When or does anyone know if someone out there is developing a sequintial gearbox for the transaxle cars?

Seen it on a 105 and it is  fantastic! Get some quick shifts from that;-)

I don't believe it will be done. Plus the money involved

You could put in a troublesome Albins transaxle like what the Car of the future teams are currently enduring, at only $27,000 a pop new, you could also wait untill the teams start flogging them off thru the back door, for a bargain, a good sequential gearbox should stop you selecting the wrong gear, but if you break a gear or engagment is difficult you can't not select it like you can with a 'H' pattern, Colin.

Its a pity money stops a lot of dreams:-(
But yes colin that probably would be the way to go! Do u know if any other cars that have a sequential box which might be 'adaptable' on the transaxle cars?

Imagine a gtv6 with a 24valve engine and with a paddleshift sequential gearbox ;D

If you break an Albins with your Alfetta, I want to see that car!

Seriously, keep an eye out on ebay and Auto Action, for race car parts, as the V-8 teams 'life' a part of say X amount of racing klms, then the part becomes old and unreliable, so its sold out the back door at the end of the year, there are a few old Holinger gearboxes doing the rounds in sports sedans and club cars, Colin.

A far better sequintial transaxle than the current Car of the Future boat anchor they are currently using would be a Getrag 6 speed transaxle that is used in the current Porsche Cup throughout the world, they are all converted to a straight pull back to go up and push forward to go down sequintial Hollinger dog box, they occasionally come up for sale, think of it as a long term investment or 'heirloom', not a consumable that costs you money every time you use it, Colin.

I have seen old Holingers out of Group A Touring Cars, the H pattern 5 speeds for $12,000, in Auto Action, the Porsche Cup Transaxles would be upwards of that, now that last years V-8 Supercars are Obsolete in the main series, they have plummeted in value, Colin.

You can't use a Porsche transaxle in a (RWD) transaxle Alfa. The Alfa TA has the diff behind the g'box and Porsche TA has the diff in front of the g'box. Silly, incidental things like the rear suspension get in the way of making it work.................  ::)

Hey Duk, it would be a job that would go on forever!, it would be best if you could convert the existing Alfa Transaxle to a dog change from a synchro change for lightning quick gear changes, i am sure someone in the world has done one, after all, look at the transaxles that raced in the 70's and 80's, Colin.

Col, there are at least a couple of dog ring, straight cut gear sets available and a bloke on the AlfaBB posted a few pictures of his attempts at converting a TA to sequential shift, but he was talking about basing it on a standard synchromesh gear set, which would be boarder line pointless...............  :o
In my mind, Alfa TA's really don't have the mechanical strength or enough gears, to justify the effort and expense.

colcol

I agree Duk, for a sequintial gearchange to work properly, it has to have dog teeth on the gears, not synchro teeth and cones as they are too weak to transfer power and the synchros are too slow to engage, and straight thru up and down motor cycle type gear change would wreck the synchros in no time, Colin.

Something I watched recently http://www.youtube.com/watch?v=1QJlL0zNdMA (watch all of the videos on the Agera R!!!)and the first thought was that the same principle could be applied to the sh!tty syncros in the Alfa TA.
It's not ever going to happen (kinda, a little bit difficult to apply to an existing g'box :o ), but the pure genius of the idea (though, in my understanding of how the system would work, it would be more like a wet brake than a wet clutch.......) was very inspirational.

Granted it's not an MX5 or a slick rally Escort but hey, that's a bit over the top...
