Workshop Purpose

This resource turns a broad topic into a repeatable workshop reference. It is designed for students and mechanics who need a clear diagnostic or study path before downloading forms or using the live calculators.

How To Use It

Start with the focus points below, gather measurements, then move into the related checklist or calculator. The goal is to document the failed test instead of guessing the failed part.

Focus Points

  • Engine geometry
  • Compression testing
  • Fuel and air demand
  • Dyno interpretation

Related Next Step

Use the protected checklist library for printable worksheets, or return to the live calculator hub when the next decision needs a number: voltage drop, compression, sag, gearing, brake torque, charging time or fuel range.
