During the inaugural Engine Performance Expo, technical difficulties prevented the completion of Ben Strader’s anatomy of a Holley carburetor compared to a Holley throttle body EFI system. We’ve found the missing footage, so we pick up where the video glitched.

Ben was talking about the different parts of the metering block (the brain of the carburetor). From there Ben completes the comparison of the fuel delivery systems and then shows the dyno comparison of the two systems. The first dyno run is the Holley EFI system. The second dyno run is the Holley carburetor. Stay tuned to the very end to see the results for yourself!
