Nearing the season 2016, which will mark the beginning of the entry into force of new regulations in the class NHRA Pro Stock. We have been told that from now on all engines necessarily receive electronic fuel injection instead of a pair of four-barrel carburetor, the hoods of cars to lose huge air intakes, have become in recent decades the hallmark of class and will cut the length of Willie bars that, according to bosses NHRA, should increase the entertainment races.
We want to share some of the details that pop up now and then in the press about topical technical features and appearance dregster, which will replace the usual devices. The title picture with the image of the new Dodge Dart current champion in the class Erica Enders Stephens, will speak about appearance of cars that will compete in the coming year, better than any words, and the outline of the body is to be expected began to resemble the technique class Pro Mod, equipped with a turbocharged engine capacity of more than eight liters.
With regard to external changes: in connection with the transition to distributed injection of fuel and a decrease in the maximum permissible engine speed from 12 000 to 10 500 rev / min, the height of the intake manifold has declined, and the air from the atmosphere into the engine now gets from the front of the dregster through a long duct rather than directly through the impressive air intake mounted on the hood. If we talk about the technical part, the experts teams inevitably faced with a lot of new challenges, starting with the fact that instead of spanners when setting engine is now coming notebooks, ending with the fact that a completely new configuration of the engines will inevitably entail the need to change almost all of the friction characteristics and transmission.
Thus, the control unit of the fuel system, the design of the nozzles and the throttle will be identical for all participating teams.
Only admitted to the competition by the manufacturer of fuel injection system is a firm Holley, earlier also supplying carbs exclusively for Pro Stock engine. The tight schedule for implementation of new technology NHRA in close cooperation with specialists from Holley in every way possible support teams in the off-season: conducted numerous seminars and senior technology consultant sports department Holley Robin Lawrence personally attended the workshop participants of the championship in the event of any problems and questions.
At the moment, to make any predictions regarding the dynamic and high-speed characteristics of the new cars is very difficult. Despite the fact that preparations for the new season is in full swing, the final finishing technology in the context of the new rules in any case, will be held during the championship.
