NHRA officials announced today that hood scoops will\u00a0return to Pro Stock bodies beginning in the 2027 season, along with removing the single\u00a0forward-facing throttle body and replacing it with two top-mounted 4-barrel style throttlebodies. This comes from the NHRA Technical Department\u2019s continued effort to add\u00a0more parity, continue to increase participation and reduce overall long-term costs for\u00a0teams.<\/p>\n
This announcement comes a decade after the Pro Stock category transitioned from two\u00a0carburetors and hood scoops to electronic fuel injection (EFI) and flat hoods in 2016.\u00a0EFI will remain for 2027, but hood scoops will return to the popular category, which has\u00a0seen strong participation in recent seasons. After extensive discussion with teams,\u00a0racers, engine builders and crew chiefs, the strong majority were in favor of adding a\u00a0hood scoop air entry back to Pro Stock cars, starting next season.<\/p>\n
By adding the hood scoop back, along with the new dual throttle body EFI setup, the\u00a0consensus is that it will provide a more beneficial and efficient way to tune the cars, with\u00a0less variation from car to car.<\/p>\n
\u201cThe general feeling among competitors and stakeholders is the current low\/front air-entry setup makes the engines more difficult to tune and creates more variation from car\u00a0to car than it should,\u201d NHRA Director of Engineering Clinton Snead said. \u201cBy adding the\u00a0hood scoop and top-mounted\/dual throttle bodies, it should eliminate those issues,\u00a0which should help all teams, but especially the smaller and lower-budget teams.<\/p>\n
\u201cWe\u2019re excited about the return of hood scoops and the addition of dual throttle bodies\u00a0in Pro Stock. There was considerable momentum from teams, racers and engine\u00a0builders to make this move, and we believe this should draw added interest from fans\u00a0as well, returning to more of the classic look fans have associated with the category.<\/p>\n
\u201cThe class is in a strong place as far as overall participation, and we\u2019re confident this\u00a0move will only continue to add to the depth and interest in Pro Stock.\u201d<\/p>\n
Along with the strong visual element of hood scoops, the addition was made with an eye on increased E.T. performance.<\/p>\n
Hood scoops will only be required to meet a limited number of measurement rules, similar to previous guidelines. The 2027 rules package for Pro Stock will also include loosened rules on throttle bodies, manifolds and air inlets.<\/p>\n
The new top-mounted dual throttle body rules will be based on dimensional requirements, allowing teams to build their own units or work with outside companies. The manifold rules will also be opened up to allow for increased innovation and performance.<\/p>\n
