Engine Performance
| Engine | Speed | Effective Stress Capacity |
|---|---|---|
| Standard Portable Engine | 32 RPM | 2,048 SU |
| Iron Portable Engine | 64 RPM | 8,192 SU |
| Gold Portable Engine | 96 RPM | 18,432 SU |
| Diamond Portable Engine | 128 RPM | 32,768 SU |
| Netherite Portable Engine | 256 RPM | 163,840 SU |
The Netherite Portable Engine is capped at 256 RPM to prevent Create's overspeed protection from destroying connected components.
When superheated with a Blaze Cake, the Netherite engine remains at 256 RPM and receives twice its normal stress capacity.
Crafting Recipes
Each Portable Engine is upgraded using the engine from the previous tier.

All four recipes use the same basic layout:
- A Create Steam Engine in the top-center slot
- Two Fluid Tanks in the middle-left and middle-right slots
- A Shaft in the center slot
- Four matching material blocks in the corners
- The previous-tier Portable Engine in the bottom-center slot
Upgrade Progression
- Iron Portable Engine: Standard Portable Engine + Iron Blocks
- Gold Portable Engine: Iron Portable Engine + Gold Blocks
- Diamond Portable Engine: Gold Portable Engine + Diamond Blocks

Recipes can also be viewed using JEI or another compatible recipe viewer.
