  • Humidity: 30%
  • Surface: Asphalt
  • Tire Pressure: Recommended levels

Testing Procedure

The testing procedure involved the following steps:

  • Start from a complete stop.
  • Accelerate to 100 mph as quickly as possible.
  • Use a GPS-based timing system for accuracy.
  • Record the time taken for each run.

Results of Performance Testing

The results from our performance testing revealed significant differences in acceleration times between the stock and modified S13 240SX.

Stock S13 240SX Results

  • Run 1: 0-100 mph in 8.2 seconds
  • Run 2: 0-100 mph in 8.0 seconds
  • Run 3: 0-100 mph in 8.1 seconds

Modified S13 240SX Results

  • Run 1: 0-100 mph in 5.6 seconds
  • Run 2: 0-100 mph in 5.5 seconds
  • Run 3: 0-100 mph in 5.7 seconds

Analysis of Results
