"THIS IS THE FASTEST CAR WE HAVE EVER TESTED.." THE WORLD RECORD CAR..http://www.gofastvideo.com/gallery/i...oenigsegg.html

Why isn't there much hype about this car? Who would win in a race..? This or the Bugatti Veyron?

or this?http://www.autoclips.net/detail.php?...&id_video=3328

the pagani zonda f? They should line these guys up.

Bugatti would win easily....

The Koenigsegg was faster than the Mclaren by 1 MPH (241MPH).
It broke the record before the Bugatti was released.

The Bugatti is limited to 253MPH.

by the time the Mclaren reaches 90MPH the Buggati would have hit 150MPH... I read that in motor trend.
The Mclaren is faster than the Zonda.

why does it say "torque is directly proportional to displacment" in your sig? that doesnt make any sense to me please explain? me and alot of my friends all have small motors with crazy torque.

[ACS3]

probably because your cars are modded? stock STi's n' all have stock moddifications, so they shouldn't really be 'stock' =\
torque demon is generally correct. eg, BMW 3.0l 6 = 300Nm and its 5.0l V10 = 520Nm...

Thanx ACS3....

blackie,

What my sig. says is that generally any motor with the same specifications (Heads, Cam/cams, ECU etc..) will make more torque if you increase the displacement. Therefore the only variable in the equation is displacement.

To further leverage the point. you bring me any motor in the world, with any mods, ill bring you a similar motor that make more torque with the only difference being displacement.

Put shortly displacement is directly proportional to motor's potential torque or how much torque that can ever come out of a motor, and subsequently power since power is toqrue x RPM.

An other way to look at it is that the limit to any motor's potential is displacement, but keep in mind that a piston engine is not very efficient and losses alot of power or energy due to in-effecincies like heat, friction and low volumetric effeciency (air that requires energy to be sucked into the engine by a piston which is designed to compress fuel mixture/transfer power).

Now if instead of letting the piston due the sucking/drawing-in the air you use the same amount of energy to drive a compressor like a supercharger (which is desinged to draw air in at pressure) you will achieve much higher volumetric effeciency and hence more power.

Now an other area where an engine lack volumetric effeciency is pistons having to expell the air out of the exhaust port. Again pistons are not effecient at doing this. If you use the energy wasted by pushing the air out to drive a turbine to draw/compress more air into an engine you will increase the volumetric effecieny in three ways. the first is by alowing the engine to swallow air instead of having to drawit in. The second is by putting the energy that is pushing the air out to good use. The third is because you are also compressing the air, you actually increasr the displacement or amount of air and subsequently oxygen and nitrogen into an engine.

There are many ways to "tune" or "modify" an engine, but they all try to make the engine either more effecient or larger (compressing more air into a smaller area = the main use of turbos and blowers/superchargers)

There is an other similar device that utilizes the exhaust air to directly drive the gearbox but I have yet to see it on cars. It is deadly in combination with Superchargers since it works on friction and the supercharger on volumetric effeciency. Add to that a ceramic block and heads and you have heat in your pocket too. that engine will make 3 times as much power than the same engine made from Iron without the supercharger and the turbo-geardriver device. I know about this as I studied it in college. Im an aeronautical engineer by qualification.

Hope that clears up things. :thumpup:
