Double-Clutching vs Granny Shiftin

[blade34609]

Hi,

I was watching the Fast and Furious last night (the first one) and Vin Diesel was making fun of Paul walker about how he was granny shifting instead of double-clutching.
When I race I always granny shift will people make fun of you like they did in the movie cause u granny shift instead of double-clutch?
Also can you guys make it more clear to me what double-clutching is?
I have a good idea but im not sure.

Thanks

well i thought that ur synchromesh was so u didnt have to double clutch :S

Haha...that was a total BS line thrown in the movie for whatever effect. I bet they wish they could rescind that phrase and say something that makes sense after all the crap they've gotten for it

Double clutching is pushing in the clutch to take the car out of gear (say from 2nd to neutral), and then letting out the clutch while the tranny is in neutral, then pushing the clutch in again to shift into the next gear (say neutral to 3rd)

I do this always in my car because my 3rd gear synchros are screwed up and it helps it not grind so much...double-clutching is slow, but it is easier on the tranny parts...Granny shifting is regular every day clutch in, gas off, shift, clutch out, gas on, but it is slow for racing..most peeps 'speed shift' (i am sure there is more than one term) and never take their foot off the gas when racing, and just jam the gears around..hoping they get it in the next gear before they bounce off the rev-limiter too much - it isn't very friendly to your tranny tho

ok i am really sick of the misconceptions and myths that go around of what double clutching is and the benefits.

Double clutching is used when you shift from 3rd to 2nd or 4th to 3rd etc. say your cruising in 3rd and u see some guy fly past u and you drop it back, you usually get that first jolt of compression before you car takes off. If your in third and you clutch in then neautral clutch out then rev then clutch in and 2nd (providing you matched the revs approx right) then you get no compression and your car gets power straight away and you do not get the compression jolt that slows u down at all.

Just to get things straight!

This is also better on your tranny as it doesnt put nearly as much as stress on it.

I just laugh when i see people double clutching from first to second etc, it just slows you down.

Good lord! Do we have to make a sticky thread about double clutching?

[Rufes1]

hear hear

[XxLuckyLisaxX]

in my parts we call it...downshifting/rev matching.

i bet you got into the scene watching the flick too ...

we all started out somewhere i dont see how anyone has the right to make fun of anyone cause they saw some thing that made them get into the scene. hell im not gonna lie and say that f&f wasnt one of the things that made me get started in the scene. that and initial D cause it is the god of car anime. We all start with such limited amounts of information that we learn what we can where we can with so many questions the least you could do is not laugh and just tell him it was just a movie.

so with an attempt to not be rude, ...

Dude it was just a movie and just like everything in hollywood its an exageration of the real world. Like the better posts have said, its not really something you need to know about ... but something you will learn about with time and experience.

BTW Lisa, ive heard of downshifting and double clutching and i was told they were two diffrent things ...

I guess now would be the time to tell you that you're mostly wrong. Considering you say you don't like the misconceptions surrounding double clutching.

What you described is rev matching with double clutching thrown in. There is no need to double clutch in order to rev match for a downshift.

"Double clutching" is as sastanley described it in the third post in this thread. It has nothing to do with whether you are upshifting or downshifting. It has to do with not having synchros. In your transmission you have synchros so there is no need to do this.

Powershifting, or what he called "speed shifting", would be the proper racing technique for hard core dragging. Not double clutching. That is: Leave the gas pedal on the floor when you shift. I wouldn't recommend this to anyone who isn't prepared to pop a tranny though.

Hope this helps stop the misconceptions.

excuse me? I got into the scene by watching that movie? What kind of pathetic joke is that? I was around in the Toronto streetracing scene for ages. I was there when Mike Palijan was just a little street racer in woodbridge meeting up at Texas Pit making a name for himself before he became the fastest import in Canada...I was there when the A&E documentary people were chasing us around with cameras to make this movie: http://store.aetv.com/html/catalog/vp01.jhtml?id=17762 ... and I was there in Markham when researches FOR THE MOVIE FAST AND FURIOUS PART ONE were following us researching the Toronto street racing scene TO MAKE THE MOVIE. So don't gimme no bullshit about how I got into the scene by watching that gay ass movie.

I saw that documentry on tv, it was pretty cool
so how is the streetracing scene out there still? is it slowly quiteing down cuz of the cops?
i wanna come check it out for the hell of it one night

It hasn't 'slowed down' because there are still hundreds of people coming every weekend. However, the quality has died. There are too many cops and too many idiots so you don't really have too many great nights anymore. It's usually a few good runs and then cherries or spotlight from chopper. BUT, this is only if you frequent the well-known meeting spots (in woodbridge obviously). I haven't gone out to Markham yet this year so I'm not sure what's going on there. But there are alot of guys that do it secretly and you'll never find them. They don't want all the heat bags tagging along. I went with my buddy one time in his saleen. We were out racing all night with no cops in sight. So you pretty much need to know someone that knows where the secret shit is going down to have fun. There are some nights where the cops seem to have disappeared from woodbridge though.

that pretty cool man, i know of http://www.torontoracing.ca/ and they got some cool videos of late night street racing, dunno where the location is tho, but i know street racings huge in toronto. it doesnt seem so big in hamilton now, usually friday nights people gather at the beach to hang, and show there rides and chill, have burnout comps in the parking lot, my bro was there one night when like 40 cop cars came cuz there was one cop sittin behind a guy doin his burnout, when he finished and was pullin away the cop gave him a ticket and some kid thought he'd be smart and throw a fire cracker in the cops car, it blew off and 2 seconds later like every cop in hamilton was there. it was crazy, almost like the cops were sittin down the road waitin but i think since that, its died down here,
