Skip to content. The Horse Power Calculator below will calculate your approximate horsepower based on the vehicles weight, 1/4 mile time, and the 1/4 mile speed. Horsepower is a measure of the ability to move a certain amount of weight a certain distance, within a certain amount of time. If we were to make our example as a “poncelot” wheel, all the design parameters would be the same. The blades would not be straight. The unit is a relic from our horse-powered past. For all of the calculations simply fill in the yellow boxes and touch 'Calculate' The Horsepower Calculator will give HP from torque or torque from HP, HP with altitude change, Flywheel HP from Wheel HP, Wheel HP from Flywheel HP and Estimated Top Speed with Added HP. These calculations apply to “any” low-head waterwheel. Answers and Replies Related Other Physics Topics News on Phys.org. In the automotive aftermarket world, HP and Torque gains from tuning and upgrade parts are usually measured with chassis dyno testing. Calculate : Torque : Speed : Horsepower : Submit. The P42DC has a maximum speed of 110 mph (177 km/h). Use Calculator Pro’s 1/4 Mile Calculator in any location where you can get an Internet connection. From Torque OBD2 Wiki. Tractive effort is rated at 280.25 kN (63,000 lbf) of starting effort and 169 kN (38,000 lbf) of continuous effort at 38 mph (61.2 km/h) given wheel horsepower of 3,850 horsepower (2,870 kW). Rx7man, it often is better to run past the peak power curve for optimum acceleration. / (foot-lbs/sec) Constant = (62.42 / 550.221) Constant = 0.113491 . *Four-wheel drive cars lose between 20-25 percent of their quoted bhp figure because of the increased friction. Torque - HP. (Extremely averaged drivetrain losses) 5-speed front wheel drives (using a drivetrain loss of 13%) Horsepower at wheels calculation. Traction horsepower in HEP mode decreases to a bare minimum of 2,525 horsepower (1,880 kW) when providing the full 800 kW HEP load to the train. In simple words, the calculator tells you how much power your vehicle is producing approximately by using different Hp methods. These calculations apply to “any” overshot waterwheel. Horsepower and Torque can be measured quite accurately though the app "Torque" - measurements taken are 'at the wheels', not at the flywheel Setting up. Wheel, in the term “wheel horsepower and torque”, comes from the fact that they are values measured at the wheels of a vehicle. Engine RPM Calculation Basics. Get it! What is the difference between hp and whp? Horsepower formula is given as. One metric horsepower, whether written as pferdestärke (PS), cheval-vapeur (CH), or cavallo vapore (CV), differs from an imperial or standard horsepower due to how it was calculated. Video. Where did the constant come from. Racing calculators for determining horsepower, ET, MPH, converter slip, engine displacement and more. Horsepower Calculator From 1/8th Mile Stats: Wallace Racing BACK to Calculators Todays date is 2/11/2021 These equations are for recreation only. Whilst this all sounds very very boring, it’s pretty important to understand this when choosing a tuner based on their previous results as not all dynos are equal, and not all flywheel calculations are the same Enter the Weight and HP for ET and MPH, Then Press 'Enter' Key MPH = 234 * (HP / Weight) ^ .3333 ET = 1353 / MPH Weight Horsepower One Horsepower equals to 33,000 lb. Note the use of a crank in this system as opposed to a cams or gears. Sometimes it's better to use (less torque X lower gear) than (more torque X next higher gear). You can't "see" this instinctively from the power curve. The results of these calculato… Dewdrops on a spiderweb reveal the physics behind cell structures; By changing their shape, some bacteria can grow more resilient to antibiotics; New study investigates photonics for artificial intelligence and … Remember that shifting to a higher gear reduces torque multiplication. 1/4 mile Menu Toggle. With an 11-second car, we have 11-seconds to speed the wheel up. Home; 1/4 mile Menu Toggle. The only thing that changes among the various designs is the speed or dimensions. One of the most vital parameters of a car engine is its horsepower. So, our hypothetical wheel will produce 5.7 horsepower or 4.3 kilowatts. Horsepower. From "Stronger than a hundred men" by Reynolds . Calculate your potential gross horsepower. HorsePower = 2.577 . I have used Torque Pro App for sometime in my Hyundai i10 Era (2011 model) and it gives me Horsepower at wheels. In the same example above, the engine running at 5,000 rpm and producing 75 feet/pounds of torque is making 71.4 horsepower. 20 gauge or thicker is good. How I Calculate Horsepower from These information. True Horsepower - Effective HP scale - The I ... "True HP" is a term that signified that the rear wheel horsepower figure was derived from the actual power delivered to the drive roller - nothing added (except normal dyne system parasitic drag).
