Turbo mount brake and Aftermarket Turbo

[TBydalek]

I am looking at buying a turbo mount brake for my early 04 which I have upgraded to 04 1/2 exhaust elbow and downpipe. What I need to know is if I get a 04 1/2 direct mount pac-brake, and in the future want to upgrade turbo will either the BD super B or the B1-04 work with the 04 1/2 direct mount brake? BD is telling me their direct mount brake for the 04 1/2 will not work with the super B because a part of the casting will hit the firewall. Any help or comments would be appreciated. If anyone is running either a Super B or the B1-04 with a 04 1/2 direct mount exhaust brake please let me know.

The new Super B comes with adapter so You can use a Pacbrake turbo mount at least for a man trans dont know if auto is any diff.

I am getting the Super B and my Turbo mount Pacbrake will fit the new model that comes with adapter

I am getting the Super B and the BD Turbo Brake on an 05. Supposedly it all fits together. We'll know by next Tuesday. I'll post up some pics when I get it back.

I used the 04 1/2 Pac-Brake with my B1-04 to get a true 4" from the turbo back. All bolt together with no fabrication. Did have to bend the stock hanger on the downpipe to fit. Not bad, a little heat and a tweek and all is good.

That is strange I have talked to two different people at BD and they say the 04 1/2 brake will not work with the super B. They say the super B moves things back enough the brake will hit the firewall. Does anyone already have the 04 1/2 brake installed with a super B. bpenrod how close is your brake to the firewall. Thanks for any help.

I have the same setup as bpenrod. The pacbrake is about 1" from the firewall. The B1-04 has an exhaust housing that is about 7/8" longer than the stock turbo. It all fits in there very well.

Just get an inline brake - then it will work with any turbo.

i've never seen pics of how an inline brake is sealed to the piping on the inlet side of the brake... anyone here got pics or know how it is sealed? [60psi backpressure in a pipe 14g or 16g that isn't designed to hold very much i find slightly disturbing]

As Jeff mentioned, my brake is about 3/4" from the firewall, it looks a little closer because of the insulation there. Overall I'm very happy with the combo an dglad I took the time to find the right setup. I have no personal experience but I have heard the in line brake is a little slower to activate while it fills the exhaust. Probably only asecond or two I would imagine. Iliked the idea of the brake up in the engine area just to keep it out of harms way.

V-band clamp.

V-band clamp.

ok... that will hold... now do these kits come with a new downpipe or just a flange that gets welded to the downpipe to attach the brake?

 

[KLockliear]

Nope, you cut just about 10" out of any straight section of pipe, as close as you can get it to the turbo, and put it in. They supply the flanges that clamp or preferrably weld to the pipe. Here's a generic picture:

Keith which brand do you guys sell and how do they regulate backpressure, fixed orifice or pressure regulating?

 

[KLockliear]

Pressure regulated, with a pressure diaphragm (much like a stock Dodge wastegate). Set for 54psi. We sell the US Gear Super Duty D-celerators.

The inline brake in either a 4" or 5" is now available from Pac Brake in the new PXRB design... . I started shipping them this week... ...



The mounting flange has to be welded to the exhaust pipe... for a great seal... .



The only downside to this installation is the extra time to weld the adapter to the pipe and the 2 - 3 second delay for the pipe to fill to come up to the full 60 PSI back pressure... . but with the bigger turbo and higher flow rates you can hardle tell the difference in the time delay... . besides you need from 1 to 1 1/2 seconds for the fuel rail pressure to drop before the exhast brake comes on... .
