How Fast Can A Piston Engine Go In Scrap Mechanic? 

As a car enthusiast i appreciate the work ❤

My next upload should be soon, around Sunday/Saturday

Check out my "compact spud gun car" on the workshop, 2 speed gearbox and quite fast for a potato engine. A lot of the mechanics could be useful for you, especially with thruster engines

Me and some people I know can help and teach you how to make much faster piston cars. They can help you pass 100kmh and 200kmh

I could show you true speed if you want to, even going to 500km/h. All vanilla still, more is possible then one may assume.

U get a better mic?
