In my efforts to kill this engine I’ve started to design a few bits to slap a small charger on, this was the easy bit, but also I got it right on the first print, which is rare for me.

There are reasons why they don’t make these out of plastic.

  It’s a test fit part, jlccnc will make the final piece out of 6061

    Although I’d love to see what nylon cf could stand up to.

    Oh thank fuck. Solid looking print though! This is fantastic use for 3d printing.

  No idea what they are trying to achieve outside of the “trying to kill this engine” part. I’m just hoping for the video of what goes wrong. (Hopefully not one of someone getting injured)

    I’ve a very small 2 lobe pump, it’ll pump extra air into the engine, make extra power and hopefully some nice noises.
    
    Cheap engines make for fun toys, I’m surpized I haven’t kill it so far anyway.

  I’d run it for the prototype just for funsies until a shop can make the real part. It might last longer than you think.

    If it was for something smooth like an alternator, i’d give it a try too, but this supercharger will take a fair bit of power to turn at 11000rpm and the pulses/vibration will kill PLA+, PA-CF I reckon would take the abuse easly, but the pulley faces would need smoothing or it would eat the belt.

Looks sick! And even sicker that it’s on a motorcycle!

  It’s a honda dax replica by skyteam, with a yx125 motor, barely cracks 50mph but it’s the one that get used all the time,
  
  Charger is a very rare 60’s VW smog pump, by my meaurements it’s a 94cc per revolution
