Hi All,
Well I just finished installing the "Big Three" gauges - Boost, EGT, and Tranny Temp. Now I would like to know what the maximum readings I should be getting (I want to mark the upper limits so I know when I am getting close).
I should mention I do some towing of a fifth wheel. I don't race or off-road the vehicle. It's a daily driver and I just want to keep an eye on things and hopefully prevent a problem from occuring.

So what should I be looking at as far as upper limit readings?

 

i have no idea as im new to the diesel stuff, but this is a grate topic for us new people !

 

If the truck is stock, the only one you should really have to watch is the tranny temp gauge. But for the pyro I wouldnt run over 1250 for more than a few minutes. 1200 all day long is fine too. The boost gauge will probably never go over 22 or 23 at the very most, and this is just fine, since it is wastegated (assuming you dont have a chip/tuner) you will never have to worry about the boost. Im not an auto tranny type of guy, but I think that 220 is about the upper end limit for that, and even that may be a bit hot. Hopefully someone will post up a definite ATF number.

 

you will see 27 probably on boost and it isnt waistegated it it is the truck your name is of. Tranny temps not supposed to get over 225(this is where people say its too late so id let her cool if 210 is near) Pyro as stated above dont go over 1250 for sustained runs quick trips and let offs shouldnt be a problem but 1200's all day long. Pulling you will get higher boost readings. I hit almost 40 on my autometer pulling my 40' toyhauler up some 7% grade 7 miles long hills. Mine is stock as I have no tuner but do have cat-back exhaust.

 

I've seen 25 psi stock, 28 psi tuned. Hottest I've seen the tranny is 195. Most transmission damage happens over 200*. My 2004 hit 210* before and that was unloaded in the AZ summer. I've seen EGTs as high as 1200 in stock form under full load.

 

Ok so let's see if I have this...

My F350 should maintain a 25psi or less boost, a maximum EGT of 1200 and the tranny shouldn't get more than 200

that about right?
Moose is stock stock as far as performance goes, with only cosmetic "dressing up" and these gauges. I did drop down to a 17" whel but the overall tire diameter is the same as the stock Conty's

I will be adding some suspension upgrades (Ride-Rite airbags) this summer and may do the Zoodad Modification to help Moose to breathe easier. But as I said this is a daily driver so I value reliability above all.

Boost is boost, if you see 30 its because the truck needs it. You only have a problem if it is blowing the tubes off the engine. Watch your EGTs, if it seems too hot, backoff. Also, it is gonna be difficult keeping the tranny cooler than 200 in the summer towing. Just let it idle in park and cool down if you see it heading any higher.

 

My normal tranny temp is about 160 and I haven't seen it ever go higher than that. I don't tow very often but even with some load on it I haven't had it go any higher. This was in northern Idaho during elk season so it wasn't that warm out anyway. I am tuned and have only seen a max of 31 psi for boost but that is rare normally the max I see is 28 or so. To beat that dead horse 1250 is the the max I would go for EGT's.
