    Air Cleaner

    just wading my way thru the list of consumables needed to keep the beast on the road and made it to the air filter element....

    hmmm tracked it down to a donaldson G070017 housing with the P827653 element..

    einstein i aint, but by my calculations this engine sucks 230+ CFM at 3500 rpm and then some for the 10lb boost...

    correct ?

    hmmmm, bitching... the 70017 is only good for 200 CFM

    so, that begs the question what air filter setup do others run ?

    i hear the genuine item is a donaldson unit?

    anyone know the part number so i can have a look at what the specs on that are?

    Have you got a restriction gauge on it?

    I've made my own filter housing and use a landcruiser 100 series element inside. It's huge though.

    Donaldson ratings are very conservative. From memory they provide the rated flow at around 80% blockage.

    Good to see that red beast go to a good home.

    I just hung the expense, and went for the housing and filter specified for the 6x6. Makes the setup much easier to install, nice and secure ie H2O intrusion, you only ever buy the housing once!.

    Don't quote me on it, but I think the outer filter is P700071 or something close, I don't have the exact info, because I'm in your neck of the woods.......and mines in at BOR......

    The OE filter is a huge donaldson unit with a secondary element - this is the same spec as fitted to all off-highway diesels (earthmoving equipment etc.).

    Don't have PNs though, but the OE filter is much larger than yours, so would flow better.

    @ 3500 RPM

    333 CFM for the 4BD1-T

    202 CFM for the 4BD1

    @ 1800 RPM

    171 CFM for the 4BD1-T

    104 CFM for the 4BD1

    @ 600 RPM

    57 CFM for the 4BD1-T

    34 CFM for the 4BD1

    Standard filter is Donaldson FH003-0429 (numbers a bit illegible, so this may not be dead accurate). Element P90-0433, guard element P90-0434. Just got a set of elements today.

    My spreadsheet puts a 4BD1T with 15psi boost, no intercooler and 80% VE gives me 297 cuft/min.

    Intercooling (60% temp reduction) gives you another 50 cuft/min.

    Unless I am misremembering, the maximum rpm for the 4BD1 is 3200rpm and for the 4BD1T 3000rpm, although I am sure some have "adjusted' this.

    3600rpm for the truck 4BD1T. Industrial engines were probably governed lower.
    That said, I seldom go over 3000rpm.
