Damn guys I've been trying to somehow figure out how this thing works and recreate it somehow but just got me mad that I couldnt figure it out
Anyways maybe some of you might figure it out but what I was thinking is maybe Soul Assassin could help us out and give us some prices on this unit here
I know I would buy one up quick..
Anyways heres a vid....you must right click and save as

Nice isnt it,,,,but come on someone find Soul so we can ask him on that thing, maybe even a manufacturers website.
And I think I have it figured out on how to go up shifting but dont know on how it would downshift.

It looks like a Seqential shift dogbox tranny.

Here's some from Quaife. I hope to get one of these for my kit car to mount my rotary to in the next couple of years. Mid-engine ~400 HP with one of these transaxles in a 1500 pound car. Rocket?

Here are some links that will hopefully work better

they make one here it is made by ikea sports. you can use it on your stock tranny, no dog box necessary! pretty sweet set up!

i can think of two ways to make a sequential shifter.

three actually... two of the ways convert a normal manual trans, the third one involves modifying an automatic trans so it uses a clutch that used to be somewhat of a cool idea, we called 'em "Clutch-flites" or "Clutch-glides" Then everyone figured out that the main advantage of an automatic WAS the torque converter so that kinda died out... it's still used to a degree in circletrack racing though.

Ever see a RapidFire bike shifter? The old one-lever style? OK now you know how the shifter works. How do you get it to work the gears though? My idea is you have a tube with grooves cut into it. Each shift fork (1/2, 3/4, and 5/R) has its own groove. Let's start from neutral... all three grooves are holding the shift forks in between gears, a fancy way of saying in neutral. you click the lever, which advances the tube. (Rotate it or slide it, either way you can make it work) The groove for 1/2 moves the fork into 1, and you're in 1st. Click the lever again... the groove clicks through neutral and into 2nd. Click the lever again... the groove clicks into neutral, and then the second groove (the one for 3/4) clicks into 3rd. So on and so on. Downshifting is just the opposite.

Personally I'd have it so the shift pattern is R-N-1-2-3-4-5, pull back to upshift, push forward to downshift. That's the way my T-bird was... I had a race shifter and a reverse manual valve body in the (automatic) trans, you start out in Park, pick up and pull back for Reverse, pull back and drop down for Neutral, then the ratchet worked for N-1-2-3. VERY sweet to drive, instant bang shifts, not like the tiptronic/autostick garbage that thinks about it for a second before shifting. OK anyway I'm rambling now...

It's a retrofit sequential shifter, and it's made by Ikeya (close Soul Assassin!).

It uses the concept of a motorcycle shifter mechanism (anyone that knows bike trannys would be familiar) taht uses a grooved sliding guide that selects (one of three) trigger plates.&nbsp Banging through the gears, it will alternately pul those trigger plates first forward and then back and then move over to the next plate.

It's been out for over a year, and we've looked into making them in the U.S., but we were worried it would eat up the stock synchros in the stock transmission prematurely.

I know a guy who uses this shifter in his FC down in Aussie who has run 10.9's, and he said it's a blast using that thing.

Just like some of the rally cars, that would be fun to have. Tiring I would imagine though.

so if you are in 5th, you'd have to bang that thing forward 6 times to hit neutral (in a r-n-1-2-3-4-5 setup)?

that would be a pain in the ***. I'm happy with my standard stick although I'd like a nice slotted chrome plate with a 6 speed

The real transmissions are over g-force

scathcart

a little off topic....

anyone know of a 6-speed rear drive transaxle capable of VERY high revs and very high torque levels?
I may use one for an interesting upcoming project.... Will be rotary powered.
I'm thinking Ferrari or Porsche, but if anyone makes an aftermarket, it would be great.

Did I mention I just received some money?

ooo, pretty. I never saw the video on takakaira. Looks like it would be slightly annoying unless it was an interiorless racecar. But thats what a sequential is for, right

Making the Porsche transaxle spin the correct way is a fairly common procedure for MR LT1 users (Fiero's, kit cars, et al) and for engine swaps among Porsches like a 914 or a Boxster. Aftermarket ones? Ummm....Quaife, C5 Corvette but I think this uses the drive shafts as a suspension piece, and checkout Racecar Engineering at the bookstore. They have a great vendor list in every issue!
