Why Is A C5 Fast Than A Trans Am

I can't believe I am replying to this, but... I had a '99 Camaro with only a lid and catback, It ran 12.0's all day, and it was a 6 speed. I beat many stock Vettes in that car, and when you are talking about a couple of tenths, a driver can make that up in a number of ways. Either car spinning a car length off the line makes the difference. Internet racing is just that, and I am sure that most of us have had experiences with F-bodies, mustangs, and even turbo'd benz's that would surprise you. The reason the Vette is faster stock is because it is a VETTE and Chevrolet wouldn't have it otherwise, but the second you get out of the stock realm, things change dramatically.
I cant believe Im replying to your reply that you can believe your replying too. So, you ran 12.00 with a factory Z-28? I would like to see that timeslip........

To me a t/a is about equal. I've been 13.10@107mph all stock driving a friends car. 2nd pass in the car. With headers only, no tune, on stock tires I have been 12.79@110mph

I ran my vette at the track on test and tune day against my buddy. He had a 2002 Z28 with headers and a stall. I had headers also. We ran like 4 times and the outcome was the same on every run, nose to nose at the finish. So really I think they run about the same stock to stock. Now my ws6 is a little differant story..

I'm gonna go with gear ratio. Or do they have the same gears in the trannys and rear ends?
No jokes about trannys and rear ends.

Somebody correct me if I'm wrong but automatic vette will have the 2.73 and the Z51 has the 3.15. The M6 vette has the 3.42. Auto F bodys are a 3.23 while the M6 is 3.42

Heh. The "average" weight for a LS1 F-body is 3500 lbs when you look at both ends of the spectrum from "stripper" Z28/Formulas to loaded 'vert WS6s.
The early Vettes did indeed have a slightly different cam, but it was negligible at best. A LS1 is a LS1 is a LS1.
The Corvette has a slightly better exhaust, but that is offset by the IRS, so both cars will dyno the same, or with the Vette slightly lower.
M6 gearing is the same between the two, but A4 Vettes offered 2.73s or 3.15s, while A4 F-bodys had 2.73s or 3.23s.
As pointed out earlier, the main advantages the Vettes has is weight and aerodynamics. The weight will usually offset the IRS out of the hole and the aero will shine at the top of the track. This is why Corvettes may not always get a better time, but will usually have a higher trap.
The LS1 F-body may not be as much of a sports-car as a C5, but they are a cheap, reliable platform that can do many things well and are ridiculously easy/relatively inexpensive to make fast.

Not sure what your getting at here Tim?
I have the highest respect for Mr. AU N EGL, but are you implying that it's more reliable to weigh other people's cars...........or your own???
Since I've weighed MY cars, on the same scale at the same day, right after one another, with both about 1/2 tank of gas, and know exactly what has been done to each...............that would be more unreliable than seeing other cars getting weighed (with no clue what's really been done to them)????
A look at GM's factory curb weight numbers (which are illegal to incorrectly file with the NTHSA for weights) agree with me. Does anyone need me to post the exact GVW numbers right off my door panels??? This is just plain stupid, as there's only been around a 350lb difference in true stock form. Options will affect than number slightly, but only by a few lbs. A stock WS6 came with pretty much every option already in it, so that's your top number.
I have no doubt that he's seen 3700lbs F-bodies, what he may not have seen was the roll cage, iron block, and full upgraded suspensions.

I remember Car and Driver ran a 13.4 with a stock 2001 Camaro SS.. I think the best for the 99 6sp C5 was 13.2 or 13.3 cant remember which,, Any how it boils down to a drivers race.. The F body 6 speeds will take a C5 A4 with stock 2.73 gears for sure

Let's keep the comparrison stock for stock. You guys start posting about CAI intakes, cat-backs and headers and that changes everything.
All I'll say is, I've owned both (in six speeds) and the 2 cars are VERY close. The LS1 motor is the same in both cars.
You guys will be debating this until the end of time
This is like trying to convince a Democrat to be a Republican and vs a vs
