Brick Experiment ChannelSome of you wanted to see Lego motor lifting an actual weight instead of a meter. Here you have it. 88 kg of granite is lifted to a height of 20 cm. It took 21 minutes. :)
Compared to the 220 kg machine, some changes were needed to increase the lifting distance: -String collection around the axles was widened from 1 to 2 Lego units. -Bushes used for strengthening the axles were replaced with Technic Reel 3 x 2 (32012). -Gear ratio was increased from 75:1 to 135:1 to compensate the increase in diameter (and therefore loss of tension) when a lot of string is wound around the reels. This also means that the reels or axles may break if put to maximum load when the reels are empty.

Thanks to diamabolo, David C. Roy, aeh5040 and Yoshihito ISOGAWA for the inspiration.
Zylo is based on a wooden kinetic sculpture by David C. Roy. Hyperboloid Spinner is by diamabolo. Contra-Rotating Beams idea is from diamabolo, but I used unmodified Lego gears, whereas the original had a hole drilled into a 40-tooth gear. Tower Curves idea is from aeh5040, but I used different waves and gearing. Driving Ring idea is from Yoshihito ISOGAWA's "Cycling", but I used a big droid wheel. Hoberman Linkage is by diamabolo. Wave Machine is by diamabolo with a few modifications.

Base rules for all builds: -max length 1 meter -no steering (to simplify the builds) -only Lego parts used
The answer to the title question: Yes in general, but it depends on the wheel size and balance. The best speed improvement was from 5100 RPM to 7000 RPM which is a 40% increase. Some wheels didn't gain much as they started to vibrate in high speeds. The smallest Lego wheel didn't spin any faster in vacuum.Lego Vacuum PumpBrick Experiment Channel2021-10-23 | Quick build and test of a Lego pump that sucks air. It can generate a 70% vacuum.

Note: In real life the U12 and X24 have 3-throw crankshafts (pistons are 120 degrees apart) and the 42-cyl has a 6-throw crankshaft. Those are a bit complex to do with Lego so I used simpler 2-throw cranks (180 degrees). Thus firing orders are not correct in those engines. Also the 42-cyl Zvezda M503 was done with radial-6s instead of the real life radial-7s because I couldn't find proper Lego parts for connecting pistons to the crankshaft. The Sherman 6046 U12 engine gearing and phase offset between the shafts were unknown to me so I just guessed them to be 1:1 and 90 degrees. In other ways the models should be correct (hopefully). The V8 has a flat-plane crank that were used in Formula One engines. Lotus 46 H16 flat-plane crank, gearing and phase between the shafts should be correct according to the schema image I found (shown in the video). The U12 has both crankshafts rotating to the same direction as was explained in mapleleafup forum.

Presented in order from worst to best. Enjoy!
Test method: adjust the slope angle until the driving car doesn't slide down or climb up but stays in place measure the angle of inclination calculate the coefficient of friction = tan(angle)
Potential sources of error: traction varies along the wooden board (maybe +/- 1 degree of error in spots) wheel rotation speed varies (faster rotation adds maybe even 2 degrees to the result with some tires, tried to minimize it by using L-motor with large tires) vibration (happened noticeable only with 15038c03, those errors were omitted) weight varies (shouldn't matter in theory) uneven weight distribution on the 4 wheels angle measurement inaccuracies == the results are not very accurate, but I'm confident they are roughly correct
All wheels were wiped clean before testing.
The material of the wood board is pine, untreated https://www.biltema.fi/rakentaminen/sailytyshyllyt-ja-hyllytarvikkeet/yksittaiset-hyllyt-ja-hyllykot/hyllytasot-liimalevysta-2000018835

Nothing special in the hull, tracks and suspension. Many other Lego builders like Sariel, Kelkschiz and Matze Glatze have built better Lego tanks. But the gun is pretty powerful. I've never seen anyone make one that shoots soccer balls or uses a long wind up string to arm the rubber band. Theraband Gold was my choice for rubber band (very popular in real slingshots). The result is a bit dangerous. Not for kids! Use eye protection if you ever try to make it. The video is edited in retro 70s style with funky music. Enjoy!

No need to drill holes = no leaks. At the end I test it in a swimming pool. Enjoy!
Differences to the first sub youtube.com/watch?v=tGEZApd9MMk -rectangular hull (need flat walls for magnetic couplings) -snap-and-lock lid (more reliable, less leakage) -bigger motors, more motors, more propellers -depth control using propellers (IMO more accurate compared to a syringe ballast tank) -lead pellets for ballast (easier to adjust, both shape and weight, compared to steel plates) -captain (thanks everyone for pointing out this obvious missing part :))
