Progressive Nitrous Flow Calibration

See how much nitrous actually flows at each controller setting you tested.

50% on your controller may not deliver 50% of the nitrous. Enter your measured test results below to see how your setup responds.

What do I enter?
  1. Controller setting: the percentage used for that test.
  2. Nitrous used: bottle weight before the test minus bottle weight after it.
  3. Test length: how many seconds the nitrous flowed.

Include a test at 100% controller setting. This is your full-flow reference. Use measurements from the same setup and comparable bottle pressure. Exclude purging or other bottle losses from the measured amount.

1. Enter your test results

Use one card for each controller setting you tested. Leave unused cards blank.

Optional test notes

Saved on your printout as test notes. These do not change the calculation.

2. Your measured nitrous flow

Method and assumptions

Each rate = measured mass loss ÷ test duration. Full-flow fraction = measured rate ÷ rate at 100% duty × 100. The chart and table show your measured tests. Lines connect the points as a visual guide. If no 0% test is entered, a zero-flow starting point is added to the chart only; the table retains your actual measurements.
