Does anyone out there have a jake brake in there truck and if you do were did you get it. It no has do you know where it get one and is it worth it.

 

Quoted from the Jacobs faq:

FAQ4:

Do you make a product for the Ford 7.3L Powerstroke or Navistar International T444E engines?

ANSWER:

No, Jacobs does not offer an exhaust or engine brake for these engines in fact, Navistar and Ford have requested that we do not develop one for these engines.
The primary concern with putting a retarder on these engines is their use of hydraulic lifters. Most engines with hydraulic lifters have fairly low exhaust back pressure limits so the performance of an exhaust brake would not be substantial. More importantly the use of an exhaust brake on an engine with hydraulic lifters can cause engine damage. The problem is that the increased back pressure resulting from the operation of the exhaust brake will cause some degree of valve float. This valve float can cause the hydraulic lifter to re-set with the valve still open (not seated). This phenomenon is known as lifter jacking. Lifter jacking could also result if a traditional engine brake were used on these engines. The results of lifter jacking can be anything from low positive power (because the valves stay open) to engine damage caused by valve to piston contact.


What some people here do is hook up a manual switch for thr Exhaust backpressure valve (might not be the correct name...)
Since this is a factory installed component it should be fine.

 

Jacobs only manufactures for Cummins
Here is your best bet.

One more thing if your towing more than 7k there is not a noteable difference than not having one.

 

Jacob's make brakes for Caterpiller, Cummins, Detriot, International and Mack, that I know of. Of course not every engine that each of them make.

 

With these motors a exhaust brake doesn't really make a whole lot of difference unless you're at higher RPM's... once it drops back down to lower RPMs you won't noticed much

 

so really not worth trying to put one in

 

turn your ebvb valve into one

 

Not worth a Jake Brake (to get that BRRRRRRRPPPPP!! like the big trucks) but it is worth it to do an exhaust brake. Just be aware you have to have the engine RPMs up for it to do any good.

since i put my ebpv on a switch and played with it alittle, it works best in 3rd gear (E4OD) above 25mph, if in OD rpm under 1200 then not noticable.
