Na i am getting good with running the 275 tune and towing, there is a art to driving it tho thats for sure.

 

Unless you really backed off to keep your EGTs down I fear you would suffer the same demise the Dodge did.

I don't see where the 6.4L is built THAT much better than the Dodge where it couldn't handle 50 HP more and the 6.4 could handle another 275. I may be wrong, what have you done to your motor to keep it together at sustained WOT like that

 

I just got to keep it way up in the RPM range and I am golden. When ever I tow the 20K toy hauler I run in 275 now. Most I ever see for Exhaust temps is 1,500.

 

unless that "6.0 or 6.4" has a better cooling system then the dodges 5.9, then i dont know how your motors still running.. Unless you have rebuilt your motor. Hows your motor holding up nick?

nick, alls i know is that you have a "built" 5R110 in your F450. But is your 6.4 built or stokc?

 

Here is a PDF with the results of our testing from this meet.

I forgot to post this update from Monday in this thread.

An update on my neighbor’s Cummins Dodge. He started it up this afternoon. Started a little harder than normal. It was blowing a lot of white smoke. Smelled heavily like fuel and had knock/tick sound. We shut it down and did a scan. Came up with P0217 (Decreased Engine Performance Due To Engine Overheat Condition) and P0483 (Fan Speed).
It got loaded on a trailer and should be torn into tomorrow. My neighbored called two different Cummins guys and got two opinions. One thought one of the cylinders was burnt (he thought number six would be the likely candidate) and the other thought an injector blew a tip. I guess we’ll find out in the next few days.

@ Matt[ I EAT HYBRIDS]----What kind of exhaust you have, it sounded pretty throaty. I run a 4" turboback magnaflow system w/ cat still on it. It sounds nice nut not as good as yours.
