One-thousand horsepower, four-cylinder<\/a> engines are today\u2019s reality in import drag racing. This reality includes the leading-edge forced induction<\/a> and engine-management<\/a> technologies that make power production the easy part of building a racecar<\/a>. Today\u2019s performance engines are running at higher boost pressure levels and higher compression ratios than ever before. Understanding how both compression ratios and boost pressures affect performance is a key to maximizing performance from your street or race vehicle.<\/p>\n

4-stroke Engine Basics<\/h2>\n

Without going into a lengthy explanation of internal combustion engine<\/a> dynamics, your vehicle\u2019s engine is a machine designed for energy conversion. Using a four-stroke cycle<\/a>, a fuel-and-air mixing strategy and a spark for ignition, the internal combustion engine\u2019s first task is to convert the chemical energy stored in the fuel into thermal energy (heat) through a process called combustion. The engine\u2019s second task is to convert this thermal energy into kinetic energy in the form of horsepower at the flywheel. How well an engine can convert the heat (thermal energy) into power (kinetic energy) is quantified by an engine\u2019s thermal efficiency. An engine\u2019s thermal efficiency is highly influenced by the engines static compression ratio. <\/p>\n
