NASCAR Holley Fuel Injected Engines on the Dyno

From http://www.horsepowermonster.com/
After racing Holley carburetors for decades, NASCAR recently made the switch to fuel injection beginning with the 2012 season. But even with all the changes to the engines, Holley still plays a pivotal role in making these engines perform. The engine builders at Roush Yates Engines and ECR gave us a behind-the-scenes look at what's involved and how Holley makes it happen. This is a video I produced for Holley taking a look at their new billet throttle body.
