I have completed many mods (see below). What should my EGT and BOOST PSI be running at 70 mph and pulling 8000 pounds at the same speed?

 

[edzzed]

i dunno the answer but if you have a heath tm your boost should at no time exceed 10-12lbs at most. mine with camper and boat if i recall was about 5lbs but not totally sure. Ed

Sorry, can't say.

Only you can tell that by looking at the gauges.

If it were possible to tell that stuff we would not bother with gauges.

I do have a heath turbo master controller. 10-12 is it. What can happen if I exceed this???

 

[DavidPhillips]

What is your EGT and boost pulling the trailer at 70?

 

[gaddington]

I mean, if I hit 20 psi, is it going to blow. I guess I mean, what is safe??

 

[gaddington]

15-18psi

 

[gaddington]

1200 degrees. Is this too high??

 

[DavidPhillips]

Stock on mine is 12 psi max, never stayed there more than a second.
Cruising at highway about 4 psi.
Should be higher with a heavy load.

You should be cautious with going above 12 for any period of time.

EGT preturbo 1000F is a fair limit.

 

[DavidPhillips]

You need an IC on that truck.

 

[gaddington]

I appreciate it. I will turn the boost down. I love this truck. I surely do not want to blow this truck up. Is 1200 degrees to high also!!

BOOM, but since i'm not totally sure perhaps you could remove the hood, setup a video camera and post the results back here. lol

 

[gaddington]

What is IC. ALso, I will turn down the boost and is 1200 degrees to high. I love this truck and dont want to blow it up.

 

[DavidPhillips]

What is the coolant temperature while your towing like that?

 

[gaddington]

High! 220

 

[DavidPhillips]

IC is a charge air cooler also known as an intercooler.

For towing heavy loads a long distance an air to air intercooler is going to bring down the coolant temp, intake air temp, and exhaust gas temp to a safe level.

 

[gaddington]

Thanks DavePhillips!!

 

[DavidPhillips]

No problem!

 

[THEFERMANATOR]

High! 220

Sounds like you need to do the 97+ cooling mods. I think your causing more damage by exceeding 210 coolant temps than exceeding the 1150 pre-turbo EGT rule.

 

[DavidPhillips]

Yep,

I just put a 130 water pump on my 95 and have the dual thermostat crossover to put on.
