Flywheel balancing.

Post by andymyn » Fri Mar 08, 2019 11:19 am

Hi All, I'm just changing from imperial clutch/flywheel to metric. My engine is a re-built slightly modified 3.1 Essex . Question is do I get the flywheel lightened and/or balanced? The crank assembly has not been balanced although the piston/rod assemblies have been. I'm getting different stories from tuning people, one says don't bother, one says yes definitely and another says it'll make it worse!!!! Help!!!

I have also heard conflicting opinions on this. I have spoke to Car Clinic in Darwen who will be building my 3.4 engine and they said it's perfectly safe to remove a small amount of weight without going over the top. I have driven a 3.4 essex engined 6a belonging to a member on here and it revved much smoother than most others Essex engines I have driven and still gave a nice smooth idle. From what I gather, an excessively lightened flywheel can give a very lumpy idle as well as being dangerous. I guess like all things, in moderation. I will be getting mine lightened as per Car Clinic's recommendation

You could speak to TTV Racing: ... =flywheels
They have always been very helpful.

Rotational balancing for a V6 is "usually" recommended. Changing to a TTV flywheel when I rebuilt my engine made a positive improvement in terms of the way the engine feels and the way the revs build.
