Engine compression calculator download

It covers a huge range of calculations that are important to gearheads, everything from engine compression ration calculations to rear end gear ratio and tire size affects on rpm and mph. We strongly endorse this product if you are serious about improving your vehicles performance and your success at the track.

We do not sell Mr. Gasket products but we wanted to share this great tool with our customers. The best deal we have found on it is here: Mr. Gasket Hot Rod Calculator They have a low price guarantee, free shipping and they always get our orders to us fast. Choosing the correct piston is one of the most important aspects of getting the best possible performance from your engine, in your exact application. We sell a wide variety of pistons from many different manufacturers, all with different specs.

You can use this compression ratio calculator to compare different piston combinations, as well as seeing what changes in cylinder head chamber volume, block deck height and head gaskets have on final static compression ratio. You can try different combinations by changing the head chamber volume ccs, engine block deck height, cylinder bore size, etc.

This static compression ratio calculator is an accurate tool and can assist you with selecting the best combination of parts for your engine. You can enter the displacement in ccs of the exact head gasket you are planning to use if you have that spec.

Using the gasket ccs is a bit more accurate than using the gasket thickness as when using the thickness an approximation is made about the gasket ccs by the formula. To use the actual head gasket displacement volume do the following. In the "Gasket Thickness" field enter ". How to use this calculator: Simply fill in all the boxes below with the requested figures and click on "Calculate CR" to find your engine's compression ratio.

The compression ratio of an engine is a very important element in engine performance. The compression ratio is the ratio between two elements: the gas volume in the cylinder with the piston at its highest point top dead center of the stroke, TDC , and the gas volume with the piston at its lowest point bottom dead center of the stroke, BDC.

There are two ways of calculating the compression ratio for an engine. Firstly, you can make a math calculation as accurately as possible, or secondly - the more popular method - uses an empty spark plug socket with a pressure gauge inserted. We're looking at the first of these ways here. This technique is suited to someone who is in the middle of putting an engine together and has the right tools, or someone whose engine is already in pieces.

Bore in. Stroke in. We strongly endorse this product if you are serious about improving your vehicles performance and your success at the track.

Use this compression calculator tool to figure the compression you will get with the specifications you provide.

You can change the head ccs, deck height, overbore size, etc. This tool is a very accurate tool and can be tremendously helpful.

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. To enter head gasket displacement volume, in the "Gasket Thickness" field enter ". Then combine the gasket displacement ccs with the "Head" ccs.

For instance, if you have a 64cc chamber and a head gasket displacement of 9. This tool can also be used to find the final engine size based on any bore size, crankshaft stroke and number of cylinders. You can use this for example to see how big your stroker engine will actually be as far as displacement, based on different bore sizes or crank strokes. This tool is very accurate for displacement calculations. When using the tool for engine size calculations only you can put most any reasonable numbers in the fields that are used to calculate compression ratio, but you must put something in all fields for the tool to work.

The 3 critical dimensions for displacement calculations are bore, stroke and number of cylinders. Then enter the total weight of your vehicle, as raced, including the drivers weight. The best way to get the weight is to weigh your vehicle at the track with the driver seated in racing position. Then click the calculate button and rear wheel horsepower will be displayed. To run another calculation just click the clear button and start over.
