The contest forum is a bit slow so I decided to make a contest.
Goal: Make an engine that can travel 1000 meters.
Engine must fit inside one of the two red boxes.
The engine must be either a ball spawn engine, a water spawn engine, or a high bounciness engine.
The scene cannot be altered.
The car can be either one wheel drive or two wheel drive.
Any gearing/linkages must be inside the car.
You may change the collision of the car.
You may not abuse loop holes.
I will grade the scene by deleting the hinge on the circle above the black box before I start the scene, the engine will have 4.8 seconds to "rev" up, after that the car will be dropped. When the car is almost to the finish line I will slow down the simulation and get an accurate time of when it crossed. The car with the fastest time will win.
It's a pretty simple contest but it should be fun, have fun making your engines.

Why car is out-of scale?
The car is out of scale to make the contest easier, since bigger engines tend to be more robust.

here's my entry:
"The engine must be either a ball spawn engine, a water spawn engine, or a high bounciness engine."
i know, but i don't like water engines, and BS and HB engines are too slow
Then you just wasted your time because I'm not going to count that scene.

Heres my entry, running on my powerful torpedo HE engine delimited.
You can remove the exhaust if you like, its only there for decorative reasons, and has no effect on performance.
Hold left to get the engine turning the correct way, give it a few seconds to rev up, then tap C once to get the clutch to engage. it is a little slow to catch, but it gives the engine more time to spin up before it engages anyway.
The engine is more at home in a 1910 car in fairness than this one but meh!

Enjoy! If it seems to be stuck going slow, you've engaged the clutch too soon and the engine isn't making enough power at too lower revs to pull away, it'll go much faster if you give it a moment to rev up.

can't use a spring engine?
Imagine the point is to make a spring engine, so doubt a medusa is allowed or a spring engine thats powered at a crank, but imagine a piston with a spring would be fine.
anyone else going to enter?
bronie - 52.75 seconds
torpedo - your engine stopped at about 170 meters.
gasbomb - no
xplane - no
Its reached the end everytime ive used it?
click the grey circle on the crankshaft and check its angular velocity, engage the clutch at about 20, thats what i do and its reaches the end everytime.
If you engage at too lower rpm, it will stall, but thats the same with any engine. Only hold left to start it though, it revs up by itself.
Yeah thats about what i was getting when i tested it. it speeds up alright once its in its powerband but its low end power is rubbish so takes ages to accelerate lol.
I expect people will be able to beat that without too much trouble.

it should turn over just by spinning the wheel the right way or already be started
the higher the Hz the better it performs
so if you can, run it at the highest Hz you will
