Harmonic Balancers

[Roady]

Hi all,

 

Just wondering for those using ATI balancers is there a preference or why choose the 7.074” (2.5kg) vs 6.325” (1.8kg).  Obviously a larger rotational force for the larger one.

 

Engine it would be going on:

L28 

L24 rods

Flat top pistons

 76 degree cam

Triple Webers 

 

cheers for any help and suggestions

Do you have to have an ATI balancer 'balanced' before fitting? Also the v-belt pully is sooo small, will I have to get a different v-belt??

Do you mean the OD of the pully is small or the V-groove is narrow?

OD of pully is tiny, compared to original

If you spend a lot of time in low RPM ranges, you might have a problem with the alternator charging.
Stew Wilkins sells an larger pully/hub adaptor to rectify this issue.

I think I will just sell it if anyone is after one at a good price.
