That statement was quite ignorant actually. No one is BS'ing online, just stating facts from my experience. Great products, that fit well right? Not perform?
And yes, we already know how much they love using their phone instead.
Here's an excerpt from the WORKS newsletter:
WORKS has spent numerous days and thousands of pulls with a wide array of EVOs, Eclipses and
others strapped to various brands of dynos compiling data. However, some cars (such as the
WORKS Time Attack EVO) have never seen a dyno. When parts undergo dyno testing, it takes
more than one session on any given day to compile a data set that can be statistically compared
with others. One day may show a 20 HP gain while another may show 18 HP or even 24 HP. It
takes numerous tests to determine a “true” number and even then there will be some variation
depending on the test conditions (see above article). Because of these fluctuations, we often elect
not to publish hard numbers with our products. For the gains/ratings we do distribute, these are
usually on the low side of the range of repeatable results we have encountered. Some of our
customers will take the liberty of testing WORKS components on their own vehicles and often
report back with gains higher than expected.
There are also other variables that are often hard to display using a graph, spreadsheet, etc…
Some of these include: fitment, quality of construction, durability. WORKS prides itself in
achieving a balance of all of these aspects in order to bring the finest goods to market. They may
not be the shiniest, the stiffest, the lightest, the thickest or the most powerful item available—
although in some cases they are. What WORKS does make available are products that have well
rounded characteristics that improve performance, drivability, handling, etc… not only today, but
for years to come.

What is the other host of mods that were done during the hotside/WORKS o2 housing install?

I have much MUCH respect for AMS, and I will be buying a few things from them (hardpipes, intercooler, etc) (oh wait jason, I forgot I was a fanboi...tard) but my point is, buscher has said many times in his own testing that using sae correction is bad juju. It does in fact skew the numbers up or down. We want raw data. I have a friend that used to work for dynojet as a salesman. Dynojet is based here in vegas for those that dont know..but the point is, he could "sae correct" a good amount of horsepower on pulls. Its not like he could add numbers in, but if you run sae 1, and the power goes up, sae 2 and 3 the power goes up more, use those instead of the raw. People want to see power, whether its real or not.
As far as the fanboi comment. That cracks me up everytime. So let me get this straight. If someone buys buscher stuff because they want the best bag for the buck, theyre instantly a buscher fanboi? And if someone buys works stuff for the quality, even if it costs more, they are a works fanboi??
Well guess what dude. YOUR DAMN RIGHT IM A FANBOI. I'll be a fanboi for every company that I put parts from on my car. What you dont realize is, anytime you pay a company for their parts, and install it on your car, your a fanboi.
I think the word you should be more concerned about is wannabe. You know, like when you have a mercedes screen name but post on an evo board with no mention of a mercedes in your sig? I mean you mention your kawy, so you must not even own the amg...

I sold the AMG because I prefer the interaction with the Evo although if they put the 6.3 in the C-chassis I may have to get another.
So now you are not only a pathetic fanboi...you obviously have so little of a life that you obsess offline about me calling you out. What a loser.

