Turbocharger, airsoft motor powered

thingiverse

Turbo using airsoft long type motor. You have to get the pinion gear off somehow though, it took an angle grinder for me. These motors can spin at over 25k RPM at 12v depending on how they are wound, and they are cheap. This turbo makes a pretty good blower but there's no real "boost" to it. I tried to inflate a balloon but had no luck. I didn't really design the snail shell housing for 3d printing so you'll have to find a good spot to split in half to print and then glue it together like shown. You'll need an arbor press or vice to put on the impeller, it's a tight fit. Give it 1mm clearance from the base of the motor. Use M3 ~8mm screws to put it all together and don't forget the spacers.
