Faster is always better I agree but we've now seen some LS3 Vettes running low 12's and a 11 sec pass in stock trim. Per HOTCIVIC's digging. Those times don't seem like an underachievement to me.
What would you consider a respectable time for an LS3 Vette?

 

With their power to weight ratio, they should be above 114-115 more consistantly (auto's). The gearing really messes them up.

 

I didn't know that they didn't hit 114-115 on a consistant pace. Guess I've only read or heard about the manuals and they certainly do hit that speed if not more.

 

they do hit 114-115, but they should be more consistantly at 116+. Its that terrible rear end gear the auto's have that negates that great gearing the transmission has.

 

I take it you're not a fan of the 2.56. I can only surmise that GM wanted to give the A6 good low end acceleration around town hense the trans ratios being taller than those on the M6 but had to worry about fuel economy too. The M6 gets a rated 16/26 and the A6 gets 15/25. Had they stuck a 2.73, 3.07 or 3.23 in the back the mileage may have suffered. To that I would've said drop the ratios on the 5th and 6th gear overdrive. Maybe it wasn't an option.

It's interesting that GM has different trans ratios for the M6 in the Z51 C6 that almost match the 2010 SS and are different from the more normal ratios seen on the Z06/Standard C6. Those ratios have been the standard 6 speed ratios for the 4th gen's, 03-04 Cobra and C5's.

Without a doubt the 5th Gen will run high 12s M6 and A6

I will bet the A6 will out perform the M6 at the 1/4 drags. Gearing is a factor here people. Also ... look at the 425hp dodge that goes 13.1-13.2 at 4100 lbs. your SS will be 300-400 lbs lighter.

GM is conservative with it HP numbers the cars will have the same motors as the VETTES. Look back to the 4th gen Z28 vs. C5 vettes ... the auto 4th gens were running the best times with the 3.23 rears... even though the vette was lighter than the 4th gen camaro.

Also... look at the C6 vettes with A4 vs. the newer A6 6.0 vettes... the A6 vettes are .2-.3ths faster.

I have raced a few A6 6.2 vettes... although they had air intakes and tune. they run BOTTOM BOTTOM 12s to high high 11s with 115-117mph.

FACE it most guys cant drive a M6 as good as the writers from MT, C/D, R&T etc... we certainly can NOT out drive the pros. Only a few will be able to shift the M6 to the mid 12.5-12.4 range in a new 422HP SS 5th Gen. Most will only manage 12.9-12.8....

I bet the A6 SS will be the car to have for DRAG racing...

BTW... all you anti IRS drag race fans...

My cam only LS1 C3 with 3.23 and TH350 cut 1.7 60ft times with a FOOT BRAKE !! 12.2 @112

 

the hemi cars are ~200-240 lbs more than their equiv. counterpart.

and the 422hp LS3 will be SAE certified, so there won't be any "conservative" GM rating. that's all it will make in stock form.

OK so your saying NOW the 5th Gen Camaro weighs 3920?? Funny seems a little high for me. From what the general said.

SAE corrections asisde... do you think they will be a Difference in the MOTOR from a 6.2 in a C6 corvette, or 6.2 GTX G8, or Camaro SS? not talking exhaust systems.... strickly the motor??

 

nice CHARGER. based on information around, the CHALLENGER is said to weigh 4040-4140.

As for the LS3 available to the GXP and SS, i think will be the same as the corvette. But to get the power to the C6 (430-436 hp), it will mean it is modified.

 

these cars still have overall better gearing than the vette. even though the vette is lighter. the gearing will make up some distance for the light weight.

the cars will run 12s

 

c6s where never ever a4s. And C5s where not that much lighter than ls1s 4th gens... 200 lbs at most? Its not like now that we have a 600-700lb punishment.

 

No they dont, not the manual camaro's. The base corvette has basically the same horrid overally gearing while the Z51 is a little better than the manual camaro's.

The auto camaro's do have better gearing than the auto corvettes, but will suffer from both the weight issue AND a considerable less amount of power. The auto camaro will make up some distance on the manual camaro's though with that gearing, I completely agree with you on that.

 

well, they were A4's (LS2's), just never with the LS3.

 

No... they were A5s on 2005 (ls2) a6s with the ls2 on 2006 up.

 

in '05 they used the 4 speed 4L65-E, which is a revised version of the 4L60 for more tq and higher shift points.
