How to keep exhaust temp down when I pull in the hills with 9000 lb behind me and 2300lb in the bed.
Truck is a 1993 D350 5 speed 3:54 in the rear.
Can I give it some more fuel by turning the pump up.
I have the smaller exhaust housing so it spools fast.
And 4' exhaust.
When I'm empty exhaust jumps up to 1000 if I hammer on it.
Can anyone give me some idea what I'm up against.
Out side temp today is 91.
Thanks to everyone on the 1st Gen forum.

 

as long as it doesnt stay about 1225*f for more than a few seconds you dont really have anything to worry about. my truck runs like 1600*f if i hammer on it, and thats with no load at all!

 

I have made the pull loaded but at that time I had 4:10s
I now have 3:54 that could change all that I could run in 4th yuk.

 

Whats your boost reading and EGt's when towing that load???

 

1000* pre or post turbo?

 

Our trucks are factory rated for 100% duty-cycle at 1250*F (preturbo).

That means you can run it all day long at 1250*F (preturbo) with no ill effects.

 

That's a little over 800 at the bend at full torque, about 900 at full hp.

My injectors are worn out. I find that pulling a hill in OD (automatic) and a tight Goerend converter at 1800, it'll tend to overheat. Third gear at 22-2300 rpm and it builds more boost and cools down, same hill.

 

Pre turbo temps.
I have not made the trip yet.
When it had 4;10s the truck pulled it like a Mack truck top speed was only 72 or 76 mph mashed to the floor. It did like going 55-60.
I would think if I take it easy and keep the speed at 60 it should be fine.
What will turning the psi do for all of this.
