Basic engine tuning

as you all know about how the engine works, tuning it to make it work better and faster means adding more air and fuel. But to do that needs more money, time, and effort. these are some basic tuning ways to make your engine move faster and more powerful.

Making bigger inlet and exhaust valves- bigger inlet and exhaust valves which means ports being machined to a "better" shape. so more air and fuel can go into the combustion chamber to be burned and also better escape of exhaust gasses.

Bigger pistons- bigger pistons makes the cc of the engine bigger. for example, an engine of a 1.6 litter being bored and fitted with a bigger piston to make it to a 1.8 litter engine. by making an engine with a higher engine capacity can make more horsepower.

Tuned exhaust and intake manifolds- with a tuned exhaust and intake manifold, will increase horsepower of an engine. because the engine can breath better and remove the exhaust gas better too. a well tuned intake manifold can make better air flow for each individual cylinder which allows more air and fuel to enter. this increases the volumetric efficiency of the engine. this also applies to the exhaust manifold which improves better escape of exhaust gasses.

Lightening parts- lightening your motor parts like the flywheel and crankshaft can contribute to more acceleration especially in lower gears. this is because less energy is being used to move these rotating parts. but it will not increase horsepower of the engine.

if there is more you would like to share or questions, feel free to post a comment. would like to hear it.

engine 4 stroke cycle

In order to increase the horsepower of an engine is to first understand the four stroke cycle within the engine. The four stroke cycle consists of intake stroke, compression stroke, power stroke, and exhaust stroke.

Intake stroke

The first stroke is the intake stroke. The piston

moves down the cylinder and creates a partial

vacuum in the cylinder. A mixture of air and fuel

is forced through the inlet valve into the cylinder

by atmospheric pressure, now greater than the

pressure in the cylinder. During this stroke,

the exhaust valve stays closed.



Compression stroke

The second stroke is the compression stroke.

The piston moves up in the cylinder with both

valves closed. The air and fuel mixture is

compressed and the pressure rises.



Power Stroke

The third stroke is the power stroke.

Near the end of the compression stroke,

the air and fuel mixture is ignited by an

electric spark from the spark plug. The

combustion that occurs causes a rise in

temperature and enough pressure to force

the piston down again



Exhaust Stroke

The fourth stroke, or exhaust stroke, the

piston moves up again and forces the burned

gases out of the cylinder and into the exhaust system.

Make your power window smooth


With any vehicle which has power windows or manual windows, it is best to spray silicon on the sides of the windows guides. This guide are located on the sides of the glass (marked in red circles) . Just spray into the guide and let the silicon liquid flow down. Hope it helps
