C7 Z06, Gone in 2.95 Seconds!

Actually they do, as well as giving better traction, they reduce rolling resistance. Haven't seen a car do 130+mph without slicks yet and no magazine has gone below mid-11s as far as I know.

 

Not my experience. Trap speed does not vary much at all. Getting out of the hole quickly will not change that. Who cares about mag results. I am looking at what people who own these things are doing and there will be plenty more coming now that the weather is getting better across the country.

 

Here is some proof for you. Notice the guys who posted stock times and then times with drag radials only. Kyle on the list had less than a 1mph difference put picked up 3tenths.The C6 ZR1 1/4 Mile and Standing Mile Fast List - Corvette Forum

 

Not on road legal tyres it won't no, which is why no Z06 on stock tyres has trapped more than 130mph and so far the most impressive times/speeds have come from people running on faster strips with the maximum permissible downhill slope. More representative magazine tests have been low-mid-11s and mid-120s. A 991 GT3 is faster from 0-150mph, see C&D test. It's a slow, heavy RWD car with a manual shift that puts in fast lap times because it has really sticky tyres, either that or it's magic, because that's the only other way it can be faster on track than lighter, faster MR cars with DCT.

One-off quarter times by owners are anything but representative (and also lack verification of stock status). People are well aware of the 'faster' drag strips. Here's a 10.27@136 from a stock 12C.

Always the tire excuse. Geez I'll put Cup 2's on a Primus and go out and break records.

 

Let's just stop with referring to magazine testing as the gold standard of accuracy. As someone that's been involved with a number of magazine comparos, I can state that they are anything but objective or accurate. They are simply rough estimates of a car's performance-that's it. Unless you have a group of cars together on the same day with perfectly controlled conditions(same time of day), a driver that is familiar with all of the cars(and not under contract with one of the manufacturers) and high confidence that each car is in fine fettle(not a well worn press car)-mag testing is nothing more than a wet finger in the wind.

 

Indeed. The Z06 is hardly slow.

 

These are not standard Cup 2s, not that standard Cup 2s are any slouch - 2.4s faster than Cup+ on a Turbo S around Jerez.

ForzaV12 - Well okay, but if we take dubious homemade drag strip claims, then every car is a half second and a few mph faster, as I've shown. Some strips are faster than others and home made runs are usually one direction only, which introduces a huge wind variable on top speed.

 

Seriously? You are suggesting that we have bi-directional drag runs to compensate for wind conditions? Maybe on 7mi long tracks that conduct high speed runs but for a 1/4mi? It appears you are blurring the lines between drag racing and road racing which you cannot do.

 

The only valid comparison is cars at same strip same day, same tires. Then you still have driver vraiations. Even if you use the same driver some are btter in some cars than others.

Variations though from run to run or lap to lap should be consistent.

None of which means that a semi pro race drive/amatuer tatoo artist can replicate any of the pro times. For sure amateurs are going to be quicker in more elctronic nanny cars, than more viceral cars, simply because the machine compesates so much and an mateur does not have the seat time to extract max performance from an less electronic nanny car.

Therefore the question may be if 4 or 5 cars are in the same genral performance ballpark, what is the best car for you? Do you drag, do you track, do you drive street, do you drive mountains, do you want manual, feedback etc. Do you nwat to be able to max a car at your skill level, or do you wnat always too mch car with nannies to inetrvene as yo hopefully grow.

The "fatest" car on a strip or track can be seriously lacking if you have other uses in mind, an all rounder may be too bland on street, some cars may be just right.

No question if the Z07 is on song, its pretty much the fastest street car out there street strip or track(other than maybe some ridiculous academic speed over 200). How many laps it can sustain vis a vis a GT3 and how pelasurable it is to drive, rewading feedback and whether its style and execution(layout) work for you, thosee to me the big factors. raw perofrmnce for afew laps, its so good, really the differences to another car(pick any street car) are so minor for an amateur as to be irrelevant.

A "lesser" car like a GT4 may be for many more rewarding to drive and use, for otehrs the rawness of a viper is the thing, and for soem the vette has it all. Some may go for a aventador at 4x the price and less performance.

At this point in development, performance of so many cars is so high, I woudl think other factors in terms of use and experiene sougfht may take more precedance.

 

Magazine drivers are professionals. If they can't get near 130+mph traps, it means the car is slower than other cars that do. The Z06 is an 11s 120s car 99.9% of the time. The other 0.1% nobody cares about.

I read on a nother forum that when most of the z06's run low trap speed, they might be in a high downforce configuration. But for lmfao and his conspiracy about whenever a Mac doesn't win, the other team is always cheating.

 

The Z06 is a track focused car, not a drag focused car. There is a (significant) difference. I wish people would understand that.

 

Go look at all of the posts on the Corvette forum, and then compare that with Rennlist. The Corvette demographic posts frequently on dragstrip times, and videos of cars pulling one another, something that you will never see on rennlist with respect to the GT3. I think the simple fact is that the Corvette demographic and buyer is very heavily interested in dragracing and straight-line performance. As a result, GM had to put lots of horsepower at the expense of weight and cooling capacity in the car.

 

good point but at least that means gm listens to what its buyers want something you cant say about too many car companies

 

Look at the reality of driving int he USA. Most cities are strips with stoplight to stoplight grands prix. Most drivers couldnt handle a street circut. There are also prtty draconian speed limits and strong enforcement. Hard to go over 80 most places. So for most drivers its about Tq, accleration to 60 and 1/4 mile. The cars are built to serve that and look good.

Makes me wonder about Gt3 drivers in the usa too. How many of those go to the track, i mean whats the point of a gt3 for most buyers.

Imo the perfect high performance car for most US street conditions is a hellcat challenger.

Still GM proved its chops with the previous z06 which was also light. Now we have more weight compensated by HP, the tires the tires, who will pray for the tires.


If we are going to have track laptimes as a factor is tests, lets see what 10 or 20 lap averages are, as well as consumable for a day at the track.

 

not so sure that kind of endurance testing for track/street cars is so pertinent. anyone who drives so hard that brakes and tires need changing every weekend will need a trailer. once need a trailer, why not just get a race car like Ferrari challenge or Porsche cup? they are less expensive than street versions, faster, and have all the safety equipment. or at least just strip out the street versions, put in cage/seats, and slicks/suspension.

most de drivers have fast cars like m4, vette, gtr, gt3, etc and go to track few times a year to get a feel for what they can do and enjoy the amusement park thrills. not a serious endeavor with telemetry and coaching to trim off last few hundredths per lap

 

Between those two poles lays a 3rd type of use. Go to nubering or any trackday and see how a number of people drive. Even if the car arrives on a trailer fior tires,t he rest should hild up.
The reason for a multi lap spec, is we would egt better cars, and it might put an end to a ridiculous hp race of no purpose, all papered over with nannies, and supported by ver escalating weight and runnign costs.
Track laps by definition are multiples, thats the spec not single.

 

been/driven ring. lots of track prepped gt3s and then the light weight like ariel atom type things. whats significance of that?

 

You know an Atom is not a serious car in any forum right, unless its top gear thirll.

 

This might help a bit more

you could say it's a car focused on creating drag though... certainly looks like appearance was a priority for the C7Z06. It looks great but functionally it's very questionable with the barn-door-sized gurney flap and lack of aero design for the underside. Still, I hope they get around to correcting it to make it the car I thought it would be.

 

Well you need drag for cornering.

The McLaren F1 has 627hp and goes 243.1 mph (drag limited).

The McLaren F1 LM has 680hp, weighs over 200 pounds less and goes 195mph (drag limited). Guess which is faster around a track?
