Pontiac Bonneville



  • intense01intense01 Posts: 107

    I never did try these folks out yet. I've been too bogged down with heavy duty engine mods. I would say that somewhere around mid-summer I will rethink my position on not being able to go faster than 126 mph...

    Picked it up today. Cost of tire itself: $285 Cdn. (about $185 US) plus installation and taxes (15% in Ontario!). How does $225 US sound as a grand total? Ouch! Given that my dealer gave me a loaner Regal GS for the two days I was without the Bonneville, I'm happy to buy it this way rather than over the net - but it still hurts!

    BTW, the RSA 235/55/17 actually lists for $357 Cdn. (about $230 US) in Goodyear catalogues up here but local Goodyear dealer explains that this is out of date and $370 is more like it. I am suspecting that, given that this is not a commonly stocked tire, that local supplies will not be abundant - nor will discounts.

    I have bookmarked the tirerack and tiredepot sites because this experience has started me thinking about tire replacement. My mechanic informs me that 235/55/17 will NOT be an easy size to replace and that the RSA is a damned fine tire - particularly as an all-season high performance tire that works well in snow. Unless I want to get a 2nd set of Hakkepelitas for the winter (yuck!), I might not have much choice on the matter. However, he did say that he could probably put Michelin Pilots on for close to the same price.

    According to my mechanic, other than the above 2, the only other tires available in 235/55/17: Bridgestone Turanza Z RevoMichelin Energy MXV4 PlusGoodyear Eagle LS.

    I can say that I love the RSA's - very sticky and the built-up sidewalls let you throw the Bonnie into tight corners with confidence, zero squeal and no added roll (that's probably the 55 profile). I cannot compare ride comfort with another tire because the RSA's are all that I've had on this car.

    Any recommendations or comments?

    A couple of options. A 255/50-17 tire is about the same circumference as a 235/55-17. Seems like there is a bigger selection in that size. I'm not sure if a 255-series tire will fit on your rims or not. I think the Bonnie has 17x7.5 wheels. Another option is to move up to 18x8 wheels. Expensive, but then you could use 255/45-18 tires. I think intense01 has that setup.

    Good luck.

    Stephen -

    Did you happen to be driving north on I-95 in the Georgetown to Newbury Mass area on Sunday afternoon somewhere around 3 p.m.? If not, I saw your car's twin as I headed south to PA. I remember thinking it was the first SSEi or SLE I had seen in that color - very nice by the way.

    I'd love to see a Bonneville meet in our area too - maybe a Sunday afternoon sometime in late June? I'll help but can't do it all. How wide shall we open the invitation? Based on participation in NJ, I think it would be good to get a buy in from a few other car types to make it the most fun. I'd like to see Grand Prix, Impala, Regal, Aurora and Intrigue, and Cadillac join us - what are your thoughts?

    Forgot to mention that I was opportunistic enough to have them reprogram my and my wife's name (her name is Daryl - and, unlike our fair Xena on this board, that is her real name). So, they are now centered and we've gotten rid of those colsarned vertical lines.

    Nice touch - my boss commented on it today.
  • theicemantheiceman Posts: 736
    Thanks for the 18 in. suggestion but I'm not sure that I'd like the expense (of new wheels), the look or the ride. On the other hand, it could let me put performance snows on the 17" rims and keep a real performance touring tire on the 18" ones.

    Has anybody else done this - and lived to tell the tale?

    BTW, spoke with my dealer today & thanked them for all their help with the tire. As we got talking, something didn't sound right to him and it turns out that I may have been over-charged by about $50 Cdn. (about $32-35 US) so I'll be getting a refund.

    Surgenor Pontiac Buick GMC - best dealership in the Ottawa area (IMHO).

    This was an unscheduled visit to the dealer but it was at the 6000 mile mark, so I had them change the oil (58% life left according to the DIC oil life monitor). Unfortunately, because it was unscheduled, I didn't bring any synthetic with me - we'll have to wait until the next one.

    We're heading into our first warm-weather holiday weekend this weekend (Queen Victoria Day - rather quaint, 'tisn't it?) so I hope to make some headway on that "honey do" list.

    Have a good one yourselves! Dan

    No, it wasn't me on Sunday in that neck of the woods. I was with my mother in Framingham. As far as a meet goes, I wonder who else involved in these Bonneville discussions would be interested.
  • HenryHenry Posts: 1,106
    Let me know so that my Olds and I can crash the party.

