BD Exhaust manifold kits

[HeavyAssault]

Has anyone tried the BD kit?? Seems like it may help on airflow to the turbo. For all the work that people do for a turbo swap it seems like adding a tad more $$$ change into the mix could add some decent results.

What turbo

I'd use a stock or modded stock VGT myself. I wasn't sure if anyone went down this road with a customer or for their own truck.

They don't make them for the 2016 i believe. Actually they make one for one side and not the other. The machine shop was looking then up and that's what they found... I was also told they don't make much difference.

BD just released the 2015+ kits.

While the 11-14 kits have been out, I haven't seen any reports of shops/people installing them. As anything with a motor increased airflow or the "smoothing" of airflow tends to help a motor.



I figured there had to be someone who dropped the 11-14 kit it with a build or when they swapped around turbos.



I've been quote happy with my 2015, just thinking of giving the OE turbo a mild mod/rebuilt figured with all that stuff off.....why not go a little deeper.

I bought a set for my 2011. Turbo started surging/fluttering under steady throttle up a hill with or without a trailer at 52-54 mph just like it's laid out in TSB 11-12-14. So while I'm in this far replacing to an updated '14 turbo and WW2 (make fun of me if you wish) I was going to do the studs and manifolds for reliability after hearing about them being fairly common to break and hopefully some performance (wasn't too much more expensive than stock replacements). I asked BD about what to expect and got a nondescript:
"Our manifolds improve on the reliability of the Ford manifold, while improving the radius’s from each cylinder."
It will be mid June before I get them in the truck but they look good in person. I can let you know more after install. I don't think I will be able to pinpoint specifics on performance of the manifold upgrade though since I have more changes going on at the same time.

Thank you. Sounds like the drive ability will be where you get the improvement. Maybe monitor the PIDs a tad more to see what changes. I know in the past my mods like this made the turbo much more driveable and had better spooling. Airflow makes it all go....

HeavyAssault,

Any specific PIDs you want me to compare? I'm struggling thinking of one that might tell me how much better the manifold is flowing. EGTs maybe? There is a back pressure measurement but I believe that is across the ***.
