THE HEAVIER GTR USED RACE TIRES.

THE LIGHTER CORVETTE USED STOCK RUNFLATS.

You're an engineer. What will happen to the Nissan's lap time if it is on a comparable street tire to the Corvette's? Will the lap time increase by a large margin? Will there be little difference?

*HINT*
More real world data -
In testing my car, I found that race rubber is worth nearly 5 seconds a lap over street tires on a 40 SECOND AUTOCROSS COURSE.

 

No jg. Pete has retreated from that point. You now have ownership of it.

 

When you consider the length of the track even a 5 second difference is in the same ballpark.

 

Might also note the driver of the Z06 was Jan Magnusen of the C6R Pratt Miller team and no bum of a driver himself.

Just to note the new Turbo SS Cobalt did a 8:22.85 lap record for a FWD production car of it's size class on street tires and John Heinricy drving.

So this will be a good idea the Camaro SS should at least see respectable 7 min range unless you really expect Chevy to let a 4 Cylinder Cobal be faster?

7:60-7:75 sound about right or in the ball park once it runs

Like the ring or not but almost every car GM has set up there has been a very good handling car with the owners and press. Generaly if it handles good there it will handle good anywhere. At least that is what GM is saying. I tend to believe them since they know a little more than any of us.

 

I'd really like to see segment times as the ring is a good accounting of a car's abilities. There are segments of the 'ring where handling is the thing, and segments where HP is the thing.

Tire choice is huge at any roadcourse...particularly the nord course at the 'ring. Times set on rubber that will be the tire the car is sold with mean more to me than properly shaved and heat cycled R compound results.

 

 

The C6 ZO6 was set up there. The rear shock valving was dead wrong. This was brought up by owners and by the press. The valving was corrected a year after introduction. This wasn't really advertised for obvious reasons. The car is evidently much better in high speed transitions now.

A proper handling car is not guaranteed just because they tout "Tuned at the 'Ring".



I'm beginning to think you don't have enough personal experience to temper what you read.....

 

Well, who knows really.

First there are sooo many factors which might affect such a lap time, it would be hard to predict.

Secondly, don't underestimate how much effort GM has put into the Cobalt SS's powertrain and chassis developement to get those times. It was a serious effort.

Third, I'm not so sure about how important Nurburgring lap times will be to the target Camaro SS buyer. Probably not very I'd imagine.

 

7:60 and 7:75 would be 8:00 or 8:15 on my stopwatch...but maybe I'm missing something.

 

Sorry My goof I ment 7:50-8:15 lap times.

Also just please drop the 3900 LBS as it was my worse case only as I stated before. I fully expect around 3700lbs with a chance at 3650 [fingers crossed] in V6 form. But for those who expect 3100-3400 you had better make other plans as that is not going to happen and has been made clear to us.

This thread is getting old quick. I will just sum it up as I have my trust in
the guys with the Bow Ties. They will get it to the point that 95% will be fine with the final product and what ones that are not happy would never be no matter what they do. Some have expectations that go well beyond what is affordable, realisitic and of any benefit to the company as a whole.

GM's goal is to satisfy the majority and make money. If money is not made we would not have a new Camaro. It may never be perfect to some but it will be close enough for the majority of paying buyers. That is what counts.

But some know more than GM. Just like those who know how to remove the B pillar that GM can't and still meet the goals.

 

Actually, if GM can meet it weight target, it'll be quite abit lighter than that.

 

is anyone else curious on why such an involved poster asked such a n00b question?
