N54/N55 Single Turbo Twin Scroll Manifold ShaudFAB
 
Hello all,
Been working on some manifolds for the N54 and N55 motors. So far its been great.

Nice to see more and more options! Price point? Also o2 location?

shaudfab 09-02-2014 11:47 PM

02 sensors are being placed right under the turbo flange in the divided runners so they will not be mixed. Pricing will be around $2k mark for top mount.

Looks clean. What material and tube/pipe thickness are you using?

Thanks for the info. Thinking of going single in the next year or so and can't decide if I want to DIY or purchase an OTS solution.

Couple follow-ups related to longevity; Are you backpurging/inerting the weld environment? 304 or 304L?

304L SCH 40
I always back purge every manifold I make, can't have that sugar. :)

Man after my own heart--thanks for the info!

Good ****! So happy to see more and more options for going single. Are you saying that just the manifold will be $2K?

Well I plan on creating a kit as well but for now sell the top and bottom mount manifolds. Bottom mount price is going to be around 1500 top around 1900. This isn't cheap material I am using the best stuff here no short cuts. FFTEC are the only ones who are selling manifolds only for DIY guys. Those are priced over $3k. There aren't any manifolds for N55 guys so I am taking a shot at it with the bottom mount, I can provide the hardware but I am not a tuner.

looks very clean and tight! i have question more for my knowledge. i plan to make a top and bottom mount manifold by the end of next year and am gathering info where i can find it. when looking at the manifolds that are out there i always see the runners extend around and meet at the collector. is there a draw back of say connecting each to the next? not sure if im saying that right. say you start with one cylinder. that comes out and turns a 90 to go straight in front of the next cylinder which you, maybe, could be able to connect to with another 90, just have to put a hole in the back/bend to connect, oriented in the same direction. then have that attach to the third cyl through the bend part of the 90? then route to wherever, say down or up. i really hope i'm making sense. i'm going for the twin upgrade so thats why i'm using 3. i would draw what i mean but i should be wearing a helmet 24/7 if that would be determined by artistic talent. in my head, that has no idea about flow and what not, its kind of like the one HPF just released not to long ago, but 3 cyl and tubing instead of a machined block. Thanks for any info.

Hello,

Basically you want to make sure each runner flows smooth like water. Imagine each runner flowing water you want it be free flowing with no interruption all the way to the turbo. By placing the collectors closer to the turbo you are allowing the manifold to flow better without gases interrupting each other.

jdm5596 09-07-2014 02:29 PM

Hmmm... when could I buy one??? What wg flange are you putting on? And where?

shaudfab 09-07-2014 03:28 PM

PM sent.

shaudfab 09-07-2014 03:33 PM

Also putting a bottom and top mount kit together, looking for beta testers 135/335.

Michael1972 09-07-2014 08:00 PM

Pm'ed you about testing.

Vertigo 09-08-2014 05:19 AM

PM sent. Car is in the garage with stock turbos off right now. Stage 2 head is being installed. Ready to test fitment!

_Calle_ 09-09-2014 03:26 AM

great work, looks very nice and clean.

but the flange looks a little bit to thin for me.

Twin scroll is the best future. Waiting to see a BW EFR on the N54/N55, but they need more space as Precision.

Thank you.

Flanges are not thin. Turbo flange is 1/2" thick, head flange is pretty thick as well same size vargas, RB, fftec and VM and others use.

scotte30m3 09-09-2014 04:59 PM

I'd love to see someone make an undivided t4 turbo manifold that could be used with a quick spool valve. Those things completely change the spool characteristics of a big singles... I had one on my 2JZGTE single swap and the QSV gave it a nice flat TQ curve.

OK, than it looks thin only of the pic. :)

Motoxracer1551 09-13-2014 03:55 PM

Any updates on this? Pics installed?

I would like to see s pic of this installed on the motor in the car but with no turbo. Im just curious where the turbo flange ends up in the engine bay.

Looks really good though. This is probably the best low cost option for single turbo setups available right now!

shaudfab 09-13-2014 11:05 PM

Pm me i can send you some info.

what you are describing is a log style manifold and it should work fine, be cheap to produce, and offer great spool. they work fine on other platforms.
