Daniel Bernoulli and why he should matter to you

Daniel Bernoulli was a mathematician and physicist who specialized in fluid mechanics... the study of the effects of forces and energy on liquids and gasses. Why should this matter to you? Because air is a gas and exhaust is a gas and the mechanical principles on how gasses impact how your car performs is directly related to these two gasses. This article discusses the impact of aerodynamic principles on your car and your exhaust system.

What is Horsepower and Why Doesn’t it Tell the Whole Story?

A horsepower (HP) is a unit of power that was created to compare the power output of steam engines with the power of draft horses. Yes... that's right, steam engines and horses. It is derived by taking the torque produced by an engine, multiplying it by the RPM and dividing that by 5252. In theory, this number could produce a number that could be used to cross compare different engines on a level playing field.
