How to Increase Power in Naturally Aspirated Engines?

[SanKennedy]

Methods to enhance power in naturally aspirated engines are as follows: 1. Use a high-flow air filter to smooth the intake tract. 2. Modify with a direct throttle body. 3. Improve the efficiency of the intake and exhaust systems, such as altering the cam profile or even using an electro-hydraulic camless valvetrain to extend valve lift and duration. 4. Adjust the parameters of the electronic control system to boost power. 5. Use high-energy, stable spark plugs, high-quality gasoline, and reduce vehicle weight to gain some power. 6. Lower the intake air temperature. The principle behind lowering intake air temperature is that colder air is denser, allowing more mass of air to be drawn into the engine cylinders for mixing with fuel, leading to more complete combustion and thus greater energy output.
