Flick then release the accellerator, then shift. The same way my driver's education instructor and driver's training instructor taught me. I asked a bunch of guys about this at the last SCCA event, and everyone of them laughed and told me not to watch the fast and the furious. The whole reason for revmatching and doubleclutching was to mesh up the straight cut gears. Vehicles are designed now so that you don't have to do this... but if you want to, damn the engineers who built them, go for it. :thumbup:
So are you holding the clutch in when you downshift? Or are you shifting without the use of the clutch at all? I still don't understand how you could downshift using that method you described. I would also like to know how you could downshift rapidly from say 5th to 3rd?
I don't know who you talked to at the last SCCA event but if this conversation is going to continue lets get on the same page too:
Rev matching = hitting the gas to bring the RPM's to a certain level- usually to match the speed you are going with a gear you are down shifting into.
Double clutching = downshifting by putting the clutch in, selecting neutral, letting clutch out, REV MATCHING, putting clutch in, selecting gear, letting clutch out.
I'm kinda confused when you say rev matching and double clutching seperately because double clutching incorporates rev matching.
One last thing I was wondering, helical cut gears still use sycnros as far as I know. Dog gears/ straight cut gears generally do not.
