Default Dissapointing Stage 2 1/4 mile -help

I have the TXS Stage 2 kit along with Samco IC hoses and a GFB BOV. My best time was as follows:
60 ft. - 1.878
1/8 mi. - 8.841 @78 mph
1/4 mi. - 13.82 @97 mph

This is what I considered a flawless run, but am dissapointed with the times; I was expecting low 13's. Shifts were smooth and performed at 7000 rpm, boost developed pretty much as indicated in the Stage 2 instruction booklet...is something wrong or was I just expecting too much.

Thanks in advance for any comments.

Hilarious reply Yep, the car is so slow that I was able to post part of the message as I was going down the track; pretty sad.

I just edited the post to correct it.

02trex: which "version" of the stage 2 do you have?
Is is the 91 octane one? Also, what boost level are you running and how (MBC or what).

I'm running the 93 octane program with the ABC set to 17.5 psi max. Originally it was set at the 16.5 max as received out of the box; while the boost increase showed up on my boost gauge, there was no difference in 1/4 mile times.

There are 2 things that look like they could be wrong.

1. you have the samco hoses...
Standard stage 2 does not have this setup. From all accounts the hoses make quite a bit of difference in the ammount of air that is getting into your motor. Your likly in a situation where because of the hoses you have a bit of a lean spot, and need to have mark add a bit of fuel to compensate so that the ECU does not pull timing.

2. You had your boost set at 16.5psi and then cranked it to 17.5psi and saw NO difference in the 1/4 mile. This is consistant with an ECU that is pulling timing for whatever reason. It could be almost anything, but you need to give Mark a call as he will have a pretty good idea of what to do.

was this at MIR yersterday? My friend ran his white wagon with the stage 2 and his best was a 14.4 , don't recall the mph, but the 60 ft. time was 2.0? even with that high 60 ft. time a 14.4 seems awfully high. My guess would be nathan's 2) answer, timing was prolly being pulled making your car slooow.

Yes, I was at MIR. My other runs consisted of 2.00 60 ft. times and 14.22 1/4 mile times.

I talked to Phil from TXS as he was there last night and though he seemed surprised, he suggested I up the boost for the track; but again, this did not help. I guess I will try to contact Mark on Monday.

Bighurt1, thanks for the tip; Phil also mentioned that I should shift before redline to stay in a higher power band. I did not get to try that as the place was packed and the lanes closed before I could make another run. Next time.

thats not so far off, but with that much boost I Would expect mid 13s.

you could launch better, shift quicker Im sure.

be sure to let 3rd gear go as close to redline as possible.
4th gear is over driven.

wind might have been in your face, its getting warmer, times will slow down.

etc etc etc


did you show up with a full tank of gas?

jmott, I'll agree with you regarding the launch as I was only able to go below 2 seconds for the 60 ft. on one occasion, but the 1.87 felt pretty good. As for shifting, I'm comfotable with that.

Regarding third to fourth shift, here's what happened: on one run I thought I was close enough to the line to stay in third, but I hit fuel cut at 7200 and had to shift from there; on the next run I made a shift to fourth at 7000 and crossed the line; result: exact same time. Both runs consisted of 2.00 sixty ft. times.

Also, it was very cold last night and I ran on 3/4 tank of gas.

First I would not be that disappointed. You failed to list how much boost your running. My stage 2 setup was only making 14psi of boost through the Unichip? I don't use the ABC, I use turboXS HPMBC. It gives alot more boost in 1st gear and also holds max boost longer than the ABC setup.

I'll will bet you anything the guys that are running low 13s like myself are using a MBC setup with their unichip. It just gives you alot more power off the line.

At the track for sure I would run a MBC. Set it to 16.5 -17psi boost. You should be able to pull off some low to mid 13s for sure.
Also shift at redline. I usually shift into 2nd, 3rd and 4th gear at close to the fuel cut off of 7200 rpms.

yeah its tough on the 3-4 shift. let it go too long and you hit fuel cut, do it too soon and go slower. gotta get it just right.

1.87 isnt a bad 60ft by any means, but you can prolly do a teeny bit better.

SGOSWRX, I had the ABC set to 17.5 max; it would hit that for a split second and then fall to around 14 +; normal, I believe. Also, my theory on the performance was based on your time (13.3), but I had not originally noted that you were using the HPMBC as oppsed to the ABC. Still, I would have thought that the extra pound of boost would have made some difference (17.5 with one full turn on the ABC as opposed to 16.5 out of the box).

Thanks to all for your responses.

