Otter, I have the utmost respect for you... you always have awesome input . But this made me giggle, and maybe its just me... but 4th-5th isnt really supposed to be a quick shift. 5th is for cruising only..... but the more I think about it, the more I think maybe you are just being funny .

I am the same though for heel-toe. I need to work on it more too.

 

Does is it really helps doing double clutching. All I know it's for big trucks.

 

Because big trucks don't have synchros. I think the main reason is because most big trucks are 8 or more speeds. Synchros do what double clutching used to do, so I don't see HOW double clutching is quicker. Like someone else said, jam that shifter into the next gear, the synchros will take care of it. Driving like this all the time however, is not good. Similar to driving an auto at WOT all the time. Shifting at 6000rpm ALL the time isn't the best thing for the transmission. Isn't going to make it fail sooner, but it will put some extra wear on the clutches/bands.

 

Who said anything about shifting at 6000 rpm? Sounds about 750 too short to me

 

 

The automatic, in drive, shifts at about 6100. The only way to go over that is to shift manually.

 

Once you have quick shifting mastered, go drive in Australia, England, Japan or South-Africa and do it with your left hand.

 

Had a Japanese fella who drove slalom for fun take me for a ride in an Escort I once owned. Scared the **** out of me! Going into turns he would slam the clutch to the floor and reach with his left hand for the shifter. We'd be free wheeling into turns with the guy trying to open the drivers door!

 

i double clutch when i raced the rsx type-s, pulled half a car on him when i did it.

 

Somebody please explain to me how it is physically possible for double-clutching in a synchro'd car to make you faster

 

i used to double clutch whenever i'd race...it made little to no difference...now i just stick with single clutching/quick shifts. i find it better to just stick with that...

 

What I can't grasp is: why would you double-clutch while you were upshifting??? Wouldn't that just make your shift time that much longer and increase your times?

 

double-clutching while upshifting is no longer needed or helpful when upshifting, it can only slow you down! double-clutching while downshifting is used all the time on the track(road course) to match drivetrain and engine speed. If your lazy you can accomplish the same thing with single clutching on down shift, Double clutching is easier on the tranny.

 

Is double-clutching even useful in any way shape or form on downshifting in a car with synchro? Rev-matching, yeah, good. Double-clutching, why, why?! I get the theory, not the practice.

 

thats what i am wondering also
