The coin does tip over at about 0:15. Still, you couldnt do this with a straight four.

nice i like that way too test the balanc

perfect

A inline 6 cyl engine has perfect primary and secondary order mechanical balance..thats why they are more durable...tractor trailers still use inline 6 this particular v12 was devised using 2 inline 6 engines..sharing a common crank.. so the inherent smoothness remains...no need for balance shafts and gimmicky engine mounts all the engines sensor systems were double though making upkeep expensive

it's all stock as far as balancing goes.

SMOOOOOOOTH!

As silk!

Did this engine get any special mods like extra balancing or is it stock?
