Hi all,
I have ssen a few cars around with the quick shift electric hydro system which with a push of a botton changes gears for you. I wondered if anyone had moreinformation about these systems? How much they cost and how they work? Is possible to build one or use a paddle shift system with cables?
Thanks again Alain

I'm not quite sure of what you mean by electric/hydro, but one quick shift is Kliktronic which IIRC is about £600, and is used by forumla 27 (or was, don't know since they've been bought by YKC).

My eventually plan for my locost is to put a bike engine in it, with kliktronics to change gears, techtronics to blip the throttle on gear change and a rev limiter to feed the kliktronics, result - no need to change gear, just stamp on the throttle, and it'll take it to the limit before quickly changing gear, right the way up. Shouldn't be desperately heavy either.

That is what I am lookig for I am using a zx9 engine and am trying to find different ways of using those parts. Ho much do you think your system would cost? What happens to the clutch?

Or have a look here!

Translogic

Translogic looks very nice, but it's still rather more expensive than the kliktronic/tectronic/limiter combination, and they don't seem to aim at kit cars at all, not that it should really matter, I can't imagine it's too had to remove the buttons from the handle bar mount and stick them on your steering wheel.

Looks a bit more professional too.

The former sounds cheaper so I've sent them an email. Has any one actually used them? What happens when down shifting /clutch operation.
Alain

The kliktronic is quite heavy and basic, but does the job. I wouldn't use one again though. I prefer paddles and cables which are much simpler to install, and weigh less too.

How does the paddle system work ? Can you buy one off the shelf or do you need to make one.
Alain

You basically have to make the system yourself, and it's very easy to do. I've made some that attach directly to my steering "wheel". My steering (off-road) is very direct (7/8 turn, lock to lock!), so your hands never leave the "quarter-to-three" position, and the paddles are always just at the fingertips.
I have also made set-ups for conventional round wheels/rack ratios, using a ring, slightly smaller than the diameter of the steering wheel and mounted a pivot on the steering column (you could also mount it on the steering wheel boss too).
The paddles hinge on the pivot, and operate the cables, while the pivot also secures the cable sheaths.
Two cables are used, and both pull, so light weight cables made up by your local bicycle shop will suffice.
The cables can run parallel as far as the proximity of the gear lever on the bike motor, where they will need to be separated by approximately 75mm, and the outer sheaths secured to a bracket.
The inner cables are attached (to a modified shift lever...just cut the splined boss off, and weld it in the centre of a bit of 19x5 flat bar), either side of the splined shifter shaft. The distance from shaft centre to cable nipple holes will need to mirror the leverage of the paddles (unless you want a specific advantage)
As of tomorrow, I'll be away for a few weeks, but if you want to email me and remind me, when I get back, I will send you a sketch, if all the above isn't clear.

that sounds great. Where abouts are you I would like to see the work if possible.
