Yes I am currently designing a sports car powered by a W engine, it is composed of a twin turbo, 8 cylinders, 700 hp, 2800 rpm !
There will be a 7-speed gearbox. It can therefore do 0/100 km/h in less than 3 seconds and can reach over 500 km/h ...
This is not really the mechanics, the problem ..
The reason why the frequency is so high is due to the poor "precision", (without reproach), from algodoo to 60Hz. If I keep this precision, then kinds of "uncontrollable vibrations" will be perceptible and the fast speeds will jerky. I would try on my next scene to lower all the constraints and to improve the refreshment.
