Help / Happy to be here!

Glad to find this forum, I feel like a kid in a candy store! I have a question for some of you. I own a 99.5 F350 CC 4X4 drw lwb 7.3 6spd std with 261,000 miles and pull a 20' gooseneck trailer that weighs between 14 to 15k when loaded. My exhaust temp is 11,000 or better when climbing hills. I've allready cracked & replaced the manifolds once while the superchips programmer was on the lowest setting. I uninstalled the tuner and went back to factory settings. Checked the intercooler and air filter (both are free and clean). Now I am still heating up when pulling hills and have NO power or speed. I am running a MBRP 4" exhaust and Airaid filter and box. What can I do to get my exhaust temp under control? My diesel mechanic recommends a ball bearing turbo or buying a bigger 450/550 series truck. I really like my truck but if I go with the better turbo will this stress other componets on the truck? Any help or advice from you guys is greatly appreciated.

First off welcome to the sight. For your problem I might recommend water injection. It will lower your egts. You can run it only while pulling up them hills to keep your egts down. There are members on here with this set up. I am sure they can give you more info then I can about it. As for a ball bearing turbo. I really don't know if that would lower your egts. I have not dealt with them.

Hello and welcome to Powerstoke.org.

I hope you meant 1100 degrees and not 11000. I believe 11000 would have pretty much melted everthing under your hood. Now, as for lowering it, preventing future failures... actually 1100 degrees isn't really a horrible number. But there are things you can do to lower that... Have you done any kind of intake mods? A more free flowing intake system will allow the turbo to put cooler air into the engine to start with, and will lower egts, just steer clear of the K&N Filter.. it flows great, but doesn't filter very well. If that doesn't get them to an acceptable level for you, you might consider the water injection.. or a different intercooler. I personally don't see how a different turbo will help.. maybe I am wrong.

Welcome to the forum!
Sounds like you "may" be over loading it but not to the extreme. Maybe your trying to drive it to fast up these grades when your over heating her?
Upgradeing to a 6.0 (more HP and tq) or at least a newer 7.3 might be in order for ya.
Again, welcome!

-- you might want to look into a proper chip for what your doing, talk to Jody at DP tuner, or Dennis at ITP, I noticed a drop in EGTs after I put mine in.

Welcome to the Forum!

When EGT's get up lower your gear and back off the go pedal. The load you are carying is not enough tobe causing those temps alone. It may be driving style. the SCT on tow mode should be ablr to keep temps low enough.

If changing driving habits doesn't help, you could go with lower rear end gears, like 4.10's to help. It would be cheaper than changing trucks.

Also, where is your temp. probe mounted? If it is in the manifold, 1,100 degrees is OK.

You can also put a 6.0 intercooler on it, they are a little bigger, might help a bit.
