Ls3 a little underrated
Ls3 a little underrated My brother has a 08 c6 ls3 A6. All he has done is a hp tune. We were out last night and an 08 Viper GTS pulls up. We B.S. for a while then we decide to go hook them up. Granted he wasn't the best at launching it was a good race. From a 25 mph roll the viper only pulled about 1-2 lengths to 150 mph. Then from a dig they were even to 20 then the vette pulled 1-2 lengths on the viper to 150 mph. I would have to say if the ls3 keeps up with the viper the Zo6 LS7 has to eat its lunch. It was a fun night. Thought I would share with you all.

I ran my bone stock 2009 LS3 A6 the other night and got a personal best of 12.159@115.59. She only had 1300 miles on her and I am just learning how to drive her. These cars have a lot of power!
If these LS3s could launch comparable to their 1/4 mph they would be 11 second cars. Many are running close to 120 mph in the 1/4 mile in good air. The problem is torque management pulls out timing to negative at launch. Additionally they come with a very tight converter. They don't reach peak torque at launch until right at 30 mph. As a comparision my 98 Camaro with a PI 3600 stall reached peak torque around 5 mph.
Ya we know the guy. And ya when we tuned the vette we took out all torque management and it was night and day difference. It scratches the tires on the 1-2 and 2-3 shift. My brother ran it once before the tune and it ran a 12.35 @115.3mph @ 2600 ft DA. So at sea level it would be 11's for sure.

Ya I know this isn't my first rodeo. We removed all torque reduction tables. Max torque table is set to 700+ ft lbs. AFR is leaned out some. Spark tables modified. The works. I have been tuning with hp for a few years.

no bickering fellow LS1techies! it's all good the LS3 really impresses me as much as my LS1 does! I was hoping to look intho a LS3 motor and tranny swap for my WS6 I wonder what the LS3 will do with long tube headers,Xpipe and catback with a 3600-4000 stall??? and then a nice nasty cam?

The LS3 is unbelievable. I added full exhaust, CAI, and a tune and got the same horsepower as my Big Cam, Full Exhaust, CAI, Tune LS2 GTO. Plus I got about 40rwtq more than the LS2.
Plus they are so light! I saw a post where the owner did a few weight reduction mods and the car weighed a little over 3150lbs.
I can't wait to run into a new Viper or Porsche.

Did not mean any disrespect it was more of a sarcastic statement. Im's sorry if you took offense to my statement. But yes I was aware of all the tables. Yes the LS3's are runners as you can see in my sig I run a 13.1 and my bro pulls me like there is no tomorrow. I love ls based motors, to me it doesn't get any better then these things.
Viper police present.
No such thing as an SRT-10 "GTS". They quit calling them GTS back in Gen II (pre-03).
SRT-10 coupe started in '06. These typically run 11.9-12.1 stock, trap around 118-119 mph. Mostly due to crappy gearing (3.08 ratio) and 3400 lb weight. In 2008, they became 600 hp. These 08+ coupes are running low 11s at 128-129 mph. A stock C6 would get raped by an '08+ Viper in the hands of a decent driver.
I'm betting you ran an '06 coupe, as they perform very close to an LS3 Corvette. Either that, or the Viper driver was a pansy with limp wrists.

I am not sure I believe he said gts but I don't know. It looks just like your sig pic of the viper. I know it is an 08. It said 2008 on his 30 day tag. And he told us it was 600 horse. Also I looked at motortrend and for the 2008 viper 600 horse They only had it at 11.7 @ 125. But who knows. I do know he said his gear ratio was a 2.72. If that helps. I don't know a lot about dodge Sorry. Let me know what you think it was All I know is it was an 08. Thanks

Ya I'm not sure what ratio it has. The guy doesn't know to much about it and Yes he was a terrible driver. He also said that it had 600 horse and 600+ torque and it only has like 500+ torque. Is there any way to tell what engine it has? And rear gears? But The vette did kill it off the line. If motortrend only tested it at a 11.7 at sea level and we are at 2500+ ft DA. I could see him only running a 12.2-12.3 here. Plus a bad driver is more like mid to high 12's. His launch style was like a 3k drop and tire smoke. Non the less it was fun.
LS3 C6s are no joke.
