Avg Egts with Hybrids and 38r

[CSIPSD]

always seemed to run a hair hotter than the other truck around here. When i put the 35 toyos on it i saw a rise in the egts. Yesterday running 80 it was sitting at 5 psi and 900*. My dads excursion with leaky uppipes pulls the same load a lot cooler. He doesnt have a lift though, only a level with 285's

Just took this as I'm driving home..

hard to tell what temps you're running. looks around 700? If i dont have any boost or drive pressure leaks, What else do i need to check and eliminate? If i could get a list of things and check them off itd be really helpful

Haven't read whole thread but have you tried changing the air filter?

 

[lariat 7.3]

uhhhh nope... lol. Ill try that. Ive had a couple different 6637's on there in the past and I didnt noticed anything. But ill try it

I take people maintaining their vehicles for granted when they ask questions about performance issues. My bad, but I assume everybody is proactive on a enthusiast site.

Im glad you said that....

i maintain this thing like its my child. Just because I haven't tried a new air filter doesn't mean that i don't "maintain" it. I live in an all paved area so the filter sees very little air born debris. Filter doesn't have more than 15K on it and i constantly check the intake tube for dusting and such. Its not like i just have a filter sitting there covered in 4 lbs of dirt and crap........

Filter isn't the problem...turbo is get a bigger turbo like a modded H2e and then try some different tunes or tuner

Not saying the type of filter is the problem saying the filter could be that dirty. Don't tell people that its not the problem when you don't know if It is or not, and he's try'd different tunes.

15k miles even driving dirt roads won't clog a Donaldson.
Bean tested a Filthy Tymar kit on a dyno..made the exact same HP without any filter.

Maybe your gauge or thermocouple reads higher on average than everyone else's too. Wouldn't it be funny if you are worried about nothing, lol? There are a lot of variables that can cause a situation such as this.

Not egt related but my autometer trans temp is fakked. It doesnt do anything. Gets to.140 and hangs there.

Id make sure the probe is.good before I worry. Thats whats nice about a CTS, you can bounce numbers off one another.

How far is your pyro inside the manifold?

I always thought my autometer tranny temp gauge was screwed up, cause it always read low. The needle hardly ever moved, until I pulled a heavy load in 100 degree temperature in traffic with no air movement and high humidity. That gauge wrapped around to 200 degrees or better with ease and I started to trust it more. 140 degrees seems about right to me, depending in where your probe is. My boost gauge on the other hand, liked to get stuck on 0 till I would give her a tap or two. I guess the moral of the story is to not always trust your gauges. They can fail like anything else.

My v10 doesn't need them, lol.

I know you're saying the filter can be dirty TYCORR, I'm just saying I've ruled out that variable. I've swapped filters in the past. EGT probe is about in the middle of the manifold as far as depth. I'd be relieved if thats all it was, haha. Is there anyway to pressurize the exhaust side of the turbo?

 

[neverkickn]

Yeah, you need a plumbing cap that you can slip over the turbine outlet where the downpipe connects. I would remove your egt probe and use that 1/8npt hole to plumb in an air fitting. Then add shop air and hit it with some soap.

 

[lariat 7.3]

so basically where the down pipe bolts up?

 

[neverkickn]

Yup. Make sure you clamp it on good so it doesn't blow off.

 

[lariat 7.3]

what size is it roughly

 

[neverkickn]

don't remember.

My Ex runs about the same temps as the OP's when towing, my eyes are almost always glued to the gauge. I know I have no leaks. Checked and rechecked multiple times, all good.
I think I'm just going to hit it some some water to cool it.
Now I have been wondering, could it be the gate on the 38r that's opening wrong?
