How do you calculate ET from horsepower?
To estimate the peak horsepower, maximum work output should be applied from start to finish….The Elapsed Time (ET) Method.
| Horsepower = | Weight |
|---|---|
| (ET/5.825)3 |
How do you calculate power-to-weight ratio?
It’s very easy to calculate a power-to-weight ratio. Simply divide the power output of a vehicle by its weight. For example, if you have a car that weights 2000 pounds and has 250 hp, the PWR will be as follows: 250 / 2000 = 0.125 hp for every pound of car.
What is the formula for calculating the speed of a trap?
TRAP SPEED (mph): The formula for ET involves the cube root of the weight-to-power ratio multiplied by a constant of 5.825, while the formula for Terminal MPH calls for the cube root of the power-to-weight ratio multiplied by a constant of 234.
How fast is 8.5 second quarter mile?

What is quarter mile trap speed?
Calculate ¼-mile ET and trap speed For example, a 2,400 pound vehicle with 300 horsepower should make it through the quarter-mile in 11.65 seconds, with a trap speed of 117.08 miles-per-hour.
How do you calculate speed from horsepower?
Relating Horsepower to Speed You know the horsepower rating of the engine, and now you know the thrust, so you can calculate the speed the car will travel using the relationship: Speed = Power/Force.
How much horsepower is too much for a daily driver?
That doesn’t mean you can’t drive it on the street and drive it to work…but the modifications needed to create and then reign in (trans/gears/diff/bushings/motor mounts/etc) 1000hp are adverse to a good daily driver…
Is an 11 second quarter-mile fast?
A fast quarter-mile run time for a production car is roughly under 11 seconds.
What is considered a fast 1/4-mile time?
How fast is a Tesla plaid in a quarter-mile?
We tested a 2021 Tesla Model S Plaid, and it reached 60 mph in 2.1 seconds on the way to a quarter-mile pass in 9.4 seconds at 151 mph. That 60-mph time ties the Porsche 918 Spyder and 911 Turbo S, and it matches the Bugatti Chiron Sport’s quarter-mile time, which is the quickest we’ve ever measured.
Is higher power-to-weight ratio better?
Power to weight ratio is the ratio between the power that your vehicle has and its weight. The higher the number, the better. For example if your car has 300HP and weights 1000 pounds, the power to weight ratio is 0.3 HP/pound, which means that your car outputs 0.3 HP for every pound it weighs.
