Increase the Horsepower of Your 4 Cylinder Car

Not only can it run a wicked-fast lap around the Nordschleife, but the Civic Type R is in the 300-hp club. Its 2.0-liter turbo engine directs power to the front wheels by way of a six-speed manual transmission, and other racy upgrades include a triple-tip exhaust, adaptive dampers, performance brakes, and an upgraded interior with lots of carbon fiber accents. It should cost in the mid-$30K range when it goes on sale later this spring. We can wait to put it up against some of the other hot hatches on this list as soon as its available.

Experiment With Jet Size

Weve learned time and time again in dyno testing that jet swaps can go either way when it comes to power. Too much or too little can mean power losses, which is why its suggested you pick up a Holley jet kit and do a little experimenting. Go up one jet size at a time and see what you get, beginning first with primaries, then secondaries. Always better to err on the side of richer than leaner. If you lose power as you go richer, start going backward one jet size at a time. Go with a spark plug reading while youre at it right after a wide-open throttle shutdown to determine course of action.

If youre running a carburetor with a fuel line screen at the fuel bowl, remove it while youre in there. An in-line fuel filter is plenty enough and wont hinder fuel supply.

Engine Control Unit Flash

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 affordableand easiest to perform. Most ECU flashes reprogram the cars 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 cars stress threshold, an ECU flash can unlock a decent amount of power with little effort.

Computer Reprogramming And Chips

Reprogramming your vehicles computer can give you control over a host of settings like the fuel/air mixture, fuel injection timing, valve timing, spark timing and transmission shifts. Reflashing the settings can lead to gains in horsepower.

Changing the settings can be done by switching out the chip while in other cases you can reprogram the computer using an aftermarket scanner tool.

Implement A Cold Air Intake

How to Increase the Horsepower of Your 4 Cylinder Car

The science behind cold air intake systems is the principle that air increases in density as its temperature decreases. Denser air can burn the fuel better, increasing power. When you install a cold air intake system, it includes a new air filter. The new filter may look strange because it will be much larger than the stock air filter, up to three times larger.

Cold air intake systems also straighten out the path air follows to get to the engine. Curves cause the air to slow down and swirl as it moves through the turns. By removing the convolutions in the pipes, the system allows air to reach the engine more quickly.

    Fords turbocharged pony car easily outpowers its main rival, the Chevy Camaro Turbo, by 35 hp and 25 lb-ft of torque. The EcoBoost engine isnt as thrilling, in terms of power delivery and sound, as the 5.0-liter V8, but its plenty powerful to serve as the Mustangs base engine. Yes, thats right: For 2018, the Mustang will no longer offer its 3.7-liter V6. Then again, Ford data show that the EcoBoost mill already accounted for 38 percent of U.S. and Canada Mustang sales, compared to just 22 percent for the V6 and 40 percent for the V8.

    How To Build Performance In Four Cylinder Engines

    How to Increase the Horsepower of Your 4 Cylinder Car ...

    Building a performance four cylinder engine is much more difficult than building a six or eight cylinder engine because of displacement. Bigger engines simply transfer more air through the motor which results in high net horsepower and torque, thus the saying, “No replacement for displacement.” However, it is still possible to obtain decent results with a four cylinder motor with many techniques utilized in the motorsports industry.

    Step 1

    Install headers and a full catback exhaust system to allow the engine to breathe more freely. The stock exhaust is very restrictive on four cylinder engines, and a lot of horsepower can easily get freed up by simply installing a larger diameter exhaust system.

    Step 2

    Replace the intake tube and filter with a cold air intake. The stock air intake system is very restrictive it is designed this way to limit the amount of noise you hear under the hood. A cold air intake will re-route the intake hose to the front bumper where colder, denser air will be directed towards the motor. Denser air ultimately means more air in the engine and more power.

    Step 3

    Install aftermarket camshafts in the motor. The stock intake and exhaust camshafts are designed for a high miles per gallon figure and not for performance, which limits power and torque. Aftermarket camshafts allow the valves to remain open for a longer period of time, allowing more air to enter the engine to increase power.

    Step 4

    Step 5

    Increase The Compression Ratio

    The compression ratio refers to the volume of the cylinder when the piston is at the bottom of its stroke versus the volume of the cylinder when the piston is at the top of its stroke. when the compression ratio increases, then a higher octane fuel is needed. Higher octane fuels will not combust too early. This is the reason why most high-performance vehicles require high octane fuel and this, in turn, will improve a cars engine.

    Yes, yes, the purists whined when Porsche announced it would turbocharge its engines. But when even the base Cayman and Boxster produce more than 300 hp, is there much to quibble about? After all, these engines produce far more torque than the previous naturally aspirated versions, and Porsches mid-engined cars remains an absolute joy to drive, turbo or not.

    Use Synthetic Lubricants And Additives

    Increase the horsepower of a 4 cylinder engine

    Motor oil comes in conventional, synthetic and blend varieties. For longevity, durability and all-temperature use, choose synthetic. Synthetic lubricants have a chemical structure that allows them to perform better in your engine, offering superior lubrication over conventional oils. Conventional oils can break down too soon when the motor gets too hot, but synthetic oils dont. Because they lubricate surfaces better in all temperatures and driving conditions, synthetic oils are a better choice for high mileage and performance vehicles.

    To further improve the performance of whatever oil you use, use a proven additive with your oil, like the super-advanced Rislone Nano Prime Engine + Oil Performance Booster. This synthetic-formula additive cuts down on engine friction, which reduces heat, allowing it to run harder and longer with less damage. Its structure even enables it to repair small pits in the metal components of your engine. Unlike other oil additives that use bearing-damaging chlorine, Nano Prime does not have this ingredient, opting instead to use a patented formula that protects rather than harms your engine.

    Replace Your Exhaust Manifold With Real Headers

    Getting exhaust away from your engine block and out of your vehicle is an essential piece of the power puzzle. The manifolds are interconnected tubes that direct exhaust from each cylinder to a single outlet. The problem with manifolds is their design. Backpressure from hot exhaust reducing outflow can reduce power. However, if you replace the manifolds with exhaust headers, you will eliminate this problem. Headers pull exhaust away from each cylinder individually. Only after the pipes are away from the engine do they funnel together into a single collector. Most vehicle manufacturers install manifolds because they cost less to build and install. Lower costs sacrifice engine peak ability.

    Replacing the manifold with exhaust headers is a bolt-on task generally those with intermediate skills can accomplish. If you have already done everything possible and still want to draw more power from your engine, install exhaust headers. You will get rid of backpressure and help your engine become more efficient by replacing the manifold.
