The National Hot Rod Association (NHRA) has announced its approval of Racepak’s SmartWire, a lightweight power distributor that “eliminated fuses and relays” for use in the Pro Modified category.
Although Pro Modified cars don’t have the speed of Top Fuel or Funny Cars, they have has become one of the most popular divisions of professional drag racing. The NHRA generally races Pro Mods on 1/4 mile tracks, resulting in high 5 to low 6 second passes, while the American Drag Racing League (ADRL) runs their races strictly on 1/8 mile track setups, allowing for high 3 second-to low 4 second passes.
SmartWire is already used in Competition Eliminator, Super Stock, Stock, Super Comp, Super Gas, Super Street, Top Dragster, Top Sportsman and E.T. Brackets.
“The use of SmartWire and the technology it provides will allow racers and chassis builders a more simplified wiring option, as well as a faster and more technically advanced way of switching electronic devices, which can in turn provide benefits in both competitiveness and safety to the vehicle,” explained Racepak's pro system and sales manager Todd Paton. He also acknowledged that the company “provides contingency awards to racers in the categories it is approved for with the exception of E.T. Brackets.
