Good run JD! I expected more for the G8, but I'm not forgetting that I'd probably never set up a run from a roll in an auto car. Go from a dig and see if you can reel him in. Get it on video too so we can see the difference in how the cars pull. I'm not really worried about the traction issue, I just want to see if the v can still pull once you hook. Cause I'm pretty sure you guys will be pretty even.
I plan on recording this in the daylight...more to come.

I know I'm in the CTS-v forum, but I did say I wish I could've purchased a new cts-v. No need to hate on us G8's LOL We are all still GM not like I got a ricer...
With that said, I have a full pedders suspension kit sitting at the house waiting to go on. Pete at Pedders pulled over 1.03g's in a G8 with the kit on bridgestone tires. Anything can be made to handle. and still come out much cheaper.
The real deciding factor other than money was I don't really like the rear end on the cts-v's and they are smaller. You guys have a much nicer interior though. G8's I think look better, but have cheaper interiors. The extra room is a bonus on the G8's as well my family doesn't have to argue over leg room in the back.
It was all a compromise anyways if I had my way I would've bought a 06 z06, but 2 kids don't fit well in the trunk LOL

I'm w/ ya there Tempest! Not sure why some of these guys like to get in pissing matches over which is better. I love the G8's. The V's & G8's are both great cars. Havn't got a chance to drive one yet, but I will.
PS: I would have rather bought a Z too, but the lack of a back seat kinda killed that plan.

Here is an example, if you just want to drag the cars, the Pontiac will always launch better because in stock form Pontiacs always have ridiculously soft springs/shocks and the rear end squats like nobody's business. At least that is how it is with my buddy's 2006 GTO, his car squats and gets a bunch of traction off the line because of all that weight-transfer.
I launch off idle to about 1000 rpm, traction control off. I would say that bone stock, I am about 30% below 2.000 in the 60' times.

I believe the the two cars would be pretty close if they were both modded with the same parts. The V weighing less would almost always give it an advantage, though.
And it really depends on the mods, and what the car will be used for.

At least that is how it is with my buddy's 2006 GTO, his car squats and gets a bunch of traction off the line because of all that weight-transfer. He can get much more traction with all-season 245s in the rear than I can with r-compound 295s. My car doesn't squat at all, but I wanted it that way for superior handling. All other things being equal, the better launch for the G8 GXP might give a better E.T. than the CTS-V with a worse launch, but lower curb weight. This is very close.
But, that same suspension really sucks for handling, braking, or high-speed stability (basically every other aspect of a peformance car). Mod for mod, when it comes to suspension/handling stuff, the Pontiac will never compare to a V, the V has a better/more rigid platform to build on, plain and simple. There is a reason why these heavy sedans have the reputation they do for great handling and stability.
***And I will say it again as I have been preaching a lot lately, with the new aftermarket axle developments that have hit the market that kill the wheelhop, you will hardly ever be hearing about diff failures anymore. Basically the one crutch that our cars had can be eliminated with a pair of $500 half-shafts, which is why I have mine on order as we speak.***

I test drove a g8 before i bought my 05 V and hated the auto, and the not so luxurious plastic ***** all over the interior. Major turn off for me was no Navigation option. Other then the rear end in the first Gen V, I think tis a way better platform for mods then the g8. Never will a g8 gt outhandle a V and if it werent for the horrible rear, the V would be hard to beat. From a roll same mods, the V will pull a g8 all day long.
It is a very good run, but kind of lop sided in the fact that the OP is putting out almost 40rwhp more than the GXP. I raced a 2005ish CTS-V right after I got my GXP and with the only mod being transmission tunning I did myself. We ran from a 55mph roll and I pulled on him just like the OP did this GXP in the video.
40mph is a really bad spot for a roll race in the GXP as the A6 auto first gear winds out at 28mph and 40mph puts the auto in the low end of second at about 2400rpms.
Good run, both cars are very formidable and great platforms. The CTS-V is a very refined car, the GXP is a high horsepower brute with great handling, great brakes, awesome motor and is not setup as a refined car but as a high performance sedan at the end of the day.

That said we raced from 20, 40, 45, 50, 55mph and the GXP never won. Not only that I let him hit it first every race, no honking just like the video. I pulled after 3rd gear every time.

**** so many haters in here.
Ultimately the big picture goes like this.
A Pontiac G8 is not a CTS-V.
A Cadillac CTS-V is not a G8.
They are two entirely different cars.
If you want to start comparing cars on the same time line, pick cars that where both produced during the same production cycles. If you're still bickering about which is faster, than you need to go to the import forums.
This guy posted a vid of his run, if you want to state your opinion. Post a vid.
Cheers.
