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

My car on the other hand is making as much power as possible and doing it through the 2.5" SS housing. If there were going to be gains it would be more likely on a car that was possibly already testing the limits of what was being used.

Also, do you think these housing could have made more power with tuning? I understand that your RS is tuned to the max with the Ebay setup, I do wonder, however, if the 3" O2 housings reduce backpressure enough to make the engine less knock prone and allow a bit more timing.

I'm still wondering why the HP curve is totally flat from 5300 rpm on...

I've messed with the smoothing on a mustang dyno, it doesn't do that.
As one of the first owners of the Works o2 housings, let me say that I am NOT upset.
Does it make more power than the stock piece? YES (with the exception of revvin9k)
Does it fit every bit as well as the stock piece? YES
Does it look EXACTLY like the stock piece for a stealthy appearance? YES
Will it last forever and a day? YES
How can anyone say this is not a good part?
As far as price is concerned, think about it. The eBay housing is a bargain, the Works housing is not. NOTHING from Works is a "bargain alternative". You should have known that going in.
Why is anyone here *****ing about price? Paying more for something is in no way a guarantee it will make more power. Sometimes the bargain piece makes more power, kind of the way Evos tear up Porsches out at the track. Sure the Evo is faster, but you know that Porsche is a hell of a lot nicer to ride in. Sure the eBay housing made a whopping 3 additional HP, but the Works piece is STILL the better part. Like anything, it's about more than just power, especially when a 5-degree change in ambient temperature will make a bigger difference than 3 hp.

Be that as it may, when something costs 4.5X as much as the alternative part, then makes LESS POWER, the little features of fitting nicely and looking "stealthy" really go out the window. Those things really aren't valuable when you could port and coat the stock o2 housing and make similar power for less than half the price while retaining all the same things you mentioned. The Works should be maybe $200 at most.

Besides, the Works part was researched and developed in the US, it's the only true cast iron housing on the market, they were first to market and it's not made in China like the other Ebay housings. Big differences there.
