I don't think it will. Seems like there would be a big loss in efficiency. You're burning off power slipping the clutch. And I don't think the energy stored rotating the crankshaft assembly will be anything near the energy that otherwise would have been transmitted to the wheels.

I'm sure depending on where you are in the country everything is called something different. I wasn't sure exactly what you were referring to so I listed both shifting methods.
they are different. However either or will slow your cars forward progress. I could get more technical on my answer but it involves complex math

Just make sure you bring a tow truck to pick you and your transmission up you leave behind on the track.

Didn't read more than the first few replies...

It's called "clutch kicking" and its a technique used in drifting for low horsepower cars. Completely useless in a straight line.

why would he need a tow truck to pick up pieces of his transmission? this isnt any rougher on the car then shifting gears hard and its very doubtful that doing this just a handful of times would burn the clutch enough to leave him stranded. you would have to pull the e-brake and sit and slip the clutch for several minutes to do that much damage.

Ya I see, i mean hear.. honda's and acura's do this all the time at the drags. It wont do anything to make you faster. All your doing is stopping the car from accellerating and the boost or kick of power you feel is just the car starting to accelerate again. Only time this helps you is if your rear wheel drive going into a turn, pop the clutch, tug the e brake and DRIFT that sh!t. It is pointless on a drag race!

double clutching is when you have to shift from 1st to neutral to second to neutral to third and so on in old old cars with unsyncronized clutches. i've also heard truckers have to do it sometimes uphill but they may not be true. Also a good method to use if your clutch is completely gone to make it to the garage. i think the powershifting confusion came from f&f, but that conversation has been had way too many times.

ya, clutch-kicking would be an interesting thing to try though. i guess if your car was so underpowered or heavy that the energy gain of letting it free-rev for that second and going the next second was greater than letting the car rev in gear for two seconds this would make sense. possible i suppose.
