NASCAR teams develop their lightning-fast pit-stop prowess the same way all top athletes sharpen their skills to championship form – hard, diligent training. But these jack-wielding warriors can’t put practice on hold to sort out car issues. That’s why Robin Bradshaw of ECR Engines and Richard Childress Racing in Welcome, North Carolina switched the team’s pit-stop practice car to the Holley Sniper 2 EFI system. “In the past when we did practice pit stops, we actually had to fine tune carburetors day in and day out just to keep them where they could get out of the pit without stumbling or hesitation … now it’s easy just to roll into the pits, throttle up, and gas out.”
