Car enthusiasts are often more eager to improve gas mileage and keep maintenance costs low than to maximize performance hence choosing for the economy which
is quite natural. That means most cars are born with the equivalent of a stuffy nose. Below are the ways to increase horsepower.
1. Upgrade to a free-flow aftermarket air filter.
* Buy a free-flow air filter that best fits your car.
* Open hood. Locate the air filter housing. which is the long pipe connecting the engine to a
square plastic box.
* Remove housing.You must ake sure that no dust enters into the filter housing.
* Remove the old filter but make sure that you remember that how it was fitted because you
will have to fit a new one.
* Take a slightly moist cloth and clean the inside of the box.
* Insert the new filter.
* Close housing box and thats it you are done.
2. Upgrade your engine's computer with a power module.
* Disconnect negative battery cable.
* Locate the car's computer.If unable to access car's computer seek guidance from your car
manual.
* Kill the computer's power by unplugging it.
* Plug in an after-market power module. Insert it between the wiring harness and the computer.
* Reconnect negative battery cable.
* Follow the module's instructions for starting car.
* Refill your car up with fuel and race with up to 30 extra ponies.
3. Upgrade your car's computer with a programmer.
* Programming devices modify or in other words upgrade the programming on your vehicle's
computer,allowing more horsepower, torque, and sometimes better fuel economy.
* After you purchase such device for your vehicle, read the instructions manual to install it.Each
programmers has its own way to install and work,so reading the manual is the only safe and
good option.
4. Upgrade to a free flowing exhaust
* First, determine the exhaust piping diameter of your exhaust.I repeat it measure the
diameter of the exhaust I repeat it measure the diameter of exhaust piping do not just
measure the diameter of your exhaust tip. Measure the pipe that comes out of your catalytic
converter,as its usually the smallest.
* Search online or in a store for a performance exhaust system for your car.Some online videos
on youtube or other sites may make your car sound appealing
* You'll have to find a "cat back" system. which run from catalytic converter to the end of the
exhaust piping.
* Go for a system that is 1/4 to 1/2 inches LARGER than the one your car came with from the
factory.More larger system may require dramatic modification to the engine.
* TOO free flowing exhaust can have a negative impact on low end torque, so you'll probably
want 1/4 inch for a 4 cylinder, 3/8 for a six and 1/2 for a v8.
* Cut the old system out yourself,and cut it just after the catalytic converter and leave an inch or
two to clamp or weld onto.Detach the rest of the exhaust system from the hangars.
* Position the new system in place (assuming you've assembled it) and weld or clamp it to the
spot you just cut. Reinstall the hangers that you removed.
* Start the car and feel the energy of a good 10-15 hp increase.
