I know what powershifting is. I am not familiar with what is meant by 'no lift foot to the floor' powershifting. I guess he could have meant that you don't lift the gas pedal foot, and you slam the clutch pedal to the floor, but that is not what is said. It left me wondering.
Yeah gas pedal to the floor, engine almost on the rev limiter, quick small stab on the clutch,as the engine gets into the limiter. Clutch only stabbed part way, just enough so the gears can slow down when the sliders are engaged.This keeps the air ripping into the engine, and with a 7000 rpm shift the Rs fall to .73 or to 5100, so the engine is practically unaware that a shift has actually occurred. On a streeter, the tires don't even have time to stop spinning.
This can also be done with the street slick-shift modification, which has the benefit of zero concentration required around town, just drive it like normal, cuz all the brass are still in there.
