    turbo size chart (borrowed from nasioc)

    during the FS downtime I started looking at the other forums on the net and came across this little piece of info curtousy of nasioc. Thought it might have some interesting info for those who'd like to have a general idea of what turbo can flow how much at 14.7 psi (granted, some of these are very capable of much higher psi, but this should be a decent reference point)

    Stock Turbo 360 CFM at 14.7 PSI
    T3 60 trim 400 CFM at 14.7 PSI
    IHI VF 24 423 CFM at 14.7 PSI
    STOCK HYBRID 430 CFM at 14.7 PSI
    IHI VF-22 435 CFM at 14.7 PSI
    SR 30 435 CFM at 14.7 PSI
    T04E 40 trim 460 CFM at 14.7 PSI
    Small 16G 505 CFM at 14.7 PSI
    PE 1820 510 CFM at 14.7 PSI
    Large 16G 550 CFM at 14.7 PSI
    SR 40 595 CFM at 14.7 PSI
    18G 600 CFM at 14.7 PSI
    20G 650 CFM at 14.7 PSI
    SR 50 710 CFM at 14.7 PSI
    GT-30 725 CFM at 14.7 PSI
    60-1 725 CFM at 14.7 PSI
    GT-35R 820 CFM at 14.7 PSI
    T72 920 CFM at 14.7 PSI <-- Note you would have to spin a 2.0 L
    engine at about 14,000 rpm to flow this much air.

    IHI VF 24 388 CFM at 18 PSI
    T3 60 trim 410 CFM at 20 PSI
    IHI VF-22 460 CFM at 18.0 PSI
    AVO 320HP 465 CFM at 17.5 PSI
    T04E 40 trim 465 CFM at 22 PSI
    Large 16G 470 CFM at 22 PSI
    SR 30 490 CFM at 22 PSI
    Small 16G 490 CFM at 22 PSI
    AVO 400HP 580 CFM at 17.5 PSI
    PE 1820 580 CFM at 22 PSI
    AVO 450HP 650 CFM at 20.0 PSI
    AVO 500HP 725 CFM at 23.0 PSI
    SR 50 770 CFM at 22 PSI
    GT-30 790 CFM at 22 PSI
    60-1 800 CFM at 22 PSI
    GT-35R 880 CFM at 22 PSI
    T72 1000 CFM at 22 PSI <-- note you would have to run a 2.0 L engine
    at >40 PSI boost to flow this much


    Sorry to have an on topic post for a change, i'll try and not let that happen again for a while

    ok so what im understanding is that these turbos work ideally at these certain cubic feet per minute? Cubic feet per minute thats what a CFM is right?
    RSX TYPE S...HAS FINALLY COME.

    BOOST....to be continued

    Where did they come up w/ these figures? They seem pretty a little off if you ask me. There are so many variances in each turbo. You pick up about 40cfm alone going from a E cover to a S cover.

    according to the poster on Nasioc, they were compiled using information gathered from the manufacturers tech sheets.

    I'd be willing to disprove those T72 numbers as well. If I decide to change anything this winter, I think a PT71GTQ might be in order. Seems to be the sweet spot turbo for all of the street car Hondas.

    I know of one Honda running Dave's turbo too, and from what I read he seems to be happy.

    How much of a difference though does it make using NOS to spool up the big turbas? Just curious.
    One time...

    It helps a lot, depending on the size of the shot of course. Without nitrous it takes me about 5 seconds to spool at the line. With nitrous it takes less than a half of a second.
