does more horsepower mean faster acceleration?
Given their interchangeability in regular conversation, as well as the horsepower vs. torque debate, we thought it necessary to put this issue to rest once and for all. If you were to try and start in 4th-gear (usually 1:1) you wouldn’t have the mechanical advantage provided by the torque manipulation, and thus would stall your engine since it can’t push hard enough. Why don’t Formula 1 cars have torque?

Eventually you’ll reach a point where the power your engine provides can no longer overcome the forces of drag, and you won’t be able to go any faster. So how should you make your car faster, and what actually makes cars faster? Join Yahoo Answers and get 100 points today. But like Formula 1 cars, they don’t really need torque, they are designed to remain at very high rpms and very high speeds, like you’d find on a track. But really, horsepower came about as a Scottish engineer by the name of James Watt was looking to compare the output of steam engines and draft horses in order to sell people on his steam power business—yay greed!

Also, OHC designs allow for faster camshaft speeds since there’s multiple camshafts rather than one.(4.) Whether in Horsepower, Kilowatts, or that weird German unit for Horsepower, Power is what matters for pure speed. Well, it’s simple multiplication:100 x 3 x 2.75 = 825 lb-ft of torqueIn real life you’d multiply this by a frictional constant (usually 0.85 assuming 15% frictional losses) to find the torque going to the wheels and then if there are two driven wheels with an open diff (each wheel gets half the torque) you’d multiply that number by a half. TL:DR, pound-feet refers to the force applied and exerted by a car’s wheels as it bites the pavement. But can it take it........I long do you expect a 2000 HP Honda engine to last before it throws a piston through the hood or oil pan? 1. Here’s the math for you lovers of equations! Here’s what they all mean and why they’re used. A: Depends, do you like schlocky Fast and the Furious rip-offs with motorcycles and a scene where a turbine-powered superbike called the “Y2K” enters warp speed? A newton-meter is a unit of torque in the metric system and one foot-pound is equal to 0.73756 newton-meters. Suspension depends on the car, My car is touted as having a horrible suspension but because its all wheel drive it doesn't matter to me. The difference is torque is doing the work, while horsepower is how fast that work is being done. Recall that acceleration is: So if our goal is maximum acceleration, you can go about it two ways: Either increase the Force (torque) applied by the engine and transmission, or decrease the mass the engine has to move (your car). Horsepower is the most commonly used figure to denote a car’s power and most often relates to how much power a car’s engine develops at the crank of an engine, not at the tires. I have been told a lighter vehicle would get you down the drag strip or roadway more efficiently too. When it comes to acceleration, really power doesn’t matter all that much. Notice in the old Formula 1 engine crank I posted below how short the strokes are. Deep strokes allow for greater compression and thus more torque, but shallow strokes mean the piston has to move less far and thus can obtain higher piston speeds. construction, so that there is less reciprocating mass to impede on higher piston velocities. So a turbocharged 2.0L engine theoretically now has as much displacement and torque as a 4.0L. For example, cruise ships have a huge amount of Horsepower, sometimes in the hundreds of thousands, but since there’s so much weight/drag to move against they can only keep going so fast.Toque/weight is a much more accurate way to compare car’s acceleration abilities, assuming both cars have similar structures. Good oil lubrication, since higher engine speeds demand more lubrication.(3.) A: Well, the auto industry tried that, and...yeah.
