Back to back testing of Invidia, Ebay and Works 02 housings......

You can go buy your clothes at Mervyn's too and watch them wear and fall apart every other month or go buy quality items at a Marshall Field's where they will stand behind their product they sell and exhange that product a year after the fact and give you something new no questions asked.
I could also go buy a pair of sunblockers for $25.00 or buy a pair of Maui Jim's for $250 that offer the same performance but will fit better, have a better wear/finish, and not fall apart if they are dropped once.
If buying "designer" means I have less hassle then so be it. Your observation offers no conclusive facts/evidence to show this to be the case.

put the bracket there for a purpose.you can run still run the car with 4/5 lug nuts on the wheel.......i wont
I thought that the ebay O2 housing made 13WHP more but it did it on more boost. Basically the O2 housing didn't really make power but it helped reduce knock (on DB's car).
On a street car tuned at 20 psi on the stock O2 how much different would the power level be at 20 psi on the ebay O2?

a coated Ebay O2 housing might not be to bad.

It's obviously nothing like running on 4 lug nuts.

Price is one of the many litmus tests for buying a product.
You guys can argue your points trying to convince the other of your argument until you're blue in the face, I couldn't care less, however, matters of perceived value and the price someone is willing to pay for a given product are ENTIRELY functions of personal opinions, preferences and prejudices, so NO ONE is going to view things the same way.
It's all arbitrary based on who you're asking and what color socks they're wearing that day.
The power levels are almost completely irrelevant to the cost arguement. Yes, David provided a baseline/control and his tests, and thank god for him stepping up to the task, however, if AMS (used for sake of argument) posted dyno figures of the EXACT same test, conducted under virtually identical conditions, yet they saw different results, or even the same placement of the products in the "horsepower hierarchy" but with different actual numbers, this forum would be in an uproar over why, and for no good reason. Different car, different day, different dyno, different tuning, different complimentary modifications, yada, yada, yada.
People should buy what fits ALL of their own personal requirements for cost, quality, fitment, performance, reliability, etc. and completely ignore useless comparisons based solely on the personal opinions of the individuals providing the comparison.
David's test provideds great information, no doubt, but it is only ONE factor for each individual to consider when they are making their personal choice to spend their money how they so choose, which should mean nothing to the rest of us.
It's simple economics.
What trade off's/sacrifices is one person willing to make to get what they want.
- You can't use the OEM housing (unmodified) and expect to make lots of power.
- You can't buy the Works housing and expect a price less than $450 (whether you think it's fair or not), but you'll get some added engineering.
- You can't use the eBay housing and expect the addition of a support bracket or the highest quality manufacturing or materials.
- If you buy the eBay housing, you run the risk of potentially having to replace it later on, though at a lower price point than the competition.
- If you buy a more expensive housing, you will spend more money up front, but are all but assured of not needing to replace it.
etc. etc. etc. etc.
Personally, I'm going to port and coat the stock housing, but what each of the rest of you decides to do is up to you, and I don't care to read any more arguements about it!

PLEASE DO NOT bash Works. There 02 housing and the Invidia WOULD be a gain over the stock unported housing for sure!!
In my last testing I went from our ported/coated stock 02 housing to the SS Ebay housing and gained an additional 13-15 whp OVER our already ported/coated stock housing.
This means that the Works and Invidia is worth a minimum of about 9-11 whp over stock.
Bottom line, as I said is the large housing just isn't needed on the stock style turbine housing and the 3" outlet flange does nothing.

Two questions:
1. How much of a WHP gain over the stock o2 housing is the ported/coated o2 housing you offer?
2. I don't understand one of your comments above. You say the SS Ebay is worth 13-15whp over the Buchur stock ported/coated o2 housing and then go on to say that the others are only 9-11whp over a plain jane stock o2 housing when all the testing was against your ported/coated stock o2 housing to begin with.
Can you please clarify? Thank you.

Great work and great write up Dave. Props to you and all the companies out there. One question about which o2 housing on ebay to buy. Theres different kinds and some come with the exhaust manifolds as well and i was thinking about buying the one that comes with the manifold, and about to cancel on my helix o2 housing. Thanks in advance!
Don't buy the manifold, because it is likely to crack and won't make as much power as porting and coating the stock manifold. This is per Dave's other dyno tests. Dave himself sells the particular o2 that is tested in this thread.

The Works housing we all can agree is a fine looking piece, no one denies that. Not worth the $450 IMHO.
