Crikey this reviewer didn't like the Selespeed, I think he was being a bit harsh though, and wonder was he fully familiar with the optimal launch mechanism for the Selespeed?
I have seen a number of articles that mention a selespeed full gearchange process time, for sport mode in 0.7 seconds.
i.e. from button press back to full torque application.
Vs 1.5seconds for normal mode (less thna 60% throttle).
I have driven a 2.0L T-Spark selespeed and liked it, I really didn't think its upchanges were VERY quick to be honest.
The whole experience was quite pleasant though.
Sure it probably is quicker than most people would do when driving in a relaxed fashion, and having two hands on the wheel in the twisties will mean a lot, also it is definitely much easier to be in the right gear.
If you are snaking sideways under braking on the track sometimes it is hard to do a smooth heel and toe
I think the GTA selespeeds do quicker changes though?
BTW does anvbody have references to technical data concerning the gear change time for more modern Selepeeds which indicates the time for the return to resumption of full torque.
I had seen it previously but can't find it now.
BTW There is a lot of slightly disingenuous Alfa "marketing speak" where they talk about the time taken to "initiate the gearchange process" instead of the whole process, so you have to look at the information critically.
I did try and time some of my manual GTA gearchanges on the track,
I have very accurate timing gear, and I could see the time taken for
clutch application, gearchange, gradual torque resumption as the clutch comes out, and reacceleration back up to the speed that you lost while the clutch was in.
My figures with MAXimum effort to change as quickly as possible - which required real concentration and pysical effort!
..were 0.3 seconds for the full gearchange,
this broke down roughly as follows
0.1s to get out of gear, .1s to engage gear and leave clutch out, .1s second for full torque resumption.
It also takes about .1s to accelerate back up to the speed lost during the "quick" change!
I wouldn't be able to change at this speed all the time, and doubt if it would be good for the life of the gearbox.
Probably I would be generally doing it .2s slower on the track normally unless I was overtaking somebody.
BTW the selespeed downchanges are lovely though, but generally gear changing speed is not that important for downchanges .

It does the change differently depending on how you drive. I can only assume that either you did it wrong, or the selespeed you used was broken.
And selespeed owners want to reveal the correct technique?
And I never said that he 'wouldn't know how to change gear'. In a pressure situation it's very easy to make a mistake, even if it's as small as a half second delay in getting the power down again. If Senna can get it wrong occasionally (and he did) I'm sure HGT man can.
