Compression Ratio Calculator is probably the most detailed compression ratio calculator program available.
Main features:
-Calculating compression ratio, cylinder volume, and engine displacement from a variety of different inputs.
-Finding which input value (chamber CCs, Deck Ht Clearance, etc) will produce a desired C.R.
-Determining the % contribution of various dimensions on the overall compression ratio.
-Calculating Bore/Stroke and Rod/Stroke Ratios.
-Calculating boring and/or stroking effects.
-Determining required bore or stroke for a desired displacement.
-Calculating cranking compression pressure and dynamic compression ratio.
-Saving and printing specs.
-Using English or Metric units.
-Determining piston dome or dish volume.
-Enter Head Gasket volume as Bore and Thickness, or Volume CCs directly.
-Determining any of the following: rod length, deck height, deck height clearance, piston compression height, or stroke based on you specifying the other 4."; function tShowHide(id, show) { var s = document.getElementById("desc"); if ((s.innerHTML.length<=212 || show==1) && show!=2) { s.innerHTML = fDesc[id]; if (document.getElementById('m1')) document.getElementById('m1').style.display='none'; if (document.getElementById('m2')) document.getElementById('m2').style.display='none'; if (document.getElementById('more_txt')) document.getElementById('more_txt').style.display='inline'; } else { s.innerHTML = ''; } }
