filters are useless with the differential pressure that corresponds.

ALWAYS ALWAYS-- how many inches of water for the CFM?

Heck, a regular AFE will flow 1200CFM, but might be pretty darn restrictive doing so.

I'm glad that was obvious to someone other than me.

lol



I knew what you were geting at, but I might be able to find a way to fit such a huge filter somewhere... . just need a torch and a hammer!!!



I do not intend to go with a lower efficiency filter, just a larger one.



I would love 1200CFM @ 5"H2O!!!!

enough air to keep 500 HP under 1250F

enough air to keep 500 HP under 1250F

if you have the right power combo you can do that with a regular drop in filter. :-laf

Why would you waste power on a drop in? A properly sized filter is the only way to go.

 

[mhuggler]

Anyone know for certain what a Donaldson BHAF flows @ 5" or 8" H2O?

sorry dude, not sniffing Nitrous here!!!

Cliff, I don't know what it flows but I run a AFE with a 6" inlet, 24" long and it is one big filter and quite a pain to install as I had to change everything around it, but it was worth it.



I'm wondering what a 5 X 18 will flow, I ran that one on my first setup.

all i was saying is that it is possible to attain 500hp with a stock type of filter---i know because i have done it, not saying that it is the only way or the way it should be done----cfm does not equal hp---dont get confused on the marketing hype--high flow does not allways mean its better, thats my oppinion

 

[Diesel Freak]

umm you are missing the point



I NEED a filter that flows a MIMUMIM of 1200 CFM... not because of power, but because the twinset I built has the capability tomove that much air if I want it to.



A stock filter would not work with these turbos, I would suck the seals right out of the primary.



The current AFE I have is too small.



Jim, I have a smaller version of that... 12 inches long, with a 5" outlet.



AFE # 2450512

 

[Diesel Freak]

----cfm does not equal hp--:

you are exactly right



CFM = HP and if there is enough "excess air" left over... it also = low EGT



Speaking strictly charge air here!!



CFM into the turbo is not the same as the CFM out of the turbo... however mass flow rate remains constant.



But to achieve the required density ratio at the inlet plenum... . oh nevermind... you are using stock filters...

So what does a BHAF flow and does it matter if it's a Donaldson, Fleetguard, Napa, Big A... ... ... . etc?

There's your answer Cliff, two BHAFs. Oughta fit in a set of these. Complete the look with a set of stacks :-laf

this one works pretty well. i don't know what it flows, and i don't know where to find out.
