1. What is ET for 1320 ft?

ET (Elapsed Time) for 1320 ft refers to the time it takes a vehicle to complete a quarter-mile distance, which is the standard drag racing measurement. A quarter mile equals exactly 1320 feet.

2. How Does the Calculator Work?

The calculator converts elapsed time to speed measurements:

Where:

• ET — Elapsed Time in seconds
• 1320 — Feet in a quarter mile
• 5280 — Feet in a mile
• 3600 — Seconds in an hour

3. Importance of Quarter Mile Timing

Details: Quarter-mile time is the standard performance measurement in drag racing. It provides a consistent benchmark for comparing vehicle acceleration and performance across different makes and models.

4. Using the Calculator

Tips: Enter the elapsed time in seconds that a vehicle took to complete a quarter-mile distance. The calculator will provide the average speed in both feet per second and miles per hour.

5. Frequently Asked Questions (FAQ)

Q1: What is a good quarter-mile time?
A: For production cars, times range from 14-16 seconds (sports cars) to 8-10 seconds (professional drag racing vehicles).

Q2: Why is quarter-mile distance used in racing?
A: It provides a standardized distance that's long enough to test acceleration capabilities but short enough to be practical for racing events.

Q3: How accurate are quarter-mile timings?
A: Professional drag strips use precision timing systems accurate to 0.001 seconds, while amateur measurements may have slightly less precision.

Q4: Does weather affect quarter-mile times?
A: Yes, temperature, humidity, and air density can significantly impact vehicle performance and elapsed times.

Q5: What's the relationship between ET and trap speed?
A: ET measures how quickly you cover the distance, while trap speed (measured at the finish line) indicates the vehicle's maximum speed achieved during the run.
