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.

Is that a tesla V8?
are you sure about the fireing sequence for a flat plane v8, I checked on google and it had the sequence of a cross plane v8. I am not an engine expert so if I am wrong pls tell.
Wouldnt this be way easier to build by just wiring lights to an old distributor and spinning it?
