Holley to Supply EFI Throttle Bodies to NASCAR Teams in Transition to Fuel Injection

Holley has a long standing relationship with NASCAR helping assure high quality fuel delivery products have been supplied to their teams for over 40 years. Holley Carburetors have powered every professional NASCAR team since the 1960s.

“Holley is proud to have powered the amazing machines found in NASCAR for over four decades. We’ve successfully delivered the fuel for 28 million miles in NASCAR cup series racing alone, not including NASCAR Nationwide, Camping World Truck, and other NASCAR series we work with. We have spent nearly two years engineering our new throttle body for NASCAR and are confident we will continue to get the job done as they make the change to fuel injection,” said Holley CEO, Tom Tomlinson.

Holley will manufacture the new throttle bodies in their ISO 9001:2008 certified Bowling Green, KY facility – the same facility where the majority of their NASCAR Carburetors have been manufactured. The throttle body is a critical component in the electronic fuel Injection system and will be the key to regulating the airflow to the NASCAR racing engines. The Holley throttle bodies were designed using computational fluid dynamics (CFD) software to assure the airflow met NASCAR specs.

The new Holley throttle bodies are constructed of aerospace quality billet aluminum and will be machined on five-axis CNC machines to hold the demanding tolerances required in NASCAR racing. They feature 17-4 stainless steel throttle shafts, throttle levers and linkage to handle the extreme conditions found in NASCAR racing.

The throttle shafts and throttle plates are profiled for maximum airflow. The throttle shafts will ride on sealed needle bearings for smooth operation and durability. The venturii have been contoured for efficient yet maximum airflow. A positive throttle stop has been built in as an added safety feature. Each throttle body will be anodized for corrosion protection and then individually serialized for NASCAR.

“The fuel Injection side of our business is a critical path to our future. We have a lot of excitement around our new fuel Injection program and the NASCAR throttle body will help us continue on that path. NASCAR teams demand the best and we intend to keep delivering just that,” said Tomlinson.
