I had to run these for 12 hours straight under load ;D
The customer bought 4 of these monsters. And they are just for backup power !!! The white trailer off to the side is the loadbank I used to test the engines. The expensive looking muffler bracket was used to keep the neigbors happy. They are very loud without the muffler on ;D

A little bit closer view.


The original pictures were over 400k in size. Getting them down to 100k took it's toll on them !!
