As most in this group probably know by now, in early March I intend to get rid of my stock(well stock for an 03 truck) turbo and go with Matt's 62 mm fixed turbo as such will lose the ability of the VGT as a "Jake Brake" and I was wondering do they offer a true Jake Brake for light duty trucks or is the exhaust brake going to be the only option at this time? The reason why I ask is that something about an exhaust brake just doesn't seem right to me, now I'm not an engineer so I don't have anything to back that up that's concrete just from what my understanding of an exhaust brake(which from a technical standpoint is limited) is. Any and all help is appreciated. Thanks.

 

Never saw any info for a jacobs brake for any small diesels.If you saw how they work there is not room under the ford valve cover. the jake assembly sits on top of the rocker assembly and is manualy ajusted. I don't like an exhaust brake for one reason too much back pressure.Now the one on a Cat works good but leakage problems is in flywheel housing.

 

That's what I was figuring that they were doing and to me that just didn't sit right. I figured that the true original Jake Brake's would be too big for my little truck, but in this day and age of shrinking everything, I thought maybe someone was working a more compact version of it that would work with our trucks.

 

i used an exhaust brake on a 97 f-250 psd and it worked good for me. i made two trips to alaska using the exhast brake. i have been told that it was hard on the transmission. i made the exhaust brake with about 12' of wire and a starter switch.

 

Just a thought, I'm no expert on this in any way, but if there was a jake brake setup for the 6.0 you would probably have to change everything on the top end. Cost would be rediculous and uneconomical.

 

I dont know about a jake style brake, but you can get a exhaust PAC brake or one similar from BD diesel performance.

 

To some people, I have reached that point and beyond.

 

I have a BD exhaust brake on my 05. It works well holding the truck back. It will maintain your speed or slow you down depending on load, grade and rpm's. The brake is set to have a max of 45lbs of back pressure. The top end should be good enough to about 60lbs +or- before valve float can happen. There was a post about this a year or two ago. As I understand it the injectors do not fire or fire very small amounts of fuel when I am off the throttle so there is no confusion with back pressure and cylinder pressure. The brake will only work at idle and talks to the vgt and egr through the ebp sensor. I have had my brake installed for a year now and the problems I have had were, 1) The hpop blew last sept. The dealer covered it under warranty with the brake installed. 2) I had problems with the BD brake module and BD covered it under warranty. The truck runs very strong so I see no problems with the motor using an exhaust brake. I have a 6 speed so I am not sure how well it will work with an auto. I do believe you need to add an auto lock so to talk to the tranny and lock/unlock the torque converter. I was told by the installer that they do not work as well on auto trans. As far as a true jake brake I do believe that the motor needs to be made to have one. I believe they are a bit complex.

If you have done any towing with your auto trans 6.0 in tow mode the turbo acts like an exhaust brake in lower gears at least my 05 will and it will slow you down

 

Won't have that luxury with the aftermarket turbo. As of now I have it setup for the VGT to act as a "jake brake" but I lose that with the new one.

 

Right now I have an EGR bypass and I won't have the VGT turbo in March. I'm going with the fixed turbo. If it has issues with autos outside of my other concerns that I might want to definately stay away from exhaust brakes. I might just have to do this the old fashioned way and do without.
