ok. ive ran out of ideas to keep the egts down. im out here in new mexico and the average day time temps are 90-115. ive done everything i can think of to get my egts down. i took off the 1.0a/r housing and put the stock back on. i have a 3 inch dp, intercooler, and a 6637 with brand new filter. is there anything else i can do to get my egts down or is there something wrong. i have noticed a major drop in hp but my mileage hasnt changed. ive also noticed that in the morning there is a constant cloud of white smoke going down the road. it doesnt matter what position i have the chip in it does it it. im thinking injectors put not sure. i need to get it under control as im leaving for PA next friday

 

Have you checked for boost leaks? Just throwin that out there, that would cause higher egts...That would also cause the hp to go down

 

how do i check for leaks? my guage is reading about 12 psi all the way to the floor. i should have more but not sure as i put the 1.0 on as soon as i bought it

 

Hope this helps it's got real good pics https://www.ford-trucks.com/forums/9...ctor-pics.html

 

if i bag the the intake i should be good to pressure wash the motor without hurting anything right? its so covered in sand from out here you cant even see the band clamps

 

i would only use a water hose nothing high pressure

 

No high pressure washing, too much electrical. Build yourself one of those boost leak detectors, that will tell you where you're leak is. You should have more than 12psi at wot, even if its stock, which you're sig says its not....

 

i put the stock turbo housing on because on flat land just getting up to 60 driving like an old fart my egts 1100*-1250*

i found one odvious leak. clamp is busted on the i/c in side.

 

Ix the boost leaks and that should help alot, and then if you still are too high look into water injection to act as a chemical intercooler, and super cool you with an IC.

 

Did you get anywhere on this? I live in NM too. My PSD Exhaust Gas temps climb on up when pulling the fifth wheel around, especially on way to Santa Fe. If I downshift and take my foot out of it, I can usually climb on up in 4th, 60 + mph, and 1050 - 1150 degrees. I was wondering if I was babying it, or if it was just me. Maybe I have a turbo leak too.

 

I'm not trying to hijack this but wanted to address "jmpape" If your probe for the pyro is in the exhaust manifold 1150 is nothing to worry about, I have a steep 4 mile long hill near me and pulling 8,000lbs up that hill staying at 60mph (2000rpm) it sits at 1100-1150. my truck is not chipped.

 

1100 and up is something to worry about. its fine for short bursts but climbing a hill for 5-10 min is pushing your luck. pistons do melt. my biggest thing is that my egts are climbing like im towing a double wide around.

melting point of aluminium - 1220.58 °F


as for the leak fixed it and no help on the egts. im still only pushing 12 psi max though. it just rises a lot faster. i think it may be those stupid glowshift guages that are giving me a bad reading on the boost. i may look into a water injection kit. i had one and sold it like a dumb a$$. im just wondering if a bad injector could cause egts to rise.

 

Thanks plgebbia. My probe is in the exhaust manifold, driver's side. I was thinking like Mountaineer, maybe the turbo sprung a leak. Glad to hear it sounds about normal when pulling.

 

True about the EGTs mountaineer27, but my truck is not chipped and I am not exceding GCWR, so It will not get hot enough to melt anything, and Egts rise way faster than piston temps, and the underside of the piston is cooled by the oil jets.

 

1200* in a chipped truck and 1200* in a non chipped truck are the same temp. i understand what your saying about about piston temps and the oil jets but im saying for extended periods it cant disapate the heat. now i do understand some of the 7.3 oil jets get clogged and that leads to alot of the piston failures but i dont want to end up getting a crack in a piston from long exposures to high heat day in and day out. with that being said there is always a good reason to look for ways to reduce the egts. i maybe worring for nothing but i really dont wanna rebuild a motor when a 200-300 dollar part could fix it or something as simple as a boost leak could be fixed. i guess its that military ORM thats burnt into my brain. do the benifits out way the risk?
