Algodoo

Maybe Xray can help you

Xray?? Lol no he's on the Thyme side of things...

There are some things you should take into consideration:

-The whole kart thing plus the guy weights 1400 kg, and everything but the engine is out of scale. By a lot.
For example the guy seems to be 6 meters tall...

-The gear ratios are completely messed up. For example, the last gear's ratio should be almost 1:1.

-When you did those engines, I thought they were just for looks. That piston travel is useless on Algodoo, you'll only achieve tractor engines with rather low torque and low angular velocity. If you want power you need torque and RPMs, so make the piston travel half of what it is now.

-I don't know how the killers are placed, but you kill the balls too early. You should kill them when they are close to BDC, like 15º or 30º of the crank before. If you can't do that easily use a killer ball that rotates with the ignition or the crank

Oh I see you use timeToLive on the balls. N o p e. If you use timeToLive you get close to 0 power on low RPMs... Use killers! The easiest way is making the spawner (white ball at the spark plug thingy) collision layer B, the piston collision layer A and B, and the spawned balls collideSet:= 5 (A and C). They need not to have collision layer B or you'll get a fountain. Now that you have collision layer C used only on the spawned balls, add a killer with collision layer C at like half of the piston travel and move it slightly until you see that the ball gets killed close to BDC. But don't kill it too close or the ball won't get killed when on high RPM.

@The Linkage That's alot to take in. I appreciate the feedback and i'll give it a go in my free time
