Fluidampr Internally Balanced Damper
 

Another cool products was released today from Fluidampr. Pretty interesting stuff. Testing revealed consistent performance gains above 4000rpm compared to both an OEM tuned elastomer damper and a lightweight crankshaft pulley. The lightweight pulley tested provided no torsional vibration protection and left internal components susceptible to potentially destructive high frequency vibration between 5,000 - 7,000rpm.

This may be a good investment for people running built motors, or cars that see a lot of high RPM track time. Good piece of mind mod.

I thought they released this like 6 months ago or is this revised.
I would also like to know if the graphs are FA20 specific because those TQ and Power numbers do not look right

I am not sure what dyno they used. I thought it looked weird too, but they started the graph 4k rpm, so the torque dip is not visible.

Thank god someone else posted this! People on here will have a field day with the theory of boxer engines being "naturally balanced" and are convinced that light weight pulley will not harm their engine! Thank you. I got flamed hard for posting a thread for a brand of performance crankshaft harmonic balancers.

I have one of these for my GTI I'm building the motor on, it's a nice product for sure. Not sure how that translates to the boxer motor though lol.

+1 that graph looks off.. and they need to show the entire RPM range unless they are hiding something.

@MAPerformance is the frequency graph for the FA20?? Or just some graph they have laying around?

That one was an actual FA20 from either an FRS/BRZ that they tested. They also released one for the Evo X, and had a specific dyno for that vehicle as well. I reached out to them to see if they can give us the full dyno graph.

Got a response back with a full dyno, as well as both waterfall plots of the torsional vibration testing, which measures the overall twist (peak-peak) resonance of the crankshaft running the Fluidampr, OEM damper, and a lightweight pulley.

The car tested was a 2013 FRS with an intake, single exhaust, and a tune done at R/T Tuning on a Mustang Dyno.

No wonder the initial graph started at 4000... didn't want to show the drop from 2800 to 3500 RPM. What's going on there?

Probably because it's heavier than the stock pulley

Would someone be so kind as to make comment on the 3 waterfall graphs? I don't know if any of what has been shown is good or bad.

I don't know what the "orders" or the "peak vibration angle" is referring to.. it might have to do with the sensor that they are using to measure the data.

Most likely correct. He did mention that they typically focus on high RPM performance since most customers use these for high RPM use, mainly track cars. But yes, very interesting indeed.
