And I also just drove a 2011 auto ss and I was kinda dissapionted.

 

The automatic G8 is quicker than the manual. Same with the CTS-V. These aren't sportscars, they are heavy cruisers. It isn't even that much fun to bang the gears in the overweight Camaro.

 

so its not like giving the ole ws6 a famous ls1 first gear 30 punch huh?

 

weird, I read the autos dyno significatly lower though?

 

It's about damn time! Did you finally grow a set of nuts and decide to give it a good and hard launch?

All kidding aside, did you do anything to your car and did you post anywhere about getting into the 11's?

I think people finally got tired of seeing your beautiful car turn 12.0's @ 125 mph.

 

Greater drive train loss in an auto than a manual. I think manuals dyno about 10 rwhp greater than autos.

 

so the stock gxp says it makes 415 hp but only dynoed 338? Seems like alot of hp loss. But it seems it picked up tons of power with just headers, intake, and tune

 

My wife's stock M6 GXP ran a 8.7 on the 1/8th. It would be faster except it likes to wheel hop if I left at anything above idle.

 

The auto gxp vs the m6 gxp...the m6 will dyno about 30whp more but that doesn't make it quicker. The autos are more consistently running 12s in stock trim than the m6's are. It's all drivetrain loss. The thing about a g8...especially the GXP is the fact that if you catch one on a roll you may have a better race on your hands than the 1/4 et will lead you to believe. These cars weigh 4k lbs. It takes alot to get them out of the hole, but once they're moving, they're moving! My car goes almost 110mph to run a 12.9. Most cars run a better et with a 110mph trap. I've suprised a few people.

 

but from a roll a 6 speed with beat a auto and thats the kinda fun racing I do.

 

I agree to a point, I like rowing my own gears, but there's always the thought that a guy with the same car with less than or equal to mods and an auto will probably be faster.

Also, manual GXP's are almost impossible to find. I've seen only one, same with CTS-V's.

 

maybe faster in the 1/4 but not faster in a roll race

 

Is this an educated guess or an uneducated guess? I was just wondering if you have concrete information or just a gut feeling.

 

Well, with other cars this is the case. My 6 speed ws6 would always walk similar modded autos from a roll. Its the ability to drop a gear and keep the rpms up. With a manual the power is instant. With an auto you have to wait for the tranny to downshift before you start

 

Bill, throw all your automatic trans knowledge based on 4th gens out the window. The same logic we used on the A4 vs M6 arguments back then do not apply to the newer generation of 6-speed automatics.

The 6-speed autos have less parasitic drivetrain loss, better spaced gears to keep your engine in the correct powerband, more aggressive early gears to get the car moving, quicker shifts, etc...

These new cars are all independent rear axle, the auto trans helps greatly reduce any wheel hop, and the gearing/converter get them off the line better.

Roll racing them on the highway is about equal, based on my experience. The 6-spd auto downshifts perfectly and quickly.

 

hmm, guess I just have to go drive one

 

The A6 has the sport mode or whatever its called that you can put it in if you're worried about dowshifting.
I liked the way they felt when we test drove them. It was lightyears ahead of the TBSS that you could count to 10 after you floor it before it would downshift.

The biggest complaint I have about the M6 is where the clutch engages. Its too far up for my liking.

 

Just to clarify, those bone stock times in the earlier posts by Booster and Goat were with drag tires if I'm not mistaken. Correct me it I'm wrong.

Factory G8 powertrain quick summary:
G8: Who cares
G8 GT: 6.0L V8 (LS76) 361hp, auto only.
G8 GXP: 6.2L V8 (LS3 ?) 415hp, auto or M6.
G8 Firehawk: G8 GT with a supercharger 500hp

As for G8 autos at a roll, they such. I have to stomp it just before the second honk so the car will go after the third.

 

Doesn't the 1SS have a L76 or is it a L99 cant remember?

 

Yes, the automatic Camaro has an L99 which is a dod motor, very similar to the L76. Not sure the exact differences.

I ran my 12.9s on drag radials...in warm weather with a 2.0 60ft. I ran 13.0 in cool weather with a 1.9 60ft. Both at 109mph.
