Of course, the transition from gasoline engines to power plants with electronic fuel injection in the Pro Stock class has become the main topic for discussion at the beginning of the season as the fans in the community and among the people directly involved in the competitive process.
Opinions were divided: some fans very positively about the changes, because «the court is not the eighteenth century,» while many pilots believe that injection engines — is certain death for the division. Another innovation in the regulation was the fact that now the teams participating personnel strictly forbidden to close the engines during operation in the paddock. Ostensibly it is to spur interest in the race among the public, as well as increase the awareness of all those who want to know about the technical features of cars a little more than the ordinary man in the street, which emotions from burned tires and the roar mnogolitrovyh engines is more than enough to spend money on tickets and paid translation.
As the first step in Pomona, this requirement has been successfully ignored completely in each box. Engines of all dregster were carefully covered with towels. However, as journalists Hot Rod Magazine noted, mechanics, though reluctantly, but lifts the veil of mystery on demand. The radical «no» correspondent heard only in the paddock team Vincent Nobila.
In the days of the former air regulation from the air got into the engines through the huge air intakes on the hood, but now it happens through the two slots in the place where there is a bumper cars at the factory. Naturally, the temperature at the surface of hot asphalt significantly higher than over the hood of the car, and it directly affects the amount of oxygen entering the combustion chamber. And, according to most experts, this difference is «eats» about 50–80 horsepower at peak load conditions. And to somehow reduce losses in power mechanics obkladyvayut entire intake tract layers of ice and covered them with towels to dregster went to the start with maximum cooling inlet. In terms of the letter of the law — it is a direct violation, but from the standpoint of common sense — commands use all available means to somehow adapt to new realities. In NHRA Winternationals technical inspectors have closed their eyes, but whether such indulgences take place in the future — the big question.
