Cummins out towing a Dmax vid.......
I picked this up on another forum I'm on and couldn't resist, even if it means I'm picking on myself a little. lol
Enjoy the pulling power of the cummins vs. Dmax. Also the retardedness of the Dmax owner. Seems most guys I talk to on the Dmax forums have a firm view that your engine coolant temp has nothing to do with your EGT's. A stock LLY Dmax WILL run 1300-1350* pre turbo with a lot of throttle. I.E. a heavy load uphill. Well when you run 1300-1350* EGT's for 5-10 minutes strait then yes you are going to overheat like crazy. You MUST have a better intake, especialy for an LLY Dmax, and a free flowing exhaust. Then with 1050-1100* EGT's overheating shouldnt be an issue. Well most of those guys think I'm crazy and you should be able to run 1350* all day and not get hot. ![]() http://videos.streetfire.net/video/L...htm#commentTop

HAHA, The D-max will make power I dont deny that, but I've known all along using that power was the challenge! I don't feel bad for him, he bought a grocery getter and thinks its a work truck.

Seen this video a long time ago. There have been a few threads about it, but I think they were all closed.
I still wish it was an old 1st Gen that he couldn't keep up with. ![]()

This is old news. TXChristopher joined DTR and made some comments here on this thread listed above. He is the guy talking in the video. I believe he sued GM and won and used this video in court. ..

Yep, Chris won the lawsuit against GM.
The issue was do to with the Duramax cooling system, not EGTs. Would overheat during towing and go into limp mode. A poor design for that model version cause airflow issues though the cooling stack up. I tow over that same stretch of highway and my Cummins would get to around 210-215 degrees during the summer.

I'm no mechanical engineer but you would think that would starve the engine of air. Which in turn would make the VVT close the vanes more trying to build more boost and get more air into the engine. But without being able to draw more air in the vanes closing would only create more back pressure, more heat, and higher EGT's. I wonder if anyone has ever put a good flowing LBZ turbo inlet and a cold air intake or an aftermarket non VVT on an LLY and overheated it. |

The fellow that sued GM has a fix out that is a secondary rad mounted down low to accomodate extra cooling. We were wondering if the LBZ rads were that much bigger or what, but you could find a LBZ rad at the wreckers and upgrade to that.
