On the other side of the axis, force is being exerted from the axis in the opposite direction 5 meters from the axis. Compression Calculator Simply fill in the form below to calculate your compression ratio > Bore: (diameter) in. The magnitude of the torque on one side of the axis is 200 N∙m. CALCULATOR Crankshaft stroke length Connecting Rod Length Head gasket compressed thickness Deck Height Piston to Deck Combustion chamber volume Bore. For example, suppose you're told that the net torque is zero.If you're given the net torque but not some other variable, such as the force, use basic algebraic principles to solve for the missing variable. The compression ratio is a single number that can be used to predict the performance of any internal-combustion engine. If the net torque is zero, you have a balanced system. If one force is pushing or pulling in the opposite direction of the other force, the object will rotate in the direction of the stronger torque. It's possible to have more than one force acting on an object at a different distance from the axis. Stock bore, stroke, HG thickness, pistons roughly 0.006" above the deck (hence why its a negative #), flat-tops with roughly 0.5cc due to the intake valve notch, and an estimate combustion chamber volume for PI heads shaved 0.Total individual torques around a given axis to find the net torque (Στ). So do not use a negative sign in the "deck height" nor "piston top volume" entry field unless you truly are using pistons above-deck or they have an upward-dome. Compression Ratio Calculator 'Other' input for any volume not in calculator.

The negative sign in these instances just refers to the fact that it is a downward dish. Welcome to the Future of Dyno Simulation Software Virtual Engine Dyno is a computer software program used by engine shops and performance enthusiasts to simulate Building, Modifying, Tuning and Dyno Testing automotive engines before component purchases and engine assembly. To determine the deck height required for a 2007cc engine with a compression ratio of 8.5:1, and cylinder heads with a combustion chamber volume of 56cc. The new improved Helical Compression Spring Calculator allows you to print or email the calculations for later reference. (Note that BCT is not stacking strength, which is the maximum load a box can handle throughout the distribution cycle. To calculate the rate, enter the wire size, diameter and number of coils required to construct the spring. Box Compression Test (BCT) Strength Estimates the BCT of a regular slotted container (RSC) for a moment with flutes positioned vertically. I see a lot of online references to piston dish as "-10cc, -17cc", etc. Helical (round wire) Spring calculator, for designing and manufacturing compression springs. There are NO negative numbers anywhere, EXCEPT if your pistons are going to ABOVE the block's deck surface, or if your pistons are domed upwards. (considers cam timing and rod ratio) This calculator will give you the proper compression ratio with a known piston head volume. Data compression ratio, also known as compression power, is a measurement of the relative reduction in size of data representation produced by a data.

Most of these values I got from a list I had saved over the years, so if I made a mistake, feel free to correct me via PM.Ģ. Where PSI is the pounds per square inch X:Y is the compression ratio P is the pressure (typically standard atmospheric pressure (14. The following formula is used to convert a compression ratio to PSI. The values I listed above are nominal values that can be used for a "starting point". Compression Ratio Calculator Compressibility Calculator Pounds Per Square Inch Calculator Compression Ratio to PSI Formula.
Also, combustion chamber volumes for OEM/FRPP heads are usually listed as ± 1.5 cc's, so there is generally some variance. The bore on the HG is slightly larger, so when the number crunching is done, it calculates a smaller HG volume than there really is, so your actual CR will be just a smidge lower, but not by much.
Now, this online calculator assumes the HG bore diameter is the same as the engine bore diameter, when in reality it is not the same.
