anyone know what they used for the main pipe section (guess i could call it a collector but use that term loosely).

anyone use one of these?

no, I dont think anyone has used any of these, but I will let you know that that thing will flow about as good as a cardboard box and get really hot too

it looks like he just used steel square box tubing for the "collector" part...

I am sure it would work fine, although I dont like the design, all the gasses are pushed into the square plenum then they will find there way to the turbo as the path of least resistance, but the cylinder on the left has to push its way past all the rest of the gas... at least on the standard weld el manifold the gasses are directed a little bit towards where they need to go...

that looks like a real homemade manifold, it looks so easy to make. but it seems like it will be too restrictive.

$330 paperweight. That's the worst design I've ever seen in my life......that manifold is something they would've used in 1910.

carefull what you say, a memeber of this board HAS used a manifold simualr too that ::) i wont name names, he will let him self be known if he wants...

I'm not trying to be a dick. just being honest...terrible design.

Re:intresting and simple manifold on ebay... questions about it.
 

i'll agree it doesn't appear to be a great design... but this is something i'd have no problems fabbing at home... could prob use a round pipe instead of the square and that would make it more effective... but then again working w/ round piping isn't near as simple for drilling.

i'm sure i could do the weld-el type manifold also... but that has a lot more prep work that has to be done.

The lowest I'd go is weld-els. The exhaust manifold design is WAY more important than a lot of people make it seem. I can't believe how many people put an external wastegate that only vents from the #1 cylinder. it's crazy!

Re:intresting and simple manifold on ebay... questions about it.
 

more like just bad manifold lol.. and you thought a hf mani didnt flow haha. i will stick with my equal length.

think about what your waste gate is doing.. why the ---- would you put it on just one runner???

i guess if your just selling them and not using them on your own car or something.
