This is a simple question. What should my gauges be reading? I have egt,boost and trans. Like when idling, towing and around town cruising. Or better yet what is too much for each one? Having gauges is great but if you don't know what is too much or little then what the purpose of having them.

 

nobody?????

 

If you complete your signature to tells us what you have done to your truck, we can answer your questions much better!!!

I am running a 2002 24 valve HO (means 6-speed manual tranny). I am stock and my max boast is 19 psi. For EGT, you need to tell us where you mounted the sensor. It will be either pre or post turbo. The readings will be much different. Most will say for EGTs is a max temp you want your rig to get too. Too much heat can cause bad things for the engine and/or turbo like pistons melting.

Also, is your truck a 98 or a 98.5?? It makes a difference on how many valves you have, cause if your are a 24 valve, you really need to install a fuel pressure gauge.

I was getting ready to bust your bubble, but since your from waldorf,md (so am I) i'll let you pass. My truck is stock with a modified fuel plate(100). The egt sensor is mounted after the turbo. Also its a 12v like my signature says.....

Does it matter if the sensor is after the turbo? Should it be somewhere else for a better reading.

 

since your sensor is after the turbo the temps are cooled a bit so you are not getting the true temps rite ate your engine,some say there is a 200-300 degree diference,it should be mounted on your exhaust manifold.as for temps anything over 1300 is hot and prolonged in that range could spell trouble,but remeber to add 200-300 to that for yours so keep yours under 1100.as for your tranny someone will chime in with that,{i have a stick}

 

I missed the under-valved part. It is funny that you could be a neighbor. My truck is a white quad-cab with Texas plates. 2 days ago, I almost dropped my tank cause I thought I had a clog in it. Turned out to be a combination of a failed fuel gauge separator and a brand new lift pump that failed. That would have been lots of fun since I still has ice and snow on my drive way.

Back to the original answer... I am not sure what your tranny should be reading. I hope somebody who is running an automatic that is monitoring the temperature will chime in. I recall some past postings talking about automatic transmission temperature and I think the group concussion was under 250 or so.

Best of luck,

I live in carrington.

 

My Tranny Temp has never been over 200 degrees but I haven't towed with
it.

 

P/S Your egt's should be kept under 1300 degrees.

 

Rule of thumb is 1250 degrees sustained when the pyro is pre-turbo. Variance between pre and post turbo can be as much as 500 degrees when into it, and next to nothing while idling. When going 120 km/h (75 mph), my EGTs will be anywhere from 600-800, depending on terrain and head/tailwinds. Boost is generally 5-10 psi at that speed, but varies up and down due to terrain and winds. Average is 700 degrees and 7 psi.

 

an auto tranny shouldn't get any hotter than engine temps.... but that depends on where you have the probe.... if it is in the "hot" line going out of the tranny to the cooler then it'll read hotter than engine temps.... if it is in the tranny pan then it should read engine temp or cooler.... i mounted an auxillary cooler and fan under my cab and i see ~150* while towing a car on the interstate....
