Some DYI Methods On How To Improve The Car’s Overall Horsepower
In a lot consisting of car buyers, there are some who aren’t happy with the stock performance of the car and look for a chance to upgrade it whenever they want to. However, getting the right idea or configuration isn’t always a piece of cake. This is because either the person doesn’t have an update about what all can be done or the mechanic/garage they went to, is charging them a lot more than expected.
An easy way of improving the car’s performance is by increasing the horsepower.
Car Performance Parts For Increasing Horsepower
For achieving better results and to increase the car’s horsepower using the bolt-on performance parts, it is imperative that these parts work together. It is generally recommended that a person get expert advice about the parts that can be best combined for your vehicle, and if there is only one modification that can be carried out, then the order of installation.
A few bolt-on engine modifications are needed for getting more horsepower as well as torque, effectively getting improved acceleration, increased tow capacity and quicker passing.
If a person understands how to improve the horsepower, they can effectively unleash the full potential of the car and improve car’s efficiency leading to more savings from the increased mileage.
A Plan To Follow For Increasing The Car’s Horsepower
- Make a switch to a performance Air Filter: For improving the efficiency and the horsepower, more air and fuel is required to get in and out of the engine. Making a switch to performance air filter allows a lot more air to freely flow to the engine.
- Input a Cold Air Intake System: A cold air system will cause more outside air(cooler air) to have access to the engine. Since colder air is generally denser, it does help make more power.
- Add Cat-Back Exhaust Systems and Performance Headers: For moving more air out of the car’s engine, a higher performance, cat-back exhaust system mated with performance exhaust headers adds power by reduction of back pressure in the car’s exhaust. However, if you wish to install headers, make sure you understand that you know what you are doing as this is a high-level work which involves partially pulling the engine and removing a lot of parts.
- Upgrade to the use of an Electronic Ignition Kit: An aftermarket car ignition system will allow the vehicle to have a hotter spark. The use of an electronic ignition kit furthermore eliminates the breaker point present on older vehicles. Although, for vehicles that have no distributors, hotter coil-on-pack ignitions have been made available.
- Change the Car’s Fuel Delivery System: In vehicles that incorporate fuel-injection, there’s not much left to be done. However, for older vehicles that have a carburetor, there can be a major difference in performance if an aftermarket carburetor is used. One may also consider the phenolic riser that puts the carburetor around an inch over the intake manifold.
The idea of using a high-rise competition manifold or a riser is more velocity generation through the use of air/fuel mixture and puts the carburetor at a farther away from the engine’s heat so it is able to mix cooler air along with the fuel.
- Recurve the Distributor: In older vehicles that possess mechanically advanced distributors, ‘recurving the distributor’ stands for installation of lighter springs and resetting the timing so the distributor will advance the spark at the lower RPM ranges. *This is a tricky procedure and might require trial and error in some form, apart from a good timing light as well as all the right tools.
- Fine-tune and Reprogram the Computer Controlled Systems: Vehicles that have computer-controlled engines can be fine-tuned using a hand-held reprogrammer that helps advance timing, change shift points(on Automatic Transmission and optimize fuel delivery. However, make sure you are guided about this as any small or drastic change in the car’s engine performance guidelines is needless to say, tricky.
- Install Under Drive Pulleys: The usage of under drive pulleys as accessories leads to a reduced parasitic drag on the car’s engine and frees up some more horsepower.
Power VS Weight
At the end of it, performance does depend upon power vs weight. This can be seen from the fact that a four cylinder turbocharged sports compact will able to go beyond most mid-sized V8s. Similarly, a turbo diesel pickup can out do most gas engines in the similar size and still get twice as much fuel mileage.
On the other end, an inter-cooled/turbocharged 2.0L Mitsubishi has a lot of engine horsepower. A 2.0 L engine may do wonders for a tiny Mitsubishi Lancer, but the same won’t seem like much of a power for an SUV.
Torque VS Horsepower
Also important to understand is the relationship between horsepower and torque. Automakers brag about the total output of the engine in horsepower numbers, however, engine torque is what necessarily accelerates the vehicle. it is important to properly match the engine’s torque curve with the vehicle.
