Is this for school?  Of course not, it's 2 cool 4 school.  How long did you think it took those headers to get red hot?  Probably not as long as you think.  The picture was taken in very low light, and those short, separate tubes can't dissipate much heat.  I remember from one of my farm machinery classes in college, if you retard the timing, you can get stock exhaust manifolds to get red hot.

  1. I can remember working on a small barge at night in the Columbia river when we were dredging it after Mt.St. Helen's blew up that had an old Ford Flathead on it running an anchor winch.
    You had to stand right next to the damn thing to run the handle for the clutch to engage the winch and they ran flat out under a load.
    The exhaust went out and straight up into a glass pack muffler.
    The exhaust manifold got so hot and it was so dark that it got translucent and you could actually see the flames going through them.
    Cast iron manifolds no less.
    Your arm kept getting longer and longer trying to hold onto the lever and get away from that heat at the same time!
    It's no wonder I am deaf in one ear and can't hear out of the other.

    1. Phil - "The exhaust manifold got so hot and it was so dark that it got translucent and you could actually see the flames going through them." - That is one of the coolest lines from a story about equipment i have ever heard. As soon as I read it, I got a picture in my mind, almost as if I'd seen it myself. It's so easy to visualize. Complete darkness, with the only light coming from an bright orange three port exhaust manifold. I'm imagining it being mounted upside down. (Can you do that on a Ford flathead?) Although I've never seen an exhaust manifold become translucent and being able to see the flames right through it, I can certainly imagine it being possible.

    2. Naw, wasn't upside down, they had an elbow on each manifold that turned it straight up, kinda like a big rig's stacks.
