Open V8

Open V8 is a working V8 engine you can take apart in your hands.

Press START and the engine fires up. Every part moves exactly as it does in a real engine: the crankshaft turns, the pistons and connecting rods follow it, the camshaft pushes the lifters and pushrods, the rocker arms open the valves and the spark plugs fire in the right order. Step on the gas and watch the revs climb as the shift lights come on.

SEE INSIDE
• Explode: pull the lever and the engine comes apart into its parts – heads, valve covers, intake, oil pan and crankshaft – while it keeps running.
• Cutaway: slice the block open to see the pistons move inside the cylinders.
• X-ray: make the outer parts transparent and watch the valvetrain at work.
• Slow motion: slow everything down to 1/10, 1/20 or 1/50 speed. At 1/20 the idle is about 37 rpm, so you can follow every single firing.

LEARN EVERY PART
Tap any part to learn what it does: the cross-plane crankshaft, the camshaft and roller lifters, valves and springs, timing chain, ignition coils, fuel injectors, headers and more.

HEAR IT
The sound is not a recording. It is generated live by an engine synthesizer from the firing order, the revs and the throttle, so you hear the uneven cross-plane rumble at idle, the intake roar under load and the crackle when you lift off.

PUT IT IN YOUR ROOM
On iPhone and iPad you can place the running engine on your table or floor in augmented reality, walk around it, turn it and resize it.

BUILT FROM REAL NUMBERS
The engine is modelled from the published dimensions of a classic 6.2 L pushrod V8: bore, stroke, rod length, deck height, valve sizes and cam timing.

NO ACCOUNTS, NO ADS, NO TRACKING
Open V8 collects no data at all.

Great for students, mechanics, car enthusiasts and anyone who has ever wondered what actually happens under the hood.
