This is the same as double clutching?
What the fuck is Rev matching
I'm not a fan of risking blowing my engine in my daily commute
>>14152572
When you're at a stoplight, you rev the engine to where you want to end up in traffic flow (let's say 3000rpm, for example), then dumb the clutch at the same time as flooring it.
It makes the clutch plate engage a lot faster and thus prevents wear.
>>14152583
That sounds incredibly risky
>there are people on o who don't park there car in gear in case their handbrake fails
>>14152526
No. Rev-matching is used in modern transmissions with synchromesh gears, to alleviate some of the stress placed on said synchros.
Double clutching is what you do to match input shaft and output shaft speeds, when you do not have a synchromesh transmission. Anyone who double clutches in a car with synchros is clinically retarded and should be beaten to death with a severed nigger penis.
>>14152583
sounds like a good idea i will be sure to try this in my personal vehicle

Wrong. There is literally nothing wrong with double clutching in a car with synchros
>>14153089
I don't know what any of this means
>there are actually people on this board who drive manual every day and still don't know that putting the car into reverse while traveling at speed is the most efficient form of engine braking
>they actually think it will damage their transmission
>2016
>this stupid fucking wives tale is still preventing people from engine braking properly
Do you honestly think an automaker would design a transmission, with everything we know about people's driving habits, that is capable of breaking from one tiny shift? It engages the reverse gear only partially if you're traveling at speed, and slows down way smoother and faster than the lower gears. Plus you don't get that jolt you would from lower gears.
>>14153111
There is literally nothing wrong with washing your hands before dinner, then washing them a second time despite not having done anything to make them dirty.
This is double clutching. This is stupidity at its finest. Synchros were introduced specifically to eliminate the need for double clutching. How are there so many stupid teenagers on this board, holy shit.

That's OK, 98% of /o/ doesn't know how a manual transmission works, let alone what a synchromesh gearbox is. There are even retards here who drive stick and think they need to double clutch. Probably because they're cuck manlets too afraid of the noise their engine makes when they rev-match, or because they're too useless to figure out how to blip the throttle properly.
>>14153131
Probably sue you and win when the brake fails and the car rolls down the hill and kills/injures someone.
Not to mention the criminal negligence charge you'd incur, and the niggerdicks/AIDS you'd be welcoming into your anus.

Are there seriously people here that drive manual and cant rev-match? This has to be a joke...
>not having syncros
>2015 + 1
>>14153133
Okay, so
The gears both have to be spinning at a matching speed so they mesh correctly, right? If they're not at a matching speed, they'll "grind" together (where the phrase "grinding my gears" or etc comes from).
In older cars, this was done by double clutching so you could sync the engine with the tranny
In newer cars, they have synchronisers, which basically create friction on on of the gears to slow it down to the correct speed.
Might be a bit wrong, it's been a while since I was explained all this
>>14153156
Rev-match if you're driving a car made after 1960.
Just blip the throttle before downshifting, it reduces the torsional stress placed on the synchromesh gears. These synchros are designed to help match the rotational speed of the output shaft (the shaft leaving the tranny, going to the wheels), with the rotational speed of the input shaft (the shaft transmitting power from the engine). If the two are drastically different, trying to link them will put a lot of stress on everything in the tranny. Not good. So by rev-matching you bring the rotational speeds closer together, and the synchros pick up the slack.
You can downshift without rev-matching at all, but it simply wears the synchros more. They are designed to wear, and are not a finite piece of equipment, but they should last the life of the transmission if you shift properly. People who burn out synchros are probably swaggot boiracers who redline every fucking gear and dump the clutch every shift.
Don't double clutch, it's a stupid waste of time and completely irrelevant. There is literally no good reason to do it other than to be an edge fedorite shitlord faggot.
Rev-match:
1.) Traveling in 4th gear, want to go to third.
2.) Push clutch in.
3.) Move shifter to 3rd.
4.) While moving shifter to 3rd, blip throttle with your foot (a little tap) that brings it to around 3,000RPM.
5.) Let clutch out swiftly.
This eliminates the giant leap your tachometer will make if you didn't rev-match. The difference is that the tach jumped because of a controlled tap of the throttle to match shaft speeds, instead of the slamming together of two drastically different shaft speeds.
Note: you may have to fiddle with the precise amount of throttle blip, it varies from car to car. Basically, the smoother the downshift (no jerking or bucking of the car), the better. Fine tune and learn that muscle memory.
>>14153173
You are correct, you understand fully what is happening inside of the transmission. It's important to understand that gears are made up of ratios, you aren't just selecting ONE GIANT GEAR WHEEL for 3rd gear or whatever. You have constant motion from all of the gears when the vehicle is moving, but only one set of gears (or ratio) is linked with the output shaft. This is why it's called a transmission, because it transmits power selectively to the wheels.
Well done anon. You know more than most of the shitheel faggots here.
>>14153209
Do people seriously not know about ratios
>>14153193
should have read "are a finite piece of equipment"
>>14153218
People here think it's better to double clutch than to rev-match, so I don't assume they know anything. Least of all about ratios.
>>14153127
I always thought people with synchromesh transmissions double clutched because it's supposed to be easier on the clutch than granny shifting.
>>14153257
If you're shifting to the appropriate gear, and you're not dumping the clutch, anything else is really a moot point. Those are the biggest concerns for clutch wear. Aside from actually riding the clutch (keeping it only partially released, so it grinds on the flywheel), there isn't much else to do in order to maintain clutch integrity.
Double clutching is what dipshits do to feel special, it's a horrendously stupid meme you'll find in the deepest cesspits of "car culture". Except these faggots actually double clutch, because they have no idea how a manual transmission actually functions.
If you ever meet someone and they try to convince you that double clutching is a good thing on a modern vehicle, cut their throat immediately. The police will understand.

