blowing out turbo coupler
I posted about this problem a few months back, and it is still an issue.
The coupler that comes off the small turbo and links with the down tube going into the intercooler keeps blowing out. I mean a 3" hole in the side style blowout!! Last time it was on the way home and just a few miles away, so I limped it back. But this time I was 225 miles from home, but luckily 5 miles from the town we were heading. Had to get a tow for the the 5th wheel the last 5 miles, but limped the empty truck to our campsite. I next day aired a new coupler, installed it and heading on our way home. 5 miles is all this one lasted!!
It is always under heavy load, towing 14k. And it's always on a long hill at the top. I try to keep my foot regulated to 1250-1300 max egt's, and don't run over 1350.
I had a Banks intercooler, so here was my concern. While that was very sufficient when I was running a single turbo, is the compound system producing too much cfm, causing a build up of back pressure that blows the coupler on long pulls?
I had to get my wife home for work, so I had a BD Performance intercooler shipped to me and I installed it before coming home. I left my trailer at a storage facility and just got home. Obviously didn't have any problems on the way home (other than trying to keep her under 100 mph!!), she wants to run!
