- Does anyone know what the acceleration curve for a typical Top Fuel dragster
- is?
- >
- I saw the NHRA Northwest nationals in Seattle, and did some timing.
- >
- They did the first 60 ft in .9 sec, meaning 4.6g's average, so peak
- acceleration is something higher than this.
- >
- They did 1/4 mile in 4.9 sec, meaning an avg of 3.41 g.
- >
- They got up to 295 mph in 4.9 sec, acceleration of 2.74g average.
- >
- Therefore, their actual acceleration is high at low speed, somewhere above
- these average values, and something lower than average at the finish line.
- (Kind of neat how they can do better than 1g with no aerodynamic downforce at
- the line)
- (I hear they get 800lb downforce from exhaust pressure, 1900lb car.)

- Does anyone have a complete curve?
