My point is that we are already shifting 2/10th of a second... and at a 1/4 envery 1/10th counts... or for 60 to 130 as well... where some of us shift .3 to .4 seconds... will this unit do it faster....

 

errrr..... what MARIUS said.

though..... the sequential box made by Porsche runs around $25K for the refurbished unit. get one @ http://www.cantrellmotorsports.com since he runs a 997 Cup team and would have access to some good boxes. It's just a natural question that if it were really this easy to do a transmission with a sequential vs the factory Porsche transmission then Porsche would have just put an actuator system on their standard box. For people who worry about shifting from 5th to 2nd all of the time, this product certainly removes that possibility. That is probably worth $10K to "more than a few" people, from what I have heard.

 

I know race teams that have removed the race sequential, as it is so expensive to replace. And depending on who drives, yes it needs replacement a lot.

The Oakley Design GT3 had 60.000 km on the odo when I last saw it over here in Sweden. Most of it on track! 5 magazines test drove the car and Jon Oakley was on track for almost all day, full attack, unless when he had to stop for drinks and petrol. There were no issues with the car. He drove from the UK and back, except for the ferry then The car certainly has some race patina!

The feedback in the press was very positive. One journalist had a 997C2S and he said it would be his nr addition to the car if the modified it.

There are so far 2 Ruf R Turbos (650 package) with this shifter in Sweden, but more to come. I think Marius is getting one as well

I don't have any other measurements other than 100 - 200 km/h in 5.6 secs (Driftbox), pre-Oakley shifter. Veyron does it in 4.9.





I hope MARSKI and more will try this.

 

Look the Volvo's on FIRE!

 

I'm sure the Oakly Unit is fine... And in a GT3 as a "test" of endurance means nothing to us TT owners...

We don't have the cooling/heat exchanger the GT3 has, and we're penalized with a substantial weight disadvantage over the GT3. My points here are this:

It may well survive under the power of a lightweight, lower torque platform. Will it survive in one of our beasts?

As Tom Kerr found out in having a custom oil cooler installed on his tranny, the temps on the oil in the 996TT gearbox go above 300 degrees... THIS should be your primary concern if you're tracking your car for multiple days back to back as some of us do.

I think you need to check what the Oakley Shifter does, and what it includes.

 

From their website:

"The only physical change to the car is to remove the shift unit in the car and replace with the taller sequential shifter. Remove the two OE cables and replace with one cable supplied. The unit then bolts to the side of the Porsche gearbox. No welding, bending or permanent modification is required. The system is electromagnetic. It receives a signal from the shifter in the car. The driver pulls back for first, again for 2nd, again for the 3rd, 4th, 5th and 6th. Reverse is one push forward of neutral.
When shifting from 2nd to 3rd the shifter does the sideways movement on the box in addition to the fore or aft movement and the same from 4th to 5th (effectively across the gate).
Use of the clutch is required as the system still uses the OE gears.
The result is shifting is about twice as fast as OE. It removes room for error especially when track driving i.e 5th to 2nd which is often catastrophic to engines and transmission.
In addition shifts are much easier mid-corner especially when pulling larger G forces. With this system it is just a quick ‘******’ of the gear and keep accelerating.
It makes much more sense when driving it….!!!
This system is ‘fit and forget’ ie. it needs no maintenance. Also the car can be reversed back to OE H pattern if and when required."

And my main concern still stands... regardless of the "type" of shifting, if you don't have the proper COOLING for the gear oil, you're facing an expensive rebuild.

Maybe some want to "look cool" with a sequential setup. I want to sort out the shortcomings of the internals/externals before I spend $8K on a "shifter".

It is a shifter, it is not going to have any effect on how hard the transmission works.
It is a mechanism for changing gears. Weight of car, has no bearing on the efficacy
of this unit. It seems very cool, but it also very expensive.

If you have a problem with cooling already, this shifter won't help, and they never claimed it would.

But I can't see how it would add to the problem if you don't have a cooling problem?

It takes a bit more space, but nothing that would add to the heat AFAIU.

 

Maybe I didn't explain myself well...

My point was that before you start thinking about spending tons on a cool shifter, you might want to address other known issues...All 996TTs that are being tracked should consider a tranny cooler for the fluid. They don't come with them from the factory like the GT2/3 do.

And Woodster I'll have to disagree with you on the above comments... Trans components are directly impacted by torque and weight. The mass being moved acts as a force multiplier as it increases. The internals on a transmission will be impacted by many factors.

Mike

 

I will receive mine today/tomorrow

 

Sounds pretty interesting, i remember when it first came on this forum, i was considering it depending on price (when i had my TTX50) but for 10k... i wouldn't have been considering it anymore...

mmmmm.....aaaahhhhh....Thats What She Said


sorry guys i couldnt resist

 

So isn't this system essentially the same at maybe half the cost?
