Ummm...well....if you really think about it, labelling one part for a certain amount of hp makes no sense. It's the combination of parts you use that will make more power. An intake and stock exhaust can make as much hp as a full exhaust and stock intake. To me, the beauty of Subaru is that you get more hp per mod compared to a honda, nissan or toyota. Forget total numbers and think of how much power and torque this car makes from just bolt ons. Full exhaust, intake and fuel mods on a Honda 1.6 can net 10-15hp. We get 15hp from an intake alone!

200hp for an n/a 4 cylinder was a number invented by an old SCC article trying to detail an all motor buildup on dinky honda 1.6's and 1.8's. Power from cheap bolt ons is one thing, and you'll soon find the bug has bitten you. Subarus get more power from cheap bolt ons, if that's your question. Don't worry about spending 2 grand and only getting 15 extra hp like other popular imports. If you get past the cheap bolt ons and tkae engine apart, and retune the ecu, you'll find gobs of power you didn't think existed....and broken parts you didn't know could break, and low gas mileage you didn't think was possible.

You can drive it sane...as long as you can control the urge not to.
Personally, dropping the hammer in 4th gear on the interstate and leaving cars at 60mph like they're sitting still is far too tempting. I'm glad I have a beater....potential for much less trouble.

I mentioned fuel cleaner because that's what it does, clean the fuel and the injectors. My RS is now standing with 44000+ miles already, so I try to do as much research as I can on the cheap ways to maintain/gain hp. I'm sure it also depends on what kind of fuel cleaner you use (FYI, I use Amsoil's fuel cleaner). Never anything but synthetic oil into the engine (I mean Zmax, Prolong, etc.).
I agree with Boxer on the hp per mod on other cars vs the RS. In some import magazines, mods only provide 1-3 hp for exhaust and the same for the intake. Oh well. Here's the dyno sheet for the MRT system:

Streetman,

Come on up to Anderson on Saturday. I'm sure you could talk several of us into giving you rides. I've already offered (see earlier post...BTW I am known as A2CPC on the other board). Dale (dbrier) and Ed (edkwon) are going also. There were 6 or 7 Imprezas at the last solo.

If you are interested, we are meeting at the McDonalds in Fishers(96th and 69) around 8 am and will probably leave 8:15-8:30.

Drive yourself up and you can leave when your bored. Hope to see you.

Chris C.

I'd really like to get up there for more than just the autocross-tell you more on that in another post. I might even race the Acura. It's going to be sold to someone in the next couple days. Already have had two offers that came close. Figure I could rag it once more before someone else gets it. Just need a helmet and a car that has good brakes/tires for the most part right?

On the 200 HP note, I'm still saying that it can be done. My original idea on i-club:

Here's what we need:

FULL exhaust
CAI
Pullies
Something to give it some extra go-go juice, and advance.
Mad props

That should get us over 200, right?

The SCC article is in the March 2000. They used Minnam intake, Stromung (catback, I think), and AFC. Without the AFC they saw a loss of power on a couple setups.

To expand on my original idea, I'm going to say the Bruellen Headers, along with the rest of their exhaust system is the most proven way to go for a full system. Includes high flow cat. And yes, I know your local muffler shop can build something cheaper. I'll pay for the performance gaurentee, thank you. CAI from anywhere. Ganzflow seems to work without low end loss. Good enough, and a bargain. Pullies as light as you can stand.

And my "Something to give it some extra go-go juice, and advance" coment was some sort of AFC. Is there something between a S-AFC and a TEC-II. You figure by now someone has made something laptop programable, without the complexity needed for a turbo. READ-CHEAP!

Well, I could go on. Just some things to thing on. If you guys want to get some really good insight on this, the second instalment of it is at http://www.i-club.com/forums/showthread.php?s=&threadid=107544

Real quick, here's Cobb's Stage 2 description-
"Included with our Stage 2 Power Package is our acclaimed Cold Air Intake System, a full Stainless Steel exhaust system consisting of headers, high flow catalytic converter and our Stainless Steel Performance Cat-Back Exhaust System. Also included is a Power Pulley kit complete with new accessory belts and a Cleaning and Oil Kit that will allow you to easily service the intake filter for the life of your vehicle."
At one time they claimed a 20% increase for it. No longer making that claim. Hmmmmm...makes me think.

