Dear RV builders,

I just completed my silencers and the noise measuring procedure for my RV8. Silencers
had been built by myself, noise tests had been performed by MT in Straubing.

The silencers are similar to certified silencers here in Germany. Sometimes the
installation causes increased cylinder temperatures. For the moment, I can't
acknowledge this in my case. My temperatures vary between 310-330=B0F, the oil
temperature is steady at 195=B0F.

With the installed MT propeller MTV175B59, the noise level during go around (Vy
95 KIAS, full power, RPM 2500) is 65 dBa (ICAO). This is below the limiting value
for my plane, however above the maximum value for the low noise category.

Best regards
