Running and Testing an Engine
The manual test would let us start an engine and decide how long, and at what RPM we want to run the engine. We can use this to test things like fuel economy, reliability, endurance, etc. It would be cool to see the engine heat up and see the pipes begin to glow red while running at high RPM for a long time. It would also be fun to test the car at lower RPM (between 1000-1500) to test things like fuel economy and how smooth the engine runs, or how it idles, etc.
