Here comes another one: I was looking at the properties and operating maximums for
materials used in the Berry mounts. The Neoprene has max. operating temperature
limit of 200 degrees F. and Silicone 300F. I don't know if that could be a problem
since the 2200 series mounts are Neoprene? I will call and see if they make them
from Silicone also.
As I recall the silicon option is real expensive.
Another good reason to put them in the firewall. My hat section mount
as shown on the ACRE NL web site has them mounted in the steel hat section
cross member which is several inches away from the engine
and which conducts less heat than an aluminum plate under the engine.
Another advantage of the steel cross member is the torque loads
on the rubber mount are lower so the vibration transmission through the
rubber is less.
