Air density is one of the most overlooked factors in making power. Engine displacement, big turbos, large head ports and high lift cams only maximize air flow when the volume of air is at its highest. We at Fine Line Imports have put together some useful information regarding the effect of air density on engine power, gained through our own research and test runs performed in our dyno room over the past 3 years. All data shown in this article was logged at the time of the actual dyno run.
Temperature, humidity and altitude are major factors that need to be addressed when trying to achieve maximum engine power. Fuel quality, tuning and the level of volumetric efficiency (“VE”) of the engine also play important roles. VE is an important factor that will not be discussed in this article. This article will only address the topic of air density.
