With the jostling and bumping that occur, it is sometimes easy to forget that at its heart Stock Car racing is an endurance event.
Top NASCAR teams work to ensure reliability for every race on every component.

Each part is designed to ensure that 400 or 500 miles pass without incident. If there is a component that does show problems or appears to be a liability the challenge must be met with swift and decisive action.

Alternators are one of the most problem-prone parts on NASCAR race engines.
The combination of high under-hood temperatures (up to 350F), high vibration (up to 600g), and high electrical current demand (up to 140A) present unprecedented design challenges.

A meeting with CRP at the first edition of MotorsportExpotech in 2008 in Italy gave Dr. Andrew Randolph, Engine Technical Director for Earnhardt Childress Racing (ECR), another option for this type of challenge.
