First, the restrictor plate openings will be slightly larger (1/64th of an inch). This will yield from 7-10 more horsepower. I'm not sure how this translates to miles per hour or fuel mileage but I'm sure the former will go up and the latter will go down. How much of an effect this has remains to be seen, but it became obvious that the cars and driver skills were capable of safely running at increased speed as two car tandem racing speeds were up to 10 MPH greater than were single car qualifying speeds. I'm thinking the two car tango was actually much more dangerous than normal single car racing just based on the fact that the driver in the push car couldn't see what was happening up front. I know they tried to have radio communication between the two drivers hooked up, and it helped, but we all know how fast bad things can happen and we witnessed some accidents that normally wouldn't have happened.
Second, and the change most likely to break up the drafting, the cooling system's pop-off valve will be set to release water vapor at a lower temperature than before. In other words, the car doing the pushing won't be able to maintain a long-term draft like before. We've seen the two car hook-ups last as much as ten laps (in cool weather) before the trailing car had to get fresh air through it's radiator. The new valve will go off at 8 pounds per square inch less pressure than the old one and according to David Reutimann's crew chief Rodney Childers that change will drop the tandem run's durations down to 1 lap at the most.
A crew chief's nightmare?
We all know the drivers aren't going to give up a procedure that gives them more speed and because of this the rule changes will result in more pusher / pushee switching which, in terms of safety, may not be such a good thing either.
