2010 turbo

Road and Track mentions that in this month's issue, concerning the GT/3. It supposedly improves drivability lots.

 

Just a small detail here but the new 2010 Turbo lost it's famous GT1 motor. The good news for some is the new DFI 3.8 motor is compatible with PDK for the first time in a Turbo. However the PDK may limit max to 500HP. PDK might not like HP mods either like a better sounding exhaust system.
It seems Porsche does listen sometimes; with new paddles behind a much more attractive steering wheel for PDK cars. Never one to admit when they are wrong the old style rocker shifter steering wheel is still available to...
The new Turbo II standard Turbo 5 lug wheels are an even bigger visual failure than the previous Turbo wheels were. For those that want their Turbo with PDK then 2010 is their year.

Tested is an understatement, it was used by Porsche since the 80s in severe racing, 962/956.

"7-Speed Dual Clutch Transmission by Porsche and ZF Enters Volume Production"

* Faster gearshifts without traction interruption.
* Lower consumption with improved driving performance.
* Presentation at the 'Transmissions in Vehicles' Event of the VDI (Association of German Engineers) in Friedrichshafen.
* Volume production launch in the Porsche 911 Carrera.


The new dual clutch transmission is presented for the first time to approximately 900 engineers and press representatives at the VDI 'Transmissions in Vehicles' Event in Friedrichshafen. The 7DT sports transmission is particularly suited for applications with high engine speed requirements. Gear changes without traction interruption allow for very good acceleration and vehicle handling with low fuel consumption. The transmission was developed in Kressbronn, Brandenburg, and Schweinfurt; it is produced at the Brandenburg site of ZF's Car Driveline Technology division.

Drivers of sporty cars expect their vehicle's engine power to be transformed as directly as possible into dynamic propulsion. In addition to this acceleration "linked directly to the accelerator", however, they also attach great importance to automatic shifting comfort. ZF's 7-speed sports transmission accommodates both requirements for vehicles featuring highly powerful engines: the sporty agility of a manual transmission and the shifting comfort of an automatic transmission.

In the dual clutch transmission this becomes possible by connecting two separate transmissions to the engine via two parallel powershift clutches. The even gears are located on one transmission, the uneven ones on the other. This basic principle of the transmission has the advantage that one gear in one of these transmissions ensures propulsion, whereas in the other transmission the next gear is already preselected by the electrohydraulic control unit. When shifting, one clutch is closed while the other opens. During the shifting process, traction is not interrupted. This means that, during acceleration, engine torque is continuously transformed and propels the vehicle - making an essential difference from the manual transmissions which were usually installed in powerful sports cars. In contrast to torque converters, the dual-clutch module by ZF Sachs, the Powertrain and Suspension Components division of ZF, is also suited for higher speeds of up to 8,000 revolutions.

All gear changes - also downshifts - are processed just as evenly and quickly with the 7DT 50 (that is the ZF-internal product designation); so the ZF dual clutch transmission sets a new benchmark for sportiness. A new speed governing concept, which is used for the first time in volume production with the 7DT, also contributes to these extremely short shifting times.

The drivers can choose from fully automatic shifting or manual gear selection via shift paddles or a shift lever. Also in the fully automatic mode, ZF offers several shifting programs: Apart from the comfort mode, there is also a sports and a supersports mode, the latter with considerably increased shifting dynamics (fastest shifting times and race-start function).

The 7DT sports transmission by Porsche and ZF excels thanks to its high power-to-weight ratio: The gears and shafts of the dual clutch transmission, which weighs approximately 120 kg, are produced from case hardened steel according to special, ZF-specific delivery instructions. ZF-engineers have introduced several measures - for example, controlling the cooling fluid flow as required to keep drag losses low. The 7-speed dual clutch transmission not only allows for particularly sporty driving performance but, thanks to its very good efficiency, also achieves consumption values which are below those of a manual transmission.

Especially with sports cars, there is a demand for transaxle transmissions - that is, transmissions with an integrated differential and axle drive - the 7DT sports transmission can also be supplied in this variant, which is suited for mid-engined vehicles with rear axle or all-wheel drive. This transaxle version of ZF's 7-speed dual clutch transmission is starting volume production in the torque range up to 450 Newton meters.


>>> New reference with dual clutch transmissions: The 7DT sports transmission by Porsche and ZF is available in two versions, for torques up to 450 and up to 700 Newton meters. <<<

Just checked the Porsche website.

The standard wheel for the Turbo is fugly.

The optional RS wheel is smokin' hot !!!

 

+1. basalt black with the RS wheels, plz!

 

The TSW Hockenheim clones?

pretty sure the Turbo is using BBS wheels, of which the TSW's are clones.

 

I'll be keeping my 997.1 Turbo, the GT1 engine really is a gem and easily tuneable. I recently had a re-map to 550BHP/600LBFT for £2K . I have been reliably informed that the GT1 derived engine can easily and reliably take 700BHP.

With regard to the 997.1 Turbo wheels, I never really liked the style of the wheels in pictures etc. but when you see them in the flesh, on a Meteor Grey car, they are stunning. I wouldn't now consider changing them for something else. I also feel the same way about the 997.2 stock Turbo wheels, I hope they look nicer close up.

If the 3.8 engine in the 997.2 Turbo is not as highly regarded as the GT1 engine, it can only be a good thing for generation 1 owners .

 

Sounds like quite the rocket ship you have built with 550BHP now. How do you like the feel of the PCCB system? Always nice when you can drop 40 pounds of dead weight. Also unlike on your manual car; the tiptronic transmission option adds 66 pounds to the end of the car that hardly needs more weight. Though the tiptronic was popular with the better half has your wife tried rowing though the Porsche gears yet. The Turbo clutch is much more pleasant than the GT3 clutch. Roundabouts must be fun in the rain!

My wife loves rowing with my stick, she says it feels really nice in her hand! It could be because it has the short-shifter option though!

The PCCB brakes are really nice too, none of the on/off feel you got on the earlier setups.

 

Rowing, eh?

I almost keeled over when I saw this.

Maybe you need a fast transomation to a better vehicle!

 

Glad to hear your TT is in good hands!

TT does that represent Tiny Toy?

 

You can always rely on GC!

I have to hand it to you, Martin!
