EGT's when Racing or Pulling - What's Bad?

I know these trucks, assuming stock internals, aren't supposed to have a sustained EGT over 1250. When drag racing or sled pulling, I've read that most exceed that limit quite often and by quite a bit. I've also been told it's okay to run higher EGT's for a brief moment, but that's pretty open ended.

It's going to take a while for the heat to actually soak into the metal parts, but how quickly does that happen? With these new injectors, I can see 1550 pretty easily, but it comes up quickly rather than just climb slowly. I have plans for a bigger turbo though, so that should help.

What is some of your all's opinions on how high of an EGT you can run and for how long, thinking mainly of racing or pulling? Any personal experiences?

Re: EGT's when Racing or Pulling - What's Bad?

Depending on how tight the track is 1775* is about all I see. (need more fuel)That only lasts a couple seconds. I think the drag guys may have longer heat cycles than pullers. Only when I'm pulling a trailor do I ever look at the pyro on the street.

Re: EGT's when Racing or Pulling - What's Bad?

Ditto what he said... I can bury the 1600 pyro for breif times when pulling hard, but as soon as ya let off its back down...

I think you just have to feel safe, some never go over 1300, others ride it to the end... Anything over 1250 is a risk, how much of a risk you want to take is up to your right foot...

Re: EGT's when Racing or Pulling - What's Bad?

I have ran mine to 1550-1600 for a few seconds and have yet to have any problems but you never know the next time I do it it might crap out but oh well that will just mean time for upgrades.

Re: EGT's when Racing or Pulling - What's Bad?

I buried the pyro straight down at my clutch foot from the top of third gear until the end of 5th gear everytime I went wide open throttle for the last two years.

That's around 30 or 40+ seconds easy. I can feel it. You can feel when the engine is actually getting heat soaked. The cab starts to get warm and you can just feel/smeel it or something. It's hard to describe, but it's there. At least in my truck. Maybe it's radiated heat off of the floor or something, but the truck definately warms up inside the cab when it's time to get out of it.

When I'm driving with the windows down full throttle it's just a game of time.

I would have to time it to know how long, but you should be able to tell just by feel. You can't just use a time, because what if you were for instance .......

Just cruising along behind.....say a porsche at around 105 or so for 30 seconds or more at around 1400 degrees......and THEN he finally nails it and you go WOT and bury the needle the rest of the way down?

What then? Is it 30-40ish seconds from the initial point crossing 1250, or from when you finally nailed it starting from 1500?

You just have to know how hard you're pushing an engine. I also have no use for my pyro except when towing. And even then it's just a reference about every 20 min or so.


FWIW, when my engine was out in Feb for the pickup tube bs, the pan was off and looking at the bottoms of the pistons for discoloration (yellowing, to browining from the burning of the engine oil from the squirters) mine showed only a light yellow tinge to it. Nothing like some of the brown to dark brown burned oil visible on the bottoms of some pistons. That leads me to believe that I have never pushed too hard......and this is someone that would set the ERROR message on the Banks SixGun when it passed 1720 degrees, lol.

When that thing was in there for the ICP testing, I would be in 3rd gear, 1300, 1500, 1600, 1650, then 4th gear, 1600, 1650, 1675, 1700, 17 and change, then 5th gear, 1700, 17 and change, ERROR, ERROR, ERROR, ERROR, ERROR over and over again perpetually with flashing red lights and sh#t for the remainder of the pull to kill a ricer or what not.

If you're on a drag strip, it's a non-issue. Unless you take it out the back, through the kittie litter and out the pine thicket wide open, you just don't have time to melt it.

But good luck with that.......

Re: EGT's when Racing or Pulling - What's Bad?

Mine are maxed out straight up and down, bending the needle. That cant be good

Edit: 2 years Charlie! That makes me feel better. I was envisioning new pistons after every season.

Re: EGT's when Racing or Pulling - What's Bad?

Charles, you have pushed it harder than I ever would have thougt about. Seems like I don't have much to worry about if I'm just running the 1/4 mile.
