How fast does a 4-wheeler have to go to ... ???

Pretty fast...i would say around 40...
367655
without being modified I would say the Ducati it goes way past 200 mph, very quickly

the fastest I know of would be the Bugatti Veyron 16.4.  they are handbuilt with a 1001 Euro (987 SAE) horsepower, 8.0 liter quad-turbo DOHC 64-valve W-16 engine with 7-speed auto-clutch manual transmission, and tops out at 250+ mph.  in the 7th gear, the car gets less than 3 mpg.  a second key is required to program the engine into "top-speed" mode, where you can go 0-250 in less than 60 seconds.  an air-brake is required to take the car down from 250+ to 160 mph, and the audio system alone costs US$30,000.  a deposit of 350,000 is required to place an order, for a final cost of about $1.25 million.  it will be available in the US about summer 2006, and was recently featured in the January 2006 issue of Motor Trend magazine.

20in haulers, and if someone says something different, they are on crack.\n\nI have talked to lots of people and the sand dunes, have read up on it, and have tested several different kinds and tires. The one that gets the hp to the ground in sand is the haulers. \n\nBy the way, I have the same quad as you. We go to Silver Lake in Michigan a couple times a year. I have never seen any serious person drag race, that didn't have haulers. I have found the cheapest place to get sand tires is forums. Get on a forum and tell them you want to buy some used tires, it will save you a hundred bucks.\n\nAlso, if you didn't know, that is a common bolt pattern, that is used on lots of quads.

Speed of.. gravity? :S

yes, check out the bugatti veyron (world's fastest car- does 0-60 in 2.5 seconds) and the dodge tomahawk (bike that has a dodge viper engine). I don't know if they can go that fast, but pretty close for land vehicles.

If you are talking sport bikes, it would probably still be the suzuki hayabusa 1300R. Unfortunately most of the nuts that own these monsters don't feel that they are fast enough, so they turbo charge them... The results... 8 second 1/4 mile times at over 160 MPH. Its pretty sick to watch.

Acceleration is based on weight transferance and the 4 cylinder will be lighter, but once going the v12 will beat the 4 cyl due to the fact that you have more cylinders doing more work. 4 cyl must create power in only 4 areas 12 cylinders has more over all power due to more cylinders

Not going to be to great, around 200-225 HP. But it will have good torque.

A Lot of factors to consider here.\nSize of the Windmill?\nWeight of the car?\nWeght of the cargo?\nWind speed?\nFor discussion's sake, let's figure the the windmill is 6' high.\nMounted to the top of the vehicle going 'with the wind'. and you're using a generator capable of producing 5 hp..\nA 15 mph wind should do it...\nThat's, of course, taking advantage of the push from the wind as well.

A standard 22-250 is pretty fast as is.  I would just go with the fastest factory load you can find.

70 MPH, 90 BHP.  Cause everyone knows that all honda engines have no torque.
310980
about 1000 mph.\nSome say 1040 mph.

It's a question of horsepower.  And durability.  You could sufficiently gear your car to theoretically go 60 mph at 1000 rpm, but you have to remember the amount of work being done is real - you would not be able to push the car through the air at that engine speed, never mind have sufficient power in reserve to climb a hill or accelerate.\n\nIn an ideal world, your engine would have an infinite numer of gear ratios, or be infinitely variable to some perfect power/speed ratio.\n\nThen, you would travel in a different gear depending on how much you had eaten for lunch.

Easy try doing bicycle first then practice 2 wheeler every day I'm 13 but i drive two wheelers that can go 140km/h so you will if you do it and get used to it DUDE! GLAD TO HELP IF WORKED!
