How practical is sequential shifters on the street. Of course, the primary reason would be mile runs and RR.

 

you mean shifter or gearbox?

if shifter you mean there is no one working properly, my tuner is working together with bosch motorsport and tests will start this winter, this will be pedal shifter.

 

I see them in LG Motorsport (GM) cars but nothing in a Porsche.

 

GMG and Oakley design made/make them. GMG had one in a 997 turbo a few years ago.

 

Thank You ....I looked at GMG and nothing.........I will look up Oakley.

Update: They (Oakley sequential shifting) is in development and I have asked them to provide details.

 

GMG definitely made a 911Turbo with a sequential shifter (based on the manual gearbox already in the car). Give them a call as I believe it was a one off car they made for SEMA a couple of years ago and the car has since changed hands a couple of times and last I heard was back to manaul.

 

it's not working....I think it was developed by tag heuer..

 

Isn't there a sponsor on here sequential shifter?

 

By searching "sequential shifter" / " SQS Cartronic" from 997 & 996 turbo forums all answers are found...including the important one; "Is Oakley Design worth working with"...

And the link to that shifter: http://www.sequentialshifters.com/

 

It seems sequential is making them for Oakley. I also found an article that Guards is also developing a sequential. Nothing on their website but I may do some research.

 

Karol,probably he speaks for shifter..i know also the same ...no onw working well...if he means gearbox..we speak for huge cost....RUF has in CTR3......

 

Yep! RSS put one in a GT3RS.

 

They look reputable. I found a link in the forum where Guards indicated that the use of these sometimes will increase the wear on synchros and dog teeth.. I am not sure if it is from extreme use such as professional racing or all out throttle runs many times.

Some statements from Guards...............

I just want to mention that the increased wear on the synchros and the dog teeth with this modification is very real. We've had several customers need to rebuild their gearbox in less than 2 years of installing this shifter. Performance has a price and you always need to be willing to pay to play...

Another from April of 2011.....................

Yes. We don't rebuild boxes in house, but have a network of authorized installers all over the country. In addition to our LSDs, we offer gears, forks, bearing plates, side covers, etc. etc. When the time comes, we can send you to one of our dealers for service. You can look at a list of them on our website. We only work with the best of the best in the business.

And for the real serious track junkie our true sequential conversion will be to market in less than six months. We just finished the design work and have it all in Solidworks now. We'll be prototyping it over the next few months and sending it off to a super secret testing partner to work out the bugs. It's going to allow the conversion of a synchronized street box to full sequential function for about what it costs the Cup Car guys to service their factory sequential gearbox.

I never said that it will damage a differential. That's ridiculous. I said it can accelerate the rate of wear on synchros, which are a gear related service item.

As for the release of the full sequential gearbox conversion, it's been delayed a bit by a completely unexpected recovery in the market. We've been scrambling to cut gears and manufacture differentials from our existing line of products because there's been so much demand this Summer. The conversion kit is still out there on the drawing board, and has in fact been programmed into the mills and gear cutting machines. The big challenge right now is getting a break in our production schedule to push through a prototype kit that we can send off to one of our strategic partners in racing for some discrete testing this Fall. Don't expect anything before Christmas, and realistically a full production version won't be out until next Spring.

Matt:

I must have misread/misunderstood ( see attached link on my previous post). I have read the link and yes indeed I read it incorrectly, I apologize. I sent an e-mail to your Yahoo acct but looks as though you have answered my question below.

Thanks,
