POWER SHIFTING
Does power shifting (double clutching) actually improve your speed? ---> if you know what you are doing of course... because people say that it does improve you 1/4 mile (gives you an extra "BOOST" between gears) but if you watch racing videos (actually track races) where the cameras are in the cockpit, the pros don't seem to do it... or is it different for track racing then drag?

Re: POWER SHIFTING
Power shifting in a drag race is when you shift gears without lifting your foot off the gas.<P>Not good if you use nitrous.<BR> <BR>If you miss a shift your engine will hit the rev limiter.

Re: POWER SHIFTING
double clutching is used to match revs when down shifting...power shifting..just slam the gears as hard as possible....I'd just clutch and shift as fast as you can

Re: POWER SHIFTING
no no no, double clutching is what they do on semis and big trucks, clutch in to pull it out of gear, and push the clutch in again to put it back in another gear. you dont do this on cars unless your synchros are fucked. and matching your rev speed when downshifting is called "heel and toe downshifting".

Re: POWER SHIFTING
i know that stevech_2001 but you said matching revs when you "downshift", thats called heel and toe downshifting. anyways, you dont double clutch in a sports car, it doesnt happen, the fast and furious movie only said that just cuz it sounded cool, sure the movie was cool, but it was far fetched enuf with civics crawling under semis, at least they could've kept the dialogue real.
Re: POWER SHIFTING
"you don't double clutch in a sports car"..<P>heheh you should have tried driving my old, POS 1973 MGB.. old brit cars have poor synchromesh at the best of time so double clutching was very necessary, up-shifting or down-shifting, spirited or normal driving.<P>"spirited" being a relative term in an MGB ![Smile :)](./images/smilies/icon_smile.gif)

Re: POWER SHIFTING
When slowing down, I always double clutch. You push in the clutch, shift to neutral, let the clutch out, tap the gas, push the clutch, and go into the next lowest gear. This will bring the speed of the engine close to the speed of the transmission therefore reducing wear and tear on the clutch, because it does not slip as much. If it is done properly, it will be a very smooth downshift. BTW - it also sounds cool.
