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 ass kicking (as we know you are), you need to look a little harder.

yeah that was my friend and I. We agreed that I should get the hit because we both expected his z06 to pull on me so that only seemed fair.

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 balls

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

Are we looking at the same video? At higher speed, the C7 was pulling the C6... Watch it again

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.

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....

^^^ zackly

I'd give up on that. It's been pointed out probably a dozen times by now (at least twice by me), but it doesn't seem to register.

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.

You're probably right. Math is hard.

3,523# vs. 3,130# = 2% heavier

650 Hp vs. 505 Hp = 29% more horsepower.

More pesky math.

Added:

650 lb/ft vs 470 lb/ft = 28% more torque. Definitely needs a bigger supercharger. So anemic...

But you don't understand... the C6 is just... FASTER... somehow... :rofl:

Bottom line is no matter what numbers we put down, people are gonna be like "but I seent it on da youtubes!"

I fixed a typo. It's 29% more horsepower.

As I mentioned in a previous post in this thread, not too many Zs in my area, but you have my word that the next time I come across one, I'll do a race and make a video if I have to hold the guy at gun point

If you go fully loaded, 3LZ/Z07, absolutely. 1LZ and 2LZ are going to be lighter.

Regardless, 12% doesn't get you to 28% more torque and 29% more horsepower.

Nope. And I tried to simplify it by putting raw power:weight ratio, but apparently that ain't good enough either.

bahaha. well played sir

Why don't you just sell your C7Z and get a C6Z? I just don't understand the constant complaining, negative comments, etc.

I'm confused. Who's unhappy with their C7?

As suspected!
 

Just another GIZMO thread who ran around with no liquid in the intercoolers.

I owned 2 of both cars. Chonger is correct!

Mr gizmo all he does is complain abut the C7 and how great the C6 is. His post really are pure garbage not sure why he bothers. Sell it and move on.

I love my car. But I also cant wait for the c8 so i can upgrade.

gm didnt go backwards with the Corvette. Each generation it got better. The c8 will be epic. I cant wait.

Ah, nope. You're definitely wrong. Owned an 09 C6Z, now own an A8 C7Z. Based on personal, recorded numbers across many scenarios, the C7Z wins, consistently, due to published/factual power advantages.

Sorry that Miss Piggy continues to annoy you. Time to call the divorce lawyers and move on.

Not sure why you don't join the Maggy 2300 club pm me and I'll tell you where you get one for 4400 shipped.
Last one only took 2 weeks to get here Buy my plane ticket and fly me and we can put it on in one day with two working.
Macth my mods maybe even use my tune???
Post your new style 1.7 for 2k and call it a day and your complaints will change to love when you smack down a Demon on the interstate.

it seams like the c7 wound up slowly.was it a z or a gs?my car does not wind up like that,it winds up faster.

Read first sentence, scrolled to end to say:
Odds of stock C6Z slim, and if it was true, it'd be slower, so sorry not biting today!

Things we know to be true:

Earth is flat
Flu shots give you the flu
C6Z is faster than the C7Z
Vaccines give you autism
chemtrails
new world order
hitler and elvis are alive
moon landing didn't happen

don't forget the moon landing was a hoax (though I suppose that falls in the realm of earth is flat)

I included some 1500 rpm speeds.

C6 Z06 speed at redline (7000 rpm)

C7 Z06 speeds at redline (6500 rpm)


C7 Z06 186 mph top speed is with aero 3. Should be 195 -> 200 mph with aero 1.

Yea you would think folks could tell the difference between a GS and a Z06. LOL
Sad Attempt to troll us I guess. Really sad.

Uh oh, did you run out of Midol?

Hugh? I agreed with your observation the C7 in the video is a GS not a Z06.
And you respond with an insult?

Perhaps you misunderstood my complement?

Apparently so. My apologies. :cheers:

Not a Z06?
you guys are funny.
its my best friends car. 2017 z06.
We were just having fun. Not trying to upset the masses.

One of the dumbest threads in a while, but not surprising given who started it.

Ok cool...perhaps he changed the taillights to red in color and removed the red from the Z06 badges on the fender.
I didn't think of that.

We arent upset, just having fun with the nonsense.
But seriously trying to logically justify why a 650 hp car would lose ground to a car with 145 hp less in a roll on race.
The laws of physics say it aint so. Unless the C6 is modified?

Yeah she is!!!!!!

NP, happens to the best of us.

Did you notice at freeze frame 23 seconds in video the C7Z's brake lights are on including the 3rd brake light?
At freeze frame 48 seconds the brake lights are all off including the 3rd brake light. Yet they are still red!
I thought Z06 taillights where white?

