Background:
In the last post, I discussed installing a Fluidampr harmonic damper and the resulting changes to noise level and vibration inside the cabin.
In the chart below the blue line is without the Fluidampr and the orange is with the damper installed.
This chart shows the changes in sound level inside the cabin.
Parts swap:
The next parts being swapped are the engine and transmission mounts. The car has been equipped with the BFI Stage 1 mounts for a while and I have now installed 034 Density Line mounts.
As before, the vibration at the dashboard is measured using an Accelerometer app on my phone and the values are compared with the previous two configurations.
The amount of vibration at the dashboard is further reduced with the change to the 034 density line mounts.
Recording the in-cabin sound level and comparing it with prior configurations shows that the sound level also decreases, as shown in the chart below.
Conclusions:
Installation of the 034 Motorsport Density engine and transmission mounts led to a decrease in vibration measured on the dashboard and sound level measured inside the cabin. These decreases were relative to a previous configuration using the BFI Stage 1 engine and transmission mounts.
All things considered which one do you prefer?
The 034 mounts. The reduced vibration and noise is noticeable.
