I'm using www.performancecoatings.com ... $100 to coat the manifold in 2000 degree Satin Titanium.

I got my manifold long before the O2 was offered, but I will be in contact with them about one.

 

Any updates on how this piece is holding up?

 

No one has posted a failure yet... the O2 housing is a paper weight. A crap design at best.

 

y is the 02 housing crap? just curious also wondering how people are doing with this all installed etc after u got it coated did u still have to cover the radiator hose etc from the heat?

O2 is crap...

 

Why is it crap?

 

sorry to revive a dead thread with joe but zeus why is the o2 crap in your opinion?

 

I wasn't sorry to revive it...

As far as the only reason I can describe that it is not as good is stock is because it is missing the bracket that bolts the O2 housing to the block. The lack of this bracket puts all the weight of the manifold,turbo, O2 housing, and downpipe back to the manifold. Other than this I don't know what Zeus is talking about.

 

A decent set-up would include a turbo support bracket. I have never seen a setup without one.. as long as you are using one of those there should be no issue with weight cracking the manifold... only heat. Just my .02 would be this whole thread is why people do pay the extra money for well known manufacturers of headers and any other piping... some dont matter (Cat delete pipes, and cat-backs) but as far as a header and o2 housing are concerned... wouldn't it be nice to know that you have something that is great, well known and some of the best are using it with no problems? There would be no 4 page thread about how it is holding up or, did it actually work out ok and fit alright. For the extra few hundred bucks I think it is better to get something you don't need to worry about and something you know works well.. I like this quote from AGP,

"The bitterness of poor quality lingers long after the sweetness of cheap price is forgotten."

 

I just took my Ambien and Geritol so this is going to be short...

If we are talking about the SSAutochrome O2 housing, the exit flange is too small... smaller than OE, so the OE donut gasket doesn't fit (falls off when inverted). You will have to balance the gasket on the downpipe to make it work (poorly I might add), unless you have a flush fit/flex piped downpipe. In the second case, the mismatch is so great, that I see a real turbulence issue. Last but not least, unlike the Helix, or some others... the housing is not divorced, but the WG dumps right at the flange. I'd be willing to bet that those who are seeing a difference in power at all, are seeing it with housings that have the main exhaust gas divorced from the WG dump.

 

uhm... the turbo support bracket is not present on any of the o2 housings on the market... it's not even necessary if you're running the stock cast mani. in the case you're running an aftermarket hearder the weight may become an issue but then your header comes properly bracketed.

zeus has tried his best to crack the ssac mani... he hasn't done it... he's prolly referring to the crappiness of the design o2 housing as in it does not divorce the flow of the wastegate and the turbo outlet... although i'm not sure if this is tru or not... he seems to be pretty sure. by the looks of it... the gasket would suggest a divorced design but i haven't bought the damn thing.

 

here is the manifold i got off ebay. not sure yet how it will hold up but it looks very good. Just got it back from www.calicocoating.com today.

 

That doesn't seem to be equal length. As for the support bracket I was talking about for the manifold, not the O2. Techinically it supports the turbo to the block, nothing to do with the O2 housing. Some Ebay parts are great for thier price (Downpipes, Cat-Backs, etc...) but when it comes to something that actually needs to be engineered (Intake Manifold, Exhaust manifold, O2 housing, etc...) I would prefer to pay the price of something that I don't need to "Test" and find out down the road.. I would much rather spend a little more but get a part that I know works well. I just couldn't imagine buying a part that god knows who put together and hoping that it is working well. Look at big Dave Buschur... he made a quick exhaust manifold and tried it out and lost plenty of spool-up and didn't gain any HP.. techinically lost it. He knows what he is doing. It is an extremely complicated task to creating an intake manifold or exhaust manifold. You need to know a decent amount of information.. not just take some pipes, bend em up and make em fit, then polish them and sell them for $350. I could get my local exhaust shop to do that for me probably for half the price. I dunno.. maybe it is just me. I still like the saying,
"The bitterness of poor quality lingers long after the sweetness of cheap price is forgotten."

 

nice quote Trina. I don't know why people try to justify their cheapness when they purchase junk for their car.

Manifolds need a LOT of engineering. Even if they are even length, doesnt mean they will perform well. That level of engineering is dizzying...suffice to say, most don't go there

 

I think they should make it a rule on the forums that unless you have that part in question then you cannot talk in a thread, and then there will be a seperate thread for questions. You two jump to conclusions way to quickly and especially not even owning the part I find it hard to imagine that you can judge it so easily.

I have the ssautochrome manifold that wprettyboy had coated. Let's make some very basic conclusions. The tubular manifold will flow better because it is not cast and does not have the rough casting surface like the stock manifold. Also this header is very well made. It is as good as the MR manifold OR the EVO8.com manifold that look almost the same. A TIG weld is not that much different from a MIG weld as far as strength. Next is the wall thickness, and it is as thick as the expensive JUN OR Borla manifolds so knowing that it is SS304 it should be as good. Next the seller ssautochrome seller is offering a lifetime warranty on this piece. Which means 5-10 years or 3 months down the line if anything happens you get another free and only have to pay one way shipping charges. Most other shops have a one year or no warranty on their manifolds. Next is how some people talk about how this is like the Honda manifold that was posted in another thread that cracked. Well this is just not true, quaility is much improved here and this is a decent piece. The only noted defect so far in this manifold is that a few people have got them and the bolts don't line up to bolt to the turbo. This is an easy fix and it can be sent back to ssautochrome. I heard about a Borla manifold trashing a guys stock turbo...ouch! I haven't heard about one of these yet trashing a turbo...so far so good!!

The only thing that worries me about wprettyboy is that if he didnt install and heat cycle the manifold his coating may crack and peel and he will have to have it redone. The "chrome" finish flakes off after a week and so will your coating.

As far as the O2 housing being poor, the only thing essential poor about it is that it does not have a support bracket to hold it up to the block like the stock piece. It is evident that this is required as that the weight of the header, turbo, and downpipe all weigh down on the header and without the support of the O2 housing your header will crack much more quicly. This only makes sense. Ok one more thing to add about the O2 housing is that the area not being divorced is OK. On DSM turbos it has been common pracitce to cut out the area between the wastegate and outlet on the hotside to reduce boost creep. The same idea could very well apply to a twin scroll EVO8 turbo because well it is still a 16G.
