High EGTs

We all know high EGTs are bad. 1250* is the magic number. These are things we hear all the time.

But what I have NEVER heard, is what happens if it gets too hot? What is it that we are afraid of hurting? The turbo? The cylinders? Heads?

Cracking/melting of the pistons.

Your pistons could look like the ones in Joe's post here at the nation Pyrometer Gauge - Ford Powerstroke Diesel Forum

The turbine fins on the exhaust side can also overheat and bend/melt.

We're worried about heat soak. Hitting 1600* isn't going to hurt anything as long as you don't keep it there too long. A drag strip pass or sled pull is fine. I was in a mud bog awhile back and my egts were threw the roof but that's to be expected. When I pulled out the egts at an idol were at 700* it took about 4-5 mins of letting it run parked to get back down to 300*

Your watching EGT's to protect the pistons. Period.

Your motor will blow to little aluminum pieces long before you will damage the exhaust side from EGT's.

Pistons is it.

I saw a diesel smoker tractor last weekend melt the exhaust fins in the turbo from a sled pull. He didn't get the head off yet so I don't know if the engine is ok, but the turbo is impressive.

Lots of water injection can keep the intake temps down enough to where that can happen, but in a normal set up its not possable.

Just search on youtube powerstroke turbo jet...

Now that you mention it I think he is running water injection. I am not sure what his exact setup is.

Joe, where did you get your water, meth injection from. Can you post the site. Also did they supply the 9 gallon tank. And do you just use water or both? I know some people say just the water is enough but I couldn't see how it would help in power. Thanks,

Chet

I prefer cooling mist...

Water Injection, Methanol Injection, Alcohol Injection Systems | Coolingmist

Run water injection to cool the fire... Run fuel to fuel the fire...

If you want more power, look elsewhere. While you gain some power with water/meth injection your much better off to run more fuel.

Thanks Joe, it is to just cool the fire while towing. My boy needs this in his 6.0 also. He pulls way bigger then me. Okay after looking what kit do you recommend? Its for towing heavy, and I'm going to have 200/80 sticks soon. Thanks
