What is everyones thoughts on dampners? I figured since I have to replace my water pump I might as well put an ATI or Fluiddampner on. I want to try one out to see if I can knock down some of the vibrations at idle caused be my single mass flywheel.

You might want to check if they recommend installing one without balancing the entire rotating mass with the new dampner on. It may cause more problems if you do not.

How can you feel or hear anything with that loud clutch of yours?:D

I believe they are made by fluiddampner. But they are made to Guy's specs. Not theirs. And I think they are lighter than fluiddampner's. And like TexasMax said. Make sure you don't have to balance the whole she-bang.

The socal dampner is made by ATI. you dont need to rebalance the rotating assembly since the ATI/socal balancer has the same amount of counterweight as the stock externally balanced damnper does.

Huh never thought of that. I'd just heard of guys with single mass flywheels putting them on and having it quiet them down a bit.

It is embarising as hell at how loud it is.

All I know is my balancer threw off the balance of my rotating assembly somewhat. On my first build, I had forgotten about ordering a damper from Guy, and I had my machinist balance the rotating assembly with the stock unit. When the SoCal damper arrived, he put it on, and the balance was off enough that he had to add some weight in some spots and remove some weight in others. Don't know by how much though.

Our dampers are definitely NOT made by Fluidamper!

The reason the Fluidamper tends to calm the idle down is it's mass. It weighs considerably more than a stock damper. :eek: Which will actually rob you of power during acceleration and not neccessarily dampen the engine harmonics that occur at elevated rpms

Some shops balance cranks by removing weight from the damper and flywheel. This presents an issue when the need arises to replace either of those units after the engine has been assembled. We prefer to do all of our weight removal from the crankshaft to avoid this situation.

Our dampers are pre-balanced to mimic as close as possible the factory weights, which means you may install them on an existing engine without the need for re-balance assuming the damper it is replacing is virgin.

That being said, when having an engine built, it is always best to supply your engine builder with the damper you are actually going to run when he is balancing your engine. That way he can dial it in to perfection.

My apologies. I couldn't remember for sure who made it. I know that they make some and so does TCI, but not for us. Didn't know ATI made their own, thought they had someone else make them. I wouldn't mind seeing the Rattler on our trucks. But that is just me. Most don't like them and think they are crap.

So I would be fine running one of your dampers Guy. And what is your thoughts on it helping my noisy clutch.

Yes you would be fine, however I don't think it will help your noisy clutch problem. The noise is a result of the normal oscillations of the engine at an idle.

You could try raising the idle speed a little to see if it helps with the noise.

Okay thanks Guy. I have noticed that if you idle it a little higher the noise goes down. I just figured something else in the harmonics was being effected.

Guy, at the time, I know my buddy that was doing my machine work told me how much difference it was in the weight, but I can't remember for sure. I want to say he said it was somewhere around 50 grams heavier. Does that sound right? How would that much weight change things?

50 grams is a lot! :eek:

I may have to talk to him to get the right info. I know at the time he called you about it. This was a little over a year ago. Would have been a fella by the name of Jake Robbins from J-RAM Machine Shop out of Payette, Idaho, if any of that sounds familiar.

I don't remember the weight, however I do remember the call because he is the only one that ever criticized the weight. I have been unable to duplicate his findings. :confused:

Guy,
What about those people that have removed wieght from the dampner and flywheel?
