Default My 1st Time Dragging My '04 WRX Stage 2


I know my mods aren't the greatest or smart for that matter.
Catless HKS flat plate with stock catback, but OTS tune for catted downpipe and TBE on 91. Using California 91 but not tuned for it.

Tell me what you guys think.

I also have a concern about my 60ft of 2.2
I tried to feather the clutch with WOT to 5500rpm but couldn't break 2.2

Should I go to 6000 next time?

Also, what is the elevation at Sacramento?

6000rpm isn't going to help you much but prob burn up your clutch. Id stick to 5500rpm but pump the throttle to get some boost going, not just hold it at that rpm.

I believe its 100' above sea level.

Here is something to compare it to. i had an 02 WRX that had TBE and intake with MBC set to about 18psi running 100 octane and an act clutch combo. I had a 1.8 60 foot i believe but the ET was 13.3 and trapped 105mph. Annoyed the hell out of a turbo'd civic bubble butt hatch bc i was beating him so bad off the line he couldnt make up the diff he was trapping 116...

I held it at 5000, then WOT to 5500. Is that not the best way?
100' above sea level, what would be the corrected time for 14.8?

That's a real good time. It's weird how in California we have 100 oct but not 93 oct

best way to launch is i found was to hold it at a certain rpm like 5k and as you slip the clutch gas it and work the clutch so you dont bog it. just play with it to see what drops your 60 ft times the best

The best launch I experienced, involved riding the clutch with wide open throttle for quite a while

Can someone tell me what I'm doing wrong and why my times are so bad?

What tires are you using and how old are they? It could be a bad tune, do you have any times from before you added those mods?

I had brand new Nankang Radials. Tune is Cobb OTS (48 states)

I did a run at stock and was getting 16's and 17's *face palm* hate to admit it. The launches were bad during this time, but I can't imagine bad enough to put me in 17's. I get 15's with a Honda and bad launch.

Get motor mounts and a twin plate clutch...then try launching with R-Comps!

Tires can play a part in times, depending on how much grip is left in them. What are your shift points in RPM from gear to gear (2nd to 3rd, 3rd to 4th)? How quick do you shift? Are you flat foot shifting? Other than driving, it would seem like there would have to be an issue with tune or parts to have those times. Have you looked at your PSI when at full boost?

Practice makes perfect, at least you got out there! Congrats on your first run, pretty good rush isnt it?

Still on the TD04 I assume? Do you have a boost gauge?

Learning to launch an AWD car takes a bit of practice but it really is not that hard. The topic has been covered roughtly twentytwobillionmillion times so feel free to search but because I've got some time before I'm off of work I'll break down the way I launch with a small turbo-

First off don't feel like you need to leave on green. Leave when you are ready.

I've always had pretty good success launching about 1k-1.5k rpm above where peak torque/boost is made. An EJ205 with a catless TBE and the factory TD04 should produce substantial boost by 3k rpm. So I'd focus on launching between 4-4.5k rpm range.

Large frame turbos need high rpm and some sort of launch control helps greatly to generate boost on the line. Your TD04 does not. You can generate boost quite easily just by using your right foot.

-Stage the vehicle (first set of yellow lights), the other guy should stage next. This is good racing etiquette and should be practice every time it's your turn to race

-Start to BLIP the throttle as quickly as your right foot can move, bouncing the tach between 4k-4.5k rpm. If you have a boost guage, you should blip until you can't get the needle any further. If you don't have one, I'd blip for about 4-5 seconds.

-Next you want to start to bring the clutch out until you feel it JUST starting to grab then push it back a millimeter (so not to burn it while blipping and also not to final stage (second set of yellow lights)). This does a couple things, 1) lessens the drivetrain shock for when you finally release the pedal and hit the gas and 2) you have a better idea of the grab point and can more accurately slip the clutch minimizing your chance to bog the launch or burn the clutch.

-Now you've got your boost ready, your clutch is ready to be slipped and you're ready for take off. Start to ease it little by little until you see the second stage lights turn on which will active the tree. I'll say it again, don't worry about leaving right at the green. When you feel it is right, go ahead and QUICKLY slip the clutch (DO NOT SIDE STEP IT) while going WOT. If you did it correctly, it should leave smoothly without bog and no burned clutch smell. Second gear comes up VERY quickly so be ready to shift!

OP, because you are just learning, remember this- if you're going to error, error on the cheaper side. Meaning it's better to slip it slightly slow and put the abuse on the clutch than it is to slip it slightly fast and shock the transmission which can certainly cause a broken gear.

After you get better at getting off the line, you need to focus on shifting. Once you learn how to shift, start focusing on shift points (rpm). When all of this comes together it's a fantastic feeling and you should be putting up some pretty clean passes. From here you can start replacing parts to go faster and because you have become consistant in your driving you can guage how much of an improvment each part adds.

I've said this in a previous post, and I'll mention it here again. There is NO reason to race your car when you know it is not operating at 100%. Reasons being your going to put up crap times and be disappointed while also possibly causing damage to your vehicle. Also, if the car is not driving like it should be it makes it very difficult to review your timeslip and know where improvments are needed in driving or where the car is having mechanical problems.

Hope this helps and sorry for the long post.

Motor and trans mounts will help sure, but not really needed. Don't think you're going to go busting mounts with a TD04. Twin disc clutch will be total over kill and so are the R-Comps for that matter. Once you get your technique dialed in and you can produce consitant results, then you can start looking towards stickier tires, more power, etc...

I cut consistant 1.7 60ft's using all season Bridgestone Potenza's and a few in the 1.6's.
