There's been intrest in the Fluid Damper (FD) for the 6.5's again. So, I got together another group buy.

I need atleast 5 committed buyers (more is better).
Cut off is 15nov12.
Will be drop shipped from FD.
Your choice for mechanical IP (DB2) Part #800191.
or electric IP (DS4) Part #800141.

Cost $435 + $15 shipping in USA. This beats the competition by $20
Its not on my web site so PM me and post up here if you would like one.

Part #800191
fd for db2.jpg

Part #800141
fd for ds4.jpg

I can also offer a GB for the Dmax trucks if there is an interest?

Heard bad things about putting these on a Dmax, I am open to success stories on the Dmax.

I do need one for an db2 and ds4

There fine for stock power levels and stock RPM's, but if you start turning them up many have broken cranks with them as they are 14 pounds heavier than a stock DURAMAX balancer.
 
I have read that these things are supposed to be the best. Has anyone ever experienced a crankshaft failure with one installed on a 6.5L?
 
My name is Ivan and I work for Fluidampr. I will be more than happy to answer any questions or provide FACTS about Fluidampr products.

Fluidampr is not 14 pounds heavier than the OEM damper. 6.2/6.5 Diesel OEM weight- 12 #'s, Fluidampr weight- 18#'s which is 12#'s of rotating weight. Rotating weight is what is felt on the crank during operation, this is due to the free floating internal inertia ring used with viscous damper technology.

Fluidampr dampers do not break crankshafts. I have no knowledge of any 6.2/6.5 engines having broken crankshaft as a result of Fluidampr. Our parent company Vibratech TVD invented viscous torsional dampers in 1946. In addition we are OEM suppliers for many diesel engines. We also supply to top engine builders around the world including Banks engineering for their GM engine builds. These OEM's and engine builder would not use Fluidampr if there was a direct relation to Fluidampr and broken crankshafts.

I know there has been crank issues with 6.6 Duramax engines. However, I am very active with GM engine builders and have had many conversations regarding this exact subject. The crank issues are due to the design. This engine is externally balanced and had a fairly long cranksnout with the counterweight on the damper on the end of the cranksnout. It proved to be sufficient for OEM set-up but when pushing crazy H.P. and Torque at high RPM it proved to cause occasional crank failure regardless of damper. After many discussions we are now looking at manufacturing an internally balanced Fluidampr. Obviously this will require removing the OEM crank set-up and replacing it with an internally balanced crankshaft. We are still in the early stages of developing this damper.

Fluidampr dampers are used in applications from daily drivers, to tow rigs, to high performance pulling and drag machines.

Again, I am here to answer questions you may have regarding Fluidampr products, so feel free to ask.
 
inc4203, do you know how many 6.5 dampers have been sold? and how many have ever been returned for warranty.
Can we get your first name?
Thanks for the info.

Edit: Sorry just reread and see your name is Ivan, thanks.
 
Although I cannot disclose exact sales #'s for a particular part. I can tell you that we have sold multiple hundreds and the combined warranty rate for the 6.2/6.5 Fluidampr part#'s, 800141/800191, is less than a half a percent (.5%). And again, none were associated with a broken crankshaft. Over half the claims were due to ordering the wrong part#.

Ivan, if you have time post up in introductions so we can welcome you to the truck stop properly! :thumbsup:

Thanks for the info Ivan. And, marty is right you would get a big welcome. I'll give my welcome now.
:welcome8:
Now back on topic.
 
My motors seem to have a harmonic vibration at 1200 rpms only. Any other rpms they are perfectly smooth. Would a Fluidampr correct this ?
 
Introduction posted... thanks for the tip and the welcome!

6.2- As there are so many factors that can lead to vibration issues (worn elastomeric damper, performance upgrades or any change regarding the rotating assembly), it is hard to know what exactly may be exciting your vibration issue at the 1200 rpm range.

Being a V8, the worst harmonics usually occurr on the 4th firing order at a given rpm. Now to find what frequency the vibration is occuring at we must calculate the following - F = N (rpm) x O (order) / 60 (cycles per second). F (hz) =1200 x 4 / 60, In this case F=80 hz and is where you are having a vibration issue. An OEM rubber damper for a 6.2 targets between 155 and 200 hz (I know this because I have the OEM damper drawing in front of me). Here is where the problem lies with rubber dampers. Rubber dampers cannot combat frequencies outside of what it was designed for. OEM's determine where the worst harmonics will occur based on OEM set-up and target that frequency. If changes are made or the rubber damper is worn changing where the worst harmonics are occuring it renders the OEM unit useless. Due to Fluidampr's viscous technology it is able to combat harmonics at all frequencies across the entire rpm range. OEM's use rubber dampers from a cost standpoint. It is also important to point out that almost all OEM heavy duty diesel engines (high $) use viscous dampers.

To answer your questions- yes the Fluidampr should help with your vibration issue. However, depending on the root of the vibration, it may not be completly eliminated.

OK, when we have 4 more I'll send out invoices.
Thank you.

Thanks for that. Nice to have tech support right here.
 
I'd like to have one, but...money, you know. If you get 4 and need another, I could be forced to do it just to help everyone else out!:hihi:
