I'm hearing you both...
Years ago I used to race a 5 speed LX Torana in Darwin, I would reasonably consistently run 11.8 at 114 mph, (even won a few meetings). I used to launch it pretty tamely though, and lots of guys would come up and say, "you need to rev it more and dump the clutch", but I also had to drive it home which many of those guys didn't have to worry about... I found a technique that worked and just went with it. To get the shifts right, I had a big shift light that was right in front of my face and as soon as I saw it flash, I'd shift.
Funny thing is, I used to think that I was changing gears lightning fast, that is until I saw the video..... It almost looked like I was driving to Coles to get the groceries
