10/10

well the RPM's are fake too, But it's a nice car nonetheless. I just managed to get 6500 RPM so maybe slower engined cars can be made more realistic. Would be pretty nice if you could get it working at least at 5000 RPM @ 240 Hz before going dark

No brakes?

Very nice model and dashboard, but engines like that should have more "resistance" when they're idling. Had you ride on motorcycle? You dont need to use brakes above 20-30 kmh when throttle is closed. Just shift gears and keep 4000-8000 rpm so you will slow down fast. I mean you need to add constant brake on crankshaft and increase engine's torque.
I'm happy that negative adhession became useful, but engines with this tech could be really compact - possible to have real piston size and "nitromethane" efficiency. 0.56 x 0.375 m engine can have a several thousands hp. I have one i4 with 5000 rpm @ 8000 N*m {200 hz}. Impressive and crazy at the same time

Answering questions:
>"how you did that engine so stable?"
Circles should have less diameter than cylinder and timeToLive about 1-2 sim ticks. If they contact with cyl side, they move in random direction, not toward to piston.
