Then do ur own test man its annoyin when people come on critizing, if its a problem do ur own test

Makes me even more excited about the other thread I started showing the awesome stock ported/coated parts I received from Dave today.

Uh, hmmm, crap, what to do now? Here it goes.....haha.
Just tested that EBAY crap. Well guess what, it isn't such crap. Damn it, I hate to even post this! haha
That darn O2 housing actually works! I cannot believe how much the car picked up. It really opened up the exhaust flow. I have the high boost actuator on the car with the boost controller turned down all the way. Boost has been 21-22 psi peak. Well we threw the EBAY O2 housing on the car and the boost picked up to 22.8 psi. There must have been more restriction there than I thought. Not a huge gain but some. The gain was in the HP and Torque. It is almost not believable. The Full Race header is still on the car. We are swapping it back off right now to put the ported manifold back on. It will be interesting to see if the restriction in the 02 housing helps the header flow more or will help the manifold too.
Below is the dyno graph. It's pretty amazing. This is on PUMP GAS and has been all day! The car gained 13 whp and 12 ft lbs of torque.
This is a part I have absolutely NOTHING to gain by saying it works. I can sell the RNR stuff I can sell the Full Race stuff but I can't sell these! Damn it! haha
The truth is the truth, I don't lie about testing and I don't fudge results. This is wether I can profit from it or not.
I just hope a part like this doesn't crack and break as I would think it can't last as thin as it is. Sure makes some impressive gains in power.
Increase from 3900 rpm to 7,000 rpm. The increase in boost is probably most of the cause but I CAN NOT decrease the boost level more than it is. The boost control is backed off all the way and it is running on the actuator only. Inteteresting fact is the knock count did not increase at all with the increase in boost.
Enjoy and stand by for one more manifold test. This freaking header is HOT HOT HOT. Tough getting it off the car.

Wow, that's amazing. I guess the real question, as you stated, is will this O2 housing stand the test of time and not crack.
One other clarification, Dave, were you previously using a stock ported/coated Buschur O2 housing just like the manifold? You had only been talking about the manifold being ported/coated before, but I'm assuming this whole time you had the ported/coated stock O2 housing on as well, which was replaced by the untouched Ebay O2.

Nice findings!
So Dave does this mean you will be porting the stock o2's even more or even making your own o2 housing? I'm sure there'd be a market for this.

Is that correct?

I once spent an entire day trying to call RNR. At least every half hour I got a busy signal, it never once actually "rang".
Not bashing RNR, just stating.

First, yes,the turbine housing for all this testing has been a single flapper 10.5 ported and coated and the 02 housing has been our ported/coated unit.
Second, we already pulled a 02 housing off the shelf to try to make larger than we have been. I am worried that making the casting too thin will cause it to fail and crach eventually, that is why they aren't larger than they are already. There is a point that you cross on things like that that could come back to haunt you. We will be testing a new housing next week though to see if we can enlarge it enough.
We already swapped the manifold back on. Did three pulls. No tuning changes. The boost is also up, as matter of fact it now hit 23.00 for an instant. So the O2 housing was for sure a restriction in the system.
The new dyno chart is below. Spool up for the Full Race header compared to the Ported/coated manifold is still identical. After 5300 rpm the Full Race header makes more power than the stock ported/coated manifold. The difference isn't huge, the header is now 4.1 more whp and 3.2 ft lbs. It was consistent on both runs though so it is a gain for sure.
That's it. 6 pm, we are closed and going home for Christmas. This will conclude our header testing. We cancelled the order on the other header, DC Sports, that we were going to test. I want my car together, I have other things to do to the car and test.
If the RNR header was easier to install I would give it another shot. Bottom line is the gains stayed consistent no matter what combination was tested so I don't see the minor loss in low/mid range with the RNR header to improve and power up top, while it may increase still shouldn't exceed the manifold as it didn't before. In other words, don't cry, I'm not re-testing it
Our ported 02 housing I will test again as it is something I think we can improve and we do sell quite a few of them. I'm honest but I'm not stupid
You all have a great Christmas!!
There's the sheet.

badazz, yes, what you said is correct or so it seemed.
RNR's reputation isn't at stake. I don't feel what I reported was derogatory at all. The nothing gained much for power except for that darn Ebay part that none of us vendors sell!
