Unhappy loss of power within 3 weeks of purchase

I just bought a 2002 WRX I love it, when I first got it it kicked a$$, but after about 3 weeks or 675 miles I noticed a loss of power. It wasn't slowly either. One night I pull up to a light, a POS cicvic beside me, figured "No Prob." I went to drop the clutch (yeah I know not good) anyway I got nervous and let off the accelerator too. The civic jumped off the line but was no problem as soon as turbo kicked In I was up to him in no time. I shift to second... It's like we had the same car I was neck to neck with him. Something was wrong! I went to the back of my neighborhood and noticed I didn't feel the kick I felt anymore from the turbo.

Whats wrong guys help me out. If there is anything wrong.

I went to the dealership and the guy said it was fine.

Did anyone else just kinda stop feeling that little kick they used to get when the turbo kicked in at about 3000??

Thanx

yeah, whenever it's humid and/or warm outside the car feels a little sluggish. This is normal though. Your perception of the acceleration diminishes.

I'm confused.. Are you pushing the car hard before your 1000 miles are up?

maybe you have a boost leak?

It takes time for the turbo to spool up buddy, dunno if thats what youre reffering to. I know the ones Ive driven it takes about 3.5k-4k rpms to get full boost.

Gotta agree w/ Nick on this one. Not saying that there's not something wrong with your car, but I bet if you did some timed runs your car is actually getting a little faster as you break it in.

That's the problem with the butt dyno. It gets jaded after a while .

Bro, you need NAAAAAAAWWWWWSSSSSSS man

Hey, I highly recommend you take it easy on that poor engine of yours. There's a thing called a "1000 mile break in period" where the piston rings are getting seated properly and without that break in period you could possibly have a problem with oil getting into your fuel mixture or fuel into your oil, and burning that oil up. That's why you see black smoke coming out of engines, it's the oil being burned in the fuel. Not good for engine, and not good for your oil level

Also, that oil you have in the car has metal shavings (microscopic ones) in it, so it's not really supposed to be pushed.

Anyway, it's your car, so do as you please. (your welcome, cuz that's a one time offer )

I was just complaining about a loss of performance the other night at the meet... I'm chalking it up to weather though, because its been back to its old self now that the weather has broke a bit...

about you and a civic.. either you shifted to 2nd really early.. or he had NAS.

I noticed a loss of power a couple nights ago after my car threw a CEL. It cleared the next day by itself but seemd much slower. I resest the ECU and it feels like its old self. I don't know if this might help but it worked for me.

I definitely agree with nt5k and bluedemon, and that the weather does play a huge factor. But also make sure your ac is off when running your car hard, that takes away power too.

i was in front of a 96 cobra off a stoplight with my ac on.... heh not that 96 cobras are fast, that was kind of a bad year i believe.


silverscooby - watch that MBC.... if it gets cold the boost will run higher.. on a REAL cold night (like winter).. if your boost already >16.... it could spike >19 and throw a cel.

I never threw one though.

Default AC

actually, our car has a built in capability that when you stomp on the throttle, the AC is actually cut. Not the air, as if you try this you will notice the air still comes out strong, the computer just cuts the compressor. So feel free to ride around and stomp on it. Although, I must admit, I feel a bit of power lag when it is on. Can't be perfect, I suppose.

Edit: Don't quote me on the compressor bit, as I'm just adapting my basic knowledge to what I think the computer MUST cut.

That is true. It's in the manual I believe. But only at WOT will the compressor disengage. So the hesitation is still there if you ease into the throttle. It's always good to turn it off for a race but if you don't and go WOT, it will shut off automatically.

FYI also, if you have your front window defogger on it turns the AC compressor on automagically. the little light doesn't come on but if you watch your tach it runs just like then the AC is on.
