Questions for all the Car Gurus!!!!?




Rosie posi


Hey guys and gals,
I am trying to learn more about cars. And lets just say, I know next to nothing. I have learned a bit by surfing the web, but there is still a ton of information I would like to learn. Anyway, any information you could give me on the cars and what not would be awesome. and remember, I know next to nothing, so you may have to explain what "torque" and so forth means before you use it. Thanks a ton! You guys are the best!

Tell me a bit about this cars? What is unique about them and what enables me to tell them apart from other cars? Inside and outside.

Nissian R34 Skyline
McLaren
Saleen
Toyota Supra
Honda NSX
Nissian 350Z and 300zx
Audi TT
Viper
Mazda rx 7 and 8
Stingray
Koenigsegg CCX
(if you cant or dont want to do all of them thats fine)

What is torque?
What is GT?
What is turbo? (I know sort of, but how does it work?)
What is Nitrus? " "
What is supercharge?
What is a roll cage?

Basically anything you wanna tell me about cars would be great. Websites, pictures of you own car, or cars you only dream of would be awesome! thanks!
Haha. thanks all you contributors! In depth explanations are fine. And I do know, torque is not peeling out. lol
anyway, I will look those cars up. I know how the basic engine works, intake of fuel and air through the camshaft into the engine where it is compressed then explodes and eventually causing the crankshaft to create a rotary motion that spins your tires. I know what carbon fiber is. I know the difference between a lambo mercialogo and gallardo. and how both are ridiculously expensive and dangerous. I know a good friend of mine loves his 300zx but wants a r34 skyline. I know people have a strange facination for supras and nsx's. I know the SSC Ultimate Aero is the fastest car in the world. I know I love riding in fast cars, and the feeling of going over 140 mph. Anything else you feel like sharing would be great. in depth or no. thanks guys :)



Answer
What is torque? Torque is essentially pulling power and/or acceleration off the line. The more torque you have, generally the better acceleration you have and the more weight you can carry/tow before the car starts to struggle. In imperial measurements, it's measured in pound-feet (lb-ft), and Newton metres (Nm) in metric.

What is GT? GT stands for Gran Turismo (translates from Italian to "Grand Touring"). These are top level sports luxury cars which usually have four seats and a front-engine, rear-wheel-drive configuration (where the engine is placed over the front wheels, and sends power to the rear wheels). These are things like Ferraris, Aston Martins, the Nissan Skyline GT-R, and Porsches.

What is a turbocharger? A turbocharger (Sometimes referred to as a "snail" due to the general shape of a turbo) is a device that increases the power of an engine by forcing more air into the engine, to sum it up briefly. Basically exhaust gases from the engine turn a fan (compressor) which draws in air and sends it into the "intake manifold" (which sends a mixture of fuel and air into the cylinders), resulting in more air being sent into the cylinders than a non-turbocharged car.

What is Nitrous? Nitrous Oxide (referred to by car fans as NOS, but more commonly known as the laughing gas used by dentists) is a chemical compound that forces more oxygen into the engine so it can burn more fuel and air. It acts as a temporary means of gaining a lot of power, on most systems you can see a temporary increase of 100 horsepower to the engine.

What is a supercharger? A supercharger is simply another way of doing a turbochargers job. Superchargers are driven by the engine as opposed to the turbocharger which uses exhaust gases emitted by the engine, but they increase power to the engine in a similar manner, ie. by sending more air into the cylinders.

What is a roll cage? A roll cage is a set of metal supports that are bolted into the interior of a car to increase rigidity/stiffness. They're mainly designed for racing cars to improve safety in the event of a rollover, but they also reduce body-roll and in general stiffen the car up so it can corner better and with more precision.

I will explain a few of the cars and why they are famous as well:

Nissan Skyline (R34 generation): The R34 Skyline is one of the most famous incarnations of the Skyline badge. It was developed in 1998-2002 and is probably most famous as a boy-racer's wet dream. Incredibly quick for what it had, but relatively cheap as well. However, they are very rare in America as they were not officially sold there and imports have stopped. They command quite a price tag now.

McLaren F1: Made in 1994, this was famous for being the fastest production car in the world, which was an award it held until 2005 when the Koenigsegg CCR beat it by a mere 1km/h.

Saleen: Saleen is an American tuning and supercar company that is most famous for its work on the Ford Mustangs and its Saleen S7 Twin Turbo supercar.

Toyota Supra: The Supra was a very legendary Japanese sports car. The JZA80, the last generation of it, is the most famous and regarded as one of the best Japanese sports cars in history.

Honda NSX: Commonly referred to as the Japanese Ferrari, this is widely regarded as one of Japan's only "real" supercars. Like the Skyline, it was cheap but very quick for its specifications, and not to mention it wasn't a bad looker either.

