looks like a fair/safe heads up compare. stock c7z versus stock c6z. C7z gets easily pulled.

Are you sure that's a C7 Z06, and not a Grand Sport?

I thought the C6 jumped it a little and the C7 would have gone by him if the C6 didnt back out... I guess if you are hoping for a C7 *** kicking (as we know you are), you need to look a little harder.

you might have jumped a little. — very little. But as you got to higher speeds, he wasn’t keeping up. Eventually he would have needed binoculars to see the *** end of your c6z.

Well you started in 2nd at 34 mph. That's still 1st gear territory for the C7 Z. If you had started at say 50 or better yet, 60 in 2nd, the C7 would have pulled away easily. I've made that mistake before, starting in 2nd at a low speed roll. 2nd sucks at that rpm range. Edit: oh geez, just saw the 2nd race. started in 3rd at FIFTY??? jesus. you're not even at redline for 1st gear at 50. Why would you start in 3rd???

The C7Z's PDR data shows he started around 2600 RPM. Seems a little below the powerband and would explain the C6 gaining little distance at the beginning but the C7 starting to gain shortly after.

From wikipedia:
C6 - The Z06 weighed 3,130 lb (1,420 kg), giving it a weight to power ratio of 6.2 pounds per horsepower
C7- The Chevrolet Corvette Z06 has a power-to-weight ratio of 2.42 kg (5.34 lb) per horsepower.
Numbers ain't be lyin...
Sure, the C6 weighs about 400lbs less than the C7, but with 150 less hp and almost 200 fewer lb-ft torque, it just doesn't have the *****

If the c6z started in 1st, then it definitely would have had an advantage. only if it also started in 2nd would it neutralize the advantage. Also I don't know the gearing for the c6z, but i imagine it's shorter than the c7, so even if it started in 2nd, it would still be closer to the power band

I've raced a couple of C6 Zs and have never had an issue leaving them in the dust. There aren't too many Z06s in the area in general. I only know of 2 other C7 Zs. I don't have a large sample to compare to, but from my anecdotal experience and just straight up math, I can't support that being a legit race. Something wasn't right. Either the C6 wasn't stock, there was a problem with the C7, they started at an optimal rolling speed and shift point for the C6 (cuz they were both TERRIBLE points for the C7), or something else was going on. I just ain't buying it.

In the first race, you are definitely right (which supports my rollout speed theory), but in the 2nd race, the C6 starts ahead and just continues to pull away (again, supporting my rollout theory)

Same track, same tires, same driver, the C7 Z is faster. I have compared my times at Sebring in the two cars and average 4-5 seconds per lap faster in the C7. Straight speed going into turn 17 is a little lower in the C7 though.

yes. And it is clear at the higher speeds the c7z was gaining but it was gaining long after the c6z driver let off the gas. The c6z driver is on this thread. Maybe he and his friend can chime in on this

I'm not sure about about "being as equal as you can get" but I would think that driving each individual car to their full potential (IE at whatever speed/gear/rpm they are capable of the best acceleration) would be the only way to tell which one is actually quicker. I'm not sure why anyone would care who is faster in a certain gear since the gear ratio and engine powerbands are different between two different model cars....

The C6Z has recorded consistent 8.6 second 60-130 times and the C7Z is between 7.8 and 8.1 seconds depending on Auto/Manual.
Half a second is enough time for the C6Z to get the jump and maintain a lead as the C7Z had to then reel that other car in.
I raced a head cam FBO C6Z (~560whp) with a solid driver (in my A8 Z06) and he started to creep away but it wasn't a walk away situation.