Let me guess, he swapped out the tail lights and blacked out the fender badges to bait folks into roll racing a Z06.

LOL.

Look. I can post videos too.. bolton C6Z vs stock C7Z. Not same outcome as your race.


in your race the c6z given the hit each time. 1 second hit from roll takes alot to reel in near equal match. But it will.

c7z needs driver mod. Even with horrible driving the C7Z WITH stage IiI aero gaining anyway. Clear as day.

short shift 5800 2nd vid.


I mean we can go on and on. But that video is not representative of what a C7Z does. Not for the M7..


especially not an A8.

ps. If you thought it was an A8 C7Z you would be wrong. And he also had a passenger AND short shifted the hell out of it and it still caught the C6Z with ease. An A8 wpuld have destroyed the C6Z here.

The GS really held its own!

lol.. you mean REELED the C6Z in. Which btw is tuned has LTs and a bigger throttle body and driven wel with each gear run out? vs the stock short shifted C7Z woth Stage II aero on?

I know you hate your Z06. Why not go BACK to your C6Z? It's insane this self hating attitude toward a far superior model of the same car.

didnt even start @ same time... :lol:

Disable the features you don't want on your OnStar account.

What a poor way to represent the c7z.

I think the c7z owner was sandbagging big time. That or hes scared of his car. That's 75% of its straight line performance you saw from the c7z.

but a win is a win. It didnt prove much though.

I thought they gathered all that info to cover up that 9/11 was an inside job?

On a more serious note, I'm not sure how GM would collect any data if you don't have Onstar, and even if they did, there is 0 chance they could sell your data for that much. To put it in perspective, your ENTIRE Facebook profile (as in your ENTIRE LIFE, not just what you do for an hour a week in your car) is worth all of about 20 bucks. If you need documentation, here's just one of many results of a google search that back this data up https://adage.com/article/digital/wo...google/293042/. Feel like this is derailing the thread a bit, but since it has become just a flame fest anyway, figured it didn't matter.

You keep basing your conclusion on the first published Car and Driver time for 0-150 for the C7 Z06.
That time has been debunked as flawed.

Look at the many 1 mile runs or 1.5 mile runs posted by several car clubs when they rent airports or close roads (ie the Texas mile).
Stock C7Z's run neck and neck with stock ZR1's.

So unless you are suggesting the C6 Z06 runs head to head with a C6 ZR1? Please give it a rest.

Looks like the lights where on therefore the taillights would be red so my original assertion may have been wrong.
Still no explanation for the gold tag in the video and the white tag in the photos. Could be the same car, but maybe not.
So the benefit of the doubt goes to the Op.

Regardless, unless the C6Z is modified the C7Z is quicker.

Giz, congrats on starting another shit storm! Paul

The photo shows a white tag because that's a NJ temp plate/tag.

Gold tag is the official NJ license plate.

Either or i think the C7Z owner still is getting used to his car. When i first got my car, even well after the 500 mile break in, i didn't go WOT. It was too scary. Especially in 1st or 2nd gear. 3rd and 4th gear i would ease my foot into it, maybe giving 75% throttle.

Only since a year ago have i experienced full throttle in my Z lol. I love the 3rd to 4th gear WOT pulls. My favorite.

Once that C7Z owner learns his car and isn't scared as much, he should re-run his friends C6Z. It'll be a different outcome. Maybe by not much though since he has a full aero kit it seems, which slows down the car dramatically.

A stage 1 manual Z should eat this C6Z.

So most of your complaining about "miss piggy" being slow, was due to you being afraid to push the throttle down all the way? :lolg:

Road & Track performance data for the C7 Z06 notes the Z07 option reduces top speed by 9 mph, from 195 mph to 186 mph. I assume that is aero stage 3 versus aero stage 1.

The C7 Z06 has about a 15% power to weight advantage (including driver). The C6 Z06 has a top speed of 198 mph, in 5th gear at 6300 rpm, the rpm of peak horsepower. The C7 Z06 M7 redlines at 186 mph in 5th gear, while 186 mph in 6th gear is 5400 rpm, and 195 mph at 5661 rpm, both below the 6400 rpm of peak power, so the C7 Z06 M7 is not geared for top speed. The C7 Z06 M7 redlines in 4th gear at 150 mph, so that should help in a 0 to 150 mph run. Ignoring drive train losses, power is proportional to speed^3. Based on this assumption, at 100 mph the C6 Z06 is losing about 12.9% of it's power to drag, while the C7 Z06 is losing about 15.5% of it's power to drag, reducing the C7 Z06's remaining power to weight advantage to about 14.5%. At 150 mph, the C6 Z06 is losing about 43.5% of it's peak power to drag, while the C7 Z06 is losing about 52.4% of it's peak power to drag, reducing it's power to weight advantage to about 12.6%, but that's still an advantage for the C7 Z06.

