Why race cars used diffrent kind of fuel..?? can stock production cars use racing fuel too..???

Answer 1

You could but it will not make power like a race engine and it may even damage the engine. Race engines are built internally in a manner that require them to use higher octane fuels such as alchol and so fourth. Your stock engine was designed to burn pump gas and you would most likely burn pistons, valves, ruin injectors and screw up the entire smog system of you go and dump race fuel in your stock car. The reason race engines use race fuel, is because they need it. A stock engine has been designed to operate on the 85 octane that you buy at 7-11.

Answer 2

many diff rent reasons, champ car used methanol because it deludes with water, some fuels are decided because they burn hotter and give you more bang for your buck, also they are cleaner and the less carbon deposits in an engine the less chance of blowing one

as for can it run in your car ?depends on the type of fuel, some 100 octane racing gasoline yes you can in fact it will even clean your motor, but you'll pay an arm and a leg, now if your talking about methanol or any other non "gasoline" fuel id avoid it until i talked to someone that works in the industry, the different temps might not do you so good,
but as for the other guys saying how they rebuild engines after every race a lot of that has to do with constant hi rpms 8500rpm in nascar 12,500rpm irl/champ cat and 19,000rpm F1 with much thinner engine lubricants than production cars use

Answer 3

nope, unless you do some MAJOR modifications!
Methanol burns at a higher temperature, and race cars REPLACE the engine after every track race!
A bit expensive!

Answer 4

you sure can if you want to blow up your car racing fuel has very high octaine and runs to hot for street cars
