What Balancer (Damper) are people using?
 

G'day again all,
Does everyone still just run the standard 8" GM Balancer / Damper on their Ext Balanced BBC?
I ask because I have just realised I have a Mk 4 Balancer on my Gen VI 454, only diff I can figure is timing mark vs timing tape in degrees. The one I have is a bit rusty and worn though and I am looking to replace it. I was wondering if I should go a TCI 8" Rattler or just replace it with a GM Gen VI 7.4, 8" Balancer?

What does everyone / anyone else think?
Any input would be greatly appreciated.
Cheers! :ernaehrung004:

the dampers on all ext big blocks are the same, flywheels different on the gen IV vs gen V/VI at the rpm we run I run a std gm balancer...now on my top sportsman race car we run a ATI superdamper....Rob

ATI Superdampner

ATI on both of my blower motors.

Depends on the power you are making. I don't like the stock GM balancers because of the rubber isolator ring. They get hard and split and the outer ring can spin. For a good stock replacement, I use Powerbond. They are under $200.

On anything over about 600 hp, I use the 7" ATI.

Thanks all!
I've had a look around and as it turns out, Powerbond is Australian anyway! (who new?)
So at around 500hp I'll be safe with an 8" Powerbond then?
Why go down to a 7" ATI over 600hp? Could I use a 7" ATI on mine? (would it hurt to use a smaller diameter?)
Cheers

On an externally balanced engine, I like to use the larger diameter to help with the balancing. On the larger hp engines, I use the smaller balancer because they are internally balanced.

There is no problem with you using the ATI. I think they are the best. It is just not neccessary at your hp level. They also make an 8"

Thanks Eddie, that answered all my questions!
I'll keep an eye out for an ATI 8".
Thanks!

i like the ati,but not necessary for your application,replace with stock gm unit,and use the xtra money for BEER.:ernaehrung004:

NICE! :drink:
Sounds like a plan.
I guess if it doesn't make more power or increase reliability it's not needed right now!
