Soft Mounting Benefits (was: Tonight's Dumb Idea...)

[EHaury at aol.com]

An extreme example of engine vibes. At the lab we had test stands fitted with 
large truck engines (Mack, Cummins, Cat) that ran industry standard lube 
tests. These things are 6 cyl, around 350 Hp and 1000 LB/ft torque and ran flat 
out. Someone solid mounted them to ensure driveline alignment. Nothing could 
keep them from breaking the mount adapters, which went from 3/8" to 1/2" to 3/4" 
steel. Eventually stock (soft) engine mounts were fitted and never broke 
again. We then spent a lot of time fixing broken (6" dia) exhaust pipes. Sound 
familiar?
