EGT's out of control

[EMD_DRIVER]

I pulled my fifth wheel about 25 miles this evening and couldn't get above 55, unless I was on flat and level road. My EGT's would easily climb to 1250* and I would have to back off the throttle.

I did delete the cat, but didn't remove the stock muffler. I also haven't replaced the factory DP yet.


The fifth wheel weighs in around 10,000lbs. Would changing the DP and deleting the muffler help enough, or is there anything else I can try?

It would be a good start. Gary don't be afraid to use a lower gear and lets the RPM's work for you. If mine drops down below 2,000 rpms the EGT's really climb, and it's down on power. Mine like to run @ 2100-2500. So with having 3.55 gears, I run either OD @ 72 mph or drive @ 55 mph. It's not really happy any where else. The PSD really use the turbo to make good power.

yeah mine takes off at 2000 and really pulls hardest 2500-2900 rpm.

if i were you i'd get the NAPA 6637 intake and a good free-flowing exhaust on there.

Mine's the same way... I already have the 6637 intake.. Guess it's time for a new exhaust.. The CAT delete helped, but not enough for what I'm pulling.

I like the turbo back 4" HERE

Soon as I come up with the $300... I may get it!

Is there any kind of chip, that would turn the fuel down a bit?

 

[FordGuy100]

No there are no chips that do that. I would get a new downpipe and at least tale off the muffler. That will help a good amount.

What about water injection. Set it up only when towing the 5er

ya could have one made, but then top end would be lacking,
give it more air and a dp will help,

my old sd did way better than that 96 ever did
my 96 cc did good with the 26 footer

ya could always do what 90% of the guys that own them obs trucks do , hook up and go and not have a pyro

I can't do that.... I made sure I had a pyro BEFORE it ever towed anything!

The DP is definitely on my to do list now!

Where can I find water injection info, for this truck?

 

[gatorman21218]

Dunno. i dont even know if its possible for a stroker just tossing out an idea for you.

 

[EMD_DRIVER]

Thanks for the idea.... I am looking for options!

 

[EMD_DRIVER]

I went searching for water injection systems and was astounded by the prices!

I did happen across one page, that has my curiosity up though... CLICKY

I don't see how this could over hydrate the engine, and may try to fab one up... We'll see! Since I don't usually tow the 5er in winter, the water wouldn't even need to be used...

Toss the muffler. It's a good start. Wind it up a little, a different gear will help sometimes.

Chips are multi position. You might find something you like. Worth looking into.