For comparison:

My only power mods are the JoeP MBC and 3" BPM MKiii exhaust.

I just ran a 13.77@98.24 mph at Atco on Thursday night. If I could learn how to launch the car and get a better 60' time (track was SO sticky, best I could do was a 1.84), the car would run close to a 13.5.

This was at ~16.5psi, and I was datalogging my runs. My timing was always 18-24degrees the whole run, and the o2 was reading .96 -.98V. EGTs NEVER broke 800C, so the car is running very rich.

Forcefed4 , Driver skill really plays a big part with these WRX's. Your 1.84 is about what I usually run. Last night I ran a 1.81 and an 1.83 60' times. I only made 2 runs at my local 1/8 mile. Both my runs were 8.55 @ 80mph in the 1/8 mile. A good .15 off my best 1/8 mile time but it was 80 degrees with high humidity. Down here in S. Florida I'll have to wait untill next winter for cool air.

The reason I tell you this is because a few weeks ago when I was running 13.3 and 13.4s in the 1/4 mile and there was another guy in a WRX at the track and he could only run 14.6. He had a JoeP MBC, K&N filter, and cat back exhaust for mods. I was a bit suprized he was running so slow. You are running a full second faster than he is and I would bet its because you know how to drive really well.

It reminds me of Evan Smith. He can run a good .3-.5 of a second faster than anyone else in a mustang or a z28. He can take a stock z28 and run 12.90s. Then he gives the car back to the owner and the owner can only run 13.6+ in the 1/4 mile. He does it all the time.
I bet there are a lot of guys running MBC, or stage 1 or stage 2 setups, or Shiv's stage 0 that are running high 13s and even 14s that just don't come forward because they are embarrassed or what ever. I know of some guys that run mid 15s in stock WRX's while others run low 14s. Some guy was in here a few weeks ago saying he knew someone who ran mid 13s with just a down pipe and a cold air kit.

There are just so many variables that effect 1/4 mile times. Its hard to blame the car or the modifications. When guys run mid 15s in stock WRX's that really shows what I'm talking about.

Mid 15's?

I run 15.0@90 with only weightloss and an intake, and that's an RS.

My bro ran a 13.5@100 with K&N and MBC...

He's not wrong in being dissapointed with his times...

I would think your car should be faster too.

No offense, but that's why I stay away from stages.

yep, theres two guys in my town who had the same mods as me back when I was running 13.5 (full exauhst, unichip type cars)

both of them were running 14s at the track.
while another friend had just full exauhst, stock boost, hit a 13.9

quick shifts and a good launch are key.

as are tricks like taking out the spare and showing up with the gas tank near E

No offense, but that's why I stay away from stages.
First off, I need to address the issuse of my car should be faster too. If you knew anything about WRX's you would know that my 13.3 is a extremely good time for the mods I have.(unichip, turbo back exhaust, mbc) I have yet to talk to anyone who has run faster than me with my same mods. Doug ran 13.2 with Shiv's stage 0 and thats the fastest I've seen with those mods.(up pipe,unichip,pulleys, mbc) In 2 weeks, I get my up pipe put on and I'm hoping to run 13 flat or break into the 12.9s. I think it is a long shot but possible given I run consistant 13.3s now. I have yet to hear of anyone running 12s with the stock turbo and those mods. So I don't understand how you can say my car should be faster than it is.

2nd poing - that you missed in the above post. You can't compare a car running a Unichip set up with a MBC set up. The Unichip has a safty margin built into it that a MBC doesn' have. The Unichip doesn' give you very much boost in 1st gear and also tappers the boost in the other gears. The MBC gives you alot more boost in 1st gear and holds max boost much longer in other gears- thus much better 1/4 mile times ( not as safe on the car but much faster)

I dropped from (8.73 - 8.80) sec 1/8 mile times on average to (8.40- 8.60) sec 1/8 mile times on average just by switching to a MBC. It makes a big difference.

Also I would be interesting to know what boost pressure your bud was using in his 13.5 @100mph run with just a MBC. Plenty of guys have run mid 13s with MBC but the 100mph trap speed is real fast. It would indicate 275 +hp

Default question for nmyeti

Nathan, thanks for your earlier reply to my post. You suggested that the ECU may be pulling the timing because it senses a lean condition due to the IC hoses. Would this timing reduction, in effect, make the car run rich? I have noticed that since I put the hoses in, the muffler tips are sooty, as much if not moreso than stock; yet when I had the TXS Stage 1 and stock IC hoses, the sooty muffler tips were gone.

Thanks in advance.
