yes stock for stock the shelby owns it. zl1 comes in at 12.4 while shelby is comming in at 11.9. nice cars though

 

I find that hard to believe when it's SAE certified at 650 at the flywheel!

 

it's sae certified at 662 at the flywheel.

 

Nice cannot wait to see the new numbers

 

Those numbers seem low, or is it just me?

 

This is an automatic car. The manual ones are making around 510 rwhp. This is pretty much in line with the CTS-V with the same engine in them.

Numbers are not bad. I find it interesting that the Zl1 supercharger whine is way louder than the Zr1.

 

With just a pulley, tune, and converter these cars will be way ahead of a 13 gt500 at the track. I watched several new 500s run on Saturday at Tulsa Raceway Park and I honestly wasnt impressed. The best pass I witnessed was 12.6 at 118. Nowhere near the magazine's times. Everyone keeps complaining about the z but theres definatley an advantage to the automatic when it comes to modding. I realize there are shops that can get 9 second passes out of them but the average driver sure can't.

 

team Ford has the same advantage with swapping pulleys too, though

 

Time to add some "Juice" to the mix.

Either Meth/H2O or N2O.

 

But they can't swap converters

 

no need.

 

For the factory rating of 580hp flywheel 484rwhp seems right in line for a A6. I just wish GM had given the LSA motor all forged internals. I think that would have made the CTS-V and ZL1 Camaro have even more potential since you could push 20PSI+ at it with a good tune. I hope they learn from this in their future supercharged motors.

 

great numbers...

 

with pulley tune and bolt ons guys have gone 9s @140+ in the 2013 gt500s

 

I think it would have been better if GM brought out a new engine for the ZL1...Being the same as the CTSV is kind of a turn-off...

If I had the cash to buy a ZL1 and then mod it? I would have got the ZR1 instead.

That vette would put a nice little whooping on the ZL1

 

My point is that the Z has an advantage over the GT500 since you can install a torque converter. The GT500s were having a hard time at the track last week. When you pulley and tune them, they will be even harder to modulate during take off. Yes I realize you can pulley and tune a GT500 as well. I just dont think an auto ZL1 is at as much of a disadvantage against the 500 as most on here on the track.

 

a tune netted 50 more horses


anyways...one raced an 06 z06 and won by about a length. its still too heavy...took 170 more horses to barely beat one. and an 06 at that. wish i had that video.

 

that mustang that made 609 rwhp is the only stang i've seen that has made that power...i'm seeing a lot of them getting baselined around 570-580 which is still extremely impressive. the ZL1 is a pretty nice car and is putting down real impressive times at the track for a stock car. i do agree with most, the next camaro that comes out will be a lot lighter and might make for a "better" car for the performance. however, the camaros are selling like crazy so at least GM did something right for this car.

 

there's been more than just one reported over 600whp.
