Title: Rotating Assembly Balance Question
Post by: Scoobum on November 16 2014, 12:50:31 AM
I always have the rotating assemblies balanced in my engines...cuz they rev out as smooth a silk. Is there a distinct HP/performance advantage to this...and if so...why?

Eeyup.
It works for the same reason balanced airflow to each cylinder does.
It's the old synergy and a rock under the rim of the Frisbee analogy.

Are there not many pieces to this balance thing? Aren't 3.8's balanced differently - not 50/50? If only we knew a machinist ( cough Radius) who knew these things?

Thanks Steve,but I can't take credit for my knowledge.

You're confusing the balance specification with the need to balance or not,if I read this right?

No, I inquire of this et al :

"The balancing took care of the vertical component of the vibrations and the motor mounts took care of the horizontal component."
