Basically, they don't. The power that's generated is so intense, and the duration is so short, that a coolant system wouldn't be able to keep up. The engines are simply built to take it for the few seconds each race lasts. Some cooling is provided by the large amounts of fuel that's being dumped into the cylinders, but that's about it.
Some use gasoline, some use alcohol, and the top fuel dragsters burn nitro methane.
$180,000-$200,000 $180,000-$200,000
Top fuel dragsters regularly hit 300mph by the quarter-mile mark.
top fuel dragsters
Top Fuel dragsters racing in the NHRA.
They are around $250,000.
Very basically they have internal combustion engines just like a family car. The fun of course is in the differences! The road car needs to go steadily and use as little fuel as possible. The top car's aim is to burn fuel as fast as possible to deliver that short but intense burst of speed. One of the main ways it does this is to burn a very different fuel, nitromethane mixed with a little methanol.
Yes, all Top Fuel Dragsters and Funny Cars are supercharged hemi's.
Top fuel dragsters can reach speeds of over 330 miles per hour (531 km/h) in just a few seconds during a race. These vehicles are powered by supercharged nitromethane engines, allowing them to accelerate from 0 to 100 mph in less than a second. The combination of advanced engineering and extreme power enables these dragsters to achieve such incredible speeds on the track.
1/4 mile top fuel dragsters can do the 1/4 mile under 5 seconds
Any car or motorcycle that is a true "TOP FUEL" vehicle, uses a mixture of methanol (alcohol) and nitromethane. The current NHRA rules allow for a mixture of 90% nitromethane to 10% alcohol.
Dragsters can be classified based on their engine type (e.g. top fuel, funny car), body style (e.g. rail, altered), and class designation (e.g. Super Comp, Top Alcohol). They can also be categorized by their level of competition, such as professional or sportsman drag racing.
