    Default which harmonic balancer??

    My 565 Dart short block should be done next week & I need a balancer for an internal balanced motor. The one that Summit has isabout half the price of a Fluidampr. I know I shouldn't go cheap at this point. Just curious which way to go. Who uses what??

    Last I knew the Summit balancers where made by Pro/race. Give them a call they should tell you if they are.

That's like the 20th time he's gone by today?"

    I agree, go with an ATI.

    But..... believe it or not, about the best damper out there at controlling crank harmonics and twist is the TCI "Rattler".
    Not sure about longevity as there is a few moving parts to contend with but they work!

    I use to think the same thing about the rattler. There use to be only two dampers used in NASCAR, the ATI and the TCI Rattler. Roush used the Rattler (dah, it was developed in his shop), everyone else used the ATI. Now, even Roush cars use the ATI and there most be something to it, but it's still a damn nice piece. I have a Fluid Damper on my lawn mower and it seems to work OK

    The TCI unit isn't currently legal for Cup racing. Not sure if it would stand up to the riggors of a 6-700 mile weekend if it was. But it does work!!

    If I remember right in '97-'98 Roush used a TCI but it was similar to a fluid damper (also ran a mod version of a stock damper!). Not sure if they started running the rattler shortly after that or not (if they did it was for a short time before nascar nixed it) as I had moved on to my current place of employment after the '98 season.

    Over the years I have had excellent luck with the Romac dampner. In recent years I know there was some testing done and the Powerbond faired very well against the competition. I do feel ATI is "Top Shelf".

    these are work well also, work on the same concept as the ATI, rebuildable and tunable

    I agree with Chris...for an elastomeric type balancer, the Romac is a real nice piece. Pioneer also makes some steel SFI balancers that are relatively inexpensive.
    No moving parts for me. IMO the best going is the ATI. Be ware of cheap import copies, too. They're out there, they look really trick, and they're garbage.

    I did alot of research on this too when i was building my motor, mine was external though. I bounced between fluid and ATI and rattler for a while. End result... went with the ATI
