An I6 isnt the most balanced....its just plain balanced. There are other configurations that are balanced too.

The balancing really isn't the limiting factor for how hight it can rev. Once you hit a certain piston acceleration it gets expensive to get things to hold together. Also, preventing valve float is a big issue.

If you're referring to the "most balanced," yeah he's crazy.

It's "more" balanced than an i4, but I'm not even sure balanced is the word. Smoother would be better.

Piston speed is still the big problem.

Exactly.

An I6 is smoother because it has no dead time between power pulses. It is not what I would consider the best balanced engine.

90 degree V8 engines are probably one of the better balanced piston engines.

Rotaries are the best balanced engine.

;D

I am not much for futuristic appearance that things are going towards. I like to keep it stupid simple.

No no no gentlemen. An I6 IS balanced.....100%. There are a few engines that have perfectly balanced primary and secondary forces. Off the top of my head i know the I6, flat 6, V12 and Flat 12 are balanced. There are a few more im sure. A 4 cylinders secondary forces make it unbalanced and it needs two balance shafts to make it a balanced system. A V8 is more balanced than a 4 cylinder but not as good as an inline 6.

Regardless, the biggest issue is piston speeds, not the balance. Shorter stroke = higher revs.

Inline 4 on a bike, smaller displacement and stroke = higher revs and lower torque
Inline 4 on a car, larger displacement and stroke = lower revs and higher torque

The balance doesn't have much of an effect on revs. A balanced engine will have better reliability but the revs won't improve much, if any.

Yep. Thats pretty much what i said in my first post.

Also, they said its a narrow bore so i assume the stroke is pretty long.
