Exhaust Brake Pressures

[PLaFrombois]

Has anyone had any problems from an exhaust brake that's attached to the turbo? I'm still trying to determine the pros/cons of each manufacture and possible problems that are associated with them. I understand that when the exhaust brake is "on" it restricts air flow which causes pressure to be used in stopping the vehicle. My question is: Will there be to much pressure and heat built up to caues damage to the turbo over time? Is there a certain manufacture over another that should be looked at for ease of operation?

Trying to get as much information as possible before making my decision on an exhaust brake.

Thanks

I am consitering a brake as well, and i wanted to know about the sound. I belive these operate differently than the internal ones built into larger diesels that have that mean sound. Do the ones for our trucks make more of a hiss?

Paul, I have the BD 4" which is located away from the turbo. farther down the exhaust pipe. I'd hazard a guess that you would have to leave it on for a very long time to damage the turbo. I have had mine on for over a year now, use it everyday while driving and at every start up in the cold months for a quick warm up at idle, the turbo is doing fine.



krussell... you are correct, they don't sound like a true Jake brake on the big rigs. Inside the cab it sounds close to a Jake brake, outside the cab you hear the hiss. Very amplified with a stack, mine sounds like a 767 heavy when parked at idle with the brake on

I dont know about the others but Jacobs does not void your warrenty, and yes they do hiss at an idle, sounds like a bad flat tire. and at higher RPM its just like the big rigs , my Jacobs raises the temp at idle aprox100 degrees , this is an excellent warm up feature ,I cant tell what it does at higher RPM. I have had it since truck was new and would not do without it especially if you tow and then IMHO its a must,think of it this way we have plenty of go but need more whoe. ... ... ... ... . Kevin

I noticed all the people ASKING about brakes had autos; those of us answering have manuals. Big difference! Make sure you talk to someone at BD about required mods to your transmission before installing the brake. It can be done; it just needs to be done right.

Damage to Turbo? Highly unlikely, or Cummins would void the warranty for use, which they don't.

You will get some crud on your IAT sensor; but, if you idle with the brake on your injectors will burn hot enough to stay clean. One member reported on injectors with high idler - deposits. Second set of injectors after exhaust brake used for idling - clean. Recent training and reports from Cummins confirm this observation. Sold me!

P. S. - Also helps slow down the truck!

HC... good info and I missed the fact that they had autos . I had the same experience with a high idler stick I made when the truck was new. The injectors looked like crap after only several thousand miles. When the BD 3's came out for the 5's, the 3's were spotless. The 3's went in when the BD brake went in.

BD exhaust brake

I've had a BD exhaust brake on my 99 auto for 3 years and 3 months and have been well satisfied.

I also have their autolok to make the torque converter lock up when in de-cell. I have 119,00 and 450 hp and all is still well. Hope this helps.

BigSaint,

I was just reporting what you had previously told us on your experience on the injectors - I remembered the report was very good and factual, I just couldn't remember who posted it! But it was great info - thanks again!
