How Much Horsepower Does It Take To Turn A Top Fuel Supercharger?

At maximum pressure, it takes approximately 1,000 horsepower (745.7 kW) to drive the supercharger.

How much horsepower does it take to spin a Top Fuel supercharger?

That’s because the nitro works to pull the heat out of the air despite the immense power required to drive the blower. Miller estimates it takes between 900 and 1,000 crankshaft horsepower to drive one of his superchargers. Just let that last fact settle in for a moment.

How much horsepower does it take to run the supercharger on a Top Fuel dragster?

However, superchargers take power to make power; the blowers on Top Fuel dragsters generally need over 700 horsepower to provide the right amount of air for the car to produce the magic 11,000 hp.

How big is the supercharger on a Top Fuel dragster?

To suck in as much air as possible, Top Fuel dragsters run a huge positive displacement Roots type supercharger: at its highest, this supercharger alone absorbs around one thousand horsepower, but can reach pressures around 60 to 65 PSI (up to 4.5 bar, limited by the rules).

How much horsepower does a Top Fuel dragster need?

11,000 horsepower
A Top Fuel Dragster—distinguished by a supercharged, custom-built, 500-cubic-inch engine—boasts 11,000 horsepower and burns nitromethane. By contrast, a Top Alcohol Dragster’s output is about approximately 4,000 hp.

Can you put a supercharger on a stock engine?

Because superchargers push the air/fuel mix into an engine, they’re well suited to stock motors — provided you don’t get greedy with how much boost you want to run or how hard you want to rev the engine.

What RPM does a supercharger spin at?

The supercharger begins increasing intake air pressure just above idle. Between 2,500 and 3,500 r.p.m. both blowers work cooperatively to boost the intake air to a regulated 22 pounds per square inch above atmospheric pressure.

Is anything faster than a Top Fuel dragster?

Top Fuel dragsters are the quickest accelerating racing cars in the world and the fastest sanctioned category of drag racing, with the fastest competitors reaching speeds of 335 miles per hour (539 km/h) and finishing the 1,000 foot (305 m) runs in 3.64 seconds.

How much HP does nitromethane add?

It has been learned that nitromethane can increase power output by as much as 13 percent on an indicated or gross basis when added to methyl alcohol and by 7 percent when added to a benzene-isooctane mixture in concentrations of 20% by volume.

What is the fastest a Top Fuel dragster has gone?

Brittany Force sets national record with fastest Top Fuel run in history: 338.48 mph. Brittany Force made the fastest run in Top Fuel history and reset the national speed record to 338.48 mph in her Flav-R-Pac dragster in the opening round of the NHRA Midwest Nationals at World Wide Technology Raceway.

How much money does a Top Fuel dragster make?

The base salary for Top Fuel Drivers in companies like NHRA range from $41,116 to $55,609 with the average base salary of $48,060. The total cash compensation, which includes bonus, and annual incentives, can vary anywhere from $41,380 to $56,129 with the average total cash compensation of $48,378.

How many g’s do you feel in a Top Fuel dragster?

5 G’s
The modern NHRA Top Fuel dragster accelerates harder and pulls more G’s than any [unclassified] fighter jet launch. At 5 G’s, there’s no wheeled vehicle on earth that even comes close.

How much fuel does a Top Fuel dragster use in a quarter-mile?

NHRA Top Fuel dragsters and Funny Cars consume between four and five gallons of fuel during a quarter-mile run, which is equivalent to between 16 and 20 gallons per mile!

What’s the fastest 1/4 mile time ever?

8.58 seconds
1/10 2021 Rimac Nevera
The one and only Rimac Nevera is currently the fastest 1/4-mile car in the world with a time of 8.58 seconds.

How much is a gallon of nitromethane?

NHRA teams pay $1800 for a 40-gallon drum of nitromethane, so they’re paying $45 a gallon—and that’s a group discount negotiated for the entire racing season. Every single run consumes 14 gallons of fuel to run wide-open throttle for 1000 feet, costing about $600 (10% of the fuel is alcohol, which is less expensive).

Does NHRA Top Fuel run 1 4 mile?

Traditionally, a drag strip is 1,320 feet, which equals a quarter-mile. (One mile equals 5,280 feet.) Many classes in NHRA drag racing—actually, all but the Top Fuel and Funny Car classes—still compete on a quarter-mile course.

Will a supercharger shorten the life of my engine?

A supercharger puts a huge amount of stress on an engine through kinetic energy and heat production, therefore many engine components have to be over-engineered to cope with the additional strains put upon them. In most cases, this then leads to added weight and diminishing returns in terms of performance.

What gives more hp turbo or supercharger?

Supercharging Pros: Produces significantly more horsepower than turbocharging. A quick solution to boosting power in larger displacement engines with more cylinders. No power lag as is seen with turbocharging; power delivery is instantaneous.

Is it better to turbo or supercharge a v8?

While the turbo’s primary drawback is boost lag, the supercharger’s is efficiency. Because a supercharger uses the engine’s own power to spin itself, it siphons power—more and more of it as engine revs climb. Supercharged engines tend to be less fuel efficient for this reason.

What runs hotter a turbo or a supercharger?

Turbos run much hotter then superchargers and because of this turbo bearings can get nuked because of the heat. Also if a turbo is turned off to quickly after being under a large load, it is possible for a turbo to burn itself up (possible).

At what speed do turbos kick in?

between 80,000 and 200,000 rotations per minute
In order to achieve this boost, the turbocharger uses the exhaust flow from the engine to spin a turbine, which in turn spins an air pump. The turbine in the turbocharger usually spins at speeds between 80,000 and 200,000 rotations per minute (rpm) — that’s up to 30 times faster than most car engines can go.
