I never called you an idiot. The Cobb and Injen do not use it, and I only listed the modified ganzflow design because it utilizes 3" intake volume instead of the 2.5" that the stock airbox uses so its only partially using the same design.

This only works with 00-04 MAP engines, as all the previous models have different intake designs and work in various other degrees in terms of airbox designs.

Go read these if you want to learn more about previous intake discussions:

Yet another unsatisfied Weapon *R customer. First get rid of the POS filter that came with the intake. Then if you are intent on keeping it, I'd try to run piping down through the fender and make your larger airbox in there. Might be a little more work, but at least you will end up with an actual cold air intake instead of a band-aided J tube. If it were me, I'd try to get my money back and buy an Injen. Not to be an ***, but it pays to do your homework before you buy something.

Ya, but that box does not have to be at the throttle body. It can be anywhere along the intake. If you look at some of the earlier Subaru models, they were all by the fender. It's unlikely that you'll be able to tell a difference based on where you put it. You may be a Mechanical Engineer, but I'm an Aerospace Engineer.

VR4Impreza, YOU are posting all the anecdotal evidence anyone needs to see why not to buy this intake. You just posted a complaint about the lack of power and response your car has with this intake. Why are you still complaining about the lack of so-called "data" supporting the assertions of so many experienced people that the Weapon-R and others like it are pure crap? The intake you are using has no provisions for a plenum, has a large diamater tube, and draws hot air from the engine bay. Expressed mathematically, it goes as follows:

Hot air + no plenum reserve + slow port velocity = SLOW CAR

Yes, you have maybe 2 more hp above 5000 RPM. Great, but by the time you get your car to that point, the otherwise stock RS you're racing is a car length ahead. If you want a high-RPM car, go buy another car. You're losing every strength of the Subaru N/A horizontally opposed in order to slightly improve its weakness.

 

Heat soak from the engine.

Happy now?

 

I normally do not get in the mix of a simple problem of intakes, but I have to throw in my 2 cents here.


Okay lets calm down.

I say when other members give free advice from what is factual with threads to support their claim, then I would at least listen coz they are not here to **** anyone (members specially) and beat a dead horse. They are here to help ..

In your case with the Weapon r intake gain or no gain, I say intakes are always in question and being a shop and a store, I will install anything my customer wants period.

But if I am asked what is the best or what works, then that depends on what it is you are after performance wise.

To each his/her own but dont ask help then get upset when the replies are not what you want to hear.human nature I guess lol..They are here to help and you decide what you need to do.

Now we can help you keep the Weapon r intake but it has to be tuned to your set up is all, then you get what you want result wise and it will make you happy. But if no tuning is planned then think of your options wisely.

Data logging with test drives along with other test equipment is the best way to see if that intake will yeild gains when tuned . Most dyno tunning are done on WOT and 3rd gear usually.

We love a good HP/torque graphs that climbs early and shoots straight up lol....heheheh. We do not care much about HP figures, driveability is what we are after mostly.

cheers mate and again we are not the enemy okay

I should say why you should place it farther down I suppose. You put it right on the TB and you have a big container of air sitting right on top of the engine. If you put it in the fender it will be cooler.

If you are going this route, I would be interested in seeing if there's a way you could add a velocity stack inside your new plenum. That would be nearly ideal actually.

 

It doesn't really matter where you put the plenum as long as the airflow into the plenum doesn't stall and you have a full radius inlet for the tube that connects to the throttle body. It would be easiest to make an intake like the FLATT intake (a straight flow muffler type design.) You can buy transitions from Burns Stainless and that will make building it much easier. So what you do is cut your J bend tube and weld a 3" to 3 1/2" transition to that. This will then have to have a flat circular plate with a 3 1/2" ID and a 5" OD welded to the straight section of the transition. On the opposite side of this flat plate you will need to make a full radius lip. This is welded to a 5" diameter tube (the plenum) which has a similar transition on the other end that connects to a 3" diameter K&N fiter (or similar filter with a velocity stack.) All you have to do then is make a heat shield for the filter. It's really much simpler than it sounds.

 

A full radius inlet does not have a sharp edge where the air enters. If you look at a current F1 engine velocity stack you'll get the idea. I don't know about the Weapon R filter- some of the K&N filters have them and some don't.

 

Sorry to butt in, but I am looking for an intake for my 98 impreza outback sport (2.2 w/ MAF) Before I read this thread, I was planning to get the Rallitek intake system. Now, I would really like to find a CAI that incorporated the MAF inline like the Rallitek and Weapon R, which I have yet to be able to find. There is also a Ganz flow designed for my model year, and it does not eliminate the stock airbox and incorporates the MAF sensor in line. This is the first significant mod i have planned for my car, and I would like to find the intake system that most fits my needs. I dont exactly race my car; I just want a little more get-up-and-go. But I'm not willing to sacrafice a whole lot of low end power -and none of that stalling/hesitation crap.

So for all of you with experience in dealing with N/A subaru intakes... can you please give me any advise or recommendations? ... anything would be helpful
