For you future projects i would recommend using WD40 for a lubricant, as water (in most cases) will slow you down due to it wanting to stick to itself and as well as the rotating parts. However, i understand if you don't like the idea of oily residue on your legos.

There's another way you can estimate speed - sound. Record the audio with it spinning at a known speed. Put the audio in a audio program (like Audacity) and have it do a spectrogram. You should see a strong peak at the known speed. That corresponds to the speed (albeit in revolutions per second instead of minute) or a multiple of it. Then take the gears off and repeat. You should see that peak move, so now you can recalculate and get the speed.

@Google_Corporation

Worm gears are famously inefficient. Like 50% efficient. If he needs to record speed but needs a reduced output, use spur gears, as they're typically 99-99.9% efficient. I've had extremely low power systems with 300:1 spur gear reductions run totally fine, but one worm gear, regardless of the ratio, will kill the same motor.

Offsetting the rod by half a plate upwards or downwards could increase the efficiency, as it can't spin with an extra full plate underneath, but likely could with half of one. Just leave a 5 plate tall 2 stud wide hole in the side and fill it with the inverted axle hole with a plate on top and tile on bottom. Use a bracket to hold the axle holder outside.

Have you tried using a "trumpet" also called a "velocity stack" on the air-intake side of the engine? How about using a duct that more smoothly transitions from the rectangle-shaped exhaust "port" of the engine into the round nozzle of the vacuum-cleaner? You could also try cooling the intake-air to make it more dense, therefore more air hits the paddles and increases the power of the engine.
