Top Fuel Dragster Engine Facts

1. Top Fuel dragster engines burn up to 15 gallons of fuel in one run.

(NHRA)

If you ever thought your vehicle got terrible fuel mileage, it may bring a small amount of comfort to know that these incredibly powerful engines will burn up to 15 gallons in a single run. The catch: one run will generally be less than five seconds once the car takes off from the start line. Not only is that terrible fuel mileage, but this engine burns nitromethane, which is around $16 per gallon!

2. Horsepower numbers are estimated on most Top Fuel dragster engines.

(Hotcars)

The best Top Fuel dragster engines are estimated to be upwards of 10,000 or more horsepower. To put this into perspective, most of the fastest supercars in the world barely break 1,000 horsepower. Top fuel dragster engines are designed for absolute maximum acceleration. Because of the engine’s extreme horsepower, dynos don’t last long enough to get a precise horsepower reading. Therefore, the horsepower ratings are estimated based on the engine’s specs and how it should perform.


3. Top Fuel dragster engines have to be rebuilt after every run.

(Hotcars)

Perhaps one of the most shocking Top Fuel dragster engine facts is that the engines are rebuilt after every run. In stock car racing, it’s common for cars to need many things replaced in the pit stop throughout the lengthy race. But a Top Fuel dragster is getting this rebuilt after every quarter-mile run. Generally speaking, it is new pistons, rings, rods, and bearings. However, sometimes the engine needs a whole new crank as well. The craziest thing? The crew often only has a couple of hours to do the work.


4. Nitromethane powers Top Fuel dragsters instead of regular gasoline.

(Hotcars)

As mentioned earlier, Top Fuel dragsters run nitromethane instead of regular gasoline. Essentially, nitromethane is different from gasoline in that it carries its own oxygen, so it doesn’t require the same type of intake. Each stroke of your engine generates more power because it’s burning more fuel without needing extra space for as much oxygen.

Have you ever wondered why flames sometimes shoot out of the tailpipes of Top Fuel dragsters? It’s because nitromethane burns slower than gasoline. So what you’re seeing is actually ignited but unburnt fuel being pushed out of the exhaust.

5. A Top Fuel dragster’s primary braking method is parachutes

(Autoweek)

Can you imagine driving a vehicle so fast that you needed parachutes to stop? This is the case with most Top Fuel dragsters. They do have traditional brakes. However, their primary means of stopping at the end of their run is the deployment of one or two parachutes out the back of the car. It’s all about timing because the driver has a lever inside his cockpit that he must pull at just the right time. Too early and the parachutes impede his time, too late, and he risks not having them stop him in time.


6. The current quarter-mile record for a Top Fuel dragster is 3.623 seconds.

(Hotcars)

Tony Schumacher holds this record. Before deploying his braking system, he had the car traveling 336.57 miles per hour. This was a record, but the rest of the racers likely all passed the 300 miles per hour mark during that race. This is a testament to the insane amounts of power these car engines put out.


7. At Launch, drivers of a Top Fuel dragster can be subjected to nearly 5 Gs of gravity.

(Motortrend)

We are generally subjected to no more than 1 G of gravity in our day-to-day lives. Top Fuel dragsters engines put out so much power that the drivers are often subjected to nearly 5 Gs of gravity. This means that the driver feels five times his body weight being sucked into the seat. It takes training to be able to withstand this force without feeling sick.

Owning a Top Fuel dragster

8. Top Fuel dragsters can cost over $500,000.

(HowMuch)

This price only takes into account purchasing a relatively new or high-tech dragster. It doesn’t necessarily account for aggressive, ongoing costs such as nitromethane fuel and engine rebuilds after every run.

A Top Fuel engine will generally be approximately $60,000 with a rebuild cost of around $5,000 every time. When you account for how many times the engine will likely have to be rebuilt in a year, that puts the average cost in excess of $1 million dollars per year for rebuilds alone.

Another significant cost is the particular fuel. Nitromethane is typically around $16 per gallon, and at approximately 15 gallons per run, that puts one run at around $240. This may not seem like a huge number, but if you account for doing over 150 runs per year, it adds up in a hurry.


9. No special license is required to purchase a Top Fuel dragster.

(HowMuch)

Even though no special license is required, it’s not quite that simple. If you have the money to purchase and maintain a Top Fuel dragster, then you can technically buy one. However, the only people you will ever see driving one of these powerful machines will be trained professionals. You don’t just jump from a Honda Civic into a dragster! Some dragsters are owned by wealthy enthusiasts who employ professional drivers to race for them.

Top Fuel Dragster Engine Facts: FAQ

Why Do the Drivers Spin the Dragster’s Tires Before Its Run?

If you’ve ever watched a drag race, you’ll notice that most drivers will spin the tires of their car in place before they start their run. This is primarily for grip. As the tires spin, they heat up, and the rubber softens and grips the surface of the road just a bit better.

How About Those Spark Plugs?

Because a Top Fuel dragster engine runs so hot, the electrodes on the spark plugs are completely destroyed at only halfway through a run; the engine runs on its existing combustion and exhaust valves from that point on. Because of this, only stopping the flow of fuel through the engine will turn it off. You can’t just turn a key to shut the engine down.

How Loud is a Top Fuel Dragster Engine?

All this talk about how powerful these incredible engines are; you might be wondering how loud they are. Not only do many Top Fuel dragsters measure a 2.3 on the Richter scale on launch, but they have also measured 144db’s and even into the 150s. So, needless to say, you’ll need some pretty good hearing protection if you want to watch one of these races live. (ESPN)

Conclusion

You won’t see Top Fuel dragsters taking hairpin corners, but they are exhilarating in their own way. To sit in the crowd and literally feel the 10,000 plus horsepower scream by in your chest is an experience that you won’t soon forget. If that kind of event isn’t your thing, even watching it once on TV is something to behold.
