Another thread prompted me to put this idea forward. Please not this isn't really a 'drifting' technique. Atleast I don't think it is.
I've been trying to work out if there's any advantage to actually double clutching on the upshift. I have heard from alot of people that this is completely useless in cars with synchros- but apparently it's actually used amongst some drivers and it's supposed to enable you to get better acceleration.
This is my theory:
When you're making the shift to neutral - you can pretty much bring the clutch straight up - because the only thing the engine is fighting is the weight of the layshaft and gears, compared to the entire weight of the car like you would experience under a normal shift in normal driving conditions.
This is one split second shift.
So assuming that shifting to neutral can be done as fast as possible without damaging anything, and the fact is that now that the lay-shaft is spinning at the right speed, you should be able to put it into gear and dump the clutch without any jolt or causing any extra wear.
This is a second split second shift.
So when you think about it - double clutching the up shift means that yes - you hit the clutch twice - but by doing that, you're enabling yourself to bring up the clutch much faster than you would normally. So you're actually reducing the lag between putting the car into gear and making the power connection from the engine to the wheels.
You're basically replacing one long shift with two split second shifts.
I mean yeah sure - you can always just change gears and dump your clutch - but that creates that JOLT effect which creates a lag on your engine.
In effect you end up keeping your revs up around wear you'd want them more effectively, and therefore accelerating faster.
Whaddya think?
Guh... I haven't had a good nights sleep in a few days and it's currently 1:02 AM.
I swear driving needs to be a job. I'm studying Commerce and I spend too much time playing Initial D, watching Initial D, looking for a new car and looking at my finance options, when I could be studying, or sleeping so I can study better.
I've just got a new job and most my money will be going towards the car - I don't think I'll have text-books next semester. I'll probably sell my old ones to help save for my car too the way I'm going. LOL.
I'll probably read this when I wake up and think: "WTF?!"
Anyone wanna point out any holes in my theory?
