140 stock for a rs? I dont think so. A wrx tops out at 140-145. With 60 less hp how can u be within 0-5 mph of the wrx. Just dont make sense to me. And speedos arent accurate at speeds that high anyways. I would say around 120-125 max.

Dude, even if the speedo is off, it's not off by 10-15 mph, maybe like 5mph at the most. Just face it. A stock 2.5RS can run about 140 mph. And I'm sure a stock WRX will run about 150.

sorry, you are wrong... there are many of us who know the car just isn't aerodynamic enough to even approach that mark, much less geared to do it...

i'm just going to do with the testing thats been done from people that have contributed tons to the RS community, and they all say the same things, top speed on a stock rs is between 124-129 depending on elevation, no lower tehn 128 with an intake, and something like 132 with a catback

OK, I did some calculating...

using the stock, 205/55-16, tire size a 5MT RS with a .780 5th gear and 4.11 final drive can conceivably go 144.29 MPH. The 4EAT with stock tires, .694 4th and 4.11 final drive can hit 162.17 MPH.

That being said... the GC8 WRX STi with all of its aero (chin spoiler and ver5 rear wing, rear spats, lower suspension) was independently tested to have a drag coefficient of .36. The 2.5RS' "official" was .35... something's not adding up but we'll use it anyway. Assuming 30 ft^2 frontal area (I have no clue what the RS' frontal area is but I know a vette is 20 ft^2) it will take 141 hp to do 140 mph... that's at the wheels, after all the drivetrain losses. Sorry, try again. A bone stock Impreza 2.5RS would need 126 awhp to do 135 mph... the accepted stock awhp ratings are ~120.

I hit 134mph with my OBD-2 laptop in the car on the way back from Windsor on 80E in Ohio I was at 5500 RPM. I have stock size tires and wheels on. Intake, header and catback or the only real engine mods. The car is lowered on Teins about 1.5". My windows where down and sunroof open.

There is another person that has a pic of his speedo buried and tach at 6100rpm with cams, intake, full exhaust, lowered, and no wing.

I think 140mph is not out of reach.

I have three friends I drive with regularly with Spec-V's, one is stock the other nicely NA modded and if I didn't race them from a dead stop they would walk on me. The QR25 is a torquey motor and has lots of potential, but they already have major torque steer and grip trouble so it will be interesting to see how much the Nismo cams and turbo kits will really help.

GTI 1.8t's have a lot of potential. I have a friend with a 00 GTI with an ECS tuning chip and Brullen turboback and 0-50mph is the only place I stay close to him. He actually barely gets pulled one by my friend's STi.

As for the 1.8t's. They are by far the most under-tuned OEM out there. The 1.8t will make 300 reliable hp on pump gas all day long (damn overengineering krauts ). Chip upgrades alone will put them in WRX territory, UP/turboback will really open them up. I love VW's, used to own a MK2 GTi...wish I would've waited for the 1.8t to show up.

I almost bought a GTI, before I drove and fell in love with my 2.5RS. I was looking hard at the 03 VRS with the 6speed tranny...I still love those cars but my wife hates, HATES them.

When I was car shopping, I heard so many horrible things about VW reliability, and in comparison, consistently good things about Subaru's. I guess that's another part of this equasion...even if some of the newer factory hotrods are faster than our cars, how well will they hold up?

I'd be pretty nervous if I had a Dodge SRT and the odometer was inching towards 120,000. Whereas I know of a 2.5 RS here in Santa Cruz that's got that many miles on it with no major issues AND it's had a big fat turbo kit on it.

I guess it makes sense, if our cars were inspired by rally, that they'd be pretty bombproof.

Funny, that you mention that. The 1g Neons were good handling, mod-friendly, piles of crap.... the new ones look to be better handling, more mod-friendly, well put together pocket rockets. The RS doens't have the best reliability record, nor does the WRX. Some of that is our fault (the enthusiasts) and some of it is SOA not getting the same quality bits and pieces of the world market cars. Subaru does have the better reputation though, and that will last hopefully long enough for SOA to get their service depts in check.

I guess the only way to make you guys beleive is to prove it to you. I will be doing a run tonight on the same road I have mentioned in my previous post. I will take a picture of it and post it here on the fourm. All though I don't think driving and taking pics at the same time is the best idea, but I have to try and get my point across. Later guys.

Our cars' top speeds are not, repeat NOT horsepower limited. They are DRAG limited on the top end. That's why even a 450 hp WRX would get absolutely smoked in a race from 100-1xx by cars like 'vettes and even highly modded Eclipses, SRTs, and others. The Impreza is a brick. So let's stop stressing over the point. You can all do what I posted in that pic above, but it would take HUGE power numbers to go significantly faster.

Not much hope, really:



(From http://www.autospeed.com/cms/article.html?&A=1055&P=5 )

The c-pillar is our undoing, not the brickish front end. The 02-03 WRX is better, but the c-pillar is still not optimal... the 04+ have pretty much taken care of the front end issues... the damn c-pillar is unchanged. The only way to make an Impreza fast is to make LOTS OF POWER and get a different gearset.

My '02 TS wagon would get around 125 stock, got around 130mph downhill. Now I can hit the rev limiter in 5th, but it gets there REAL SLOWLY on a flat road, and I'm on nitrous... Assuming the rev limiter is around 145mph, there's no way a stock rs can get close to that on a flat road. My '02 is even more aerodynamic than the 98-01

Front end yes, but the wagon creates an even larger air pocket (drag) behind the car, plus the GD chassis has an additional 200-300 lbs to haul around.

i heard somewhere that the wagons are more aerodyamic then the sedans. Does anyone know why this is?

I wouldn't be surprised, actually, but have no concrete evidence of it. The shape of the rear hatch appears "smoother" than the coupe/sedan but I'd suspect you'd need the waist spoiler to get better aero.

Hmmm, I know just from research it would take some $$$$$ to speed up the RS but I was clocked by my friend(state trooper) doing 130+ in a secluded area(I had to pull teeth to get him to do this). BTW, it was stock and I did it in Louisiana.

I think the real question here is; Do you really want to go 145+mph?
I know I don't.
What on earth is the point?

i have a bridge to sell you...

seriously though...any VR6 GTI will at LEAST hang with an RS w/out a problem. more power, same weight.

the newer ones (w/ 200 hp) will smoke an RS. they'll run with an RSX-S, and my old RSX-S was MUCH faster than my buddy's modded '01 RS.

it's the same thing. the engine's power overcomes the body's drag up to top speed. at that point (assuming you are not rev-limited), the engine's power equals the amount of power needed to equal the force of drag. usually the top speed will be right around the engine's power peak in 5th or 6th.

Well, the wagons don't have fender flares, which would mean a very slightly smaller frontal area.

I think it has more to do with the lack of a trunk. It should help keep the flow from seperating. It's got a decent rake to it though, so it might not help at all.
