Hooniverse Asks: What's the Weirdest Intake Manifold You've Ever Seen?

568671_x800
 
I think it was Jason Torchinsky over at Jalopnik who made the bold observation that the intake on the Infiniti VH41DE has an uncanny resemblance to the face hugger from the Alien movies. Once you make that realization you’ll never open your hood again. Sorry Infiniti owners, it’s time to let somebody else check those fluids.
Intake manifolds used to be simple things. Hell, for the longest time they were logs cast right into the heads! As computer-aided design and the goal of eking out every last bit of efficiency and power from our engines, intakes have taken on a life of their own. Some are multi-stage, while others look like French Horns on LSD. We want to see those weirdos today. What is the weirdest intake manifold you have ever had the pleasure to behold?

      It’s genius. The runners closest to the inlet are longer than those further away to balance the airflow. Of course, it does look a bit odd.

        I tried to find a diagram of how the head flows to the valves- that’s a trip too.

    I always thought the Subaru SVX had more facehugger than anything else.

      One of my all time favorites. So much so that we equipped my son’s first racecar with one (the one on the left)…

      Always thought it would be cool to hot rod one of these, with through-the-hood butterfly style air scoops on top of each of those carbs. Especially since they’re offset a little bit.

    I once watched a guy take a brand new Edelbrock manifold and machine off everything above the base in order to weld in runners and a plenum of his own design.
    I don’t have a picture of it, so here is a Chrysler long ram.

      I suppose it’s weird in that weird just means out of the ordinary. You know what else means out of the ordinary? Extraordinary. This intake is extraordinary, and that makes it weird.

        Darn. I do love the look of that intake, but the engineer in me has to agree with that. (Though I’d like to give the original designers the benefit of the doubt and assume that those parts were chosen for their long-wearing characteristics… Might also be the case that having that manifold split up like that somehow makes service significantly easier, though I don’t know enough about these to know.)

          It certainly increases the number of parts, and therefore assembly cost.

      Wha…? Why? Were the flow characteristics actually significantly improved by this? [Edit: having seen a dragster down below running a reversed-flow setup on a Nailhead, maybe so, but still…wow.]

      1. Tiller188 Avatar
        Tiller188

        Perhaps, but for a given amount of target boost/power gain, by running an individual (smaller) turbo per cylinder you’d hopefully only get laglaglag-boom, as opposed to laglaglaglaglaglaglaglaglagKABOOOM, no? Actually not sure where the balance point is between having a smaller/lower-inertia compressor, but being driven by less exhaust flow over the turbine…

        1. Vairship Avatar
          Vairship

          I’m more worried about one turbo/cylinder combo spooling up earlier than another. What are the chances all eight come online at exactly the same time? Because if they don’t, the turbo that spools up first feeds it’s cylinder more fuel/air, which causes it to spin up its turbo more, which… That seems like it can create a nice little drivetrain imbalance

    Fore and aft side-drafts nestled within the valley of a Ford Y-block struck me as particularly weird until I learned this was originally a marine application with a premium on maintaining a low profile.

      Can someone who knows more about intakes explain to me how this would work, and why it would work better than a 4-bbl mounted to a dual plane? Or, if high-end power is the only concern, a dual-4bbl setup?

      1. Tanshanomi Avatar

        It’s mostly economic. Four Yamaha R1 CV carbs will out-flow dual DCOEs and meter more precisely than a 4-bbl for a fraction of the price.

      Am I interpreting this correctly, that this is actually passing fuel-air mix through the blower? Hoo boy…that’s a whole ‘nother meaning to “detonation”. Watch them boost pressures.

        I always take a step back and behold the owner with awe and a sense of impending doom when I see that; I want to take their picture for posterity. There was a goof who used to show up at Italian Motorcycle Day at the Larz Andesson Museum with a home brew supercharged Ducati single (just take a step back and let that sink in) with the cart before the horse, as it were.

    I always thought this made no sense whatsoever, as the Q45 has a longitudinally-mounted V8 and RWD:

      It’s for those who want their RWD car to look FWD so they fit in with everyone else in the neighborhood. Being different is not tolerated in Suburbia and is banned by most HOAs.

          The only ones I can think of off the top of my head were Ford’s experimental ‘T-Drive’ Thunderbird and Tempo with transverse straight-six and straight-eight engines, respectively. Photos below, details here.
          And had I been the person at Ford in charge of these rather unusual packaging exercises, I would have given the engines the intake manifold aesthetics to match the driveline oddness. T-Drive was strange enough by itself, but the Tempo gets the straight-eight and the Thunderbird gets the straight-six? Madness, I tell you. Madness.

      Huh. This might be the winner here — many of the other entries on this thread are various flavors of unusual/awesome/why not, but this one really is just weird. …and also extremely facehugger-y (if we include the feeder tube from the filter box to the throttlebody), for extra bonus points.
