Default OMG!! *** happened?!?!

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?

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.

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.

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

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.

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 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?

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.

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
