how high are EGT's do you think?

At my job we use Cat 3121 (I think thats the number) engines for pumping purposes (frac pumps). Sometimes after running them hard the turbine housings will glow orange. I know that can't be good.. I was told that it is normal and happens all the time... ummm...

Wow....That is hot.

I saw this happen on an Audi with a gas engine after a hard run.

Another co worker mentioned the housing will be come translucent and you can see the turbine blades spinning inside.

In his imagination, maybe... even with a glass turbine housing, the wheel will be spinning at 100,000RPM+ and would look like a solid object. Think about your engine's radiator fan chuckin' along at idle speed.

There's the impeller speed. Then there's the fact that steel can't be heated enough to be clear. Unless you're Superman but then you could also see through cold steel, too.

OK, maybe he was high... that's what he told me though...

Happens all the time if you run them hard. I have a 1.8T and can make it really glow if I work it hard.

The engine your probably thinking of is a 3512. It is a 3500 series Cat 12 cylinders.

I have seen a dmax after market turbo that could be seen from the front wheel well glow bright orange during a sled pull. I don't know what temps are bad for those larger diesel plants but I would guess it's around 2000*

I once got the exhaust manifold on my old dodge slant 6 so hot it was glowing and you could actually see the walls of the manifold that were perpendicular to what you were looking at through the side you were looking at, hard to explain, but in short it actually did made the iron translucent.

LOL, used to get not only the exhaust manifold, but the muffler red hot on the old Allis WD-45 pulling 3 bottoms.

A glowing Turbo just means she is working.

The_Head

Yeah, that's it. They are huge.

SpitterGuy

I get the turbo on my SRT-4 to glow all the time. Your ok as long as you're getting oil to it.

Like this?

I'm sure some of you have seen this, I think I originally saw it here.

That's really cool!!! I wonder if mine does that when I'm pulling my camper long distances.
