1st trip to track with new 2002 WRX, comments?
I went to Cecil county dragway tonight for the first time with my 2002 WRX. I got the car a few months ago, it came with a cobb catted downpipe, AP with stage 2 ots map, and I added some other things that don't do much like STI catback and GP moto silencer delete. I've been racing for years, my last car was a 66 nova that ran 9.80's on drag radials. I have to admit that is is trickier to drive a 5 speed all wheel drive car than anything I've ever raced. My butt dyno had me thinking the car should run high 13's.
It went- 60' 1.985 330' 5.574 1/8 8.924 1000 11.654 1/4 13.985 mph 97.02 I tried leaving first at 5k slipping the clutch slightly and it bogged, I had to leave at 6k slightly slipping the clutch to get it leave. I was shifting at 6.5k, I tried shifting at 7k and the mph dropped to 95, shifting at 6k it also dropped to 95. I did have one run with a slightly better 60' and 330' but I missed 3rd Besides the 13.98 all the other runs were low 14's. I don't think it has much more in it as it sits now. maybe a 13.7 in better conditions. My driving was fairly decent, I thought. From what I've read it runs pretty much what it should, maybe slightly slow. Feel free to post comments, tell me my driving sucks whatever. My goal for this car someday is high 11's. I know I don't ever want to put a rollbar in it. I want it to be everyting my old nova wasn't, quiet, handle decent, AC, stereo etc. I'm not too thrilled with the ots map, I think it leaves a lot on the table, I'm going to get a tactrix cable soon and try to tune it myself. The last car I tuned for a friend had accell Gen7 DFI and a blower, it ran 8's. So I have a decent understanding of it, just have to get used to enginuity. I think there is a few tenths left in the tuning. Then I think I'll go for 12's with a VF39 or 16G, bigger TMIC, modded injectors and walbro 255. Here's my slip-

good time, better than me on the AP stg 2 map. i just installed a vf39 and im terrified of the track. ithink i'll avoid launching it period track or just the street.

A custom tune and some bolt-ons would make a nice difference. I think you car is running as expected. Hope you had fun!

I went to the track again today. Cecil county dragway again, it was packed. I only got 4 runs.
I got rid of the acessport and the OTS tune. I got a tactrix cable and tuned it myself. I think I'm going in the right direction. I went 13.68 @ 99.1 picked up 3 tenths and 2 mph over the OTS tune. I put the launch control patch in it. It's the best thing I've done to the car so far. Makes it so easy to drive. I watched other wrx's struggle to launch and I just held it to the floor and eased off the clutch and left with no drama. It helped me get a 1.86 60' I think it has more in it, I need to log more and see how much more timing I can put in it. I'm getting kind of high on the injector duty cycle, probably next step is a fuel pump and a little more pressure or mod the injectors. |

Looks like you are making great progress! Just for reference I've seen 13.3~13.5 nearing 100-101mph (give or take- and mod depending) w/pump gas and somewhat stock setups (locally) so you've got a little left in it possibly. I caught your post regarding changing the gearing. I'd like to see that for sure. Keep up the good work!

I'm still really close to stock. The only part I have that really makes a difference is the downpipe and it's catted. |

Thought I'd update this. I found out I still had the cat in the upipe, I thought the car came with an aftermarket up. Oops, I gutted the stocker and put it back on. It also had ngk 7 heat range plugs gapped at 40 I put the stock 6 heat range in gapped at 30. I did a lot more tuning, got the timing all the way up to slight knock and backed it off. I still haven't messed with the fuel maps much it's still real rich. I'm just about maxing out the injectors on duty cycle.
I went to the track again tonight. I ran a [email protected] with a 1.79 60' My goal for now is to run 12's on the stock turbo before I get a bigger turbo. The plan to go 12's is first get a walbro 255 in it asap. Then get access to or buy a wideband O2 sensor and tune the fuel maps. Install a big ebay tmic and y pipe. I don't want to do anything too crazy like an EWG or meth. I know the catted downpipe and sti catback might hurt it a little, but I like it quiet. I might consider a header? I have to see just how bad the ebay ones are. Oh one more thing, the clutch slipped on a few runs, I used to slip it some leaving, now it's making a little more power and if I slipped it, it kept slipping all through 1st. After I let it cool some, it got better. I had to just about drop the clutch to leave without it slipping in 1st gear. I think I'm going to have to get a better clutch soon, it's got a stocker with 109,000 on it as far as I know. I have to find something that holds a little better, but wont kill the trans.

Great progress,... Bugeyes FTW!
If you keep it up you will hit 12's soon,.... If you do look for the >13 second td04 thread and get added to it. |

Thanks, it's been doing so well on the little td04 it's got me thinking. A few bolt ons, some more tuning and a better clutch, I think I can pull off a 12 second run. If I do it I'll see about geting on that list.

Get a stock clutch. Clutches are much cheaper than transmissions! The second your clutch stops slipping at the strip is the second you'll crack a gear and then feel it strip all the teeth off in the next few weeks.
Also, get tuning on the fuel table and you'll see your injector duty cycles drop as you lean out the ratios. Have you switched over to a GM boost solenoid? I highly recommend it... |

^^^one of the locals I was talking about
I agree on both accounts..... the plus side of the organic clutch is it's softer on the tranny...but the down side as the OP found out, once it starts burning it keeps on going...all the way through first - at least that was my experience. Especially since it's pretty "broke in." Even with a stiffer pressure plate I suffered the same thing - but using a different turbo/set-up. Maybe get a clutch disk that is composite/ceramic on one side and organic on the other so there is still a little give. Last edited by TyranosaurusWRX; 05-01-2008 at 04:39 PM. Reason: afterthought |

I figure the duty cycle should drop some with tuning the fuel maps. Under high load I'm at 10.2 afr now. I hit around 94% duty in 1-3 and in 4th around 98%. Leaning it out should hopefully get it down to 90% or less. I know I can mod the injectors for free, but that's a little overkill at this point. The 255 pump might help slightly too. The GM boost solenoid is nice. I might do it eventually. I've got the stock one tuned in ok so far. I can make 13 psi against the launch control, 18 as soon as I let off the clutch tapering to 14. I want to try to taper it to 16 but it doesn't seem to be able to hit that much boost even with a lot of duty cycle. Maybe with the GM solenoid it could? |

That's exactly what it did. With less power I could slip it a little on launch, with a better tune if I slipped it, it kept slipping all the way through first til I shifted. I let it sit and cool for about an hour and then dropped it harder and it held and went a 1.78-1.79 60' Not dumping it, but not letting it slip, somewhere in between worked ok. Not a sidestep, but just coming off the pedal real quick.

Yeah, it's my opinion that there's a very small window where you can pull that off. It works perfect when you do but not so easy.

My stock slipped a good bit when I 1st started taking it to the track,...
Then it magically got "worn in" to the type of abuse it was getting |
