Thanks for the proof read.

 

OK, my friend has been after me to take the C6 to the track, which in his vernacular, is the dragstrip.

While the C6 has seen some pretty extensive time out at Texas World Speedway, it's never seen a dragstrip. For that matter, neither have I. I came up driving very small, very low horsepower, very nimble sports cars, so while I learned a ton about road racing and autocrossing, there wasn't much point in going to the strip.

I think I'm going to go, but I have no clue what I'm doing out there. What are some pointers? I think the thing I'm going to have the most problem with is the launch, as you almost never get to do this on a road course. Powershifting I can do, and I know when to shift, and I know to turn the AH/TC off. I know to watch for wheelhop, and I saw the bit about powershifting 2-3 and 4-5.

 

These would be more meaningful if all details were known .. weather, track etc.

 

Mine were at Texas Motorplex Ennis,Texas 55-60 degrees

 

My time was poste at Lebanon Valley Dragway, NY.

In September I ran my C6 at Beech Bend in Bowling Green,KY, not a very good track. This was my first time out with the Vette. I only run at the track two or three times a year with my 02 Camaro SS. I turned a 12.7@114 with a 2.12 60'. Now don't forget Iam 71 years old. Mods are in my sig.

 

Okay, we won't tell anyone that with your years of "experience" you should be able to beat us all

 

And your car is a completely stock C6? That doesn't seem to make much sense. The Z06's are a little lighter, have a little better top end, and with those mods, likely 30-35rwhp more than you. I can't imagine the pull would be that slow, unless you are simply outdriving them.

 

The car I did it in was bone stock with 250 miles on it (yes, I know I did not break it in right!). Both of these folks are good friends of mine, and both will attest to what I'm telling you. And one of them is definitely a very good driver. We have both gone head-to-head at the drag strip and autocrossing in comparable cars before. We are very evenly matched drivers.

We ran from 55 - 120mph. Up to 90 we were side by side (look at the torque curves of the two cars and you'll know why). From there to 120 he pulled about 2 car lengths on me, at most.

 

Actually you are saying he has 385rwhp, well thats a good 35 to 45rwhp difference, plus he has an intake? Which one? If its a vararam, these results don't even really show on the dyno, yet many have seen up to 3mph increase in the 1/4 b/c at speed the vram really makes a big difference. So at speed he could realistically have 50-60+rwhp on you AND is about 100lbs lighter, and you guys have the same gearing. If he only pulled 2 CL's from 55-120....IMO, you definitely are the better driver

PS-You'd have to look at the Tq curve of his car as is with the mods and it should be at least as good as the C6.

 

No, they do not have Vararams. Yes, their torque curves are at least as good as the C6- that's why I didn't pull them at any time. Their 35 extra hp comes into play at higher rpm - which is where they pulled me. I can assure you it was not driver - if it was, I would only be pulling them on the shifts.

Jim, I was told at the factory that the average LS2 dynos at 428 horsepower. Your track results against those Z06s seem to support that figure. The non-believers might want to consider that.

 

What was the humidity? From what I have been able to garner, during the time that you were there 10/19 the humidity in that area never went above 68%. Is this accurate?

 

EB2003...

I apologized for any offense.....But please remember that when you talk about my track time of 13.5 at 103 mph stock at my track that it is a very good time for my track....

The fastest stock Z06 has only went 12.7 at 111 or 112...Most dont break out of the 13's.

So my LS6 times of 13.1 at 106 mph is actualy right on par with the Z06's at my track stock for stock....That 13.1 is killing the fastest stock Cobra by a solid 3 tenths....

Now Im trapping 108 mph untuned with the 224/224...My car is defiently in the 12's....If I was at one of your tracks in the mainland where stock Z06's run 12.4's (or better) Id be in the low 12's...

So please dont dismiss my car....345 rwhp before the 224/224 cam with the stock LS6 H/C and Vararam is actualy pretty impressive for a 2004 automatic...

They typicaly dyno 290 rwhp so even before my cam I was a solid 55 rwhp above stock.

Now since people posted that I wasnt offending them Ill state my opinion once more.....

IM PROUD THAT THERE ARE A FEW C6'S RUNNING 12.4-12.6 BONE STOCK....

Atleaste that lets me know that pound for pound a C6 CAN out perform a 03 Cobra....Im very happy about that...

But what your showing is the best of the best.....

For example I could easily post a list of stock C5's that have ran 12.6-12.9 bone stock.....

I could easily post the list of Z06's that have ran high 11's-12.0 bone stock....

They would be no different than your list of C6's running 12.4-12.7 Bone stock...

HOWEVER THERES A PROBLEM WITH THESE LIST...

They are in no way the norm......

The bottom line is this....

The Typical Z06 is gonna run 12.6 at 113 mph

The typical C6 is gonna run 13.1 at 109 mph

The typical C5 is gonna run 13.4 at 107 mph


Now Ive read post of stock Z06's trapping 117.....And stock C6's trapping 114...And stock C5's trapping 111....

But lets just be for real....

Theres a reason that the fastest Z06's are in the 11.8 range and that the C6's are in the 12.4 range...

The Z06 is the faster car.....Just think about it for one second.....

THE QUICKEST TIMES POSTED ON THIS FORUM FOR THE C6 IS A 12.4...

