With our combined expertise, capabilities, and inventories - we have the largest offering in the industry of remanufactured, aftermarket, and OEM hydraulic components and parts. Estimate horsepower output from any engine type (4-stroke, 2-stroke, any fuel type, turbo, blower, Wankel, etc.). Maximum "hull speed", in knots, is equal to about 1.3 X the square root of the waterline length of the hull in feet. Calculate the speed of the vehicle if its horsepower is 0.865 hp and torque is 250 pound-foot. The engine horsepower calculator gives you a couple of ways for estimating a vehicle's engine horsepower depending on its weight, speed and time to complete a run of quarter mile. By using this calculator, you get a quantifiable number on your vehicle's performance. Remember, if you are running E85 or Methanol be sure to use those BSFC values in your formula as well as the appropriate lb/gal conversion value for your chosen fuel.. To calculate peak fuel consumption for . If you are starting a bit more basically. Factor corrects horsepower for normally aspirated internal combustion engine to a standard humidity, pressure and . For converting HP to volts we have three sets of the formula for DC, AC single-phase and AC three-phase. It allows instantaneous power to be calculated and usually displayed as kW or BHP. How to calculate horsepower. This is a great tool for estimating carburetor or throttle body sizing to avoid going either too small or too big (which is a common mistake). A rough estimate of horsepower for displacement type hulls is fairly simple: 1. A dynamometer is a device that measures the torque and rotational speed (RPM) of an engine, motor or other rotating prime movers. This calculation is used to match oversize tires with new ring and pinion gears to obtain the desired engine RPM at highway speed. engine cfm - cubic feet per minute calculator. For example, if your engine has 350 horsepower then the torque would be 367 foot-pounds, at 5,000 RPM. Displacement = (4 in./2) x (4 in./2) x 3.1416 x 3.52 in.