Nissan 300ZX, 350Z: The 300ZX was built in two generations and predominantly as a luxury car which is what the "X" in its name designated. This trend was started by the 300ZX's predecessor, the 280ZX. The 300ZX had two major trim levels: the Fairlady Z and the 2+2. The Fairlady Z was a 2-seater coupe whereas the 2+2 had two very small seats in the back row for some added practicality. Both versions had the option of non-turbo, single-turbo on the first generation (Z31), and twin-turbo on the second generation (Z32). The 350Z was the successor to the 300ZX and focussed more on sportiness rather than luxury. It had a larger motor than the 300ZX (although the twin-turbo versions of the 300ZX were actually faster), completely brand new styling and two major trims: Track and Touring.

Audi TT: The TT is a 2-door 2-seat coupe that was designed primarily as a sports-luxury car.

Dodge Viper: The Dodge Viper was first developed as a roadster in the late 80's where it became commonly known as the "Boulevard Dragster", mainly because it couldn't really take corners that well but had a huge amount of power on tap which gave it incredible straight-line performance. Now though the Viper SRT10 is an accomplished sports car that actually has the dynamic ability to back up that monstrous 8.4L V10 engine.

Mazda RX-7 and RX-8: These are mainly only unique because of their engines, which were "Wankel" rotaries, which did not use pistons like a normal car would; instead they used rotors, which got them the name rotaries.

Stingray: A trim level for the early generation Chevrolet Corvettes. The two most famous Stingrays are the C2 (1963-67) and the C3 (1969-78).

Koenigsegg CCX: A Swedish-built hypercar capable of a top speed of about 250mph. The CCX was the successor to the CCR which was the first car to finally knock the McLaren F1 off of its fastest production car perch.

And here's a few of my own little things thrown in:

My own car:

I have a 1988 Nissan Skyline GXE with a few sound system trinkets thrown in. I'm going to throw some modifications on it soon but for now otherwise it's stock as a rock, with 271,000kms/168,000miles on the clock, and a 3.0L inline-6 putting out about 155hp (pretty weak now but it was good back in '88).

My current reasonably priced dream car is a 2004-05 Subaru Impreza WRX, much like the picture below, which was my mum's old example of this model car. All-wheel-drive, a 2.0L turbocharged flat-4 engine with a computer and exhaust system upgrade as well as new springs and a new set of wheels.

Your top ten sports and racing cars?




Barzillai





Answer
10. Porsche 917/30 - in terms of sheer power and dominance it would rank much higher on this list... but run for just 1973 pushes it down quite a bit. But would have to be on any list of best race cars, which is why it just nudged ahead of so many other deserving entries for the tenth spot.

9. Chaparral 2J - another dominant Can Am car. Very inventive even if this particular avenue for downforce is forever lost in modern regulations.

8. Auto Union C V16 - when looking at the sheer power of these old cars, and the amount of rubber they drove on, one has to seriously wonder just how brave (insane) those drivers were.

7. Porsche 908/3 - a hard choice, including this but not the 917k! Both shared the same basic chassis design (although in different scale). The 908/3's lightweight, nimbleness, and success at the punishing Nordschleife give it the edge.

6. 1962 Keith Black Top Fuel Dragster - driven by Don Prudhomme, this car racked up a record 236 wins (only 7 losses). As the single winningest car in pro racing, it has to be on the list!

5. Mclaren MP4/4 - 15 of 16 races were wins. The last and the best of the turbo F1 cars!

4. Jaguar C-Type - fast and beautiful. Images of these racing down the Mulsanne straight are among the most iconic images in motorsports.

3. Audi R8 - a new version of the old Silver Arrows? Successful and beautiful and massively ahead of the competition.

2. Ferrari F2002 - very successful, but much more than a minor evolution from the F2001. Some major advances and a car that would form the basis for the next two very successful Ferrari efforts.

1. Porsche 956/962 - hard to argue with that much success! And over a period spanning more than 10 years! An easy choice for number 1.

Car Racing?

Hey, i'm upgrading myself for my belove bf.he is a car racer.i want to learn more about car racing and street racing.where can i get those article??


Answer
Try magazines. Here are some of the websites for my favorite ones that cater to different sorts of racing:

Grassroots Motorsports http://www.grassrootsmotorsports.com/ Covers ammatuer road racing, rally racing, and autocross. One of the more "serious" magazines - it gives a lot of ink to real race cars instead of show cars.

Sport Compact Car http://www.sportcompactcarweb.com/ A magazine that mostly covers imports, with a lot of good technical information.

Car Craft http://www.carcraft.com Focuses on American V8 power and going fast on a low budget. Probably one of the most overtly about street racing.

Sometimes magazines will overhype things - I've tried to present some of the more hype-free ones, but even so, the cars there often are built by pros who know what they are doing, and home-built efforts to copy them sometimes fall short. I'd suggest paying a few visits in person to the local dragstrip. There you'll get to see how fast cars are in the real world - anybody who thinks his cold air intake and exhaust will give him 60 more horsepower is going to find out just what they really are good for when the light turns green.
