Default BAD choice of intake?

hey,

i ordered an AEM short ram intake for my RS impreza, i obviously didnt do much research before ordering. Now im having 2nd thoughts and regrets as i read it is crazy loud (honda-like) and performs the same as stock pretty much.

So my question is weather anyone here knows about how well short rams perform on imprezas? and if anyone has a AEM intake installed can you please let me know what you think of it?

thanks

sound - new intake = very loud intake noise lol, cool if you have a turbo, but on the N/A motors i find it can be kinda whiney

Performance - did you give your ECU a reset after you installed it?

I've heard good things about some of the AEM products, but i havent heard anything about the short rams yet. It would be good to hear feed back on them though as I have been thinking about getting them as a supplyer for my company. (i'd sooner go with injen though as i have used there products and am very pleased with it).

Keep us updated on your thoughts on the intake

Cheers,
Tim Quinn

Short rams on 2.5s - I hear they decrease low-end torque but honestly I didn't really feel any loss. However, I coudl somewhat feel it pulls a bit faster towards the redline. I have the Minnam and the mean growl is real nice when u'r WOT'ing (ie. WOT with short ram only, the noise level is comparable to an exhaust). No whining tho..

i'm using the minnam intake and i agree, its pretty loud at WOT but it is a lil whiney, i'd rather have a honda sounding intake, deeper tone and kicks in a lot earlier (vtec)

so anyways dcgear i think you should give it a shot, if you really dont like it i'm pretty sure someone will buy it off you

for the ppl using the Minnam intake: Do you ever hear the intake without WOT'ing!? i can't notice the sound unless i'm in 3rd @ 4000 rpm!? or maybe my exhaust is drowning the sound

I hear it at about 4500RPM btu once I get into the 5600RPM - redline, geez, sounds like a BOMB. 3rd gear? I get a nice sound on 2nd.

I dont think the intake will really make an aggressive sound unless your WOT'ing

oh no.. not this talk again..

Depends wether you are NA or turbo charged.

WRX's dont need CAI nor short ram. Aftermarket stuff causes your MAF sensor to receive incorrect readings because of the (larger) diameter of the intake pipe. This will in turn cause your car to run lean... and may even cause engine damage.

Some companies such as perrin supposetly made one that is suppose to get around this.. but then again.. minimal gains. It's more a sound mod.


Do your research before you buy stuff.


PS. sti's are another story Vance.

WOT = Wide Open Throttle

What does the whining sound like? I never notice it.

You're suppose to hear it everytime u WOT or do a quick stab on the throttle, both in gear and in neutral. Before and after I've done my exhaust, I can still hear it in every single gear in WOT. I can even hear it when I WOT right after the car starts rolling by slipping the clutch, at which point the sound is pretty deep at the low rpms.

Short rams don't really do much at all. They do give you a little extra power at the top end because you are at speed and actually getting some cold air into the engine bay. When you will really notice toque loss is on a hot day in traffic at low speeds....the car feels very sluggish.

i was happy with my blitz until i had to give it up because my ecutek reflash dosen't like it because the turbulence it creates messes up the MAF readings and causes an excessive lean condition

well there is a reason to why a lot of ECU mod companies want you to take them off before their flash.. they're no good for wrx's.

they're no good for ecu-tuned wrx's, but okay for those with stock programming.

the blitz filter is much more free flowing than a stock airbox and filter. it causes an intial lean condition, and the ecu panics by retarding timing, which results in a loss of power. but the ecu eventually learns and timing is corrected. but when u try to tune for more agressive maps, the a/f readings are all over the place which makes it a bitch to take advantage of... so it's back to the airbox

There have been intake shoot-out tests. Blitz SUS allowed the most CFM in but it was ranked one of the lowest in terms of how clean the air was before entering the turbo.

Some research from Vishnu have tested the stock airbox to be very efficient up to 350 crank HP.

I don't think you will have any problems with it as you are a NA car. Enjoy. ^_^

So what.. the 'Snorkus Removal Mod' is also a hoax that makes the car run lean and the only improvement is sound?

Just wondering about that mod.. I had it on my old WRX, but haven't bothered on the new one since it's so rainy..

No, you wont run lean with that mod. That mod is strictly a sound mod. If you remember reading what i said: aftermarket CAI or Short Ram intakes replace the mounting of the MAF sensor and also have a larger diameter pipe than the stock intake. This either confuses the MAF sensor, or makes the MAF sensor think normal airflow is coming in, when more is actually being sucked in.. causing lots of problems with air/fuel mixture and timing.

Edit: The snokus, besides reducing cabin sound, there is also a small hole at the bottom dip (elbow) of the snorkus, which is probably to let out any water that may have went through the air ram.

Yeah it's an air/water separator, and I think that's why most people prefer to simply plug the ram air hole and remove that other silly hunk of plastic also. The weight savings isn't huge, but at the very least it opens up the area for other projects. Plus, without that piece pulling in water/air from the outside, is there any need for an air/water separator?

I'm running a K&N filter which is supposedly great for holding water out and recovering from getting soaked? Anyone here rally alot and kill thier filters?

I am not going to do the snorkus mod till next summer, just to be on the safe side either way.
