Lightbulb cold-air filter/reverse scoop alternative for FC3S w/FMIC

cold-air filter/reverse scoop alternative for FC3S w/FMIC

From Justin of Precision Fuel Injection.

If u have a FMIC
Firstly, Adequately duct and seal engine bay for total regulation of airflow thru engine bay.

1.Instead of reverse scoop.
Cut as many/as large holes in the Firewall as is safely structurally possible, in whatever distribution is most beneficial for airflow, so the air goes

    2. With the turbo bonnet scoop:
    Make a mount (fibreglass mould for best fitment I s’pose) for a big square commodore type airfilter box, will seal nicely up to the stock scoop opening, with a mandrel flange going down from your little custom filtered airbox, into the turbo, so you are getting nice cold air going smoothly into the turbo,
    it is all sealed up, so there is no “random” air just going into the engine bay thru the unemployed stock scoop doing nothing, (creating turbulence, whatever.)
    ---

    It's an idea i guess.
    i'll wait til i see him start drilling holes into the firewall of his own FC before i start stabbing away at mine.

    keep swinging thru the trees!

    My mechanic says that air intakes are not needed, and the engine would work better if you just installed a blocking plate. Afterall, the space shuttle doesn't have an air intake, and it's faster than anything at the drag strip.

    a space shuttle runs off liquid O2 so it does not need oxygen to make fire but we do.

    **** mate, what do u want me to post up?
    I hear these ideas & theories from guys that work these cars for a living, so i have to give them some benefit of the doubt, regardless of how dubious i may personally be.

    How many 450odd rwKW rotaries that can be driven daily have YOU churned out? theory is established from experiment, i *respect* the on-the-edge mechanics that push the limits to find what works, and what doesn't. these guys, especially that anti-BOV theory guy, are full on Drag Race guys.

    I personally believe that there is no reason to deviate from turbocharging theory as dramatically as those two guys, but their expertize lends their ideas at least an iota of credibility, so i just thought y'd all be interested.

    and anyway, wtf is wrong with this guys idea to enhance airflow thru the engine bay, whilst utilizing the redundant turbo bonnet scoop as for a cold ram-air box setup? if u ask me, it is a good idea. The only negative technical feedback i received on it was that apparently over speeds of 90kmh, air doesn't flow into the bonnet scoop very well, but more over (or was it around, CR?) it....which would kinda make the TMIC suck even more....

    glad i've gone the FMIC,

    You're the same one who posted about anti-BOV and anti-Wastegate "rotary experts"
    I'm not saying they're hell of mechanics but I saw people prove you wrong on both accounts.
    The stock intake is a horrible horrible place, because it is in a bad place aerodynamically

    And myself would be against cutting too many holes in the firewall, and I would think that a vent would be better for an FMIC, and for airflow.

    Not that I don't love reading about the things you hear, as they inspire conversation about more technical jargon and they are sometimes bad, sometimes good, but always good to know more factual information about the engine and whatnot.
    Thanks,

    node, I got to admire your dedication and enthusiasm to the RX7.

    your car is going to be bad ***, even if it's stock, when you get it that is.

    Intake should be on the left side. not right. considering the exhaust is on the right side. cooler air = better for engine. hot=bad
    oh, you N/A people have to worry about ram air, turbo people don't.

    Cold air box solves the problem.

    and always hold hands when crossing streets./
