Why do European cars have more horsepower?
Horsepower is torque times engine speed. European motors tend to have smaller engines (less torque) that rev high (more horsepower). Many countries that are not America tax cars by their displacement. This leads to engineering around this restriction to output the same horsepower with less displacement.
What adds more horsepower?
NITROUS OXIDE (NOS) A nitrous oxide kit can add A LOT of horsepower and torque to an engine. A nitrous oxide kit can add anywhere from 50-500 horsepower, depending on the size of a nitrous oxide kit.
Why do some cars have more torque than HP?
Basically, the faster the crankshaft spins with the same amount of force, the more power an engine will make. A car with more hp than torque will always be quicker since this gives a car acceleration and speed.
What does extra horsepower do?
Generally speaking, the more horsepower a car produces, the better its acceleration, which is a strong factor in its overall performance. The more torque a car has, the better it can accelerate from a stop and the more strength it has for towing.
Why are North American cars so big?
But Kennedy also believes Americans buy larger cars because the nation’s roads and highway system have grown large enough to accommodate them, which isn’t always the case overseas. “In Europe and other areas there are very old infrastructure and small streets in five- to seven-hundred-year-old cities,” said Kennedy.
Why are there no American cars in Europe?
Europeans don’t buy American cars because they don’t like their huge size and appetite for gasoline, not because of import duties. The US charges only 2.5 percent duty on imported brands like BMW, Mercedes Benz and Volkswagen, while Europe imposes a 10 percent duty on imports.
Does cold air intake increase horsepower?
Cold air intake systems can increase horsepower by replacing the restrictive stock intake, with components that are designed to handle a much larger volume of air. This allows a K&N cold air intake system to boost performance, by simply improving on the factory design.
How much horsepower does an exhaust add?
The Most You Can Gain is 2-5\% If you want to know how much power you can expect to gain from adding an exhaust system to your car, assume that your engine will get 2-5\% more powerful. More specifically, large engines like a big 6.0L V8 typically see about a 2\%-3\% horsepower increase.
How much HP does supercharger add?
How much horsepower will a supercharger add? Connecting your supercharger to the engine intake can add around 50-100 horsepower. On the other hand, a turbocharger can add around 70-150 horsepower.
