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.
Okay... so you broke/bent an endlink and you have to detach your swaybar to keep things from thunking around. You drive around for a bit and you don't notice any difference... what's going on?

How many times have we seen this question asked? The resounding answer to that question is “NO”, but have you ever stopped to wonder why the answer is no? What is octane and why can I tune for higher power levels because of it? What will happen if I use a lower octane fuel than […]
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.
