OMGZ tall shifter

I want this badly, but $950USD is just too steep.

Anyone know the real name of this thing? It gives you a sequential tall shifter (think rally car) on an h-pattern tranny. NOICE. I love to google and find a DIY how to to build one for $40. So would you.

Are you kidding? Silly?? Unnecessary?!

Every rally car and touring car has this type of shifter.. you just bump it back upshift and forward to downshift. It's RIGHT beside your right hand, so you barely have to remove your hand from the wheel.

Seriously, I want to find a diagram of how this is engineered!!

check out http://auto.howstuffworks.com/sequential-gearbox1.htm for a description as to how it works

http://www.ikeya-f.co.jp/en/index.html is one company that makes them.

I'm sure it would be possible to design a simpler but less slick method of doing it.

edit this forum has a decent discussion about it http://forums.autosport.com/index.php?showtopic=87900

I want one.
It is not stupid and unessecary, That's like saying heel-toe down shifting is too much work!
It is genius and innovative among people who know how much of a pain in the ass it is to move your hand a foot to the shifter and back again every time you change gears.

Almost every full fledged race car has one.

i think it would be pretty annoying in a daily driver to not be able to skip into neutral anytime. it's also not a finger tap shift, it takes just as much effort if not more than a regular shifter (no hydraulics).

a subaru guy i know, with lots of money, bought one out of japan. tested it on the race car, never approved it. still races the H pattern. the advantage is marginal at best, and a big pain in the ass most likely.

im gonna be more than happy with my X5 shifter instead. it will bring up the knob closer to the wheel while keeping the shifts short.

Yeah, this kind of shift system is really only meant for track usage, but a system can be designed with neutral availability it will just have to be electronically controlled which makes it more expensive. However a proper system does take less effort and the shifting is faster because there is no lateral movement just forwards and backwards.



Is this that Subaru kit you were talking about? video is kinda corny but it looks like a decent system http://www.sssdrive.com/sss_eng.php

found a patent for a fully mechanically operated sequential shift conversion
http://www.pat2pdf.org/patents/pat6843149.pdf (edit: takes a bit of time to load)
for a 4spd tranny but could be adapted for 5/6spd with another cam. The select on the bmw transmissions is different though so the only part of that design that applies is the cam, and even the cam would need to generate motion in 2 axis.

I definitely want to design and build one of these for a 4th year engineering project if I can get it approved (buy an old getrag to prototype on, then retrofit to a car with the same transmission). I would definitely try to incorporate the ability to grab neutral at any time though.
