Compression Ratio

Compression Ratio

When building an Aircooled motor, one of the most important things is to determine what compression ratio CR you want to build the engine to.

I use a pipette with paraffin
A round disc cut different sizes for

  • 1600
  • 1835
  • 2L

2.4LBore with a hole in the center to fill the head with liquid. Use grease on the edge of the disc to seal and there you go

There after you go to pen and paper

I'll take some pics of actual formulas next

Hope this gives you guys a better idea
