What is power shifting?

LMAO...ok here is an experament for you...go get a car with a newer transmission....get going in 1st, then with out pushing the cluth in try and yank it out of gear into neural....isnt going to happen.... power shifting is not letting off the gas between gears, a good way to screw the tranny and engine along wiht in lower gear get rid of that anoying tread...double clutching is how you have to shift in older, or non syncro trannies....you basicly push the clutch in, take it out of gear (neutral) let revs drop if shifting up, bring them up if shifting down, then push the clutch in and go into gear....power shifting is actually a great way to induce oversteer in a corner (drifting) and so is engine braking... oh and for thoes of you who dont know what engine braking is it when you are in say 5th, then you want to slow down so you push the clutch in, let the revs drop in neutral, then shift into a lower gear (ie 3rd or 4th) and then slowly let out the clutch....dont drop the clutch because your wheels will not completely lock up but will get very close and you engine revs will jump from idle to redline or higher in a matter of seconds...not good any anything mechanical on your car....

sorry...but you are quite wrong.... syncro's where invented along ways before most muscel cars came about.... in order to drive a non syncro classic vehicle you would have to go back pre 1960 or drive a truck....

ok i think u guys are a little confused. double clutching is used for upshifting. now all our hondas are indeed synchroed which means the gears automatically synchronize before you put it in gear. now my friend happened to burn a synchro. not fun. ur tranny will make a little grind just before you put it in gear. so now on to double clutching. double clutching is used quite a bit in drag cars. usually only in cars with straight cut gears. ever seen a gear outta ur tranny. the cuts run on an angle. now straight cut gears are used to get better lock. they dont ever slip. but with straight cut gears there are no synchros. in order to get the car in gear properly you have to make sure the tranny is running at close to the same speed. thats why you let up the clutch in neutral (gets ur motor spinning with ur tranny). so in a car with straight cut gears you first push ur clutch pedal, shift to neutral, release clutch pedal, again push the clutch pedal, shift to ur desired gear, then release. now good racers can do this in a matter of milliseconds. thats right under a second. it begins to feel natural, just flows in one fluid motion.

Double clutching was a thing of the past, like in the old old days when manuals didn't have synchros and had to double clutch so that their gears wouldn't grind, but some people double clutch anyways just to bring their rpm up after shifting. Power shifting is simply keeping it floored while you shift instead of letting go of the gas like your supposed to.
