This isn't your ordinary dyno cell. Although every engine is broken inand checked for power on a dyno before it leaves the shop, this Dyno-Simis a special tool reserved for R&D. It is computer controlled and cansimulate an entire race, including practice, qualifying, and even pitstops. It is used to test how new parts will act under racing conditionswithout risking a team's performance in a real race. Interestingly, thisdyno uses electrical resistors instead of water to create drag on theengine. It produces so much electricity during a test session--which canlast up to four hours or more--that RCR actually sells electricity backto the local power company.
