For those of you towing heavy 14,000 plus with stock 2003 HO engines and a six speed and equipped with gauges, what EGTs are you noting when pulling a load? I am trying to evaluate the need for gauges and measures for reducing EGTs when I tow my fiver. Obviously if EGTs don't go that high, I won't need to do anything. Thanks.

I have only seen 1,100 on a long hard upgrade pull with a heavy trailer.

 

Hey Casey I saw 1150 max going up an 8% grade in 6th at 55 before I downshifted. That the highest I could get. I have the AFE 7 intake and was towing 14700.

 

Hey Casey
I installed my pyro after the turbo (like the class 8 on hiway trucks do). I think it is the best place for a unmodified engine. In about 25000 towing Kilometers @ 20500lbs gross weight. I have seen the Pyro at 1000 degrees F only three times. One was pulling north from Stovepipe Wells in Death Valley and you go from -5ft. to about 6500ft above sea level in fourteen miles. The ambient temp that day was 88 degrees F.
I also hit 1000degrees in the Smokey Mtn.s from Pigeon Forge to Cherokee NC.
I installed the thermocouple in my exhaust brake between the turbo and the ex brake butterfly valve. Interestingly enough I have seen 700 Degrees F coming down a long grade.
My reasons for doing it this way are as follows
1 you do not have to remove the turbo or take precautions not to contaminate the turbo.
2 That is the way that Kenworth, Peterbuilt. Volvo, & Freightliner all do it.
The disadvantage is the price of the skinny little gasket that you have to get between the turbo and the Jacobs Ex brake the part # for the gasket is 4089324 and the price was $53.12 Canadian.
Hope this helps

Well first off, mine is pre-turbo. The debate on which location is better rages on...

Second, I have hit the 1350* range with as little as 8000lbs behind me, so I firmly believe gauges are necessary. With over 22k rolling down the road, I really have to watch the EGT's pulling the hills. There are a lot of times where I have more go pedal, but the EGT's hold me back. You learn to drive via the gauges, and not the "performance".

In my opinion, gauges are mandatory. Just my $.02, though

 

I'm post turbo and have barely touched 1000 on occasion,,usually see 850 to 900 at 24 psi boost on long hard uphills

 

Yup, I think I will need a pyro. Pushing 1000 degrees post turbo is getting up there. Thanks guys.
