Run Exhaust Brake To Save Turbo?
 

Good afternoon!

I was talking to a guy earlier about the adjustments to the turbo made possible by Smarty tuners. His exact statement was:

"the turbo on all 6.7's are a VGT (variable geometery turbo). there is a slide inside that moves and adjusts the vanes inside. this also accounts for your exhaust brake. always 100% of the time run with the exhaust brake ON. this helps reduce the carbon/soot buildup on the slide and keeps it moving in full range."

So my question is that is it ok to run with the exhaust brake on constantly? We run a few transport trucks and our diesel mechanic always turns the exhaust brake off on them because he said the drivers play with them too much and they are not necessary to have where we live. He also says that they can be harmful to the engine and it's they make fuel mileage worse.

What do ya'll think?:humm:

Run with it on all the time. It helps clean the turbo and saves on brake pads. Nothing but pros for running it all the time.

i ran mine all the time when i had my vgt never caused me no probs also helps to run it all the time for the guys still running dpf helps keep it clean also

i run mine too.:tu:

bought my truck with 15 miles on it,i ts always been on and stays on,im at 160,500 right know runs great 17-18.9 mpg(at 70mph)no check engine light,no major dpf problems.(every know and then if i dont let it regen it turns light on and low fuel pressure code,but then after it regens light goes out and its good.:hellox:)

Any way to program it so this is on automatically and you push the button to shut it off, forget sometimes for the first few mins, would be better if it was on automatically.

Yes there is a way you can wire it to be ON all the time. Just do some searches on google should be on the Cummins forum.

Thanks I'll check!

I seem like I'm doing an info-mercial for this website, but I'm not affiliated at all. There's a step by step "how-to" on this at www.carbonitecummins.com:tu:

I ran mine for a year but one day I was pulling my toy hauler on the freeway (I 15) and it started cutting out so I turned off the electric brake and no more problems the since.

I've been turning mine on every time I start the truck from day one. 57K and I still have over 40% of the front pads left and over 50% on the rears... I'll buy the parts and plan do to the brakes around 75 to 80K.

I'm 100% certain, that it's fun to use, makes cool noise when it comes on, saves brake pad life considerably.. and knock on wood I haven't had any lights, issues with dpf's, turbo problems, nothing. I do run the thing about 25 miles each way to work and it's on the highway, with a good sized hill I blast up @ 75 every day so that may, make a difference I don't know... but so far so good.

Sounds good! maybe I'll try it again.

I ran with mine on for the first 50k every time I was in the truck, then I put the S475 on.

the first thing i do to my truck when i start it is reach and push the exhaust brake on. :tu:

Same here than the High Idol kicks on and it sounds like a jet ready to take off.. :rocking:

yeah it does jet a little when cold. :hellox:

it sounds pretty sweet when i first heard it i was like whats it doing ha ha

Yeah my neighbors officially hate me. If their not awake at 0545, they are when I start the truck to warm up:choochoo:

hey , speakin of exhaust brake , I had my turbo replaced the other day at a dodge dealer , now my exhaust brake don't work , are they supposed to program it with a new turbo to the computer , or what dud they screw up ?
