New Member Puzzled
I am soon to be a Corvette owner again. Have previously owned an '84, '87, '95, and an' 02 all coupes. A C6 will be in my garage within a month. Many of you guys report 12.9-13.2 1/4 times. I understand variations in density altitude, VHT track prep differences, driver skill level etc. I just sold an '03 Cobra which ran consistent 12.9-13.0 on the factory F1's, no weight reduction. totaly bone stock, weghing over 3,700 lbs without driver in 80-90 degree weather. The Cobra is rated/stated @ 390 HP but known to be slightly underated for whatever reasons.
The C6 is roughly equal in HP and TQ and weighs less than 3,200 lbs. That is a huge difference when pondering performance stats. Is it the torque management system? That would be my 1st or best guess. There is something limiting here.

There is a lot of talk about torque management in the tech forum (here).
Here is one thread as an example:

Another comparison to consider is a CTS-V which seems to turn very low 13's at a 3,800+ curb weight. Is there a hand held tuner or other gizmo that anybody is aware of that will disable or negate the torque management. I wanna manage torque my way!

Believe what you like, but I ran a 12.5 at 115 in my bone stock six speed C6. I cannot go into details due to forum rules, but I can also tell you that my car is convincingly faster than a slightly modified Cobra from a variety of speeds, including a dead stop.
This whole issue of torque management is blown way out of proportion by a lot of people who have never even driven a C6. I have seen exactly one post by someone with a six speed C6 who took their car to the drag strip and was dissapointed in their time, and blamed it on torque management. I have a hard time getting concerned over one data point.
There have been more times posted for A4 cars, and they have varied quite a bit more. There has been more than one run 12.7, though.
Hope this helps.

The 03 Cobra which I sold a few days ago was in its mildly modified state, CAI, upper pulley swap, predator tune and Catback dynoing @ 462Rwhp and 487Rwtq and turnig 11.8 1/4's. The same setup with a better driver will consistently run a couple tenths faster. I will be pleased if I can match your 12.5 in my M6 C6.

not that I care.....
Was just browsing through the forum when I noticed and read your posts re: your 'tang and it's 1/4 mile times etc.
Your first post indicates it's relatively stock - "...an '03 Cobra which ran consistent 12.9-13.0 on the factory F1's, no weight reduction. totaly bone stock, weghing over 3,700 lbs without driver in 80-90 degree weather. The Cobra is rated/stated @ 390 HP but known to be slightly underated for whatever reasons. ..."
Then your last post reads - "...The 03 Cobra which I sold a few days ago was in its mildly modified state, CAI, upper pulley swap, predator tune and Catback dynoing @ 462Rwhp and 487Rwtq..."
IS there a "mis-print" here? Two different cars......?
Not being critical AT ALL...just curious as the differences in the "two" cars is a little confusing......NOW - not only are you, as - "Thread: New Member Puzzled" , now I am also....."Old Member Puzzled".

Having also owned a 03 cobra will tell everyone I don't miss the rear wheel hop. Hardest car I have ever owned to get out of the hole. The Vette is much easier to launch and my Lightning is even easier to launch. Having been to the track many time the easier a car is to get out of the hole the lower the resulting time becomes and the more effeciently you are at getting the horsepower to the ground. This results in higher trap and lower ET's.

mph trap speeds (one magazine and forum
members).
4-6 mph in the 1/4 mile sounds substantial to me
and indicates the power to weight advantage of the
C6 is real and is reflected in the numbers.

When are we going to get 3 mods for say $1,400 that will give us an extra 100 rwhp on a C6?

[QUOTE=dr.david]
It's all about the supercharger. Supercharged and turbocharged cars are relatively cheap and easy to get more horsepower out of because all you have to do is increase boost. On a supercharged car, it's a matter of changing pulleys. On a turbocharged car it is usually a matter of adjusting a "waste gate" to allow more boost (up to the point the system can put out).

If the GT500 can be as easily modded as the 03/04's, look out. I really don't care for what I see in that picture. Looks like a high school seniors dream car.
