2002 Pontiac Firebird Trans Am WS6

Discussion in 'American Cars' started by notecedar, Sep 1, 2004.

  1. but after 98 it was only the hood and spoiler. and what makes the exhaust high flowing then a regular exhaust (ie on my z28) is bigger diameter?
  2. The parts that I listed is from a 2002 WS6 if I remember correctly.

    And yes the exhuast is a bit bigger, the result is while Z28's and firebird Formulas dynoed at about 295-305RWHP the SS and WS6 dynoed at about 310-325RWHP from what Ive seen. the 345BHP C5 dyno's at 295-305RWHP and the Z06 Corvette dynos at 345-355RWHP which is about 410-420BHP. Reason for big under rate is to not upset sales of the C5 orvette, and I am unsure as to how much the FireHawk is putting out.
  3. Up until a certain year, you are partly correct.

    The WS6 was doen as a "tier 1" SLP car for a few years. In it's later years, it was still done by SLP, but as a "tier 2 car". I don't know what the hell that means, but WS6s were done by SLP in certain years. I don't remember which ones, and I don't care enough to find out.
  4. It doesn't have a "cold air intake system". It doesn't have any different exhaust manifolds.
  5. No. Ram Air does nothing on a dyno... and it does practically nothing in the real world either. Once you hit 100 mph, you can count on Ram Air to provide you with 3 extra horsepower. Whoopty-#$%#ing-do.

    Part of the discrepancy between the numbers you have heard are the different years of the LS1. 1998 and 1999 LS1s typically dyno the lowest. 2000s next... then the 2001 and 2002s. Then there is also a certain variance to be expected form engine to engine. Then there are all the different dynos out there recording these numbers -- different altitiudes, different temperatures, different humidities... and to top it all off -- you factor in that the LS1 is one of the most-tuned engines in the country. People everywhere are tuning and dynoing their cars.

    You have cars from different years, in different weather, being measured by different machines, and different factory variances... there is no wonder the dyno numbers you hear are all over the board.

    A typical auto LS1 f-body will dyno between 295 and 305 rwhp.

    A typical 6-speed LS1 f-body will dyno between 305 and 315 rwhp.

    You do indeed have your freaks putting out over 320 rwhp -- some even 325.
  6. I hope they become harder and harder to get <A BORDER="0" HREF="http://www.supercars.net/emoticons.html"><IMG BORDER="0" SRC="http://speed.supercars.net/pitlane/emoticons/smile.gif"></A>

    "Trans Am" is simply a trim level for the Firebird. The Firebird is a basic V6 3800.

    The Formula is the next "step up" -- it has the Firebird body (the lightest) and few options, but it does have the LS1 motor.

    The WS6 package was offered on the Formula Firebirds until the model year 2001.

    The Trans Am is the next step up. It has teh Trans Am body styling which includes some minor ground effects and a high-profile spoiler. Stuff like leather seats is standard. The Trans Am is available with the WS6 package - which is the bad ass looking hood, along with other minor upgrades that really don't do a heck of a lot.

    The Firehawk is the next step up. Limited production, and even more minor upgrades that don't do a heck of a lot.

    Contraray to what many people have said in this thread, there is no statistical evidence to show that the Trans Am WS6 makes more horsepower than a Camaro Z28 beyond a standard deviation of the LS1 engine itself. Some WS6s will dyno higher. Some Z28s will dyno higher. Big farking deal.

    An LS1 f-body will run a mid 13 at about 105 on average.

    Your strong car, when coupled with a strong driver, is capable of breaking into the 12s.
  7. I obviously know nothing about this car.
  8. Say what I want? Where is this info comming from?

    My info comes from the cars I've actually owned and worked on and even worked on my buddies cars.

    One more thing...there is no such thing as a free flowing exhaust manifold...when you consider stock 02's and EGR's a free flowing exhaust manifold is useless...besides...the exhaust manifolds are the same as the ones on my buddies Z28...same old rusty ass POS with flimsly aluminum foil like covers on top.

    Until you actually own and work on these cars...I think you should stop trying to contradict the ones who do.
  9. I give up kid.
  10. Kid?

    MotherF-ucker I'm 24...and I think I know more about my car than you do.

    And how in the hell did you get my pics of my SLP door tags?
  11. But seriously though...elaborate these "Free flowing exhaust manifolds" you talk about.
  12. SC.net sux balls so bad...I don't know how they got on that dude's reply...but I'm reposting these pics of my SLP door tags.

    This is what you look for on an SLP "Tier 1" car <A BORDER="0" HREF="http://www.supercars.net/emoticons.html"><IMG BORDER="0" SRC="http://speed.supercars.net/pitlane/emoticons/wink.gif"></A> (Jay...you F-A-G) <A BORDER="0" HREF="http://www.supercars.net/emoticons.html"><IMG BORDER="0" SRC="http://speed.supercars.net/pitlane/emoticons/smile.gif"></A>
  13. i've worked on an 2000 ss and my 1998 z28 and seen no exterior difference between exhaust.
  14. Oh great, why am I saying exhuast manifold. I am thinking of a different car. My fualt, The drugs I am on for my high speed car accident is cuasing me to make mistakes and giving me a low temper. I should be getting along with Fbody owners anyhow, my mistake on the exhuast manifold.
  15. an 03 cobra only has 365 RWHP so I don't see how an WS6 Firebird could have 345RWHP when the cobra starts out with 65 more horspower then the WS6 and the Firebird dosen't even have that much power to start out with in the first place. I believe the SLP motors were under rated but they did not have 345 RWHP
  16. no one said 345RWHP, if I did thats a typo. 345BHP for the non WS6 Firebirds and more for the WS6 Firebirds.
  17. Becareful how you say that...because 2001 and 2002 WS6's had more than 345hp at the crank...98-2000 SS's and WS6's had about 348 crank hp...when I dynoed my SS it did 300hp at the wheels...calculate that with drivetrain loss at around 15% and that's 348hp or somewhere near there...01's and 02's had more due mainly to the LS6 intakes that they were given and a more mild cam.
  18. True, however there are other reasons for difference's in dyno results. And this thread is for the 2002 WS6 Trans Am.
