anyone ever done it? i think it would be a worthwhile mod, and i guess its not too much, but i dunno a lot about it.

yes I .ve done it on my road race cars. I am gonna send my stuff out for my FD also.
Its amzing how everythings spools likethe **** and no vibration or noise.Its just a little something extra for the highe RPM. |
yah, thats what i'm thinking it helps with. i think i might do that for my next motor

how is that exactly done?? is it the same as a piston engine??

the person who does the balancing has special weight sets that allow for individual static balance then dynamic balancing.The whole rotating assembly , flywheel, clutch too are balanced in sinc.This is important on bridge and periph port motors. i dont know how many of the drag guys do it but its very common in road racing where your sitting above 7500 most of the time at twenty minute runs.but it does help in reducing flex and vibration which reduces over all parasitic power loss and centrifuge forces of weight increase.
Ray Everingham(spelling?) cuts the length of the tire studs because of that little bit of weight win it spins at high pm it increases exponentially. While you aren't reducing wieght your keeping what you got in the round.that way it not like a tire with an egg.It spools faster and can go higher with out stuff start walking on you. |
Mandeville Auto Tech (Spartanburg, SC, I think) does this for $275, IIRC.
I'd pay it if I had the cash. I trust Roger with all things rotary. https://www.nopistons.com/forums/pub...1047683894.gif Roger knows his sh_t. Steve C. |

I have found that it is not necessary to re-balance an engine up to 9500rpm, as long as the rotating parts were intended to be used together by Mazda. Engines put together and balanced by Mazda, are very close to a perfect balance and 0 vibration, up to a specific RPM. If your looking to rev up and around 10,500 and over, then yes I would recommend balancing. I have seen some of Roger mandeville's work and it was bullet proof balancing.

anyone know of a good shop in LA CA capable of the work?
