We found
out previously that to make more power we cant just add more fuel!
We need to make our engine breath more air. Then we CAN add more
fuel and there will be enough oxygen to burn it!
So, how can we do this then?
1.
We can use
conventional
tuning methods???
The engine has pistons that draw in air (oxygen is the important bit)
and push out exhaust gasses through the ports in the cylinder head, and
the valves above the pistons.

The air has a torturous path, from the outside, through the air filter box, through the inlet manifold, and past the intake valve in the engine and into the cylinder. It has an equally difficult time getting out! Another valve, an exhaust system etc. If we improve the gas flow through all of these parts at once, we will get MORE power. Doing only SOME of this work will seldom give a power increase. In any case unless SERIOUS money is spent, and lots of work, its almost impossible to get much more power. "Conventional" or traditional tuning is pretty limited. It usually means bigger inlet and exhaust valves, and ports being machined to a "better" shape, higher compression ratio, bigger carbs, etc. This normally means a horrible to drive, short lived revvy motor that drinks fuel!
2. We
can "Chip"
some cars
3.
Aftermarket
Turbo charging
3. Supercharging
your road car!
4.
Nitrous Oxide injection (Incorrectly called NOS by hundreds
of boy racers that watched the Fast and the Furious!!!)
