i was hauling my boat up to the lake with all that weight behind me made my etgs rise going up hill . any way to lower the etgs trying not to melt my turbo i had cruse control on it and it spiked up to 1200 degrees nothing terrible but im just trying to keep em low

 

bigger exaust housing and dont use cruise by using it if youre goin through any hills it accelerates goin up and decelerates goin down no good for your econ or temps accelerate goin down one before u go up the next so you can ease on the throttle till you peak that will keep egts down and econ up

 

upgraded my ehaust to a 5inch strait piped and yeah i went a new way to lake my mistake leaveing it on. my question allso is how do those guys who are doing truck pulls not melting their engine block or blowing a turbo? now ive seen a ton of gmcs and Chevy blow a turbo but thats another matter

 

well a 4 inch is more than what you could ever need in a 7.3 unless ur makin 8-1200 hp, im talkin about the turbine housing not the dp you have i believe it was a .82 factory turbine housing or snail if you go with a 1.0 like i have you keep backpressure down and temps down as far as burnin up the turbo as long as you keep oil to it you can run at 18-2000 degrees for hours and be ok the bigger problem is melting the inside of your engine down like our aluminum pistons if you run your truck had heavy load or what have it just make sure you idle a few min before you shut down the motor too cool down the turbo and engine and youll be a ok...

 

Bigger housing or run some water/methanol.

 

international says you can run at 1250* all day and not hurt anything.

 

cool thanks guys and i went with a 5 inch because it was only a 150 more than a 4" from where i bought it from.

 

Down shift your truck, let the RPM's come up and you will be fine.

You can pull all day at 1250* and not hurt a thing, and just as a reminder, your not watching EGT's to protect the turbo, your watching them to protect the pistons inside the motor.

 

Maybe put 4 EGR Coolers form a 6.0 on it with duct tape? I thought those were supposed to help? :P

But I am sure upgrading your intercooler and piping will help some, I've heard people get 100* lower after putting a bigger intercooler on and slightly bigger/aluminum piping.

 

You can drop some good temps with an expensive IC for sure, however you do not change the pipe size...

However an intercooler is $1000-$1800...