0 to 60 is traction limited on both cars, so it depends on the tires, and I recall something like 3.4 seconds for the C6 and 3.1 for the C7 (manual). Some C6 owners switched to Nitto NT05's which may have as much grip as the MPSS tires on the C7 Z06, but that's speculation. I've seen a range of numbers for 0 to 150 mph, with one source reporting 17.7 for the C6 versus 17.1 for the C7 (I don't recall the source). Acceleration times web site has much slower numbers, like 22.8 C6 versus 22.5 C7, versus 18.6 C6 ZR1.

There's also the issue of the A8, which is faster for 0 to 100 mph (traction limited to around 60 mph, is the A8 just a bit smoother in getting the power down to the pavement?), but once at 100 mph, the C7 Z06 is well beyond it's traction limits, and the A8's consumption of power, should result in slower 100 mph to 150 mph time versus the M7.

On the 7:13.90 20.6 km "lap" at Nordschleife, the C7 Z06 topped out around 174 mph (280 kph) at 7:40 into the video below. I don't know if this was a heat issue causing timing to be pulled a bit.

No because the OP has miss piggy but could why the Conti's has the better grip! :rolleyes:

lol time to take your meds.

You're referring to Mr gizmo calling his car miss piggy. Not me.

Lol you cant even get your own argument right lmao

anddddddd bingo. Finally someone understands.

What? Rob G isn't a shortened version of Rob Gizmo? ;)

Lol dont change the subject. You slipped up. Might wanna work on your memory haha

What memory? Who are you? What's this about? Thank God it's Friday! :rock: :lol:

Lol that's what I figured.

Stage 3 aero w/ the Z07 package. Stage 1 aero is light years faster up top.

Here is my post from another thread from the Zr1 section, which i believe a few in this thread commented in as well.

Both cars are stock. The c6z is a 2013 and the c7z is a manual 2017 stage 1 aero

​​​​​​

The back straight at the Nordschleife, Döttinger Höhe, is slightly uphill and pretty exposed to headwinds (moreso than most of the rest of the track), so that might play a minor role as well.

LOL.

You guys keep ignoring the fact that in the first run (at freeze frame 41 seconds) the C7Z activated traction control because it was spinning.
Game should have been over at that point but the 7Z was reeling the 6Z in anyway before they knocked it off at 125ish mph.

In the second pull the 7Z starts in 3rd gear at 54ish mph (freeze frame 1:07). He should have gone to 2nd like he did in the first pull.
No reason whatsoever to start a roll race in third at 56 mph in the 7Z. Think about it, 1st is good for over 60 mph, second is good for over 90 mph.
Why are we starting a race in third when theoretically we are within a hair of being able to go to 1st? (I am exaggerating here to make the point).

Bottom line is the first pull is disqualified because traction control pulled throttle for at least 2 seconds. (any of you that have hit TC before know exactly what I mean here).
The second pull is disqualified because the driver (unintentionally or otherwise) started the race in the wrong gear (3rd instead of 2nd).

So there are a few conclusions we can draw from this...... but one of them aint.....a 7Z is slower than a 6Z. LOL.

:hide: :thumbs: :lurk:

I'm surprised people still give Gizmo the time of day. He's a complete troll yet people bite every time...

lol you'd be surprised at how easy it is to bait people.

come on -- give me a break. I am not a troll. I have had a c4zr1, c6z06, and now a c7z06 we call Miss Piggy. Just putting a little healthy debate out there for all us prideful C7Z06 owners that are proud of the 650/650 badge on the console.

Even had a C2 and a 1990 c4 with an L98 with a whopping 225hp(What a dog that thing was) Stock -5.0 mustangs of the day would blow the doors off that thing back in the day.

The 1990 C4 L98 was 245 or 250 HP and it was absolutely quicker than a stock 220 HP 5.0L Mustang. I guess some people just love to hate on what they own.

honestly I think I know what his deal is.

he actually loves his car. But maybe where he lives or the people he hangs out with hates his car. So what he does is play that role of hate online in order to inherit any defense made for the car that he can use in his personal life.

he might not have known all the "facts" about the c7z vs the c6z so in order to get those facts so he can use it in real life, he has to play the villian here.

idk lol.
