Project Golf R MKVII: Fluidampr Test


Here we have the stock and Fluidampr crank pulleys side by side. The stock elastomer unit is definitely fine for normal stock power levels and will work well for many many miles. The Fluidampr looks like it is made to the highest standards of quality, and it is much “beefier” than the stock unit.


Here is a look at the indexing grooves in the back of the factory crankshaft pulley. This design was very easy to remove. Simply remove the main bolt and it comes right off.


The new Fluidampr install is nearly complete. The pulley is in and belt is back in place. The same size belt will fit with the Fluidampr. We reused our stock belt, as it was in good condition. Howard finished this job very quickly so we could get the car back on the dyno for some follow up testing. Our results definitely surprised us! 


Here we have our stock baseline run compared to our final run with the Fluidampr crank pulley installed. The baseline run is the red plot and the black plot is the Fluidampr run. Though the increase in power across the entire powerband caught us a bit off guard, the gains at peak power were extremely impressive and made us all take a double take! Almost 7 wheel horsepower at 5,900 rpm and 11 foot pounds of torque at 3,150 rpm.

The dyno plot pictured above shows a comparison of a baseline run and a run after the Fluidampr install. We were honestly not expecting a big difference in power from the install of the pulley, so what we saw definitely surprised us. The ambient conditions from the first test to the second test were identical, and the oil and engine temperatures were nearly identical. We know the oil temperature and ambient temperature can make a difference between runs, so we were sure to eliminate those variables. The gains in power across the entire powerband are the result of the science behind the Fluidampr design at work.

The baseline run yielded 223.0 wheel horsepower at 5,900 rpm and 233.8 ft/lbs of torque at 3,150 rpm. While our engine with the Fluidampr crank pulley produced 229.7 wheel horsepower and 244.8 ft/lbs of torque at the same rpms. Those are gains of 6.7 wheel horsepower and 10.6 ft/lbs of torque! What's more impressive were the max power gains of 12 wheel horsepower at 5,600 rpm and 19 ft/lbs of torque at 3,650 rpm. Truly very impressive and surprising numbers.

As stated earlier, the main goal for installing the Fluidampr crank pulley was to lay down a solid foundation to maintain reliability while we embark on the road to extract more power out of our Golf R's powertrain. The solid performance gains we experienced are simply a very welcomed bonus! The team over at Fluidampr definitely knows what they are doing and we can see why so many engine builders use their products. Fluidampr has taken the knowledge and experience they've accrued over the years and have applied it to many different platforms. So if you've been bitten by the power bug and are looking to increase the performance of your build, they are definitely worth a look!
