EGT cooling/regulating...???

I've seen hundreds of articles on the importance of monitoring EGTs with any smoker while towing, but I haven't been able to find anything definitive about how to (if possible) regulate these temps via aftermarket or DIY means.

I did try to search the board for this info, but 2.5 million posts is alot of sifting...

Any advice?

I've heard of rigs with large water/methanol tanks installed in the beds for this purpose, but the mechanics and process are somewhat vague...what the hell are they doing with that fluid? And how does it help regulate exhaust temps?

I am installing a new pyro tomorrow, but knowing my temps and doing something about them are two separate issues...

water/meth.. or just water even, aftermarket turbo will sometimes help, aftermarket intercooler ..

the water meth is sprayed in a fine mist into the intake to cool EGTs but also provides some power increase (meth is a fuel) but you could run straight water to cool EGTs

Into the intake? through the combustion chamber?

depending on the setup they may have multiple injection points
i would suggest searching thread here on specific questions or going to Snow Performance or AEM and also read what they say about their kits.. i dont currently have one, but have been considering it, but just running straight water

Took the Grunt down the turnpike for about 40 miles, round trip at a constant speed of 77 MPH to see what the EGTs would push with the new pyro installed (GLOWSHIFT GS-T708)...

Got an average of ~950F for the trip...supposedly within tolerances...any input?

Fuel makes power and heat. Improved air flow through the engine is a great way to reduce EGTs. Upgrade the exhaust, bigger turbo,but DON'T ditch the factory air cleaner unless you are making more that 500 HP. You won't find a better breather that cleans the air better. A diesel is not like a gasser and if your turbo can make the boost, it doesn't mind sucking past the factory air cleaner to do it. A cold air intake is more likely to ruin your turbo from dirt ingestion than increase your performance.

Are you saying my #s warrant these mods, or are you just suggesting them for preventative maintenance?

No, just FYI. I think you numbers are fine. There are better experts than me on the subject. From what I understand the main reason to watch your EGTs is so you don't cook expensive parts like the turbo, valves, pistions. On a 6.0 cracked heads between the valves is a very real danger. On the flip side long idle times cause wet stacking from very cool combustion temps and can lead to a build up on your valves. When they hang open they get smashed. In that case you will consider yourself lucky that 6.0 have such thin and inexpensive push tubes. The Hi-idle mod is a must if you need to idle your truck much at all.

Gotchya...generally the only time my rig gets the idle is to cool down...got that tip from some other full-timers (most tug with 'strokes), and as far as I know, it's served me well...I've pulled my turbo apart a coupla times and found it to be in very good shape...xD

Thanks for the info, though...I value EVERY SINGLE OPINION!...
