16 secs @88 mph???!!! Was that GXP pulling a trailer? Sounds about right to me. This is why I always thought My Aurora was almost as quick as my GXP. |

For some reason I would expect it to run 14.8, 16.0 does sound too slow for a car with 275 hp. Check out part of another review...
"The GXP is actually the premium model of the made-over '04 Bonneville, and it's now a car for grown-ups, a lot like the Oldsmobile Aurora that we remember so fondly. Just as in the Aurora, there's a DOHC Northstar V-8 now driving the Bonneville GXP's front wheels, and an added benefit is the same four-speed automatic transmission with adaptive shift logic. It's a responsive powertrain that makes you wonder how we ever put up with the soggy supercharged V-6, and it gets this 3790-pound car from 0 to 60 mph in 6.5 seconds." -Automobile Magazine
A 1997-03 GTP can run 15 flat with only 240 hp... and I just read a review for an 04 GTP Competition Group and it also runs 15 flat with 260 hp. I'm assuming it's bigger and heavier than the 97-03.

Very very wishful actually the supercharged stone age 3800 series 3 with 260 hp would have been a better choice for that car but Pontiac was trying to aim at refinement over low tech cheap power. |

GTP is a W-body, not a Bonnie. The W-body is about 2-300 lbs lighter. Where are the bonneville club guys? What do those GXP's run in the hands of owners? I'd think they'd do low 15's high 14's depending on the weather, etc. |

Guys there think putting an intense sticker on your Bonneville make a non-supercharged car supercharged and so on. |

A I'd think they'd do low 15's high 14's depending on the weather, etc. Drive a GXP some time so you too can wonder how that can be 275 hp under the hood too. I loved the looks of the car don't get me wrong but it was just disappointing around town but on the highway above legal speeds it was pretty good. |

Plus the 4.6 burns oil like crazy even brand new ones? I just walked a STS seville the other day and I only have a 4.4 lol Alright that's it. Going to Tennessee for Thanksgiving. Gonna have to meet on some neutral drag strip in VA or somewhere...  |

I know the GTP is a W-body, I used to own an 01 Impala. I was thinking the difference in weight would be made up by the extra 15-35 hp (GXP). Depending on if it was a 240 or 260 hp model GTP. I also thought a GXP would run high 14's - low 15's...  |

Ok, I have never ran my GXP at the track, and I'm not bashing my old 97. But, by feel of the pants, anyway, this GXP is faster than my 97 was by a long shot. I for one am very impressed with the 4.6 and it has not used a drop of oil in 3200 miles. Just my opinion.

I like the looks of a bonnie GXP and I to think they are faster. I've been next to some when they take off and they seem like they have more torque in the front wheels then we do. I never have raced one though. So IDK

You will have a SES light, but no torque management.  |

I just came to the conclusion the Bonneville GXP is no stoplight racer but a great highway cruiser. If you do a search I have posted a 0-110 video with my GXP on this site. I was not able to find the post???

Just to throw it out there, the '94 STS that I just bought feels a good bit quicker than my aurora did. Granted, it's got 295hp over 250, about 75k less miles on it, and it smaller, but it weights almost the same. Maybe i was used to the 3.48 gears in me non-AB aurora over the 3.71 gears in the caddy. It might make it seem quicker.

The pre-98 STS is a fair bit lighter than the 98+ one. Though it's on a less impressive chassis. 1998 MY is when the Seville moved onto a version of the Aurora's benchmark chassis.
I've kind of forgotten what the point here was? If it is whether or not the 4.6L is better than the 4.0L, absolutely, at least in terms of power.

I have a 02 SSEI my wife drives. From a light it will leave my 97 Aurora. On the road I pass better, in the refinement category, no contest, I love my Aurora, handling my poly modded Aurora is close but the soft 16" tires can't stick and flex much more then here 17" sport 245's
she also has beefier swaybars. Ride quality the Aurora wins hands down.
I am looking to get a GXP replacement for her SSEI. I just don't like the charged six. Those guys on the bonneville forum do love the six, mostly because there is no limit to what you can do for mods on engines and transmissions.
BTW the 4t65HD sucks compared to the 4t80 for shift smoothness and again refinement.

Quoted for truth.
FWIW my stock L32 feels a lot faster then a stock L67 (in GP form anyway). However I've noticed that on the hwy my Aurora lights up the rev band at speed way better then my GTP does. This is to be expected as the nature of the 2 engines are totally different. Back to ontopic, I see no advantage over in putting in a 4.6 in an Aurora over the stock 4.0 unless you have the knowledge and desire to beef up the supporting mods to get a lot more out of the 4.6.
I'm still waiting to drive my first Bonneville GXP...I've driven a G8 GT but have yet to find anyone with a Bonneville GXP for me to try out.

If I ever get down to Cincy, I'll be bangin down yer door for more then just a drive in the GXP *cough Final 500 cough*
My friend just bought a Panther black G8 GT...its a fantastic car. Balanced, powerful, unassuming - essentially everything I like in a car.

Balanced, powerful, unassuming - essentially everything I like in a car. The G8 GT I test drove a few months ago is worlds quicker than the Bonneville GXP I owned around town. never got a chance to take it to the highway because that's where the GXP and its 4.6 seem to really shine. Around town I put the G8 GT at slightly quicker than my 745i but I could just be going by the G8s fantastic V8 rumble which the GXP bonnie had going for it as well. |

From the VIN# on the 05 GXP Bonnie I found on E-bay, GM says they made 4193 cars GXPs that year. I just need a VIN and I can get production figures on most any GM car. |

well then that makes my life easier if and when my 4.0 kicks the bucket ..... ;D whats the power rating of the 4.6 compared to the 4.0 hp and tq ,justin Idk I owned a 2005 Bonneville GXP with the 275hp version and it felt like a slug. I liked my Auroras 4.0 response and performance much better. Plus the 4.6 burns oil like crazy even brand new ones? I just walked a STS seville the other day and I only have a 4.4 lol I thought the same thing when I test drove an 05 GXP awhile back. Didn't feel all that much faster if faster at all than an Aurora |

Didn't feel all that much faster if faster at all than an Aurora I had a Lucerne CXS w/ the 4.6 as a loaner and I remember being underwhelmed performance-wise. Not sure if that was due to tuning for the Buick audience, low-octane gas, or whatever but my Aurora (which does have the Autobahn option) feels snappier. I guess really, in this case we're only talking a diff. of 25 hp between two different vehicles anyway.... But I am sure you'd notice a difference going from 250 to 300hp in an Aurora. Edit: Woah, this thread is an oldie! |

I would never bother popping in a 4.6L into my Aurora. Too much PIA... I would rather just pop in the 4.6L cams and call it a day. My 2G has the 3.7 gearing. Now that tuning is available it be the most cost effective process. Besides it seems the 4.0 is much more reliable than the 4.6.
Now someone needs to figure out how to make fiberglas body replacement parts for the Aurora to lighten this sucker up....then it be completely badass haha!
Im working on a pure poly trans mount right now, so hopefully it works out well, but the plan is there will be no give when I floor it so I m expecting good response from this mod.
