obx tubular manifold

TO be honest I weighed things out for the maybe faster spool and 5 extra hp it's not worth it on a car that I will prbably have 250whp tops if i'm lucky. So depressing after just parting out a potential 450-500whp awd project :(
 
So then what the hell is that thing?

No need in bringing back dead threads, especially to ask questions that clearly point the obvious fact of you having not read any of the posts :nono:
 
Here we go again...

:rolleyes: no one's claiming this to be anything yet besides I think the video shows it's possible. Does look like the same guy that the pictures in the bigging are from. Why don't you wait till we figure out what he had to do to get it to work before we come out with the skeptic POV's
 
Ask Concept Illusions as they obviously had to fab up something for it to fit because those pics I posted were from them on a customer's car (video you posted).

Still not worth the time or effort to make that piece of garbage fit.

WOOOOSAAAAA man

Did obx like kill your brother or attack you or something cause you seem to be real short with even the possibility that maybe it's not as bad as we thought to make it work. The main proof that it wasn't gonna work is the same customer that obviously it does work for. So If th only person to try got it to work and it DEF looks better than a log and I wouldn't doubt performs better even though you insist it's a POS then why not atleast find out how they made it work before you bring out the mob.
 
It's a moot point. OBX doesn't make them anymore (undoubtedly because no one is willing to do THAT much fab work to get them to fit), and they weren't produced long enough for there to be a sizable amount on the resale market. There are some new designs coming out very soon (*hint**hint*), so just hold your horses.

Hey Paul! I heard August! You know what I'm talking about.. :sneaky: :thumb:

As for the OBX manifold. I can't figure out why people are so against them either. It's a tubular exhaust manifold. Yeah, you need to do some cutting here and there. But to some people, that's nothing to sacrifice for better spool and overall performance. Hell, if I didn't have faith in Paul I'd probably buy one. Not because it's a pain in the ass to install, but because the performance gained over my current log manifold might be worth it. Just saying, to some people, a little zip tuck cut here and there isn't going to deter them from buying somthing with a better flow and overall performance. So you have to move the T-stat housing to the left a couple inches, big deal. Extend the bracket and lines and it's no longer an issue. You could make a heat shield for it even if you're concerned about the heat soak. I GUARENTEE if these were all flow tested and OBX stood on top, MANY 2GNTers would be buying it, therefore dealing with the modifications to make it fit regardless...

Not everyone buys %100 ready to go perfect fitment chromed out parts right out of the box. Some people just don't care if you need to modify it for fitment. Me being one of them.
 
It's not that simple... I'm sure that ram-horn design probably flows better than 99.5% of any other manifold currently out there. My main concern would be for longevity. I, like many others, have no problem with modifying my thermostat housing for some amazingly well-performing manifold -- I mean, modification, isn't that what this is all about? I just don't want to do lots of work for a manifold that'll probably crack because the manufacturer used a crappy alloy, thin walls, and an all around poor structural design.

Most of you are only looking at a single facet that makes up a manifold -- there are many features that must be taken into a account when buying a good manifold.

So true paul but I liek I said in my earlier post I don't see a 420a at 250whp or less running maybe max 10psi pushing the obx to the limit as I ran a XS power mani with a 50 trim(yes I know trim is not a size but think fp green) at 20psi dd and it held up just fine.
 
I agree with Paul... you spend X amount of time working on getting it to all fit properly with whatever modifications you have/want to do to your engine... Sure you might have a great setup for a few weeks, few months, hell maybe a year... but seriously, a cheap steel manifold, how long is it going to hold up... only one way to find out... but I speak for myself now, I'm poor and I'd rather not spend the couple hundred on this manifold, it break in however amount of time it takes, and I'm left with a few peices of metal that I can't really use... Repairing it will just become a hassle...

Exhaust gas pressure does play a role, but more importantly, the countless heat cycles coupled with a cheap alloy and thin walls is what concerns me. I'm sure the XS manifold did hole up fine, but for how long? Six months? A year? I bet it wouldn't last much longer than three years, if it even made it that far.

The types of failures I see happening with the OBX manifold won't happen overnight; they'll take a while to develop. If you want to buy a new manifold every year, then go for it; but I always try to look for a solution as permanent as possible.

Your right. The thing people don't understand is diffrent people have diffrent ideas of what's worth it and what they can afford. I have a descent amount of "fun income" so for me a manifold that last a year and makes my car drive perform like I want it to(that's assuming it kicks at a year as my xs held up longer than that) it's worth it to me. I don't usualy keep my setup the same for a year anyway I'm constatntly changing shit anyway. Diffrent strokes
 
So you stitch weld around the seams of the runners and flange then get it ceramic coated. It'll prolong the damage from heat cycles and create a stronger piece.
 
Why bother? At that point you're putting more money into a crap manifold than it'd take to buy a good one. Plus, with those thin walls, it'll probably end up cracking along the runners if the welds are reinforced.

If you were going to ceramic coat the manifold anyways, it wouldn't be a waste of money. In fact, it would actually improve performance, durability and reliability.

A couple spot welds would improve strength pretty well, though.
 
If you are going to put all that work into trying to a cheap manifold to work, might as well fab up your own. I don't see why this is still being discussed. For the type of material it uses, the R&D (if any), and the price, it is not worth it.

Paul, please speed up this project of yours so we can finally have something to show of quality to these people.
 
Heh. OK. I know what a quality piece is. Trust me.

But no one has even tested this manifold enough for ANYONE, I meen ANYONE on here to say it's a piece of shit. Right now, every single one of you whom say that are stating an OPINION. It doesn't fit, big deal. Make it fit. The general purpose for buying this part is to increase performance, not buying something that must, HAVE TO, NEED to fit perfectly. If it increases performance, who cares if you need to make it fit?

Until someone puts it on to flow chart, heat cycles and material tests, no one will know. Period. It could be the best flowing manifold in the world for all we know.

All I'm saying is, none of us know for sure. If you need to improvise then so be it, you'll still see the same performance then before you modified it.

Seems like everyone knocked it from the get-go because you needed to trim a piece from the T-stat housing and dismissed any potential it may have had you put some elbow grease into it and making it fit and actually testing the manifold for true results.
