so i took my 02 impreza to the Albuquerque national dragway(5000+ ft). The car is bone stock. I was expecting 17 sec et since my probe gt runs 16's. The thing ran 19.2 at 70 mph. Is this normal? It was slightly rainy so the moisture was in the air but that shouldn't make that much of a difference. I think if i would have tried again i couldve gone into the 18's but still. This isnt normal is it?

auto or manual? What were your 60' times? Gotta give us more info here.

That is a horrible time, dude. I ran a 16.34 in my 2.2L in 95 degree weather.


Mick

I realize that is a horrible time, 60ft was 2.8, 1/8th was 12.33, automatic tranny..... is there something wrong? i have a bumper to bumper warranty... should i take it in and say that i think its not running right and have them check it out?

60ft was 2.8


:lol: Thats the problem...

i can see that 2.8 is a problem, but what is the problem

search: lauching auto

basically autos are slowwwwww so you will get slowwww times

My car was definitely faster than that stock. Try a few more runs and see if you can improve your 60' times. While you're at it, do a run manually upshifting through the gears, and do another run while powerbreaking. Despite the fact that those two feel faster, I think that you can actually do the best in a 4EAT by feathering the gas pedal to control upshifting.

just hold the brake and get the revs up and let off the brake when you see the 2nd yellow light.

just hold the brake and get the revs up and let off the brake when you see the 2nd yellow light. I don't see this a being reasonable with a 2.5 liter 4EAT. Regardless, the car isn't going to be fast. If for some reason you do try this method, don't power brake very long because you're heating the tranny fluid up.

^^only way to launch autos, of course he wasnt exactly specific

you want to hold the brake to the floor rev to like 2k and only for a few seconds at most or else what imprezava says you will break axles and your tranny yada yada

and dont do it frequently

No, this is NOT normal. Your 1/4 mile time isn't normal. Your trap speed isn't normal.

I typed out a LONG post and pushed the wrong button and lost it all. So, I'll be brief with this one.

You need to improve your 60ft time to between 2.3-2.4. It's not great but a healthy stock 2.5 auto should be able to do this with it's low end torque. Let the car cool down for 30-45 minutes after you get to the track. Open the hood and let it cool.

Raise your tire pressure all around to the max setting allowable.

You should be expecting mid-high 16s bone stock. Low 17's on a HOT day. Trap speeds expected should be in the low-mid 80's range, not 70mph. Improving your 60ft time will help some but power is being lost.

If you have friends riding in the car with you while you are dragracing, get them out of there. Unload any unnecessary packages, stuff, weight.

Go to the track with no more than 1/4 of a tank of gas. 1 gallon of gasoline equals 5.8 to 6.5 lbs. That's 70-78lbs of weight you can rid yourself of if you are going on a full tank.

Every bit helps. I'm not going to post again about how to launch. I'm at work. If time permits, I'll post up l8r.

Oh, DO NOT USE HIGH OCTANE GAS. I'm talking about 100+. You will be slower. 89 octane should be fine or even 92 (no more) if you wish to use higher octane. I recommend racing with 89 to help raise your timing advance a bit. I know it does because I've tested it on a Pocketlogger. It helps when it's hot/warm out.

the auto tranny has you limited...trying shifting it manually and see what happens

My manual 1.8 L ran a 17.8... The automatic Toyota Trecel that I actually defeated in that round ran like an 18.1... Its unpossible to run a 19.2 with an RS :eek:

you never put it into 1, then brought up the RPMS till the but byno doesn't feel alot of tourque, clicked it up into 2, brought up the rpms again then shifted into 3, and once you pass the lights, put it in D, coast for a bit, and slow down.....my best time with intake, underdrives, and a Apexn1 was 16.5...and i have .3 less litres than you.

i thought the exact same about the times, should i take it to the dealer? maybe something is wrong with the car, i ask this because we just bought it from the dealer and now im concerned...

by the way, half a tank of gas and everything emptied out of the car

Using the NHRA correction factor for their Stock classes, you're looking somewhere around 0.93 ( http://www.nhra.com/tech_specs/altitude.html ), which means his 19.2 is an altitude-corrected 17.86. Sounds pretty reasonable for a 4EAT with a 2.8 :rolleyes: 60' time.

As for the trap speed, well, that's just plain old sloooow. Are you sure you kept the hammer down all the way through the trap?

should i take it to the dealer? maybe something is wrong with the car...
Ummmm... NO. Imagine how that conversation would go. "Yeah, I just bought this car from you guys, but when I took it to the drag strip and raced it, it just wasn't as fast as I expected it to be." They'll laugh you out of the building.

where is this info from?
car and driver vehicle comparison

but then again i am sure they weren't brake torquing it

note: FWIW a 2002-2004 Auto WRX Wagon runs 16.0, if that gives you an idea of how doggy the Auto really is

with cams and NA work DoctorNick's RS only ran 16.8 @ 82mph

it just feels so much faster on the street. i think with a bettter launch i could been 18 something but stilll

I hope that this does not come out mean.

