Stock Towing EGT's

[MaxedOut]

Anyone tow "stock" (no juice) with gauges? I'm curious to see what the max temps would be towing a substantial weight & pulling some good long mountian grades.

I pull 17000 lbs stock wiyh gauges.
Never exceeds 1000F

I have hit 1300 degrees stock already. All depends on the location of the thermocoupler and the type of gauge. I have Isspro and its mounted in the passenger exhaust manifold. I was over max on weight and pullin' a good mountain. Everyone on the board will give you a different answer.

I agree with Maverick and have the same set up. Have not seen 1300 but have seen 1250 pulling a big grade in Montana. 17,000 combined wt.

I have seen 1200 degrees stock pulling 9,000 lbs through KY, TN, area. Isspro EGT, drilled into exhaust manifold like the others.

I was going to post a similar question this AM.

I am pulling 9,000 LBS in 100 - 105 degree weather climbing 6% grades. All I can hold is 50 MPH and she runs 1,200 degrees. It has more power left, as soon as I step on it the number go flying to the top.

Thanks for the replys.
Christo - I'm assuming that your EGT is after the turbo?
Maverick - I've mounted the thermocoupler in the same spot. I have the BD gauges.
Basically, I was looking for a base line "safe EGT number". I'll be towing through the mountians on the week-end & will see if my numbers jive.
Could I assume that GM would design the D-Max in stock form to be able to pull safely in real world worst case scenerios - steep mountian grades with high outside temps and a 10,000 + pound trailer behind it . If the highest number reached in stock form is say 1300, could I use this number as the point where I would have to let off when towing with the juice? I added the EZ Amp box & gauges last week and can't wait to try it but I should probably tow stock first to establish my own "safe" benchmark. Am I being over cautious?

Doesn't sound like the "Juice" running on #2 adds much heat if any. Later! Lone Eagle

[christo]

Yes my Isspro EGT is post turbo.
Sorry, I should have mentioned that.

[Maverick]

I've ran up to 1500 degrees with the reg. juice on #2. I would be very careful. Level 1 seemed very safe as far as EGT temps go on any hill I pulled. Level 2 can get hot.

You are smart to set a base line. Thats what I did also. My limit was 1350. I back out of the throttle if it went above that.

I have a new 03 with 1200 miles, Autometer gauges, EGT mounted pre-turbo, Banks exhaust and no juice at present. I just returned from a weekend trip to Oregon coast ... no real long pulls but lots of short, steep grades. Outside temp was only about 75 degrees ...never exceeded 1000 degrees. I weighed on the trip going ... about 17,500 gross. Tranny got close to 200 on a few occasions but ran about 180 for most of the trip and EGT 750-800 down the freeway.

I have seen much of the same stock temps as everyone else but want to add that with the VanAaken Smart Box E my temps went down to the 850-1050 range towing in level 2. Level 2 adds 70 HP and when pulling a long hill in OD the EGT will cimb up to 1300 just before the trans. downshifts to 4th gear. Then the temp. goes down to 1050 and stays there for the rest of the climb while maintaining speed.

:confused:
I just did the install for a SPA gauge. Looks good but. Truck is stock. No load. Left the house to check it out and getting in it just a bit but not exceeding 60 mpg got the temp up to 1264. The hill was moderate. Got the boost up to around 20.5. I was not expecting that high of egt with no load. I'm wondering what I'm going to get with my 12500lb trailer attached. Do I have a bad thermocouple?
What are you guys getting with no load moderate climb?
At 55 can see 450-850 degrees. Whats with that?

20.5 inches is more than a little bit. Later! Lone Eagle :D

[Inspector]

Just got back from first tow. We didn't go far and the terain was moderate. Lone Eagle will know hwy 84 to Echo and over to Coalville. On the way up got the highest EGT at 1366 and 21 lbs. I was towing my 36ft King of the Road. The more I think about it I thinkd the thermocouple may be out of Cal.. At idle will only cool down to about 345. I would think that below 300 should be expected. Coming back down to Layton EGTs were commonly in the 850 to 1150 range pulling easy. somthing just isn't right with the readings. I don't think that it is the truck. Any comments?
I am using a SPA gauge.

[Lone Eagle]

Inspector, How much does that 36' weigh? Mine never cools down to 300 after the engine is warm. I see a lot of 800 to 900 on the level. As you know we don't have much level ground in Utah even on I-15. Watch your boost gauge when the temp goes up. Sometimes the raod looks flat but isn't. Later! Lone Eagle :D

[Inspector]

Lone Eagle:
The trailer weights about 12500 water and propane. Add a few options and I would guess near to 13200. Roadloaded to about 14000 plus truck. I would say pretty close to gross. This weekend not even close. Half tank of fuel and 1/3 tank of water, bottle and a half of propane.
I just thought that the EGTs were little high.

Inspector,

It sounds a little like you are estimating the weight. If you have not weighed your whole set up when fully loaded and ready for a trip, I would strongly recommend it. I think you will be shocked. Trailer manufacturers have a way of estimating weight that I wish I could use for my personal weight.

I have been towing this same rig with a 93 one ton duelly for that past 5 years. The EGTs would rarely get to 1150 12. Most of the time in the 800s while towing. The old 93 did it well. Could be that GM has turned the 03s down as stated in another post. If it weren't for the high EGTs I would be happy.
