It really doesn’t matter now does it? I suspect that the Z06 will outperform the ZL1 in every performance measure. In regards to dyno comparisons there are so many variables weather, shop temperature, dyno itself, belt/strap tension, operator, that any small difference should not be considered an advantage or disadvantage but more wishful thinking.

It'll be interesting to see. The ZL1 will benefit in the 1/4 mile from lower drag than a Z06, a more modern transmission, possibly slightly higher power, and the latest rev software.

Possibly, but the top dog Corvette will not be outperformed by the top Camaro.

Well the bigger SC lid like the 5th gen ZL1 was worth 20/30hp more putting the 6th gen @ 660-670hp I vote for the ZL1

[BlackinBlack]

My guess is they will be close to the same HP on paper with the ZL1 having slightly more real world.

The Corvette has bigger rear tires. 335 vs 305. The non Z07 tire is the Pilot SS and are very sticky. I had a Gen 5 ZL1 with around 600 hp and the Goodyears NEVER stuck like the MPSS do on my Z06.

Finally it will be power to weight. The Stingray weighs 3300 lbs. The Z06 weighs 3550 lbs. So the LT4 and other upgrades are 250 lbs on the car. This is after all the carbon fiber bits to make it lighter. This makes the car 5.36 lbs per hp.

The SS Camaro weighs 3750. Add the same 250 lbs on the car you get 4000 lbs. Which is my guess on the new ZL1 wieght. Even with 670 hp you get 5.97 lbs per hp. With 650 it is 6.15 lbs per hp. To equal the Z06 power to weigh it would need 746 hp which will not happen.

Also the 2016 Camaro is currently 54% front and 46% rear which I am guessing will be about the same in the ZL1. (Most ZL1 weigh add is in the front but betting GM will be moving some to the back to balance out like they did last time.)

Corvette Z06 is a perfect 50/50 so more rear weight on the tires.

Current record for a 100% stock non Z07 Z06 is 10.4 so the MPSS really put the power down.



BTW the car was in Aero 3 setup in the rear so higher drag. Bet the MPH could have been higher with the Aero 1 setup. But I would not be surprised if the ZL1 had a ton of drag too. The Gen 5 cars did. Downforce = drag but also handling.

My bet is the ZL1 will be a solid 11 sec car all stock with well driven auto examples pushing the 10s.

In all fairness that is not really a factual statement. After all we appear to be comparing the incoming ZL1 to the older Corvette. If on the other hand the 2017 C7 were already available or had some announcement already this might be more suitable. While I believe we can all agree that the Vette is the performance flagship in Chevys product line there's no reason why the new ZL1 cannot have more advertised horsepower than the 2016 Z06. The OP appears to be posing a hypothetical question in general. We can't simply accept one time slip or one Dyno pull as definitive evidence. It's probably more prudent to wait however I doubt anyone expected 640 as a number when the older ZL1 had roughly 580. For all we know the Vette can eclipse 680 or more so I doubt the engineers are worried about a glass ceiling. Somewhere there must be a memo that reads Thou shalt not produce blah blah blah. I just can't find it right now.

What's "rev software"?

rev = "revision of" software

Still waiting to see the specs on the 2017 Z06. I suspect it will have improved cooling (like the new ZL1) and tweaked to push out more power than the 2016 Z06 model.

The OP wants to know what we think will happen ... ie, our guesses and opinions based on past knowledge and experience.

Read the post, not just the title

Do you have past knowledge or experience with the gen 6 ZL1?

Don't forget, the supercharger is physically bigger than the z06. Is it because it has a larger plenum? Or is it larger than 1.7L? Most likely just the plenum, but they would get a lot of good press if they went bigger.

Corvette does not keep the Camaro down, plus there may be a zr1 coming.

The blower/intake is bigger on the zl1? How do we know that?

[tones2SS]

I'm going to guess the ZL1 will be putting down more rwhp, just because I think the ZL1 will be packing more power and torque. Not much more, but a little more.

[Sven59]

I think with the optional drag radials on the ZL1 drag strip edition will make the difference.
