Feet RSR Calculations.
Some dynamic compression ratio calculators like KBs ask for an additional 15 degrees of duration be added to the IVC 0050 lift point nnbfigure. It may be burning oil it may be leaking the compression may be so low that it only starts on cold days or maybe it just isnt very efficient anymore. Despite the fact that you cannot enter a ratio of 45 into this calculator it accepts values such as 45 for example 43 should be written as 43.
ENTER YOUR DATA CALCULATED DATA. Total Displacement ccs. Cylinder Head Volume cc Cylinder Head Vol cubic in Piston Head Volume cc.
The lower part contains p percent of the data and the upper part consists of the remaining data. Use this compression calculator tool to figure the compression you will get with the specifications you provide. This leads us to believe that it is fairly close at 821 dynamic to the maximum amount of compression we can run in this engine with 91 octane fuel.
Get your engines optimal compression ratio and total displacement in no time flat. The compression ratio can be easily found with the following formula. G is the shear modulus in GPa.
These three parameters are related according to the following equation. Rod Length in Adjusted Stroke in Intake Closing Point degrees ABDC 0050 lift plus 15 degrees. Dynamic compression calculator by Kelly Dynamic compression calculator by KB Wallace Racing DCR calculator.
Ie 100-p the total data equates to 100. For pistons ABOVE the block TDC - value in box must be a NEGATIVE number -000 Note. The following example goes over the steps required to convert a compression ratio into pounds per square inch PSI.
You can also use our Poissons ratio calculator to find Poissons ratio based on the values of shear modulus and modulus of elasticity. Compression Ratio to PSI Example. Engine Performance - Bore Size BoreStroke Ratio - Carburetor Size Needed - Engine Size - Engines Compression Ratio - Fuel Injector Flow from change in Fuel Pressure - HorsePower from Intake Airflow.