But.

I have a 2.5 NA Automatic... Its a great car. But _nothing_ about this car seems remotely fast to me. Dragging would be the furthest thing in my mind.

probably the most truth here

the whole point of draggin isnt how fast you are, its how consistant. i was just wondering if this was normal from a rs. i was expecting at least a second quicker

70mph? Is the floor mat under the gas pedal?

I ran a 16.2 in a 5MT '03 RS. TWE Header, TWE Cat Section, Brullen Catback, and Cobb Intake. I don't remember what my 60' time was, but it probably wasn't great.

Elevation was 1250'

Like Pat Olsen said, no don't take it to the dealer. Not yet anyways! Get more practice on the dragstrip and don't get too discouraged. You have to learn your car, even as an auto.

Next time at the strip before you do anything else, please let the engine/tranny cool down for at least 1/2 hour. Hopefully your car has a good tune-up and all. Then go from there with some of the advice some have provided above.

Be sure you are driving through the 1/4 mile still accelerating. With the trap speed you have, I am thinking you let off the gas pedal too quickly.

I'm not going to lie to you, autos are slower than manuals mainly because you can not launch your car at a higher rpm unless you have your torque converter modified. Until then, your 60ft times will suffer. You still shouldn't suffer to the point of 2.8 60fts though. Regardless, keep practicing. Do some bracket racing.

I just ran a 16.418 with a 2.2 60 foot and a trap of 80mph with a stock 04 TS Sedan. My freind in his 03 TS wagon with stage one cams ran a 16.34* :)

Yes, this seems reasonable.

I had to remind myself that the orginal poster was running an NA engine at 5000+ ft with a 2.8 60ft time. All of those things are BAD. Even a good 60ft at that altitude would be way different than sea level. I'm wondering if his probe gt was one of those older modelled turbo ones whose 1/4 mile time wouldn't be as affected by altitude. 5000ft + EEesssshhh! :eek:

yeah good ol 5000 ft, my probe is a 93 gt, N/A 2.5 6 cylinder. The weird thing is my friend has a 99 legacy 2.5 gt mtx and he claims he ran 17.4 stock(the only performance mods he has now is intake and muffler) so i thought the rs would be a tiny bit slower than that but not 19 :confused:
i pulled out my old time slip in the probe
60 ft : 2.439
660 ft : 10.909
E.T : 16.953
MPH : 83.083
on the slip the guy running next to me had a 2.78 60 ft and still ran 17.26 at 83 :confused:

Now im not feeling so bad about my rs running 15.6 (2.1 60 foot)

lol thanks...

With a slightly moded TS 2002 I/H/E I run a 15.854 at 84.5. These car are not made for the 1/4 mile the forth gear is too long and the awd eat the HP. But on the 1/8 of mile they are pretty quick, check this race against my buddy with a Tiburon V6 6speed with a AEM intake.

TIburon TS React. .861 .996
60ft 2.348 2.097
T2 6.777 6.723
1/8 9.904 10.017
MPH 72.596 68.609
1/4 15.217 15.854
MPH 91.068 84.5

At the 1/8 of mile he only a 0.1 of a second on me. Althought he had better race.

Hello Ice Master,

You are hitting fourth gear in the 1/4 mile? :huh:

Also, are you running with an automatic transmission? Saw your 60ft time of 2.0 so I ask.

I think he's saying he can't reach 4th gear in the 1/4, thereby slowing him down.

I hit 4th gear for at least a second, damn short gears are only good for auto-x sucks for everything else IMO

lol short gears are good. He is saying 4th gear is too long.

Sorry guys to have confused you all :confused: :confused:

I have manual transmission. I saw Stijard :

ran a 16.2 in a 5MT '03 RS. TWE Header, TWE Cat Section, Brullen Catback, and Cobb Intake. I don't remember what my 60' time was, but it probably wasn't great.

and I assume that regan was also a 5MT so I was comparing my times.

So those are 5MT times, but the 2.09 60ft is just great you get pull. I love to keep up with car with way more power, but after the second gear they get back at you.

So what I was saying is that after de third gear around 120-125 km/h you change in fourth and you are low in the powerband so you dont get a great trap speed. I think the RS as better ratio than a TS??? anyone on that matter?

By the way my set-up: TS wagon 2002, Brullen headers/Cat/mid/muffler its the quiet system with two resonators, twin tips. I also have a injen CAI that I will remove soon because of the winter coming.

I am quite sure that the gear ratios between the RS and TS are the same, and yes mine is a 5mt. the only "power mod" I have is an under drive Pulley from COBB, it is the light weight that helps me rev a little quicker. I am waiting for my COBB eqaul length header, and exaust as well as a COBB cai.

I just found this and according to this site the, final gear ratio of 5MT TS is 3.900, while the final gear ratio of a RS is 4.111. Althought the difference is probably not that bad since the TS wheels are smaller im diameter.

Thanks. My TS has the RS wheel from factory, It is the same as the US RS so it would probably have all the RS featurs except fogs and spoiler.
