Was poking around and found an article on ATI Super dampers. I had a fluid damper on both my dragsters and had no ptoblems. Anybody got opinions or dyno data supporting one or the other?

ATI is the most popular here used.
TCI Rattler is my Own Choice.
John Kasse used in Engine Masters many times and won lots of money.
He has won more than any other in that contest history.
almost 60% of the articles, Ive read through show the ATI has a minor advantage,
Ive generally built engines using the top tier version fluid dampers and Ive not had any issues.
from an engineering stand point I like the fluid damper concept of a heavy ring suspended in a thick viscus, silicone base, grease,
I can easily see it effectively, absorbing shock loads effectively over a wide range of rpms
keep in mind both companys sell a much less expensive damper line,
so you need to ask questions, and not assume all products from a manufacturer are identical or designed for your application.
that would be like saying chevys SUCK, because you bought a chevy VOLT..... if you were looking for the speed and handling of a corvette or or carry capacity of a c2500 pick-up

When I was reading about the ATI damper I got the impression it had mounting holds for blower pulleys. I have a huge aluminum adapter for my pulley. It also said the fluid damper was better below 7k rpm and o doubt I’ll ever see that rpm.
Are you referring to one article or several? How about a link to that article if you can remember?

Rick I just saw an advertisement for super damper and never heard of it so I googled that and read several articles including comparisons with fluid dampers and rattlers.

I have seen Fluid Dampner get Ruined Dirt track Racing.
Big Rocks hit the Fluid Dampner and put a big dent in it.
So inner ring no longer floated around.
Be rare to happen on the Street but it can happen.

No.
That is dirt track racing.
Hidden big Rocks get dug up from the track undersurface.
Car up front digs up and throws into the dirt track car behind.
Near all Run ATI Super Dampner.
Seen one time a Defective Small block Chevy Fluid Dampner on the street.
Laser weld failed.
Leaked out all the silicone fluid.
Summit covered the warrenty.
I prefer to avoid.
Stock.
ATI SFI.
TCI RATTLER SFI Pendulum style balancer dampner.

The high horsepower dirt track cars dig down 1 -2 feet into track surface after race night Grumpy.
I don,t care where the rocks your bouncing off your engine came from,
if the part fails after being smashed with ROCKS its hardly defective, engine part design.
no engine is designed to be hit from the outside with large rocks or projectiles impacting on it.
how long would you last if some moron started beating on you with a large jagged rock!