    Don't worry, I'll keep the car in second gear. ;)

    Took the SSEi to the track yesterday, and got five runs in. My best three looked like this:

    2.169 9.218 @ 76.94 14.242 @ 97.45
    2.197 9.202 @ 77.82 14.230 @ 98.48
    2.255 9.188 @ 78.26 14.163 @ 98.50

    2000 SSEi
    Stock: 15.800 @ 89.60
    4/14/01: 14.555 @ 94.75 mph
    5/19/01: 14.163 @ 98.50 mph

    Hey if I can get to NJ - you're certainly welcome up here in these parts

  • boosted1boosted1 Posts: 90

    You are a true pioneer.

    Keep up the good work, you are paving the way for the rest of us. As soon as my warranty is up I will be trying to keep up with you.
  • theicemantheiceman Posts: 736
    Those are some darned impressive numbers for a heavy FWD vehicle. I've forgotten what kind of rubber/wheel setup you're using - or do you keep a 2nd set for track use?
  • theicemantheiceman Posts: 736
    Here's something of mild interest: I was in Carpoint recently and checked in on the reviews of the '00 Bonneville. On the whole, they're very good - an average of 8.8/10. I thought I saw a pattern and dug a bit. Firstly, about 40% rank our cars as 9.5/10 or better and only 13% give their cars less than a 8/10 over all and there were no scores under 6.

    While SE owners are, on average, somewhat less generous in their scores than owners of SLE's and SSEi's, the gap between their appraisals and the others is less than 3%.

    These numbers fare well against those of the '00 Toyota Avalon (8.8), BMW 3 series (8.6), BMW 5 series (8.8) and Acura TL (9.0). Where the Bonnie falls short of these others? The interior. We give ours an 8.4 whereas the others attract 9.2, 9.0, 8.9, and 8.6. Does this give you any ideas about where Pontiac should focus future improvements?

    Although the sample size is small (116 cars for the Bonneville) and unscientific, it's probably every bit as good as what Consumer Reports uses.

    I would be interested in a meet in the New England area.

    Does everyone follow the suggested schedule for rotating tires?
  • theicemantheiceman Posts: 736
    I certainly folow it - the advantages are that they last longer, the ride and traction stay better longer and you reduce the likelihood of putting your suspension "out of tune".
  • intense01intense01 Posts: 107
    Thanks for the positive feedback guys! It's nice to get a little recognition every now and then.

    By the way, I forgot to mention how fun it was to run 14.16 while at least three newer Mustangs (two slightly modified GTs and one stock Cobra) were all running 14.30 to 14.70...

    My everyday tire/wheel combination is 18 x 8 Konig Villains with P255/45ZR18 tires. For the track, I put some 17 x 8 Konig Villains with P275/40R17 Nitto Drag Radials on the front. They don't make much difference right now because I don't have much of a traction issue off the line (yet).

    Keep going -- thirteens are right around the corner. You're approaching stock TransAm/Z28 times with a 3600lb front wheel drive car. Unreal!

    If you ditch the rear seat cushion along with the spare tire that may get you over the hump.

    Got the Stage 2 and AFPR in today. Haven't got a chance to run it with the monsoons here. To anyone that has one how soon before the check engine light goes out? And how much fuel pressure are you running? Matt

    Since I couldn't remember my password from home, I registered under a new name from my cousin's computer in Maine. I've been incommunicado for the last week travelling so it was good to see what was happening in Bonneville land. I think in my whole 1250 mile trip out here that I only saw one Bonneville and that was in Michigan. Either I'm not very observant or there really aren't that many out there. Of course, in Maine you're nobody unless you have a 4 wheel drive or a Subaru.
    I'm fascinated by the fact that Scott can achieve those times with front wheel drive and without any form of positraction. How do the pocket rocket/rice burners do it since when I've seen them on television, they are spinning both tires up front? Scott, what are your shift points set at?
    Ken, how can I contact you about delivering the stabilizer bar?

  • intense01intense01 Posts: 107

    The Stage II and RAT AFPR should NOT set any codes whatsoever.

    You'll want to get an Autotap or Tech II and see what code(s) you're setting as soon as possible. This way you can determine how bad the situation is, and also formulate an action plan to rectify the situation.

    As far as fuel pressure goes, I don't really know what mine is set to, because I haven't yet verified the accuracy of the Casper's gauge. It showed 46 psi static stock, even though my manual said the stock setting should be 52 psi. Regardless, I have it set to 58 psi for maximum performance, which is 12 pounds over my stock setting, and may actually be as high as 64 psi.

    Let me know what code(s) you have, and we'll figure out how to proceed. By the way, you may want to reset your PCM if you haven't already...


