Lately, I was thinking of different ways to modify my airbox to ram air in from the hood scoop to force a little more cold air into the engine. There should be a little cup to catch rain water before it reaches the throttle body. I had the urge to look up 'ram air' and I came upon the E-ram Charger. I'm thinking this would be a nice simple mod to keep me going until I pay off my car, then save for a supercharger/turbo. A one pound of boost to increase about 5-10% hp to wheels for $299.00. Wait! This works just as well on Turbo's! I'm getting this E-ram for sure, but I just don't know how much whp the RS can achieve. Does anyone have this in their RS or know about it on the RS? Your help greatly appreciated.

I think there is someone over on I-Club who has one of those on his RS. You could go over there and do a search for E-Ram, should show up. It does sound intriging, I have to admit.

Didn't the person who installed this "E-ram" thing finally gave up on it? He said that it didn't really give him the boost in ponies that he expected. So supposedly he uninstalled it and is going to a different route in getting more ponies.

They do say that it should improve the 1/4 mile time by taking off .1-.2 seconds. It doesn't sound too impressive, but would it still be a good add on?

Subarumantoo... you mentioned the turbodyne charger on your site, also. Is it similar to the E-ram (electric powered), but has the 3 lbs of boost? It would go for 5x more than the E-ram on price though... Is it out yet? I've never heard of any of these until I did the research on it on your site. Lots of info on your site, dude!

Is there an Aerocharger application for the 2.5 RS? :confused: Their site doesn't have any Subaru options...

Yes, I emailed them and Corky Bell (you know who he is, right?) replied with the model. I have the email somewhere at home - I'll see if I can find it.

The Aerocharger is just a turbocharger with a few modifications. Im doing a research project on the technology right now.

The major difference is that lubrication of the bearing is done using its own oil reservoir (oil similar to the type used in aircraft jet-turbine engines). This means that you don't need to tap the block/oilpan for oil feed/return lines, nor do you need to run coolant lines into it. It is completely self contained which makes it easy to install.

The other major difference are the models with VATN. The turbine nozzles can rotate. This makes the unit effective for INCREDIBLY fast spoolup time, as well as it is used for boost regulation (no wastegate required. Just rotate the nozzles to control the amount of boost).

Drawbacks are is service life is somewhat shorter than a traditional watercooled turbo, and its EXPENSIVE.

Ive got another 15 pages or so talking about the Aerocharger if anyones interested.

Um, yeah, I would have to argue that it's not *just* a turbocharger with a few mods. ;) The performance is pretty much kick ass, especially considering a much faster spool-up.

Please, do post some details. I've read everything I want to know about it, and it's good to go as far as I am concerned, but more info is alway good. :D

The fundamental idea is that it is a standard turbocharger with a few modifications (those few that I list). Another difference too is how the turbine/compressor housings are attached. A metal ring with "teeth" around it clamp onto either side to limit the heat transfered from the turbine housing to the compressor.

Id honestly consider things fully about it "being good to go". Like I mentioned, its EXPENSIVE, and less reliable. You might also try talking to Andrew Nam (AMR - of former Minnam fame). He was trying to produce a TT setup for the RS using Aerochargers.
