This is a mini scale V8 paper engine that works and functions like the real thing, hell it even sounds like the real thing too. Not so often do you see an engine made out of paper and in this size working so good. Measuring in at 1.25 inches long, just under an inch wide it truley is a test of endurance for the builder.
The V8 paper engine is fed air through a throtle valve connected to an inflated balloon. The paper model contains a working crankshaft, cam gears, cylinder heads and an intake manifold. The pistons even move in sequence when the output shaft is moved.
