C6 1/4 Mile Performance Challenge




Yup, and that is the reason that many of the modded cars do not run crazy fast times



The purpose of this thread was basically to see who could post the fastest bone stock times. As CF members went to the track and posted their times the list evolved. We though that it would be challenging to get really fast times with stock rubber, hence the title "Stock Rubber" on the list.
Somewhere along the line we then added individuals who had modded their cars so that other CF members could benefit from each others experience as long as they ran their cars with the stock tires. The list allows CF members to actually see what performance gains are actully possible running stock tires.
I hope this answers your question

Also FWIW as far as bone stock Z06s and the 11s.
There are 6 C5 Z06s listed on this board as having run below 12.0 seconds BONE STOCK. The Top Forum BONE STOCK C5 Z06s:
Vai.................11.781 @ xxx.xx--xx/xx---Bone Stock
J-Rod............ 11.783 @ 116.90--xx/xx--Bone Stock ('02)
Ranger..........11.818 @ 117.26--xx/xx--Bone Stock ('02)
Esoteric.........11.93x @ 119.xx--xx/xx---Bone Stock
GMHTP..........11.97x @ 118.80--03/04--Bone Stock ('04)
02 Z06 Racer..11.99x @ 117.61--xx/xx--Bone Stock ('02)
These are all reported on street tires. Out of the top 6 on that list, that very top one, came under "moderate to intense" scrutiny by some in the Z06 community when it was first posted both here and in Z06vette.com.
A search of both sites shows that among some, who themselves are among the quickest C5 Z06s, on the list kept here http://forums.corvetteforum.com/show....php?t=1132866 opinions were voiced with regard to that very top time of 11.781 listed as completely bone stock.

Great info. dude!
Definitely better times with 18" drag radials. I just believe that 18" would turn faster while going through 1/4 mile giving the C6 at least .1 to .2 sec quicker and 1 to 2mph better trap speed. Our C6 definitely has the potentail.

Lets see what the new season brings and maybe someone will break the 12.40's
Lets see what the new season brings and maybe someone will break the 12.40's
No doubt the incidence of rear end breakage will go up with the use of drag radials and also ET streets. One should bear in mind that a lot of C5 rear ends, clutches, half shafts, etc, were sacrificed in the pursuit of making that C5 Z06 list. This is a point which is too often forgotten.

just got my '06 Z51 MN6 recently and will be heading to ennis,tx. after a 'reasonable' breakin period to get a time slip.
also, I believe the '06's got an upgraded rearend. can anyone expand on that?
Paul
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 think the magazine you may be referring to is the Sept 2005 "Corvette Enthusiast". Maybe that's not the article to which you are referring but it does discuss torque management. The article was about Cartec's C6 buildup. Here are some quotes:
"Torque management is a logic that was first developed for automatic transmission applications and is widely used throughtout the industry, not just in Corvettes. The theory is based on evoking a great deal of ignition retard just as the automatic transmission enters its shift sequence.
......Interestingly, the C6 is equipped with a torque management algorithm that is evoked not only on automatic transmission equipped cars , but six speed manual versions such as the Cartek Corvette. According to what was discovered by Cartek, the torque management logic not only retards the ignition timing but closes the throttle plate even though the the driver has the gas pedal matted. What was further ascertained is this logic is apparent during any drag-strip-style launch and power shifting between gears. This now explains the bog that was felt by Busch when driving the car at the track, and why less aggressive roll-out starts on the street felt stronger.
......A Cartek line lock kit was in place and with a 4500 rpm launch, the weak link and the reason for the torque management algorithm was discovered. The output shaft from the differential to the constant velocity joint and rear end case shattered. With a Cartek heavy duty output shaft installed, the car returned to the track and recorded a blistering 11.536/118.23 breathing through a factory air filter and air intake assembly."

Seems like you hit it on the nose, dude! You are exactly right about torque management. My tuner advised that as soon as they received the software, they will be working with the torque management also. The C6 has a slightly bigger engine, so for that reason it should have more torque. Another thing that you mentioned was about the weak transmission on the 05 C6. I have a 05 C6 so that's going to be an issue for me also.
Most C6 at the track in the Florida area are getting pretty good times. Good drivers are in the area of 12.5 - 13.1 with MN6. And auto 12.9 - 13.3 respectively.
And the very last thing you mentioned was about the C6 running 11.53@118mph. I believe that I have a video on that particular red car. The video was recorded in Nov 2004 and it went 11.58@116 on that pass. Everybody on this forum is curious on what mods this car has. And, it seems like you know some of the particulars. If you could disclose any further info. on this car, we would most certainly appreciate it. Thanks

A few things. First the original post which was quoted and included the statement:
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)...
If this was indeed the Cartek car then the chronicles can be followed in the postings of Dave_Busch.
If you do a search of his started threads, it is very easy to follow the development of his car if this is the car which Laron was referring to.
Follow the posts in this thread by Laron. He speaks of "them" breaking the rear following the removal of torque management. And "trannies were breaking all over the country " which of course was inaccurate. If he is trying to use that Cartek car as an example, then the record should be set straight.
http://forums.corvetteforum.com/show..._id=101&arch=1
The guy comes out and says that he got severe wheel hop on the 1-2 shift. Severe wheel hop will kill any rear end.
Busch started that thread following this one:
http://forums.corvetteforum.com/show..._id=101&arch=1
At that time by his account his mods were "My current mods are, 160 Tstat, Cartek fan controller, Kook’s 1 ¾” headers, high flow cats, 3.90 gears, HD output shaft, MT 17x11.5o ET Streets, Cartek line lock, Cartek torque management elimination module and temporary mufflers.
http://forums.corvetteforum.com/showthread.php?t=920254
This thread discusses the mods as well and the fact that they were running drag radials. "The current mods are Kooks longtube headers with high flow cats, 160 degree thermostat, and Cartek fan controller."
So as to Laron and his statement, it would appear that his chronology is off a bit. And it should shock no one that wheel hop, running drag radials, running ET Streets on a car making more than stock power would sooner or later cause a rear end failure.
Wheel hop will do it on stock tires. But they say they were runnning DRs when the rear went.
A car with its torque management removed making above stock power and on drag radials and finally ET Streets, breaking its drivetrain. Imagine that.

I've never been to a racetrack, never run a quarter mile and in all likelihood I never will, as I have no interest. I really have no interest in how fast this car or that compare to one another in the quarter. But to all the racers out there good luck and enjoy!
