basic knowledge about vehicle engine

What is horsepower?· What horsepower is not is how much power your engine makes at high rpm… engines make horsepower everywhere within their operating range. Horsepower numbers are typically quoted at high rpms because the horsepower number is bigger than the torque number above 5,250 rpm and everyone wants to talk about the biggest number they can. 
· Horsepower is the work your engine performs… it is how quickly your engine can produce power. Think of it as how quickly you can turn a torque wrench at a given setting a dozen times rather than what the setting on the wrench for a single pull is.
· Because of the dense calibration sets in the Unichip your engine will make the most horsepower it’s capable of at every rpm.
What is torque?
· What torque is not is how much power your engine makes at low rpm… engines make torque everywhere within their operating range. Torque numbers are typically normally talked about lower in the rpm range because the torque value is always bigger than the bhp number below 5,250 rpm and everyone want to talk about the biggest number they can.
· Torque is the power your engine produces… it is literally the force your engine’s flywheel is experiencing and which is being transmitted through the vehicle’s driveline to the tires. Think of it as how hard you can twist a torque wrench on one pull.
· Because of the dense calibration sets in the Unichip your engine will make the most torque it’s capable of at every rpm.
