Pontiac GTO



  • And we meet again! Good to hear from you Cracovian. You are correct, I was considering a Mazda 6, but in the meantime I found a killer deal on a new Jaguar X-Type(stick shift) and so I traded in my Axiom for the Jag. I love the Jag especially with AWD, but GTO is what I want now. I know what you mean regarding the construction zones in Chicago, but there are still plenty of good roads, where you could "open up" your GTO. How about an Axiom with 400HP GTO engine?

    After buying an 04 GTO last Dec I decided to keep my very comfortable 99 Olds Intrigue GLS for the winter. GTO tire pressure was almost 60 lbs each tire the day I brought it home. Lowered the pressure to 35. I never felt the GTO gave a "pleasant ride", I always thought it was a little hard. I lowered the tires to 32. No difference. At 8000mi I had the tires rotated and the next day there was a shimmy in the steering wheel above 50mph. Had the tires balanced and now I have never been so happy with driving the car. From the get go the car always felt a little jittery over small bumps, but it seems a tire was out of balance maybe it lost a weight when those tires were rock hard. I'm driving on stock 17s. Sometimes it's the simple things that are overlooked.
  • I have been looking at the GTO's for awhile now. The $3K cash-back got me looking harder (although I missed the extra $1K that ended 11/13. I took my first test spin 11/17. WOW! My first thought was whether this car was worth a couple thousand more than a Mustang GT. After driving the Mustang, it wasn't much of a decision. Looks aren't as important to me as horsepower and torque (although I actually like the looks of the GTO). You see a 100 Mustangs every day. You might see one GTO a week. I took my wife back yesterday to let her drive it. She insisted that I must be having a mid-life crisis. I asked her if she remembered how to drive a stick and cautioned her about the power. During our test drive, she caught the attention of some guy in a yellow Vette. You should have seen the smile on her face when she actually passed him after getting beat off the line. Who says a woman can't have a mid-life crisis as well. $28,999 out the door. I can't wait until Monday to take delivery. I'm thinking I may have to hide the other set of keys.
  • has anyone else complained of drivetrain whine.I just got my 05 back from dealership,they replaced the dif carrier assembly.
  • eliaselias Posts: 2,120
    the 40 mph whine happens no matter what gear you are in?
    i find that 5th is right for 40 mph and do not recall any objectionable gear noise/whine. i'll listen for it after i can drive again dec 6.
    also, have you checked the back seat for very whiny short passengers - i often find one or two of those in the back seat of my 05 m6 goat.
  • the whine was most noticible in 4th when light on throtle. dealership said gm tech was aware of problem and i was put on waiting for whiny passengers they are unable to speak for a while after a ride.
  • I checked the air pressure yesterday-the fronts (cold) are at 26lbs, and the rears at 27. Now I'm wondering if that is too low. Would that account for a "bumpy" or too firm a ride? I've had the car since late July...the car drives straight and solid and no shimmies or jitters...I really don't think the tires have any balance issues. I really just think that I need to get used to the harder/firmer suspension of this car and realize its ride is not going to be as good as a bonneville for soaking up bumps!
  • eliaselias Posts: 2,120
    26 psi is way too low imho, maybe even below some minimum spec. 26 makes the ride softer/squishier and handling worse and tire edges will wear too fast. i recommend 32-34 psi.
  • I too recommend 32-34 psi all the way around although the recommended psi sticker on the car says 33 psi front and 39 psi on rear.
    But that is if one is carrying a full pay load, two passengers in front and two in back.
    I have the 18" tires so maybe the 17's have a different
    recommendation? I run 34 all the way around.
    The stiff suspension is the price you pay for better handling.
  • Could anyone tell me at what rpm the automatic GTO would run at 60mph and 70mph? If I am not mistaken the manual will run 1550 rpm at 60mph. Thanks.
  • b4zb4z Posts: 3,372
    Well, let's see....
    the M6 has a 57% overdrive and the AT has a 70% overdrive.
    So there is a 22.8% increase.
    I would say about 1903.
  • As long as they share the same rear dif gearing...
  • rorrrorr Posts: 3,630
    How much you wanna bet the automatics have a taller (smaller numerically) rear-end gear......

    What b4z needs to do is to multiply the overdrive gear ratio by the rear-end gear ratio to get the final drive numbers for the automatics compared to the manuals.
  • hammen2hammen2 Posts: 1,313
    They both have 3.46 gears.
  • rorrrorr Posts: 3,630
    Well, I'll be a monkey's uncle...... :blush:

    I don't understand why the M6 doesn't get much better mileage than the A4 on the highway then, since the M6 is doing some SERIOUS loafing in 6th gear compared to 4th in the A4. :confuse:
  • hammen2hammen2 Posts: 1,313
    I believe it's rated at 29 mpg hwy, versus 21 for the A4 (though my Predator-tuned A4, on 93 octane, using the cruise and no A/C, will get 23 mpg at 70+ mph - must be all of the Zaino on the car :-)
  • rorrrorr Posts: 3,630
    ...must be all of the Zaino on the car

    LOL! Sounds like a good Mythbusters topic......
  • b4zb4z Posts: 3,372
    I was actually expecting better mileage in my M6.
    Just drove back from H'ville, NC. Downhill all the way from 2400' elevation to sea level.
    Average slightly over 75 mph.
    Spent about 45 minutes following a Volvo at 88mph.
    Average was a 23.5mpg.

