Some Sport Car Questions?

Direct correlation between engine size and output horsepower?


"Yes, however, there are loads of other variables that affect output, i.e. valve timing, compression ratios, intake and exhaust, forced induction, etc. So we can have a 3.8L V6 that makes 180hp and a smaller 2L turbocharged flat four that makes 300hp.

Example, if you have two V8's, first with slightly more displacement, second with equal valve timing and breathing and all that other stuff, the bigger engine will be more powerful."


There's no rule, just averages, an average and most common bhp/litre figure, 2.0-litre petrol over here has about 140bhp, 1.8's having 120bhp, 1.6's having 100bhp and so on.


Difference of having nitrogen in your tires rather than oxygen?


Nitrogen leaks out of the tire more slowly, leading to less frequent air fill-ups, due to Nitrogen larger molecules than air. Nitrogen performs more consistant, due to Nitrogen less sensitive to temperature change.


Nitrogen has to deal with rubber oxidation as well as the diffusion/transfer of heat throughout the tire as a whole.. Nitrogen makes up 90 something % of the air, so if the tire leaks, the nitrogen doesnt diffuse as fast as other gases because the concentration is pretty much the same.


Pure nitrogen (at least almost 100%) is fine. Dont let ANYBODY put 100% oxygen in your tires. Fire LOVES oxygen.


Nitrogen filled tyre will have a more constant pressure, from cold through to operating optimal temperature, regardless of ambient temperature than an air filled tyre, reducing not only pressure "loss" or variation, but thus also reducing wear. It is also less "leak-able" than air from the tyre as well, reducing pressure loss over time.


"Technically we should use Nitrogen as it is better.

I have Summer and Winter tyres for my R32 both Nitrogen filled. When I fitted my Summer tyres after 4 months worth of storage, they had not lost a single pound of pressure. I used them all through Summer and checked them last week before storing them again. I had not lost a single pound in pressure. ie I have not had to adjust tyre pressures for two years!!!

what is torque


I have always seen torque as acceleration, and hp as velocity. The more torque you get in a car, the more G's you will feel per say, within traction. You can have a big hp car, which means your car can go up to a certain speed that the engine can handle. Torque is how fast you will get that speed, a car potentially needs more torque to get to faster speeds because of factors such as drag and aerodynamic proficiencies. This is how I've always seen it as.


"You can have a big hp car, which means your car can go up to a certain speed that the engine can handle...
not necessarily, its not what it can handle but what it produces, really its RPM that is related to what the engine can handle."


why do people hate the Bugatti Veyron again?


Bugatti Veyron can beat many supercars in the road


Bugatti Veyron looks a bit like a pot belly pig


Bugatti Veyron's overpriced, underengineered, understyled, and impractical, yet gets treated like a god in every car magazine, show, and site.


Bugatti Veyron is because the style of both cars suited the '90s


Difference between "F-body" and "Fox body"?


F bodies are the Camaros and Firebirds from GM. Fox body means the basic frame for the second, third and forth generation Mustangs.
