Saving and printing specs. Using English or Metric units. Use a burette and flat plastic cc plate to measure the total volume. To calculate dome volume: first, position the piston a measured distance into the cylinder, making sure the dome is below the deck. Calculate your engine's piston dish volume or piston dome volume. All data is entered as a POSITIVE Value and the . 000) Note: For a DISH piston – value in box must be a NEGATIVE number (-0. 0 range but a small swing either way effects the readings quite a bit. By convention, the volume of a container is typically its capacity, and how much fluid it is able to hold, rather than the amount of space that the actual container displaces. MAHLE Motorsport – Influence of bearing grooves Rotate the crank until the piston is . Dome calculation tools Below are links to various dome tools for calculating strut lengths, floor area, panel sizes and other useful measurments for building geodesic, segmented and other types of dome. When they advertise a dome, they couldn't mean 0. 025 down in the cylinder, the block doesnt look like they decked it, so it'll be stock. Generally, the volume of a container is understood as its capacity — not the amount of space the container itself displaces. Enter Piston Dome Volume In CCs Negative For Dished Pistons (Use '-') If you buy a domed piston, there will be a specification for the dome volume.
