LMM: engine balancing

[CRAWLEN]

This might be a stupid question, but cant find the info I need.
So coming from gasser engines, normally doing a an engine build with new crank rods piston ect it would all be balanced with the balancer,flywheel and clutch mainly only played with manuals.


So my question is since I'm putting a compstar crank, carillo rods and pistons. Do I need to get it balanced?



In the balancing, do they need the flex plate and tourque converter ? As this is the first engine I'm building that will use an auto. Asking this beacuse I already bought a billet flexplate to suit the engine when i wasnt planning on building. Would this be fine to us if I get it balanced with the crank or would I be better off getting a zero balance flex plate

The thin "flex plate" and converter do not need to be balanced. Now if you have billet parts on the back, send it with the rest of the rotating assembly.

You have external balancing where you use the flex plate and dampener to balance rotating assembly.
Internal balancing is where you balance it with the crank itself using slugs. Witch uses zero balance flex plate and dampener.

I would balance it. You will need the balancer and flex plate but no need for the converter. Decide if you want a different balancer now or not.

I only just bought a socal super damper, guessing I cant use that then ?

you can use it but its better if you had the assembly balanced with it.

Sorry I thought ne-max was saying there is special zero balance, harmonic balancer

They're is a special zero balance damper and flexplate that can be used if you have the rotating assembly Internally balanced.

Who makes internal balance dampers then ?

The SoCal one you bought will work as internally and externally balanced. Remove the counterweight and it’s neutral.

SunCoast and SoCal make zero balance flexplates (may more companies)

ATI, SoCal, Fluidampr make zero balance dampers.
