    I am happy with the results. :beer:

    Performance Mods:
    3'' 02 housing 3'' Downpipe 3'' piping with resonator to SEE
    Stage 1 ECU
    Stage 2 WGA on complete ECU control boost, 0 preload, no vac line mods. Spiking weird. I would like to say 16 psi. He said it spiked at 19 for a fraciton of a second, then it wend down to 14 and went back up then down again. Might have to mess with the preload a bit.
    AEM Short Ram Intake
    CTI Chargepipe




    Stock with K&N Typhoon CAI it pushed out 220hp 232tq on a 92 degree day UNCORRECTED

    Glad I never went Stage 2.

    Wow! that's not just Stage 2 is it? You had more done to it? I've seen a Stage 3 only, on pump gas put down 314 to the wheels...so 311 with stage 2 seems very inpressive, or 314 with stage 3 in VERY un-impressive...

    Those numbers seem off to me. All 3 do. AFR seems high, and the hp/tq seems low to me.

    The dyno numbers I posted were from an almost identical setup and much higher with a very flat AFR dipping at the tail end.

    You were spiking higher I believe and didn't have the weird issue of the boost going up and down. There are SO many factors to consider. Every car is different.

    There actually was another silver SRT-4 with the same mods, except he had a AGP WGA off ECU controlled boost spiking 18-19 and holding 15 to redline, 3'' Borla turboback, Mopar CAI, only 22k miles on her and he dynod 259/280 as his highest. I believe my AFR goes up at the end is because of, again, the WGA. Boost goes back up by redline.

    The numbers are consistent as you can see with all 3 runs.

    I say that about the Stage 2, because a dude on 2gn dynod his Stage w2 with 230hp 286 torque.

    you might say that about S2 now, but my #'s speak for themself, and no I haven't dynoed it nor plan on it. I had S1 and with a cat back exhaust, AGP WGA, and CAI I went 13.30 @104 spiking 18 holding 15, S2 with full 3",180 t-stat exhaust and the above went 12.89 @ 111 still spiking 18 and holding 15 added map clamp and fmic went 12.61 @ 117 on a DR. I am throwing the slicks at it this year for now to see if any improvement. so I say S2 is worthwhile and I think you would like it also.

    I have also heard, don't know if it is true, but S2 cars always dyno on the low side.

    My car dyno'd 240/270ish with just stage one, and a K & N drop in filter...spiking 18+, holding 15 to red line...

    First of all, I must say to the OP that those are nice numbers..I forgot to mention that in my first post...

    And secondly.....I might have a little more then just S2....but with a good tune, I could easily squeeze out 335 or more with my set-up. The 311 was a 19 spike, 16-17 hold. I have the capability to spike 25 and hold 22-23.....:fear:

    Big turbo/ported stocker I am assuming. :thumb:

    Paulie,
    Quarter mile times don't matter to me. I never go to the track. My car is a daily driver and loves highway pulls. :usflag:

    If I wanted to go fast in the quarter mile I sure the hell wouldn't be in a FailWheelDrive car. :fart:

    nice numbers..

    im with ya about the track thing.. i just want the car to feel quick enough to me. i don't need to go to the 1/4 to prove anything.

    after a couple more small things, i think i am going to take my skittle to the dyno and see what happens.

    Nope we are pretty much running identical setups. I would spike 18 to 19, hold around 15 and fade to 13 at redline. Only difference is the exhaust brands.

    Actually those are decent numbers for those mods. I've yet to see an SRT-4 on complete stock turbo (meaning no porting and what not) achieve 300+ tq without any sort of tuning device. Not saying it can't happen or doesn't exist I've just yet to see it.

    My first dyno... I did 255whp with 311tq
    Mods at the time were:
    Stage 1
    AEM Short Ram Intake
    PTP Wga 21 spike dropping to I don't recall
    2.5" Side Exit Exhaust
    MapClamp

    This was on a DynoJet. So some of you who posted may have been on a different type of dyno like a Mustang dyno. Hence why your numbers might be higher/different.

    Here is a run I did on a dyno jet. S1 ecu, thermal 3" exhaust o2 back, mopar CAI with AEM dryflow, s2 wga spiking 19 holding 15 fading to 13 at redline. I'm not saying they are bad numbers just curious why there is such a difference especially in the AFR's.

    Temp/Humidity plays a role. Especially on pcm controlled boost.

    Every SRT-4 is different.

    Hmmmm maybe I have an exhaust leak. That cuases you to run leaner correct? I had a shop do my 02 housing. I brought in the copper spray a gasket that is recommended. And he used it. But boy did he have problems getting that lower heatshield off. lmao.

    My car has 60,XXX on it right now.

    Lol, nice master. I would love to upgrade my turbo in the future.

    Thought it would be a good idea to ressurect my old post. I am getting the car dynod again this coming Sunday. (Aug 10th) Can't beat a $35 dyno with AFR reading!

    All that has changed is that I no longer have the Stage 2 WGA on the car and the 3'' Side Exit Exhaust with single resonator is gone.

    I now have the stock WGA on there, stock boost levels, MPX 3'' Single exit with resonator and muffler.

    Curious to see how much power I will lose. Will post results after dyno.

    Weather should be a lot warmer, I plan on getting it dynoed early before it gets really hot.
