Fluidamr LS1 underdrive pulley
Fluidamr LS1 underdrive pulley Any experience with these? I read a comment by Sam Strano and he seems to like his a lot. Upon further research it also appears it's a respectable amount lighter than the OEM unit (for what it is) Also, the balancing construction is fluid as well.
Just wondering if anyone has this on their car?

I chose it over the ATI pulley, because there's nothing to wear out.
IMO, it's worth the cost.
Besides less shake, did you notice anything else?
Well the fact that you claim it idles smoother due to less weight which makes sense, I think really makes it a quality unit. I might consider this.
IMO a UD Pulley is a UD pulley the only difference is if it's 10% or 25% to me you can spend $200 on a SLP or similar and spend the other $200 on something else. After belts and all with that pulley your looking at over $400 but that's just me.

I run it because it is a true harmonic balancer and not just a smaller diameter (UD) pulley. It does run smoother as it reduces torsional vibration, resonance, and wear on the mains. Definitely a quality piece. You get what you pay for.

I used napa serpentine belt 25060775. It was a little snug so could probably be a hair longer. I think the next size up is 790.

Thanks man, I was just about to ask on the belt size too. So 25060790 is what i'm looking for than.....

Still if I was going to drop FD money I would go ahead and nut up for an ATI. ATI has been on EVERY LSx all out racecar I have ever seen..
Well based on what I've read on here, the ATI is just a UD pulley. The fluidamper unit is not as much of a true UD (10%) but it is a true harmonic balancer which I really like the idea of.
I have one on my 408 and it's a great piece. I had an ASP pulley on the stock shortblock and spent the extra money for the Fluidampr and it's worth the upgrade. I don't have to worry about any harsh harmonics when revving this motor now.
Like mentioned above, there are pulleys whose purpose is to underdrive and there's true dampners. It's all a matter of what your purpose is. The Fluidampr is 10% underdriven, but does it's intended job much better.

This is what's on my car (with an 8-rib blower pulley in front of it) - it's not a UD pulley at all, it's OEM belt size for serpentine and A/C belts, and is a true harmonic balancer.

STRIKER FYI....
The ATI is a true damper dude. All the big dollar boys wouldn't run it and risk their crank and bearings if it didn't do the job.... From there website...
The only damper designed exclusively for high rpm performance engines.
The patented ATI Super Damper is the only damper designed exclusively for high rpm performance engines. The proven elastomer design is actually two dampers in one: a 4'' diameter and a 7'' diameter damper contained in two shells that bolt to the crank hub. The inner and outer shells are available in steel and in aluminum to contain the steel inertia weight. The inertia weight has eight computer machined grooves to retain the proper durometer O-rings (dyno tested for each application), and installed at ATI. O-ring life has been tested to over two million cycles in Winston Cup competition and 10 years in drag racing engines. The unit is rebuildable to new specifications by installing new O-rings. Extensive dyno and on-track testing has proven the Super Damper far superior to all other designs, especially on engines that turn over 6000 rpm, and is used on nearly 100% of all Winston Cup engines. Shells are black zinc chromate finished, with computer controlled, laser engraved 360° timing marks. Exceeds SFI 18.1 specs.
If you want the best ATI is it period.......
