It's a flat plane crankshaft, alright. Unfortunately, a flat-plane doesn't work with V6s. Make it a 90 degree 8, or an any-degree 12 and it'll work.*

*in the real world. In Legoland, it's perfect.

Flat plane crank in a 90 degree V6. It's awesome.

flat plane v6...don't think that's the wisest layout. Don't think it'd work at all with 6, but i'm not an engineer

Im curious, why won't a flat plane crank work in a V6?

How is that possible without a three lobe crank? A 6 cylinder engine has to fire every 120 degrees.

Flat-6, non-boxer, but still a 180-degree V-6. Double it, and it would be an accurate Ferrari Flat 12 crank.

A V6 is two inline threes, there's no way you can have a three cylinder engine with a flat plane. 1,4,8 cylinder, sure, but once you start getting uneven cylinders per bank, you have to break up the journals into three throws. (unless you go 180 boxer)

Yes, but that only works because of the 12.

Good point. It could be a 2-stroke, which would change EVERYTHING.*
