These Are the Easiest Ways to Get More Horsepower Out of Your Car

Don’t have a team of mechanical engineers at your disposal to power up your ride? These five methods can pull more power on the cheap and easy.

Mustang-GT500-Gear-Patrol-slide-3

Legend has it motorsports were invented the moment the second car rolled onto the streets. No matter when automobile racing started, though, mechanics and engineers have been on the hunt for more power ever since, trying to one-up the competition—or just get a stronger hit of speed.

While big manufacturers have the resources to support massive R&D teams who tear apart engines in search of more horsepower, the average Joe Six-Cylinder working out of his garage does not. For folks like that—presumably including you, dear reader—less labor-intensive, more affordable methods of squeezing become the most attractive.

To help in your pursuit of power, we at Gear Patrol have pulled together some of the easiest ways to get more horses out of your car…if, you know, you don’t have a team of engineers at your disposal.

Engine Control Unit (ECU) Flash

Upgrade-Your-Ride-Gear-Patrol-ECU

“Chipping,” or flashing the engine control unit of your car, is akin to teaching its brain new tricks. Of all the ways to eke out a few more horses, this might be the most affordable—and easiest to perform. Most ECU flashes reprogram the car’s onboard computer by altering the fuel-air mixture ratio to a more aggressive setting; since most original ECU settings are programmed for efficiency and sit well below the car’s stress threshold, an ECU flash can unlock a decent amount of power with little effort.

Cold Air Intake

Upgrades-to-Breathe-Life-Into-Your-Old-Ride-gear-patrol-Intake

Cold air intake systems simply replace a car’s stock air filter and intake. Engines need to breathe just like people do; the idea behind a cold air intake is that it increases the flow of air going into the engine, and doesn’t regulate the temperature the way some OEM intakes would. (The colder the air, the denser it is—and therefore, you get more air feeding the combustion process.)

Exhaust

Upgrade-Your-Ride-Gear-Patrol-Exhaust

Swapping exhaust systems is a little more involved—especially depending on how much of the exhaust you’re replacing. It can be a simple as removing the muffler at the back; more involved in the form of replacing the piping rearward from the catalytic converter (known as a cat-back system); or doing the whole shebang and replacing the everything from the headers to the exhaust tips. Some might think replacing an exhaust system only amps up the engine sound, but a complete upgrade also unlocks power by letting the engine empty burned fuel and gases quicker and more cleanly.

Supercharger

Edelbrock-Supercharger-Gear-Patrol

The search for horsepower becomes more complicated when you start dealing with forced induction systems (superchargers and turbochargers), but the mods are still manageable in a home garage. The most common superchargers use a belt system, in which a belt connects the engine’s crankshaft to the impellers of the supercharger, spinning them and compressing air that’s then fed air into the engine. (Remember, the more dense the air, the more power you can make.) With that direct connection, the supercharger’s power delivery is relatively constant, no matter the engine speed. However, the air heats up when it’s compressed; if you’re going the supercharger route, an extra radiator or intercooler is recommended.

Turbocharger

Garrett-Turbo-Gear-Patrol

Turbochargers, like superchargers, are a form of forced induction; unlike superchargers, however, turbos use a compressor powered by a turbine which is spun by gases flowing out of the engine. The lack of direct connection to the crankshaft can lead to a delay in power as the compressor builds up speed—this is known as “turbo lag”—but overall, turbos are more efficient than superchargers, as they’re powered by a waste product instead of sucking power off the engine.
