To enter head gasket displacement volume, in the "Gasket Thickness" field enter ".0001". If you have the actual displacement in ccs of the exact head gasket you are using, you can get an even more accurate compression calculation by using those figures. This tool is a very accurate tool and can be tremendously helpful. You can change the head ccs, deck height, overbore size, etc. Use this compression calculator tool to figure the compression you will get with the specifications you provide. Ratio Calculator and Engine Size Calculator We strongly endorse this product if you are serious about improving your vehicles performance and your success at the track. Universal for or use to do any mathematical calculations related to engine performance and vehicle E.T. Easy to use, self contained, no additional computer or monitors required (accurate weather data required for some ET calculations) Hand held, take it anywhere, and includes protective Armadillo case at no additional charge. Quick reference guide with 100s of formulas included for ease of use. Pre-programmed formulas for engine building and track tuning. This is the chance to know up front how changes will translate into power and performance, so before you spend your time or money, use the Hot Rod Calc to get the answers. Hot Rod Calculator - Street and Strip performance calculator for use by racers, engine builders and automotive enthusiasts. At the track, see how things like gear ratio changes or weather conditions can effect your E.T.

We are pleased to share these helpful tools with our valued customers and guests. High Performance starts with math, precise measurements and calculations. Divide those numbers and you have the compression ratio for your application.Free Horsepower Calculator Compression Ratio Calculator Race Math Formulas and Racing Math Resources The result is the value at T.D.C (denominator). Then take the same number and subtract volume 1 from it. This is the total volume at B.D.C (numerator). With all 5 values known, add them together. If you do need to make this measurement, it’s the same way you would measure a combustion chamber. Since our application is completely flat, there’s no need for this measurement. If it had a dome, it would take away volume and if it had valve reliefs it would add value. The final measurement is piston top volume. 7854 x Gasket Bore² x Piston Depth x 16.39 = 1.10 cc

and assumes measurement of a perfectly flat piston with no dome or dish: The fourth measurement is cylinder volume at T.D.C. The manufacturer will provide the bore and compressed thickness of the gasket and will use those numbers much like we did for measuring the cylinder volume: The third measurement is head gasket volume. Most manufacturers will list this on their spec sheet but if there’s any doubt you can measure it yourself. The second measurement is combustion chamber volume. We do this because the equipment is designed to measure in metric volumes. This equation converts the results from cubic inches to cubic centiliters. The bore is 125 and the stroke is 4″ so you can just plug those numbers into the equation for the volume of the cylinder:

To stay organized it’s helpful to list them on a sheet. To determine compression ratio there are 5 volume measurements.