    On the way up at slower speeds(closer to 80mph) gas milaeage was only 22.6mpg. had to go up in elevation.
    The only time my GTO will get over 29mpg is at 55-60mph or a little less.
    A lot of guys are reporting higher mpg than mine.

    Also remember that the M6 is actually the M12 transmission from the Z06 and has a 57% overdrive not the 50% overdrive that was in the base Corvettes, Fbods and Vipers.

    Gas mileage would be even better with that transmission.
  • I just replaced the OEM tires on my 2005 with winter tires, Dunlop M3, and there is a noticable difference in the ride quality actually less hard rather than more hard as I had expected. And yes the tire pressure on the OEM tires had been checked to agree with the recommended pressure. Also there is no appreciable difference in handling in dry conditions, then again I am not pushing the car to its limits. Probably will be able to test the handling in snow this weekend.
  • 2005 6-speed w/ 17" tires:
    70 mph = 1750
    80 mph = 2000
    100 mph = ???? (I was too busy watching the road!)

    Advertised MPG:
    4-speed auto = 16/21
    6-speed manual = 17/25
  • 100mph = 1700rpms

    Does anybody have a picture of an 06 Torrid Red with the darker tail lights?

    Do they exchange out easily if I wanted to replace with the 05 style instead?

    I am going to order an 06 as I had to pass on the 05 because no where to store it for 4 months and I just figured why not buy new in the spring rather than have it sitting for another 4 months after it sat on the dealer lot for 2 months and then in the showroom for a month with who knows who messing with it. I guess I prefer them new right out of the box.
  • hammen2hammen2 Posts: 1,313
    Not a Torrid Red, but the new Spice Red for '06:

    I got the CV8-R tails from JHP for $300 shipped back in late May. It took me 10 minutes in my parking lot at work to swap the tails and harnesses - very easy (just don't touch the bulbs - use rubber gloves if you must).

    I'm sure that there are plenty of '04-'05 owners who wouldn't mind switching with you if you don't like them.

  • zingerzinger Posts: 61
    Thanks Robert.

    I also passed on the 05 because it had some very minor damage that I mentioned previously (slight scratch on the side mirror case, above the rear GTO plastic panel).

    Since I plan to order an 06 I would like to get it right off the truck before it is handled by the dealer. Has anybody accepted delivery right off the truck? They can still do the PDI I would just like to be there to inspect and be sure they do everything right.

    Does anyone know how the order process works? How much down, etc?
  • hammen2hammen2 Posts: 1,313
    How it works depends on the dealership... many won't take orders for fear you'll bail on the car before delivery. Usually, those that have ordered have put $500-$1000 down. Make sure you write up paperwork that spells out who gets the $$$ if the order is cancelled. Also be sure to spell out, on the paperwork, what you want them to do and not do when the car arrives - remove the Wrapguard, remove the spring compressors and rotor shields, lower the tire pressure, check all fluids, et. al.

    Ordering an '06 will probably take 6 months to actually get your car - may want to talk to dealerships and find out what they have ordered. One good thing with the GTO's relative lack of options is the likelihood that you can find the car you want - exterior color, interior color (on some combos), transmission, 18" wheels are the only significant options - I would have to believe that a dealer somewhere close to you would already have the car you want already coming in...

  • zingerzinger Posts: 61
    I want see the car come off the truck and be sure they dont give me a wash I dont want. The rest of the stuff is fine. This would be my first brand new car purchase and I would like it to look and smell new. The 05 I was considering only had 40 miles but didnt have that new car smell or feel - probably because it had been sitting for a couple of months.

    The dealer I have been working with is saying the 06's will start arriving in Feb. Only problem is I really dont want one before march because of the weather. My house is under construction and I cannot use the garage so I have no where to store it. So I have timing issues.

    I read one of your earlier posts regarding replacing the rear speakers. Is this something you would consider easy enough to trust a local family owned stereo shop to be able to do?


  • zingerzinger Posts: 61
    Did they change the gauges for 2006?


    This may force me to track down an 05.
  • hammen2hammen2 Posts: 1,313
    I don't believe that they've changed the gauges on the '06's - most likely a wrong or incorrect photo.

    I believe those are Monaro gauges:

    Note that the pics on the Forbes Auto site of the blue interior show the '04 gauges...
  • hammen2hammen2 Posts: 1,313
    If you want to make sure they don't give you a wash, put it in writing that the car be delivered with the WrapGuard still on it. They're supposed to remove that as part of the PDI, along with the plastic covering the interior seats.

    I would sign an agreement stating what they could and could not do (ask them for a copy of the PDI, and say yay or nay to specific steps).

    '06's have arrived at dealers almost nationwide. Several others on other GTO sites have received their '06's today.

    I did the speaker replacements myself, following the instructions posted on another site, and had no issues with it. I'd imagine anyone who does this regularly for a living would have no problems with the disassembly. I'd strongly suggest throwing some Dynamat or other sound-deadening material in there while you have the rear seats/back panels exposed. I plan to do that next year when my car comes out of storage :-(
