f1 did have boost buttons when the had turbos, and have them a little boost in the straight to help with the over taking, but it was very hard on the engine
Modern f1 cars, i think (they are hiding it or not talking about it) have a button that will allow the engine to rev past the red line, the new engines don't rev as high as they did b4 because of the 1 engine per weekend rule, but they might have a button on the new cars that will for a second allow the cars to rev higher. (200revs = 4bhp i think)
