Here's A Visual Demonstration Of A V8's Firing Order Using A Bunch Of Lights And Relays
It’s important to note this demonstration applies only to more conventional ‘cross-plane’ V8s. In these engines, the firing order between the left and right banks of the engine aren’t ‘even’, meaning you get a left, right, left, left, right, left, right, right thing going on, which is what gives you the trademark V8 burble, and a less balanced engine.
Flat-plane V8s on the other hand are even with a left, right, left, right etc firing order, making for a more balanced engine that doesn’t need such hefty counterweights on the crankshaft.
In case you were wondering: according to the uploader, the fastest ‘engine speed’ achieved in this video was the equivalent of 1500rpm, which was apparently too fast for the relays to respond.

Why does this sound like a Scania engine, or my hearing is f*cked up
What is the most balanced engine? I think I6 is the only perfectly balanced engine?
I6 and obviously V12 is even more because it’s essentially two i6 together
New Skrillex Song?
I just watched this 4 times
My room has only one piston which seems that is not for racing purposes…
… It just blown up :(
Why they made the engine fire left, right, left, left, right, left, right, right for crosssectional V8?
You pretty much have to do it like that on a crossplane V8. Go look for an animation of crossplane V8.
Only thing it affects though is the exhaust pulses, which end up uneven. But thta can be fixed with 180 degree headers
that even sounds like v8 too!
Am i the only one or did it sound like a cammed V8?
I do too
I must rev it!
