too weak to work yet

Nice

All my Radials have pushrods, rocker arms and realistic valves

Idea is good but it can't work on more that 500 RPM. It cant reach it. Well it could on about 300 HZ.

Whoa that looks good! You could work on some texture or boxes on the fan's belt with the fan script to make it look better

Thanks guys, but I will make it work, you'll see
I havnt optimized the thing at all basically. Just look at my rally car. it uses basically the same kind of engine with the same amount of cylinders and that thing is plenty strong.

Gent: I meant an engine that uses springs that change lenth/constant. or "variable spring engine" as I've heard them called. usually they just use a laser on the crank shaft.

The Linkage: I was actually going to do the fan belt thing

By the way, this engine is going to be for a very weak and slow vehicle anyways.

perfect. 10!
