The answer to this question depends on the type of car you have. One universial answer would be to increase airflow to the engine. An engine must be able to "breath" and the better the airflow the more horse power (HP). Changing old airfilters will boost HP to some degree. You can also install high flow air intakes (depending on your car) and this will boost HP. Some gas addatives will also increase HP but they must be added with every tank of fuel and are not reliable. From the stand point of a Mini Cooper owner/driver the first modification I made was at the air intake to boost my HP.
cheapest way is cold air intake, after market performance exhaust with xpipe, headers and catback mufflers, new plenum, throttle body, performance chip, performance pulleys, and many more. What kind of car?
"Horsepower" is the way to measure the power output of car motor. The more horsepower a car motor has the faster it can turn the wheels and that would make the car faster on the road. Going faster than some other car on the road is a way males measure their manliness. It also increases the "adrenal rush" you feel doing something that can be dangerous.

Yes. Assuming the brake system is not damaged brakes can always stop a car faster than the engine can acellerate it. You can think of it this way. Brakes can generate more "negative horsepower" than an engine can generate positive horsepower.

One way to increase the horsepower of your car is to get rid of its stock muffler and replace it with a straight-through muffler. They are designed to keep the car quiet, but the rob it of horsepower. Another way is to buy an intake kit that will draw in the coldest air you can get.

When I was in the service, one way was intercity bus ( I don' t remember what they call it in Great Britain) but, for me, it was and I assume still is the cheapest way to 'get about,' as they say.