I can probably double clutch faster than most of you can shift normally.
>>14153696
Ok then, tell me how rev-matching with the clutch pedal depressed does anything to save the synchros. The way I see it, when you press the clutch, the input shaft of the transmission isn't spun by the engine as you blip the throttle, only the throwout bearing. But I'm willing to learn.

>>14154442
>>14154659
is this nigga serious?
I always heel toe double clutch rev match my downshifts. double clutching is very important when doing downshift from 6th - 3rd or 4th - 2nd for instance. if you don't double clutch it puts a lot of stress and wear on the synchros. when you double clutch when you don't look like the gear shift snicks into gear like butter with no effort at all. if you only rev match on downshifts like that you might grind the synchros because the speed difference between the input and output shafts is huge
basically you're all a bunch of faggots that don't know shit. fuck off and die. thanks.
>>14154741
You're still autistic for double clutching in a car with syncromesh.
It's useless nowadays and makes almost no difference to the syncro's life span.
They're designed to take some abuse... Shifting like a retard is what kills your syncro fast.
>>14154828
I probably am but it sounds really awesome when I do it and my 3rd gear synchro is almost fucked so I do it to save what's left of it

>>14154852
possibly. the forks are a known weakspot. it only grinds if I try and go from 2nd to 3rd to quickly. I ha e to give it an extra half second on upshifts to avoid grinding.

ive missed 3rd racing a few times a long time ago which probably didn't help much

>>14153842
this guy is right. When the clutch is disengaged and the car is in neutral, the input shaft of the transmission is essentially free wheeling. Selecting a gear at this point uses the synchros to bring the input shaft up to speed so the gear you're downshifting to can engage. rev-matching at this point only reduces clutch wear as the engine is spinning at the same speed as the input shaft when you take your foot off the clutch. If you don't rev match, the engine is spinning slower than the input shaft, so the car jerks as it speeds down and the engine speeds up. If regular rev matching didn't put any wear on synchronizers, then this would imply the synchros are not being used. If you could bypass use of the synchros by rev matching, then it would allow you to downshift a non-synchronized transmission, which it doesn't. You have to double clutch to bypass the synchros.
That said, double clutching is pretty pointless unless your synchros are already completely fucked or you're jumping gears. Going from 5-2 is going to rip up that 2nd gear synchro because of the difference in speed of the input and drive shafts. In normal shifting, the wear on the synchros is minimal. The input shaft is a small part and has very little rotational inertia, relative to, say, the engine or drive shaft, so spinning it up requires very little force and therefore puts very little stress on the synchronizers when you're going from 1000 rpm to 2500 rpm.
Okay there's a shitload of misinformation in this thread.
Rev-matching: bringing revs up while downshifting to downshift smoothly and not fuck your synchros
Double clutching: clutch in, neutral, clutch out, clutch in, gear, clutch out. This is unnecessary if you're not driving a truck from the 60s with synchros you fedoras
Heel-toeing: a method of rev-matching, not rev-matching itself.
>>14157612
I can't tell if this is just a meme now or what. Did you try to read the post above yours? Rev matching is identical to a non-rev matched downshift up until you re-engage the clutch. Why would it affect the synchros any differently?

Well..there are people who think driving manual is some kind of achievement so I guess rev-matching feels like a super advanced racing technique to them.
After all, it's not like kids, soccer moms and grampas all over the world have been driving manual their whole life, it's totally something to be proud of
Looks like a thread full of loud arrogant children who haven't experienced a transmission that requires double declutching.
Perhaps your syncros have worn down. Perhaps, like two of my three manual transmissions there aren't any syncro gears to help you. Perhaps you have damaged a clutch finger or plate and declutching is the only way to move between gears.
There are many scenarios that require you to select neutral before selecting a gear. Plenty of mechanical issues that may leave the transmission in a state that needs declutching to shift around the box. Why is this something to fight about?

this guy proves my point. if you need to do a 5th to 2nd downshift, like when cruising and wanting engine braking for a steep hill, and don't double clutch, you'll fuck your synchros very quickly because of the huge speed differential of the input and output shafts. synchros are like mini clutches and will wear out.
fuck off. thanks.
