A GTO followed me on a long ramp and zipped around me when we hit the highway. I was very impressed by the acceleration and stupidity. Seemed much faster than my C5, but I didn't chase him. Maybe his was modified?

We sold our '05 GTO for the vette. The GTO would scoot pretty good,but it probably still wouldn't out run the vette. The GTO is a hog at a little over 3,700 lbs.I think the C5 vette is around 3,200.
The LS2 was upgraded with:
Cylinder bore diameter increased to 101.6 mm (4.00 inches), increasing displacement to 6.0 liters or 364 c.i.
Camshaft lift increased to take advantage of increased cylinder head flow.
Compression raised to 10.9:1
Larger, 90-mm single-blade throttle body
I think the intakes were LS6 models.
Cylinder heads for the LS2 are derived from designs used in previous Corvette Z06 models, including raised intake ports and an unshrouded-valve combustion chamber design.

LS2 GTO is 400 HP, Vette LS1 350 HP- Vette has the edge.If that GTO has some mods it will be a differant story. I ran up against a LS2 GTO last summer with my LS1 Vette with a few basic boltons and smoked it from a roll by many car lengths.

It takes alot more to get a GTO into the 11's than cam & intake. My supercharged (maggie) with catback, cai, custom tune would run mid 12's. Problem is hooking them up and terrible wheel hop, along with being heavy (close to 3900lb.). He probably had aleast 100 shot along with cam to be in 11's.

Most do have bad wheel hop..don't know what they do to stop it. One ran 11.8 and came out clean.

Plenty of guys are doing that. I personally know a guy running 12.1 with just pacesetter headers and on street tires. I'd suggest heading over to LS1gto.com if you doubt that. Now, I'll also be the first to admit that is freakishly low, and if I didn't know it's verified I'd be a little skeptical too. Point is, those GTO's are capable. How can you make a statement that cam and intake couldn't get a car into the 11's without knowing what kind of cam? The LS2 has a lot of potential.
The GTO can be put on a diet and lose 100lbs easily (yes I know that's not really stock), but it does suffer from bad wheel hop, one of the reasons that the Auto cars are actually faster in the 1/4 than the manual. A set of drag bags, or some suspension improvements can completely change the characteristics of the car.
I know a lot about the GTO, since one of my close friends and co-workers owns an 06. We spend a lot of time talking back and forth on the merits of each car and helping each other during upgrades. The C5 and the GTO are close in specs. Power/weight the C5 has a slight advantage.
But the real proof is in racing, and at several runs at Atco raceway, my C5 is a minimum of .7sec quicker than my friends GTO.
We both have no real power adders, other than CAI's and catbacks.
My best time 12.89.
His 13.6x.
But when his wheel-hop gets under control (and that may happen soon with his Harrop cover, and suspension upgrades), I know it will be a lot closer.

The 04 GTO's had 350hp LS1's. The 05-06 have 400hp LS2's. The manuals also come with the MN12 tranny (ala Z06). The cars are heavy, a good 400-500lbs more on a good day. They are also not a direct competitor, marketing wise. The vette is a sports car, the GTO is more of a touring car to compete with G35's and 3series BMW's. It's a completely different experience driving in one. It's a pretty soft ride with a quite interior. Not at all like the vette.

LOBOOST who hangs out in the FI/Nitrous Section has a fully built 364 LS2 APS TT 2005 GTO that has 770 rwhp and 775 rwtq. Looks completely stock.
