A drop in turbo like the KC38R would lower your egts and would be cheaper than doing the T4 conversion and SXE turbo. The KC38R works good with stock injectors all the way up to 238/100 hybrids, so If you wan't to get bigger injectors later to have more power the KC38R would work fine. Even a Garret GTP38R would work with your setup, that was the most popular drop in turbo for many years until the KC38R came along but the GTP38R is still a good turbo.

Garrett GTP38R PowerMax Ball Bearing Turbo Ford 7.3L

 

My OBS had 4:10....my '01 has 3.73.

All I can say is this....if my '01 had 4:10 rear....it would roar up hills like the 10k lbs wasn't even there. I maintain that you have an issue.

 

You may be correct. I know that I pulled a 10,000 lbs 5th wheel up fancy gap on I77. It's just under 7 miles up a 7 percent grade. My truck held 68 mph all the way to the top in overdrive at 1200,egt. I felt good about that. Truck runs as good now as ever,but it will not pull this toy hauler up a grade at that speed. I think it has more wind drag than the 5er had,and I just run out of power. If I drive 55 or 60 , it maintains that ok. Less wind drag. The 2 trailers weigh about the same.

 

 

Please report back if you change turbo and let us know what you think. It will help others as well.

 

 

Yes Diesel and gas engines are the opposite when it comes to adding fuel and air, adding more fuel makes a gas engine run cooler but it make Diesel run hotter, adding more air has the opposite effect on both engines.

 

OK. My rig only has 179K on her. Pretty positive I have stock injectors. I have GTP38R with maybe 30K miles on it with newer stock wheel with maybe 20K on it, bellowed uppies, Riffraff Boost Fooler, UVCH, 4" Stainless exhaust, 3.73 rear end pretty sure, Auto trans, Stock Trans cooler, FPx, HPx, UVCH new wires and plugs, Plenum inserts, newer boots from Clay, Hydra chip with Stock, Tow 40 hp, and Tow 60 hp tunes, and DD tunes.
I tow a 27' 10K lb. 5th wheel.
When I tow up 6% grades at 7K ft, I have to take her out of OD, and keep her at 2300 RPM to keep the EGT's below 1200. Only getting about 45 mph up the 3-4 mile 6% hill.
What tune you guys using to get that kind of boost and lower EGT's?

 

The altitude is what is getting you.

 

 

What Brad said.

 

Handy1, we all hope you find your path and are very happy with your choice. Keep us updated.


I know Corey (CNC Fabrication owner) on a professional level and have spoken to him many times on the phone. He makes some great products and supplies us 7.3 owners with great products so we don't have to search the web for them.

That said, I have a very hard time believing that the picture posted above originally by Corey on FaceBook and then again further up in the thread by BlueMax65.

I have a couple of issues with the photo and they are as follows.

1. The grade does not look like much of a grade to me. It looks more like a long rolling hill like we have in the low country of SC where it is a steady incline for a mile or so. I would consider a grade something like in TN or out west.
2. It is difficult to get a good representation of the hill based on the single photo because we don't know the angle and where the driver is at in the grade. Are they in the valley just starting up the hill, are they in the first 1/8 mile? We just don't know.
3. 729 degrees pulling a 14K lbs 5th wheel? Where is the EGT probe located at on the truck. Is it in the manifold like most of us have it or is it in the downpipe which would indicate the reading makes more sense but not a true reading of the EGT's.
4. My truck (not all trucks are created equal) will hover around 600-800 EGT when driving 65 MPH in 5th gear (ZF6 manual) unloaded. Again, the 729 degrees is hard to believe with all things being equal. I am not saying it is not true, just have to see it in person or in a video that has good representation of the load behind the truck and the road/grade/hill it is traveling on at the given speed.
5. We cannot see the speed or RPM of the vehicle.
6. Is there a trailer behind the truck and if so, how do you know?

Anytime a turbo comparison video or image is posted, there should be all sorts of qualifiers provided. Tune selected, who the tune is written by, injectors, speed, RPM, manifold vs exhaust back pressure, etc...

Again, I am not saying that the picture is not real, I am just saying that I am a person that has to see things to believe it and this is not seeing anything other than a colorful display of numbers at some random point of the owner driving the truck.

People lie all the time about what they have done or what they are doing to make themselves feel better about their actions or choices, especially on the internet. It is much more difficult to swallow your pride and admit that you are human and made a mistake in judgement and move on from that. I make mistakes every day, it happens and I am not afraid to admit it. How we move forward or learn from those mistakes is what sets us apart as individuals.

 

Looks like they have good oil pressure and battery voltage!
