Interesting thoughts but no correct guesses:biggrin: I have 2 two steps. The first one you hear is on the foot brake and it helps build some of the launch boost (I can build about 8 lbs on the foot brake). Then the 2nd two step is on the trans brake and the rest of the boost comes in much quicker. I launch at about 21 lbs. So it seems like I sit on the 2 step forever but, in reality, it's not that long. Besides, this was only a time shot and I was shooting for a record so I wanted to make sure that I build 100% of the boost.
