Smooth transition from higher gear to a lower gear. Man it feels nice. Not really helpful on up shift since engine slows when you come out of gear and by the time you get to the next one the clutch and stuff are at about the same speed anyway, right? I had been wondering and wondering what the heck double clutching is. Since I CAN'T DO A SEARCH HERE I found some site that explained it for people whose clutches were slipping bad. So this actually saves a clutch, right? Nothing to tear it up, right?

 

Double clutching saves the synchros since the job of double clutching is to bring them to the correct speed before performing the shift. This practice isn't needed for everyday driving since the synchros are designed for it. However, if I was dropping multiple gears, I would probably double clutch as that daves the synchro from the beating it would otherwise take. As for clutch wear, you don't need to double clutch to save it, just rev match on down shifts.

 

Yeah.. its not necessicary when upshifting. Why is this in the 6th gen forum btw?

 

someone let me in on the secret... im an idiot ... how do you doyuble clutch?

 

 

maximadriver.com has some howto's on it

 

What if you just down-shift but let off the clutch real slow. You still get a smooth downshift. Any drawbacks to this method?

 

Only drawback I can think of is the 'riding the clutch' effect, which reduces clutch life. Rev-matching allows you to release the clutch fast and still get a smooth shift. Good for when your racing on a course, etc. Double clutching on the upshift helps when the clutch life is low, or your synchros are bad. I used to drive really old buses and trucks with NO synchros where double clutching was a neccesity!

 

People actually still double clutch?

What is this 1950? lol

 

I thought double-clutching was if you didnt have synchro's (Older Ferrari's)

 

All's I know is that double clutching gives me instant acceleration on a downshift like when I passing on the interstate. No jerk or anything. Now I guess I should say though that the pressure plate on my clutch is getting old, says the Nissan guy anyway. Clutch is hard to press down. Harder than when I got the car the first of 01. I could push it down with my pinky then almost. So maybe double clutching feels so great to me because I will need a clutch in a while.

OH yeah, I mistakenly put this post in here. I was so excited and all, you know. Plus I had just read a new post on the sixth gen and I probably just hit the "post a new thread in this forum" button rather than going back to the fifth gen forum. So, excusez-moi. Je suis desole.

 

thats the worst possible way to downshift.
the drawback is that your clutch is taking a tremendous amount of wear slipping though the shift and at high rpms.

another drawback is it takes a long time to actually make the shift.

you don't need to double clutch, but you do need to rev-match.

 

Okay what do you mean by "rev match"? I believe that could actually be what I'm doing. The term "double clutching" and these latest posts lead me to believe that with this process there is a pressing of the clutch pedal two times during a downshift. What I actually have been doing is just clutch, neutral, gas, down shift, release clutch. Is this actually "rev matching"? What is the real difference between rev matching and double clutching? Is double clutching actually pressing the clutch, moving to neutral, releasing the clutch, hitting the gas, pressing the clutch again, shifting to the lower gear, and releasing the clutch again? Why would someone need to do that? That just takes too long. Or is it a skill with practice thing?

 

Yes you are rev-matching, and the latter you described is double-clutching (pressing the clutch twice during a rev-match shift). It was mainly needed for old trucks, buses, cars...that had NO synchros where it was almost impossible to get into the next (lower or higher) gear without double clutching... It also helps when your clutch is bad but its not necessory as newer vehicles have synchros...

I also 'heard' you should not skip a gear (you dont have to release the clutch in every gear during a down shift, but you should still go through the 'motion' with the shifter as it helps keep the synchros in tact... or something along those lines)

 

Just a simple question...do you guys double clutch during city driving, like say, I was going 40 and I wanted to make a right turn at the light and the light was green. Just wondering...


also, I hate it when I over/under-throttle sometimes...there are just some days when I'm off.