AMS front motor mount, head studs, and an AMS fuel rail.
And I am officially done with this thread.
Like all WORKS products, we have clearly defined goals for each product we design and develop. Of course, there is performance and equally important are fitment, safety, and durability. WORKS products are designed to fit and last as long or longer than the corresponding OEM pieces. In many cases, the OEM part works well and cannot be improved upon. We have ‘pulled the plug’ on many projects after months of R&D only to find the stock Mitsubishi parts worked best (i.e. after producing three prototypes of the air intake).
When we test our products, one of the tools we use is a chassis dyno. When we do full RPM sweeps and fixed load testing, we are only concerned with deltas or the difference from run to run. Many years ago we realized you cannot rely on the ‘numbers’ chassis dynos were generating because the same vehicle on the same day would produce numbers varying up to 10% on different dynos. A solid chassis (or engine dyno) in a climate controlled environment will produce consistent readings where minute changes will be reflected in the results (minus the tolerance built into the dyno and/or software used to control the dyno). Therefore, the only valid results occur on the same day with back-to-back runs. Yes, the engine components are very hot but to get proper results, you have to change the part(s) right there on the spot. Then you have to bring all of the other fluids (gearbox, diff, etc.) up to normal operating temperature before collecting reliable data.
For example, earlier this week we dynoed a 4G Eclipse and established a few baselines before beginning our testing. This was done with the same exact set-up on the same dyno a few weeks prior and the results showed 19 HP LESS at the wheels than the previous session with NO changes to the vehicle. This is the norm. In fact, if the results are the same when we go back on the dyno on a different day, we question why. The moral of the story is that chassis and engine dynos can be useful when testing on the same day with back-to-back runs changing only one variable at a time.
WORKS products (including the cast O2 housing) are designed in conjunction with all other related WORKS products as an integrated system. For example, the WORKS downpipe was designed with the O2 housing allowing a direct path of airflow from one part to the next. Most downpipes we have experienced exhibit some other flow pattern or disturbance when transitioning from the WORKS O2 housing into another Brand X downpipe. We cannot vouch for the dozen other brand downpipes currently on the market nor any other products when used with WORKS products.
Although anyone is free to mix and match companies A, B, C, X, Y, and Z, we cannot guarantee that our product, or anyone else’s in that system, will perform as promised. Especially when many (if not all) of these parts were designed with their accompanying parts that were replaced with a different brand. Would you install four different brands of wheels on your EVO?
One thing that needs to be understood is that WORKS products are part of a fully integrated system along with the WORKS P2 flash which is the backbone to all of our engine power upgrades. Without the P2, we have witnessed boost issues not only with our O2 housing but other O2 housings as well. Therefore the moral of the story is we highly recommend integrated packages from us (or any other single manufacturer) with the proper tuning including boost. Reputable tuning companies frankly don’t have the time and energy to properly tune WORKS products and visa versa. Always stick with the tuning designed for your system of products from a reputable manufacturer.
Online forums are a great opportunity to communicate with the community; not only in the automotive world, but with just about anything. Unfortunately we are working around the clock and extremely busy with testing and development. In fact we just hired another full-time mechanical engineer to help with product development. We wish we had more time to dedicate to the forums but there are only 24 hours in a day and only 7 days in a week. The joke around here is that when you step into WORKS, you have just entered a time warp. One week goes by and it seems like one day!
WORKS’ philosophy regarding forums is to be strictly informative and educational. We like to publish information about products, services, and events and will not contest issues that no one ever wins anyway. These types of outbursts are very time consuming and take away from valuable product development time. However, we welcome individual questions, comments, and support (including the authors of these threads) via email (info@worksmitsu.com), phone 415.641.9675, or through your AWD (Authorized WORKS Dealer).
As the first US EVO tuner, WORKS is currently dedicated to the Mitsubishi platform ONLY and we have a total of 7 EVOs in-house owned and operated by WORKS and our employees. We only release products that are tried and tested that we would put on our own EVOs. If a product doesn’t meet our goals, we have no problem scrapping the project. Rest assured, we would not release products that would sacrifice power or fitment as we design everything that we install on all or our own EVOs. WORKS does not produce products for all different types of vehicles to make a quick buck. Our heart and soul is with the EVO, which is our passion.
We have taken the time to develop a superior cast piece similar to our European counterparts like Alpina (BMW) or AMG (Mercedes). The bottom line is that the WORKS cast O2 housing will fit better, last longer, and perform better (if tuned properly) than anything else currently on the market.
Due to overwhelming outcry, we have chosen to post this graph this one time.
The graph was performed in the May of ‘05 with the WORKS Exhale turbo-back and P2 Brain Flash on the same day.
The baseline curve was the highest repeatable run while the WORKS Exhale Cast O2 curve was a moderate repeatable run. Temperature 74.1F-75.2F, Barometric Pressure 30.07-30.08 In.Hg.