THAT 12.4 IS EXACTLY WHAT 1 OUT OF EVERY 10 GUYS WHO DRIVES A Z06 CAN ACHIEVE....AND SOME OF THEM EVEN HIT 12.3 OR BETTER BONE STOCK...

WERE TALKING 1 OUT OF EVERY 10 VRS ALL THE C6 OWNERS ON THIS FORUM....

12.4 VRS 11.8.....IS SOMEONE REALLY GONNA SQUEEZE ANOTHER 6 TENTHS OUT OF A STOCK C6?

If you totaly disagree then please explain why.....But dont use tire sizes or track prep or weather conditions....The Z06's run at the same tracks as you...

As for my opinion on TM....I first started researching it when I read a article on a C6 in a Chevy magazine...

These professional guys were hoping for mid 12's at 112 or so and could only get 13.1 at 107-109 with a 0-60 mph of only 4.7..

They quoted that these were stock C5 times and were upset with the results....

They dynoed the C6 and saw that it was making around 350rwhp....

They were confused....They then removed the TM and went back to the same track and ran a 12.4 at 113 ( I beleave) with a 0-60 of 4.3...

Unfortunetly the trannie/rear (I forget) blew after only a few passes without the TM...They then quoted that this is why GM put so much TM in the production models.....The rear is a week link...

So they put in a stronger rear with some DR's and an Intake and ran an high 11 at 115 mph ( I beleave)...

I read this and then later low and behold I started reading of 90% of people not getting below 13.0 and quite a few busted rears....

With the TM removed it is a great contender to the Z06....It will only be giving up 5-10 rwhp....

With the TM it's typically gonna be a good 4 tenths slower....

I know some of you read this same article.......And I know that most of you agree that you dont see many C6's break 13.0...Even with good drivers on prepped tracks.

EB2003...I dont mean to offend you...Im just stating my opinion on what Ive read and seen.....I love corvettes period and would love for all C6's to hit around 12.7 bone stock....But it just hasnt been that way....I wish it had but it hasnt.

Go to other vehicle forums and see there opinions of the C6....Most post up how it didnt beat 13.2 or 13.1....They still respect it but they arent scared.....Then check out there post on the stock Z06 than ran 12.6......They worship the ground it walks on....

In the main land stock SRT-4's can run 14.0-14.5

EVos and STI's can run 13.4-13.9

Cobras can run 12.8-13.3

05 stangs can run 13.7-14.2

Just a short list of what these cars can run on average

Now throw in the C6's typical 12.9-13.4

YEA IT'S FAST.....BUT THE OTHERS ARE RIGHT THERE READY TO POUNCE..

Now look at the typical numbers people see a Z06 run...12.5-13.0

It's slowest time is basicly everyone elses quickest times....

Im sorry...But GM just made the 02 Z06 to fast......I just read an article in car and driver on the 06 Viper hard top..

They got it to run 12.5 at 117 mph and were comparing it to the C6Z06...I just laughed to myself and thought of how according to their numbers it would have a hard time to beat a 2004 Z06...

Thats just how awesome the Z06 is guys.

 

I am not as offended as you might think Laron. I enjoy a good debate.
BTW, the quickest bone stock Z06s in my area run in the 12.3-12.4 range.

A few questions for you however. You said:

Since the 02-04 Z06 and the 05-06 MN6 Z51 C6 are very similar in power and gearing, to what do you attribute the performance difference?

There are a few differences. I know you don't like this. but it has already been pointed out, the tires. The approx 100lb weight difference is negligable unless you are talking about very good drivers. And then there is "Torque Management"/ and "Launch Control."

I'd bet that you will find that the typical Z06 driver is a better drag racer than the typical C6 driver is as well. Many people who buy the Z06 are coming over from other performance cars and will continue to race. Most C6s will never see the track.

A huge factor that you are overlooking is the fact that many of those guys who are driving the Z06 into the 11s, have not had a chance to do the same with the Z51 MN6. In our camp we have no drivers with the skill of a J-Rod or a Ranger. Many of us are just ordinary and less than ordinary drivers.

I wonder what would happen if Evan Smith, J-Rod, Ranger, Dr. Ron.........If you have been here any length of time you know the driving skills of the last three are well above average. Us.........we are just ordinary guys with skills that pale in comparison to these guys.

It is very doubtful that if you put a MN6 Z51 C6 in the hands of one of those guys that you would see the same times that many of us run. The mid to high 12s.

Another important point about that list. There are some 30 names on the top of that list. I believe that there were over 10,000-11,000 2002-2004 Z06 made. I believe they were making about 3500 a year. What percentage of Z06 drivers do you think that list represents?

Finally, the official GM numbers in the quarter mile seperate the 2 cars by 1 tenth in the quarter mile.

 

I'm just waiting on a 50 degree day on a sea level track with the sun out a 30.40 berometer no head wind, or a 30 mph tail wind. A track thats been prepped for promods and one of those bad boy just melting his tires right in front of me. You guys are going to be toast!

 

Here are my times...it was my first time to the track. I need work on my lauch but here it is:

Z-51 6 spd. - Only mods - Bassani cat back:

R/T- .172
60- 2.190
330- 5.715
1/8- 8.560
MPH- 87.44
1000- 10.964
1/4- 12.994
MPH- 111.25

Here's a link to a video recap of the day that I edited together...My girlfriend shot the track video. My best race was the 3rd.

Nice runs get that 60' down to 2.00 and you'll be running 12.50-60. Enjoyed the video.
