Help me analyze my two time slips(possible problem)...

[QuikSilver SRT-4]

Well here are my best time from my first time to the track with the following mods: Stage 1, Stage 2 WGA (18/15) on stock vac. lines, CAI, MM Inserts, Mopar BOV, Borla CatBack, MSD wires, NGK Plugs, stock tires(22psi).
Track Temp:89*
Humidity: 72%
Best Run #1
60'---2.463
300'--6.326
1/8---9.474
MPH--80.66
1000'-12.095
1/4---14.359
MPH--100.52

And here is the first and only run I got in at my most recent trip to the track with all the same mods, holding about 13psi(cooler weather), except I added a NeedsWings 3" w/cutout that I ran opened and BFG Drag Radials(12psi)
Track Temp:58*
Humidity: unsure
Best Run #1
60'---2.107
300'--5.922
1/8---9.015
MPH--80.88
1000'-11.693
1/4---13.949
MPH--100.34

1.)I obviously was pretty disappointed in my times, but more so in my trap speed. Why was it LOWER with with the new mods and cooler weather?Shouldnt it be higher? Too little air pressure in the tires?
2.) From the slips, does it appear as if my car is pulling timing up top? MAP Clamp help?
3.)Any and all suggestions you have to help me get this car to at least mid 13's will be greatly appreciated.

Boost leaks? definitely test for boost leaks.

Does it appear as if the car is pulling timing from the slips?

[peteblksrt4]

no the major difference is the 60ft. w/ the drag radials u should be under 2.0 i get a 2.15 (w/ mopar motor mount inserts) on crappy michelin tires that is the BIG difference between the times b/c of that 60ft i

[Annihilator]

60' does make a difference, however you should definitely be trapping higher than that, unless you're running at a track that is at a high altitude.

Sounds like you have boost leaks to be honest, if you could tighten down your clamps right before racing and then report back, that would help to narrow it down some. And you might not be pulling timing up top, more than likely you're just running rich, since IIRC, the stage kits make the cars run extremely rich. Got a wideband?

[peteblksrt4]

a really good tune will help a lot too

It'd be extremely hard to tell if your car is pulling timing by a timeslip. A dyno-sheet would be a better gauge but if you don't have a clamp, fuel controller, or W/I you can rest assured you are pulling timing. But I believe with some more practice and a better launch you will be able to nail down some better 60ft times, thus resulting in better ET's.

P.S. Ditch the S2 WGA & get yourself an AGP or Kinetic WGA. -Run the vac line from the WGA to the back of the turbo, zip-tie & you're good.

You could have a boost leak. I had a cut vacuum line in my car and gained 4 mph after fixing it. Powershifting will also help times, I don't have a comparison for my car, but I consistently run .3-.4 quicker with the same 60's than my bro who doesn't powershift his civic si. I ran a 13.05 at 101 with only a 1.90 60' so you have the potential for the same if you cut a better 60' and shift quicker.

Absolutely! I run 18lbs in the drag BFGs also and have some 1.9 60ft times and 8.3 to 8.4 1/8 mile times with 20 lbs spike to 16.

Hey I followed the link you posted in my thread. Since I don't even know what's wrong with mine, it's hard for me to guess what's happening to yours. It doesn't look like timing is being pulled up top though. You're gaining about 20mph from the 1/8 to the 1/4. That is about what we should gain. Still, your speeds look too low as well. If it is pulling timing, it isn't just up top, it's across the board. I personally think it looks more like a boost leak. which is why your speeds are lower but consistent all the way across.

Hey man:

For a long period I use to run the same times you did until I figure the tune. I got to 13.4@109.58 on street tires spinning thru first and 3/4 of second. I bought a pair of slicks but won't get to use till next season. I had 2.3 sec 60' on street tires so as you can see I should of easily seen 12.8-12.9. For every tenth I pull off my 60' I should see 2 tenth reduction in the 1/4 et. My mod are basically the same except stage 0 and a large FMIC to keep knock in check. So this is what I did:

1. Do a leak test make sure all is tight
2. I adjusted my wastegate to spike 20 and hold 15 at redline (Max for a stock setup). Keep tightning your wastegate to get the above results (By the way I bought a map clamp and return line to be installed in the next couple of weeks.I will then tune with my wide band for 12.0. I should be able to spike 23 and hold?? time will tell. I will start base pressure on my return line at 50PSI hooked to the back of turbo)
3. Very important this move gained me 2/10 of a second-gap down to .032
4. Run 94 octane to stop any chances of the knock sensor pulling timing. If it does you will run flat, and your times will look like the ones you posted.
5. I wired my AGP wastegate exactly as per the agp instruction totally bypassing the stock electronic control and made my own bleed with a .045 hole as per instructions. Spike 20 holding 15 redline. By the way when I was spiking 18 I held about 13 at redline. With proper fuel 94 octane you are leaving power on the table. It made a big difference for me spiking 20/15.Once again don't forget to gap down (very very important...). I also pulled my red line going to the tip which should not be necessary on stage 1. See your AGP install instructions

My Mods

Stg 0
AGP wastegate bypassing stock lines so the PCM can't screw with me
Solid MM
Large Perrin FMIC
Perrin Fuel rail
3" dump exhaust
3" JMB CAI
Gapped .032
94 Octane fuel

And that is it for the possible 12.8 run on slicks (to be confirmed next season). As you see it doesn't take a lot its all in the tune... With my slicks,map clamp and return line I am hoping low 12's I am confident.