In the ad for Centerline wheels in import magazines, if I can remember correctly, their 17 in rims weighs 15 lbs each while the same rim in size 16 weighs 13.5 lbs. They said on the ad that it will give the Honda Accord roughly 5-6 extra hp. Now, considering the Accord is driven with only two wheels, would a change in lighter rims double that hp of a front/rear WD? Let's say yes. That's 10 ponies there, thank you.

I would say the 'E-ram' if it wasn't considered forced induction, but it is so I'll stop there.

 

[Streetman]

'E-ram' ?

I'm not familiar. anyone?

 

[Cone Eater]

Streetman,

I think it has something to do with an high output electric fan. Are you going to meet up with us at McDonalds in the morning or in Anderson? Yes all you need is a car that will pass inspection and a helmet...Hope to see you there!

 

[Streetman]

I remeber the e-ram now. Did that thing ever get proven? I remeber, like most other mods (torque chip), people taking sides on whether it worked or not, and attempted to prove their position with a lot of arguing and arm waving. Did anyone ever actually something more accurate than the obligatory butt dyno?

Cone Eater,
Got a helmet, and the car is in good shape. I've got people calling on it though, and one supposedly coming out tomorrow. I'd hate to be up in Anderson having fun, and not get rid of the POS. I might go...If I'm still up at 8!

 

[Cone Eater]

You are going to stay up all night?...Shame on you

E-Ram = big scam.

It's a little fan blade from a model airplane that cannot provide enough power to do any good.

 

[kickin_81]

I used to think the E-ram would be a good 10 hp before, but the customers say it's not worth the 300 bones. FWIW, it provides 1 psi of boost using the alternator to power it. Good on low end, but bad on top end because the engine needs a certain amount of air for a certain rpm.

 

[Streetman]

Hey, I'm just sitting here (at 3AM) listening to a new, and amazing breakthrough in air mixture technology. It's called the Tornado. It's got a patented air fin design that spins the air! You'll increase performance, and improve gas milage. How much? By 24% more miles to the gallon, and 5-20 HP! NOt possible? It's a "spinning vortex of air!" I know it will work because I saw an asian guy in a lab coat spin water from one bottle into the other. That proves it.

It works just like a "fuel efficient turbine jet engine". And you know how fuel efficient them is. They even interviewed an elderly woman whose son got a speeding ticket in his little 3 cylinder car because he recently installed the tornado, and his car was so fast.

PLUS, it's fully gaurenteed by the Tornado Corporation. We all know they're not lightweights in the engine intake spinning, foil, fin, pinwheel looking devices market.

"Hey, if you want me to take a shit in a box, and mark it gaurenteed, I've got spare time."

 

[imprezadan]

A product eerily similar tp the "e-ram" was on sale in the European market (the "turbo-zet") until it was proven to be a total scam. The company was then forced to stop selling it there.

 

[FuJi K]

does nitrous count as a bolt on? if so, it wins!! if not.........then what the others said.........:sunny:

 

[DoorKnob]

I'm surprised that no one mentioned this one.

You could get yourself an itc put in some premium gas and advance the ignition timing a few degrees. It'll net you a few extra hp without any losses.

 

[kickin_81]

ITC??? Pics, please.

 

[Streetman]

Knob-

Depending on how the car is tuned in the first place, you might or might not see any difference from advancing it. In fact, advancing will almost always take a little from the low end power. I'd bet with the Impreza's low end grunt, you could screw yourself out of low end, but get a higher overall output up top. Anyone done this, without the variable of the turbo?

 

[hakujin]

kind of an impractical thought, but has anyone considered getting rid of the a/c and power steering? getting rid of just the a/c should free up a couple extra ponies (if you don't need it)

Well, I was always told that it was all gain.

But in anycase, that's the beauty of an itc. You can adjust it so you leave the low rpm timing map unchanged and only advance at higher rpms. So, either way, all gain right?

So what is an ITC? I am assuming that the t=timing and the c=control. I am intrigued and would like to know who makes one and what, exactly, it is.
