now that we have made all of these suggestions i would agree that if you want to beat those cars a 350z is not the car to do it. i mean sure everything is possible but all of the stuff you would have to do to it would make it cost more than a viper.

 

go to preformance motorsport in westbury long island ny
there street tire drag car went 8.33 and it's deffinitely faster now.
they sell engine packages that you can finance up to $50,000

 

Age old question...............

The easiest/cheapest way find a cliff ... Mark out 20 FT before the cliff...repel the cliff and mark out a quatermile (free).... have a paving company pave a road to the end of the cliff, ofcourse off the main highway($3000) depending on their rates. Get the two retards out to a bar and boozed up pretty good (MAYBE $15 for the corvette guy)(prolly around $40 for the redneck in the rustang)Total:$55.
Get them to the marked out quarter mile cliff dragway. Be sure theres appox 20ft run to the cliff... (This is imparitive) Three honks "HONK"HONK"HONK". There you go.. The shear weight of the Z will garantee you the win between these two beasts and maybe even a 10 sec quater mile. Depending if you remembered to time it.

Total: $3050.. I just saved you 80k. Thank me later.

 

What do you wanna beat it in, looks? If so, you've already won.

 

With more power you would definately want a lower FD like the 3.3 in the 5AT. Even lower would be nice to reduce shifting and maximize top speed in the lower gears. Also, the stock suspension is way too stiff for drag racing which is another reason why traction is hard to come by. You would need an adjustable setup to allow the weight of the car to really transfer back onto the rear wheels to help them grab off the line. I don't even think TTs are necessary for 10s. A built up NA motor running a two stage nitrous setup with the proper fuel system and engine management would easily make enough power. The key from there is putting the power down with traction. Building the tranny and driveline would also need to be done. Of course a finely tuned TT system would be nice, but a lot more money as well.

 

U will need a 800hp beast

 

According to Road and Track the 06 Vette has:
Horsepower (SAE) 400 bhp @ 6000 rpm
Torque 400 lb-ft @ 4400 rpm
0-60 4.5 sec
Curb weight 3290 lb

Not sure how much power a supercharged vette is putting down, I'm guessing 500-550hp to the wheels? Looking at the data panel I see the vette has a weight distribution of 52/48 f/r, is running 245/40-18 front and 285/35-19 rear tires, has a 3.42:1 final drive ratio with:
Gear/Ratio/Overall
1/2.97/10.16
2/2.07/7.08
3/1.43/4.89
4/1.00/3.42
5/.71/2.43
6/.57/1.95

For comparison purposes, the 350Z gearing both stock and with 3.9FD is:
Looking at the ratios its clear the Vette will have a big advantage putting the power down. The 3.9FD is probably not a great idea in this scenario.

If you can figure out a way to stuff some wide tires under the 350Z (maybe buy a widebody kit), and put in a built motor with FI I think you could get into the 10's on street tires. You probably need to bump out the rear quarter panels about an inch to run 335 tires.

For comparison, the 911 Carrera S on the same data panel is running gearing similar to the stock Z and ran a 12.8 1/4, 355bhp from the factory, 295 rear tires. Granted its got the engine in the back, weight distribution is 40/60
