    Figured I'd share some pics and video of the home built turbojet engine I finished up recently.
    I used a cheap eBay turbo for the compressor and turbine stages. Pretty much everything aside from that was fabricated from scratch. Even the inlet and exhaust tubing was rolled from sheet stock. Mostly just a big exercise in metal fabrication & welding. And other stuff like homemade ignition and Arduino programming. Lots of time overall!
    Runs pretty smooth and rips at about 127 to 128 dB at idle.

    This isn't really going into anything, I just wanted to build it and hear it run. I may add an afterburner exhaust but this thing already kinda scares me enough. But for sure I'd like to build a bigger version sometime.

    Video link of latest run and walkaround:


    A few pics of the finished jet below, I'll spare you the 1000 pics I probably took during the whole process lol:

    If you put it in a rolling chassis, would it be Clubman legal?

    Some classmates and I built something similar in college for a class project. Yours is way nicer to say the least! Our turbo was from a 4 cylinder Mercury Cougar. The combustor was made using an expansion chamber from an old two-stroke go cart. We didn't have an exhaust nozzle. Ignition was from a VW bug distributor; we spun it with a drill. Oil was gravity feed. Some how we managed to make it run and not to blow ourselves up.

    If you were to attach a grill to that, would you cook a hamburger or a cheeseburger on it?
