Default Lowering EGT's

O.K....her's the question, I have asked a number of people and so far there is no common answer...Since I upgraded to the "Hot Juice" my EGT's climb alot faster, I have heard everything from a bigger intercooler too a bigger turbo...injectors you name it. Any ideas on how I could lower them...Ive read that a boost fooler will lower them around 275 degrees but I dont want to invest in something that isnt going to work.
Any help would be greatly appreciated.

A bigger turbo would get my vote, as to the boost fooler, doesn't the edge already boost fool? How much boost do you see?

Have you considered water/meth injection?

Ive hit 52 lbs of boost, so I dont want to go with a boost fooler unless Iam sure it would work, as for the injection...from what Ive heard it is the same as running nitrous on a car not built for it and cut down the life of the motor.
Iam at a loss here.

I just installed this Mega Mouth elbow off the back of the turbo and it has made a huge difference in EGT's. It stays around 100 degrees cooler at full boost on my truck, but the huge difference is how fast it cools down when I get out of it. I can go from 1000 to 300 within seconds. My truck has never been over the 1000 degree mark and with this thing installed I can't hit a 1000 even with the Drag Comp turned all the way up.

Im not an expert but I really dont think water/meth will hurt the engine. Nitrous...maybe, but I kind of doubt that as well. These are medium duty engines and the internals are pretty stout.

Well the thing is with water/meth, if you run to much methanol...your headgasket really stops liking you. You could run the water injection solely for the egt lowering. But that's more of a bandaid. From the looks of your truck you're not gonna stop bombing anytime soon. I'd say get a bigger turbo.

W/M isnt too bad. You can run straight water or even windshield wiper fluid is pretty cheap. It is nice B/C you can add more meth for the track or run wiper fluid or straight water just to cool. A good mix and just a small amount will help alot. You dont have to have two huge nozzles with it cranked up, I just run 1.

Water or turbo... I think 52lbs of boost on a stock turbo has you living on borrowed time already. Maybe you can kill two birds with one stone.
