Also as far as the feed goes....ee tan it that way due to the fact its divided entry. Snake another pipe shorter then the length we got it and show me its not gonna hit the turbo or heat up the compressor housing and clear the ground as we did.

And also installin the feed pipe is as simple as undoing four bolts that hold the trans up and slip the manifold on. Not hard at all. Install of the lit with the headers is right at 7hours.

And also I'm sure that it won't have to be trimmed out due to the longer primary of a pipe. Ue to the fact the the forced inducted air from the turbo feeds all six cylinders from the turbo and not three. Ur not gonna have a delay from the intake side of the motor just cause one primary is longer. It feeds the same tirbo with one discharge like all single turbos. Which means this. Exhaust gas....one turbo....one throttle body......and six cylinders. All the exhaust gas reaches the merge point of the turbo.

in physics land its a bit more complicated than that my friend, dont be to worried about trying to answer these peoples questions about air flow and such because the answers are far above most of their heads anyways. Let the dyno do the talking, and the engineers do the thinking :-D

since you know so much how physics than you should know that getting the two halfs a close to equal length as possible would be best

FYI, I have never used 1.5inch pipes when making a turbo feedpipe for a 3.5 less it was for a wg
Again not bashing just trying to understand why somethings were done. The craftmanship is what it is, can't wait to see 2gen version of this setup

Criticism and not praise on the business level.... We are all about making our kits looking one off on every stand point. Reason for utilizing schedule 10 pipe and bends with back purging insures 100 percent penetration and also is a lot dnser material Then 16 gauge stainless pre bent. I will guarantee you our setup will last a lot longer then prebent 16 gauge stainless. Quality is more important then quantity. Our business is not run like corporate *****. We care for quality and customer satisfaction.

Oh, trust me I know all about schedule 10 and its reason for use. I've been involved in manufacturing mass production pieces for a while now (and am always looking for new clients). I'm simply trying to help you out because I'm an enthusiast above all and live by the motto work smarter not harder. I want to pass down a couple of things I learned along the way that will help save you time and money. Schedule should really only be used for manifold applications, due to the thickness and the resistance to hydrogen embrittlement of high temps, you'll never see those temps after the header and if you do there's obviously other issues. Ill give you a prime example of overkill and why it was switched for 16 ga tube. A major schedule using manifold producing company used sch 40 to make an after header kit for subarus but came to realize all the weight was unneccesarry and switched it for tube which cuts down on weight, fab time and cost (everyones best interest at heart). And by the way the pic you posted of the feed pipe by itsself clearly shows its not backpurged or if it is its done incorrectly. There's alot of oxidized filler going into the the lower wastegate
Making a first kit custom for trial purposes is ok but when it comes down to making a kit that can be replicated you're going to find a lot of stuff will have to be done and you'll be paying your fab guy a lot of money to fix that stuff. If you think you can justify the cost of having a fab guy cut and weld schedule vs working with tube you'll regret this whole turbo kit idea.
I can appreciate the whole pride thing of wanting to produce top notch parts, however when you start itemizing your kit you will be in shock as to how much money you have in fittings and hose, material, not even so much component cost (turbos and wastegates). People will pay for quality but to make it worth your time a complete kit should sell at the $9500 dollar range. If you are truly serious about marketing your own brand you have to start thinking about the ultimate cost which I can guarantee is a lot higher then the number you have worked out in your head.

JTran is building his kit the same way my CGT kit was build..... The only difference us JTran is charging 35k less
....That goes to show you the real passion this man has for his work.Hell.... The last few times I went to his shop.... I had to demand he take payment for the work he did on my car... His staff is the same way.... They are a different breed.... Collin is their fab guy... Everytime I go to that shop... He has something new to show me... The guys welding skills is far beyond anything I have seen .....
So it's funny when I see someone on here telling him not to make super high end kits.... That he should lower the qulity and make more money...
.Go meet the guy before coming on here telling him how to run his business.... and you will understand what he is all about. ....It's shocking at first .... but when iu see what he is about you will understand.
