Stage 1 Aero VS C6 ZR1
Stage 1 aero A8 vs C6 ZR1
Which one is faster in stright line acceleration up to top speed?
I will leave this video here
Lamborghini Huracán LP 610-4 (610 HP) vs McLaren 650S Spider (650 HP (0-186mph)
No way the new C7Z will beat those cars!

ZR1 has a higher top speed.
Pretty likely the ZR would reach the new Z's top speed, before the new Z does, given the aero drag of the Z's downforce bits.
1/4 mile will go the Z. 1/2 mile to the ZR with the cars fairly close. 1 mile the ZR will be walking away (and walking away the whole second 1/2 mile), and would continue to do so until top end.
Put 'em both on a road course and the ZR probably staring at the Zs tail the whole time.

C7Z has better gearing and more HP/turque. the weight has less effect in high speed acceleration especially with +45 lb-ft than the ZR1.

Maybe. I'm a regular miler, and I'll certainly find out with mine (and I'll be unbolting the stage 2 rear spoiler. Will keep the front splitter - I run my ZR with the front splitter, and it actually helps keep the nose planted at speed - and when running 180, that is a good thing).
I expect my new Z to run mid 170. My ZR is a 180+ car.
I think the new Z has enough additional drag, and will have on the second half higher IATs pulling timing, I'll be surprised if it can hit 180 in a mile.
But we'll see.
I agree on the weight - pretty much a non-issue up top.

The 2013 ZR1 reaches 205 MPH in 5th gear at 6290 RPM with its final gear ratio of 2.43.
The C7 Z06 A8 reaches 205 MPH in 6th gear at 6250 RPM with it's final gear ratio of 2.41. Slight advantage to the ZR1 with it's lower gearing(greater torque multiplication) but is offset by the C7 Z06 with it's greater engine torque. If, in fact, the C7 Z06 has to punch a larger hole in the air, it stands to reason, it won't be able to hit 205 MPH top speed.
In the standing mile, both cars are in the same gear as when they hit their top speed, but the ZR1 is having to accelerate less weight than the C7 Z06.
Now lets look at the "other" ZR1, the original version and the newer verison with the PDE Option, with it's different transmission gearing.
At 180 MPH in the standing mile, the ZR1 with PDE is at 6360 RPM with a final gear ratio of 2.80. Compare that to the C7 Z06 A8 at 180 MPH at 5465 RPM with a final gear ratio of 2.41. Gearing advantage goes to the ZR1 and we need to compare the LT4's horsepower/torque at 5465 RPM vs the LS9's horsepower/torque at 6360 RPM.
LS9 at 6360 RPM is ~630 HP with ~ 600 lb-ft. 600 lb-ft(at the flywheel) X 2.80 final gearing = 1680 lb-ft to the axles.
LT4 at 5465 RPM is ~600 HP with ~ 595 lb-ft. 595 lb-ft(at the flywheel) x 2.41 final gearing = 1434 lb-ft to the axles.
Looks as if the ZR1 PDE has the better gearing in the standing mile and should have a higher speed.

I got a feeling we are going to see allot of C6 ZR1 Vs C7 Zo6 roll races on the net soon, just like we did with C4 ZR1 vs C5 Zo6. Stock for stock in top speed runs the C4 Zr1's always came out on top. I cant wait to see what happens this time.

As much as I know the ZR1's average speed is around 178mph

And I agree with the C6Z speed. I ran one for years. Those are solid high 160, low 170 cars stock, and with just intake, tune and exhaust low/mid 170s quite repeatedly. Those cars respond quite well to just simple/modest mods for the mile.
Just don't see the new Z hitting 180 in the mile. But if it does it'll put an even bigger smile on my face than I'll already probably have with it.

Aero drag is .35 for both the 2013 C6 ZR1 and the C7 Z06 A8 base, so it depends on which car has the smallest frontal area. I bet the ZR1 has the smallest frontal area.
The 2013 ZR1 reaches 205 MPH in 5th gear at 6290 RPM with its final gear ratio of 2.43.
The C7 Z06 A8 reaches 205 MPH in 6th gear at 6250 RPM with it's final gear ratio of 2.41. Slight advantage to the ZR1 with it's lower gearing(greater torque multiplication).

The wight is compansated by the extra HP/Torque.

Yeah, that's what I expect to see out of it (mid 170s). I will be pleasantly surprised if it's higher. 10% more efficient intercooler dealing with that huffer spinning at 20k rpm will push IAT's on the back half.
And I agree with the C6Z speed. I ran one for years. Those are solid high 160, low 170 cars stock, and with just intake, tune and exhaust low/mid 170s quite repeatedly. Those cars respond quite well to just simple/modest mods for the mile.

The 2013 base ZR1 has a fifth gear ratio of .71 and multiplied by the differential 3.42 =2.43.
The 2013 base ZR1 hits it top speed in 5th gear.
Only the original ZR1 and the later ZR1 with the PDE option hits it's top speed in 6th gear(.68) and multiplied by it's 3.42 differential ratio of 3.42 = 2.33.
The base C7 ZR1 A8 hits it's top speed in 6th gear(1.00:1) and multiplied by it's differential ratio of 2.41 = 2.41.
That means both of them have virtually identical final gear ratios when doing a top speed run(2.43 for the 2013 base ZR1 and 2.41 or the Z06 A8). The ZR1 has slight advantage in gearing on the top speed run along with the weight advantage, but the C7 Z06 has the horsepower an torque advantage.
Now for the mile run, the original ZR1(and the newer ZR1 with the PDE option) has the gearing advantage over the C7 Z06 with them both running in the 175-180 MPH range.
