Cubic Inches = Bore x Bore X Stroke X Number of Cylinders X . Look at it this way: if there was just one formula, how could the '60's Chevy 327's make a different range of horsepowers between 250 and 375? Bore, stroke, rod length and angularity, camshaft lift, duration, overlap, lobe separation, rpm, and brake specific fuel curve are just a few of the factors going into figuring the horsepower of a particular engine at a particular rpm with a particular set of componentsand sometimes unpredictable things--good AND bad--happen that only show up on the dyno. form.rpm13.value = ""; Go back to my other post where it said 1/4HP per cu" at 1800rpm for a diesel. calculete cubic inches from different unit, engine horsepower. for (var i = 0; i < str.length; i++) { The cubic inches of an engine is the measure of the swept volume of all of the pistons in the bores, not including the combustion chamber itself. n3 = a * a * 12.87 * e newValue = newValue / 100 Horsepower is a measure of the ability to move a certain amount of weight a certain distance, within a certain amount of time. } our A is 360 cubesand we had 57horse. About 1/2HP per cu for a plain boring carburated engine and 1/3 HP/cu for a a plain boring injected emissions engine. I sure can't think of any that make that . "url": "https://www.yesterdaystractors.com/graphics/smllogo.png", CC tells you the usable volume that an engine has for combustion. { form.quarter3.value = findquarter3(form); }, Over time engines will lose horsepower as the engines parts and material wear. Since electric cars don't have combustion engine, there is no cubic meters that can be measured in them. Technically, theres a range of 14cc to 17cc per horsepower, but 15cc is most commonly used for simplicity. { var c = parseFloat(form.heads.value); { function computeForm(form) { But its certainly close enough to give you a good idea! cubic foot to cubic inches. return formatvalue((form.newheight12.value / form.oldheight12.value) * form.origratio12.value, form.rsize); var ch = str.substring(i, i + 1) These gross horsepower figures came from engine dyno results in which the tested engine had no real-world accessories attached such as power steering pumps, smog pumps, and or A/C compressors. There are tooltips over each input to tell you which values are affected by this input. A 16 horsepower engine is approximately 240 cc. So you have to figure Displacement and RPM's to figure HP. Disclaimer: } } } Gasoline two valve per cylinder engines are considered built to the max for easy drivability and use of pump gas at 1HP per cu" at 5500rpm. alert(msg + " not in range [" + min + ".." + max + "]"); Horsepower is not recognized in the International System of Units (SI); SI uses a measurement of power (a rate at which energy is generated or used) called a watt, which is named after James Watt. include inches, feet, yards, mm, cm or meter, "height": 57 The following equation can be used to convert a CC to HP of a typical combustion ending. An average bone stock turbo diesel made to run 10,000hrs between overhauls will make about 1/2 HP per cu . We also have a calculator that lets you model changes in horsepower. Energy is often presented using units of kilowatt hours (kWh), usually within the context of electric utilities delivering energy to household consumers. This tool can also be used to find the final engine size based on any bore size, crankshaft stroke and number of cylinders. form.quarter3.value = ""; engine horsepower calculator Home engine horsepower calculator This calculator gives the baseline horsepower and cubic feet per minute (cfm) that an engine will develop at its maximum rpm given the volumetric efficiency of the engine. { function findstrtcarb13(form) if (!checkNumber(form.bore, .00001, 99, "Bore") || !checkNumber(form.stroke, .0001, 99, " Stroke") || !checkNumber(form.heads, 0, 200, "Heads") || !checkNumber(form.gt, .0001, 1, "Gasket Thickness") || !checkNumber(form.dt, .0001, 1, "Deck Thickness") || !checkNumber(form.cylinders, 1, 12, "Number of Cylinders")) { { Choose cam tappet type: Flat Tappet Roller Enter your DYNAMIC compression ratio: :1 (Not your typical STATIC compression number, if you don't know this you can calculate it here ) Enter your engine displacement (cubic inches): Enter how many cylinders: 4 5 6 8 10 High Performance starts with math, precise measurements and calculations. A super stock 4 turbo set-up makes more than 5 H.P. { This calculator can be used to compute horsepower according to its definition and to convert between different power units. { if (x==7) Has more to do with amount of air at atmospheric pressure that you can pump through the motor in a given amount of time. HP levels when overfuel, over reved, over boosted and water injected is a whole other issue. { function update(form, x) In reality there is far more to it then CID. var rounded = "" + (fltin + (fltin - parseFloat(strin.substring(0, rsize)))); Lets use an example where weve got a 75 HP engine. A 5-horsepower engine is approximately 75 cc. in the engine.No wonder nobody pulls against him. This calculator determines the displacement size of an engine, based on your data, in cubic inches and CCs. form.conv4.value = ""; 1/2 hp per cu inch for a stock NA diesel? This calculator will help you estimate the potential of an engine. var n4 = 0; { the unit is cm, and we need calculate the cubic inches. var n6 = 0; form.height10.value = findheight10(form); Writing Excel Macros with VBA. if(x==4) Go back to my other post where it said 1/4HP per cu at 1800rpm for a diesel. function findhp0(form) A 1500 cc engine is approximately 100 horsepower. HP stands for horsepower. Also these power figures were typically attained with a very unrestrictive open exhaust system, along with the lack of restrictive OE air cleaner assemblies. { form.eqratio12.value = ""; The horsepower winner here is easy to see, and automotive marketers have taught us that horsepower and cubic inches have always gone hand-in-hand. The formula for calculating the horsepower from these values is HP = t*RPM / 5252. } var str = input.value; Enter the cylinder bore diameter. form.widthmm10.value = ""; 1/3HP per cu for turbo and 1/2HP per cu for turbo intercooled. Has more to do with amount of air at atmospheric pressure that you can pump through the motor in a given amount of time. } Although horsepower is an important metric for doing so, it should not be the only consideration in determining a vehicle's ability as there are other factors such as power-to-weight ratio, torque, drivetrain, and forced induction. { There's no magic formula to convert cubic inches to horsepower. Because 1,000 cc is equal to 1 liter, you may also see engine sizes described in liters as well. form.diameter11.value = ""; Check or Compare the potential earnings of your hardware. if(x==3) n7 = n4 + n6 fill the blanks of lenght, width and height, choose the unit of measure you are using (in,ft,yd,mm,cm,m), then you will know how many is the cubic inches(in), 13.78 10.236 8.661 = 1221.6520649 in, 1 mm = 0.1 cm = 1/25.4 inches = 0.0393700787 inches. The dynamometer will measure both the torque output and the RPM (revolutions per minute) of the engine and then it calculates the horsepower from those values. Use of the calculators within this website is free. n4 = n2 + n3 + c - f form.mph6.value = ""; 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. n8 = n7 / n4 } Free Horsepower Calculator Engine Rear Wheel Horsepower Calculator Based on total vehicle weight and 1/4 mile MPH To use this horsepower calculator enter the mph trap speed at the 1/4 mile mark from one of your dragstrip ET slips.
