Well I picked up this new truck the other day. Got pointed to this forum by the guy that bought my Excursion. I saw a 4 door F350 7.3 last year and joked to the wife about finding one. Well I did find one and it's a pretty cool truck. The 02 F350 dually long bed 4 door I had was pretty sweet to.

I've read a bit, got some good info. My diesel experience is not much... a few chips here and there, a few cold air kits, some custom exhaust work and that's about it. My modded diesels in the last 10 years are mild I guess.. as compared to what I read about. Other than a ATS tranny in a Ram 3500 I owned, nothing ever major.

This 96 has been modded a bit. The previous owner pointed out to me the down pipe that was replaced and it's got a cleanable filter in it on a cut factory tube. He put the 3 pack gauges on it and gave me the Edge Programmer for it as well. The number 2 setting is more than edequate for me. The exhaust is straight through. The truck has all kinds of good solid power. Tranny shifts nice and solid. It's got only 68 K original miles w/ 410's in it.

So my question is if I am getting on it a bit and the EGT's are hitting the 1100 mark in the number 2 setting of the programmer, will towing 7 to 9000 LBS during the summer cause me to have to light foot the throttle climbing mountains while towing? I guess I'm wondering if the intercooler is a necessary mod or is there anything else that can be done to keep the temps down.

 

3 options, light foot, run less HP tune or get an Intercooler. even with an IC you may need to watch the gauge pretty close. for that matter no matter what you do you may need to watch the gauge closely.

I would hook it up early in the season and go for a test drive and see what the temps do with the trailer behind you.

 

look and see if the pyro is mounted before or after the turbo, if it's before the turbo 1100 isn't to high, the cut off is 1250 if the pyro is mounted before the trubo, if it's after the turbo i would stay below 950.
I would bet that it is mounted before the turbo cuz i cant get mine above 1250 unless i have about 8,000lbs behind it. I have the pyro in the drivers side manifold, and have a bully dog chip.

 

Welcome To The Forum And The Fine World Of Obs Strokes!!!

 

My Excursion 7.3 towed about the same. Somewhere around 8000 lbs w/ my Jeep and the trailer combined. The X never got to 1000 on the Pyro w/ the Gold Off Road Superchip but this one gets up to 1000 pretty quick if I hammer it through over drive. This truck feels much stronger than the X did... I guess it's the Egge programmer in combo w/ the 410's. I guess I just need to hook it up and tow of which I have not done because the hitch is a class V Titan. That thing has a 2.5" ID tube on it so I need to get some new towing stuff.

 

you never said if your pyro is mounted before or after the turbo?

 

The exhaust manifold has actually been tapped and that's where the sensor is located.

 

your not comparing apples to apples here.......


your x
intercooled
larger exhaust

your obs stroke
smashed dp and
not intercooled...

do a few mods:

intake
exhaust including downpipe
intercooler
then report back.

 

I don't think you read my complete question. The intake is done, the exhaust is done, the down pipe is done. The questions was just looking for a suggestion on the EGT's. Maybe someeone w/ a like truck w/ like mods that tows to see if the IC will be necessary or like you said placement of the sensor effecting the reading. Mine is tapped into the exhaust manifold. I can hammer it and it gets to 1100 really quick. Sommertime towing is when I am worried...

 

With it mounted in the manifold you have nothing to worry about untill you get past 1250. I dont think you will need an IC, i was pulling 22,000lb GCWR the other day and really had to drive it hard to get it past 1250 in the middle setting of my chip.

 

Well that's good news... I guess I really just need to hook it up and tow w/ it.
