This web app uses the quarter mile distance or track. It turns out to be amazingly low — only about 20 hp. But weight is … Trap speed is the velocity or speed of a vehicle at the end of a run or race competition. This calculator computes the estimated engine or motor horsepower from trap speed. For all you geeks out there powering our tech progress, here’s a cool way to calculate the horsepower you need to cruise at 65 mph on the flat — thanks to Peter Offenhartz. But most cars with 1000 hp cant go 500 mph, maybe 190mph or so. 50 km/h to mph = 31.06856 mph. Try out this calculator get a rough estimate of horsepower. 5 km/h to mph = 3.10686 mph. Note: This is a rough and quick estimate of engine horsepower. the 1,500-horsepower Bugatti Chiron and its 300-mph top speed. It takes almost 197 HP to be able to run to 150 MPH. Depends on how much hp (horsepower) the car has that goes 500 mph. So, if your car only makes 180 HP, you won't be able to get to 150 MPH. Since he does not really explain why his method works, here’s the trick. 75 km/h to mph = 46.60284 mph. 1 km/h to mph = 0.62137 mph. 40 km/h to mph = 24.85485 mph. So here's the deal (using customary U.S.A. /British units) a.k.a. But an additional 300 horsepower might not gain another 20 mph. {\displaystyle P[{\text{hp}}]={\frac {F[{\text{lbf}}]\times v[{\text{mph}}]}{375}}.} The Trick. the first 300 mph might very well get it to 180 mph. Brake horsepower – or bhp – is the most widely used measure of engine power alongside PS (see below), although it's often not clear which unit manufacturers are using in their brochures. 20 km/h to mph = 12.42742 mph. Well to begin with that’s really not answerable in any way shape or form think about this if three hundred horsepower would take a dragster to 180 mph then you would easily be led to believe that 600 would take it to 360 mph but in reality it just doesn’t work that way at all. Air Drag Coefficients and Frontal Area Calculation ›› Quick conversion chart of km/h to mph. If the drawbar force is measured in pounds-force (lbf) and speed is measured in miles per hour (mph), then the drawbar power in horsepower (hp) is P [ hp ] = F [ lbf ] × v [ mph ] 375 . 10 km/h to mph = 6.21371 mph. 30 km/h to mph = 18.64114 mph. 100 km/h to mph = 62.13712 mph ›› The more horsepower you have at your disposal, the faster you’ll be able to push your theoretical car in terms of top speed, i.e.
