Hi,
just wonder which brand harmonic damper match which unbalance used 4G64 100m stroke crank, 86mm Wiseco pistons, BC I beam rods, ACL race series bearing is preferred for a 2.3L built for occasional track and uphill run?

Thanks

 

Fluidampr.

 

Fluidampr, just bought that one for my build.

 

Also make sure you get the rotating assembly balance...

 

Thank you very much Guys

 

Exactly what I did on my 2.3, balanced the internals and added a Fluidampr.

 

Thanks Guys so majority goes to Fluidampr and not ATI

So, will get Fluidampr

 

+1 for Fluidamper

 

ATI looks like a PITA to install on our motor, but I used it on my BMW. If it were easier to install I'd go with that. But, Fluidamper because it's easy.

 

and its cheaper to.

 

The ATI seems like a better design unless Im missing something, but it also seems like a major pita to install compare to the fluidampr. In reality I have a feeling that there wont be much noticeable difference between the two in the real world.

 

I'm in the same boat as you, will be doing my build pretty soon. Just ordered a Fluidamper.

 

ATI is also way more expensive but a Fluidampr has proven to work just fine.
