This VHM insert calculator allows you to calculate the actual volume and squish on your engine. This can deviate from what's on the label of the insert box when the piston height of your engine is different from what's stated on the same label.
The calculator will do the mathematics for you!
First fill in the VHM insert specifications, which you can find on the label of the insert box.
Secondly, fill in the piston height you've measured on your engine and fill in the cylinder bore size. When all fields are filled, you can click on calculate to let the calculator show you the actual volume (combustion chamber volume including volume spark plug hole) and actual squish.
Use the point ( . ) instead of comma ( , ) as decimal seperator
