Done the search... read it all!
Get the big plus for pullers going to 4000+ rpm.
Get the benefits for 6 speeds w/ dual disk clutches.
But for an automatic, shifting under 3500 rpm in the 1/4 mile ... or daily driving at 450-475 hp??

I'd especially like to hear from 24v Auto owners that have the Fluidamper.....any benefits on the street or at the track?
Glad you have it? Would you buy again?

I do not have one, but i talked to a representative at the FASS Diesel Nationals and he said it makes a difference even if the truck is stock. Now is the part whether he was feeding me a line to buy it or was serious. I could kinda see how much better it would be on balancing the engine throughout all the rpms. If all else fails you could call and talk to them about it.

I hope this helps some

I have the mindset of not turning enough rmp to warrant the expense.

Have to buy a pin kit, which is an extra dowel pin that you stick in the crank shaft. Only if you want anything above 3k.

not worth it...

how many years were we running the dog snot out of these engines without them?

get it knowing it's piece of mind overkill not looking for any real benefit

The fluidamper type of harmonic balancer is stock/OEM equipment on many Cummins applications.

And I do run one in the quarter with my A518.

Gary Emerald

absolutely... all of our stationary engines run silicon fluid dampeners... my point is that he will likely see zero gain/difference on his truck

There will be a difference, but not the kind of difference that would make a difference in ET. Maybe longevity would be improved for a truck that's being beat on. I am running a fluidamper and the difference can be heard the moment the truck is fired up. Just less vibration and a different noise from the motor. If cummins is using similar technology on their higher hp engines then it would make sense to do the same on a bombed truck. JMHO

Thanks David (and others)!
I'm not buying into the "more hp/tq" that they claim..... but Cumming using them on all marine engines got my interest.
Smoother running from idle on up is what I was hoping to hear.
Also, have heard that many factory units don't look real healthy when replaced. What mileage did you do yours? Condition?

Does anyone have a part # for the Cummins silicone damper? Are there different specs between marine and stationary engines? Is there a Case # for the same application (Case parts are usually cheaper for the same piece)?

I agree that a FluiDampr can't hurt - especially to increase engine longevity & reliability, and it'll help performance as well - although you may not notice several hundred $$$ worth of difference.

I talked to a guy here that had swapped in a Perkins engine in his Ford. Well the engine didn’t have a balancer on it but he ran it any way......in about 10,000 miles he had a broken crankshaft. (I was looking at the engine for a project but didn’t get it) Point of the story is that the balancer does a job....and i feel that one that can adapt to changing vibrations frequencies would help with the life of the engine.

Dan, where's my CAD file?
Or blueprint?
Or Paint rendering?
Or shop drawing?
Or crayola special?
Or Etch-A-Sketch?
Maybe even a vague description of possible dimensions & components?

Where's JH when someone needs him??? Since he took on the new position at their tech center he would likely be the most qualified guy to ask. RJ, if you can track down Justin I'd bet he would have an answer for you with Cummins' own research to support it.

Who is using them? I was over 150k miles when I changed mine and the only thing physically wrong with it was caked on oil from the puke bottle

OMG!

You're busted on this one - I know how far the G is away from the S on your keyboard...
