I'm not sure what "race legal" means but race cars typically use higher octane fuel such as 102 and up. Street legal cars use fuel commonly available at the pumps. Depending on the state you're in you'll find anything from 87 (low octane) to 92 and up (high octane). The difference between the octanes rating is the tendency for pre-detonation. High horsepower race engines have high compression ratios and need a fuel that wont ignite before the compression cycle is done.
Yes, some gas stations even sell race fuel that's called, "Turbo Blue." You can use it whenever you want it doesn't have to be just to clean the car out, in fact I recommend stable oil to clean the car out, you simple poor one ounce of it for every gallon of gas. You can get that at any gas station or stores like, "Car Quest," and, "Advanced Auto Parts."
The petrol will combustion will be bigger, thus there is more horsepower and the car will go faster.
Street cars air (which is manily Oxygen, nitrogen), race cars nitrogen.
The racing car is an unlockable of level 7. to use it, you have to complete the requirements for all 3 street race in that level You must win each race , then go to a phone booth to use it. Thanks
The cubic inches of the engine in a NASCAR race car must be the same as the cubic inches of the street car engine they represent. (you can't get a V8 engine in a Camry so the previous line is false.) Other than that there is virtually nothing similar between a NASCAR engine and a street car engine. Most street cars today use advances in fuel efficiency such as fuel injection, electronic ignition and a host of sensors and vacuum control to help keep pollutants low. NASCAR race cars still use the tried and true technologies of a bygone era such as carburetors and distributors. Also, most of the engine options for the street cars these race cars are modeled after use overhead camshaft (OHC) and a front wheel drive configuration, whereas the race car engines use overhead valves (OHV) and a rear wheel drive configuration. However is is important to point out many sports cars and larger vehicles (trucks, vans, SUV's) still use OHV engines and real wheel drive. NASCAR engines even run on leaded fuel still. A NASCAR engine can cost over 1 million dollars to build.
Yes. There are several racing series that use older NASCAR race cars, so they are available for sale. They are very expensive. If what you really mean is "can I buy a NASCAR and drive it on the street," the answer is no. It would cost more to make a stock car street-legal than it would to buy a brand-new street car that your favorite driver's car is patterned after and have it decorated like a stock car at a body shop. People do that.
It is a race car, some of the cars have been converted to legal street cars ( minor changes to make it legal to use outside the track )
go to blueprints and change it to whatever race type you want
We use it in a car
if we do not use fuel properly our car will destroy
Yes, you can use unleaded fuel even if your car calls for super unleaded fuel. These are essentially the same kind of fuel so it will not mess up the performance of your car.
Race car tires are super sticky. And when I say sticky I mean like GOO. A pebble pushed onto the smooth tread will STICK there. These tires are not legal for street use.
