Rev Matching
#3
it's the term used for shifting while clutch is engaged.. 3rd to second would consist of pulling out of 3rd, revving 1k or so rpm greater and throw it in second.. pretty pointless, it comes in handy while accelerating though, or rolling stop signs

Its used in non syncro transmissions. In most modern transmissions, we have syncros which allow gears of unmatched speeds to engage smoothly. In non syncro transmissions, the engine speed must be matched to the speed of the particular gear you wish to engage or the gears will simply grind. (Some larger desiel engines still uses these transmissions).
The only real advantage this has on modern syncro transmissions other than less drive shock, and glass smooth shifts, is control. On a wet road, a downshift without raising the rpms can break the tires loose by underspeeding them which can be enough to start a slide.

It also comes in handy when clutch cylinders and/or throwout bearings have failed and you are away from home.

Obviously the clutch has to be in (disengaged) for you to be able to rev the motor...
Gently blipping the throttle to rev match is easier on the transmission overall. Definetly makes things smoother - just don't rev the crap out of the engine (you shouldn't be revving over 3500rpm on a regular basis anyway).
I do a similar thing with my automatic - if I decide to manually downshift the auto, I always making sure to press lightly on the gas while doing so. It does it so much smoother and with less strain on the car.

1. you need a flywheel
2. you don't really stop in neutral, you're just passing through![Smilie](https://maxima.org/forums/images/smilies/smile.gif)
It's generally
1. clutch in
2. shift and blip or blip and shift
3. clutch out
< .5 seconds

Forget that... the good old power shift from 2nd to 3rd.
Who needs to feather gas when you can keep it planted.
Last time I did that, I burned the tires for a good 50 feet, and drifted into oncoming traffic.

Oops... I probably redline everyday and rev match between 4,000 to 5,500 a lot...
