This 4 cylinder was the basis for the Mustang V8 engine. It was the first of my engines to exceed the 1000 rpm barrier. While it was a milestone, it is already obsolete, because i have switched to studless. The studless 4 cylinder runs way better and has 1420 rpms. This engine also has a tendancy to vibrate itself apart. But you will have fun running it anyway

LDraw
Is there is LDraw file somewhere for this engine?
Nope
There isn't one.
Air
hy, i want to built such a thing, and i ordered all the pieces which are needed, but with which kind of compressed air do you get it run?
Compressor
I run it with an ordinary stationary air compressor with a 50l air tank. But it was reported that a normal coke bottle filled with air makes the engine run well too.