    My shift points are still stock, as I still have the stock PCM. I get the best performance by leaving the shifter in '3', and letting it shift when it feels like it - usually 5,600 to 5,800 RPM.

    Can you email me? My address is in the profile. I'll give you my phone number then.

  • refinerrefiner Posts: 59
    Scott, The instructions that came with the Stage 2 said the SES light would come on till the PCM adjusted to it. But it sounds like your SES light didn't come on. I'll try to have it checked out today. Thanks Matt

    Has anyone noticed if there is a way to defeat the daytime running lights? Over in the Impala forum someone mentioned that they need to turn off lights when entering a military base and couldn't figure out how to do so. It got me wondering about our cars. I see that I cannot turn mine off either.

    If you turn on the headlight switch for parking lights, the DRL remain on (apparantly this defeats DRL in some cars - not mine). When the auto headlight sensor thinks it's dark enough, the regular lights come on - so again you have headlights on, though not DRL.

    Anytime the car is in gear it appears that either DRL or headlights will be on.

    I don't have a need to defeat them - just wondering.

    Any comments?

  • homer2000sseihomer2000ssei Posts: 159
    Actually - while I almost always turn my headlights on - yes, during the day - i too am interested in an easy solution to the constant lighting feature. I switched all my bulbs to "brite white" and like the blueish color of them , but sometimes I would like to have them off when the mood strikes.
  • HenryHenry Posts: 1,106
    Okay you Bonne Boys have got me thinking. All this talk about the MagnaSteer being adjustable has got me wondering about my HUMBLE Aurora. Talk has it that the 2001 Aurora has Magnasteer II which is adjustable. The question is whether the Magnasteer on the Classic (94-99) is adjustable. Is every Bonneville that has magnasteer adjustable, or is it only certain years? If there is a 1995 Bonne with magnasteer that is adjustable, the future would look good for my humble 1995 Aurora.

    ALL opinions are welcome.

  • mlm4mlm4 Posts: 401

    You piqued my curiosity. I think DRL is a great idea, but I have never liked the fact that it is fully automatic. As the pilot I think I should have ultimate control over such things as lighting (at least I have the ability to defeat the automatic door locks!). Anyway, I went digging through the service manual and learned the following:

    The DRL will operate when the ignition switch is in the ON position, the gear selector lever is out of the PARK position and the ambient light sensor indicates daytime conditions. I haven't checked, but I think on my car turning the headlamp switch to the PARK position will turn the DRL off as it does the headlamps at night. Of course, the parking lights will now be on.

    The only way I can see to disable DRL is to pull the FOG/DRL fuse (located in the underhood fuse block), which will still allow the high beam headlamps and flash-to-pass to operate, but will unfortunately also disable the front fog lamps (the Aurora is the only one with rear fog lamps). You can't pull the DRL relay because it is part of the high beam headlamp circuit, and it might also cause a DTC.

    The rest of this post is probably Too Much Information, but maybe someone will be interested. In DRL mode, the left and right high beam headlamps are placed in series. Remembering your elementary circuit theory, assuming the resistance of each lamp is the same the voltage will be split evenly between the two lamps, causing them to burn at half intensity. In high beam or flash-to-pass mode, the lamps are placed in parallel, allowing the full battery voltage to cross both lamps. The circuit switching is done by the Dash Integration Module (DIM), which is one the many microprocessors aboard the new Bonnevilles. Chances are the logic is in software. That opens up the possibility that the DRL feature is "user" configurable. The service manual describes reprogramming the DIM, which is done after it is replaced. This is the same procedure the dealer uses to change the Magna Steer setting and the DIC greeting. The manual describes the various menus the Tech 2 scan tool will display during this process, including two called "Miscellaneous Options #1" and "#2". Unfortunately, it does not describe the options other than to say "follow...the on screen instructions." Without a scan tool or more detailed documentation, I can only speculate that there may be an option to enable or disable the DRL. If I were designing this, I would put that option in. On the other hand, since GM considers DRL to be a safety feature, they may not have the provision to disable the DRL. Perhaps someone with access to a scan tool can enlighten us?

    I definitely follow the recommended rotation schedule. It allows for balanced wear and I always notice improved ride after rotation.
  • tpkentpken Posts: 1,108
    Mike - I tried turning the headlamp switch to Park as you mentioned - but no - it did not turn off DRL - just added parking lights.

    You've got to be right - no way to defeat it short of pulling the fuse. I don't have any need for that and enjoy having the driving lights on when the car is in gear - but I agree it is better to have the ultimate authority over the vehicle.
