OMG - GT3 Preview at Silverstone this Wednesday. Get to meet God - Andreas Preuninger

[Adam2S]

Ive found a youtube video of the UK launch day! Not much to see but the colour on the video is pretty much how it looks in real life.

Yup, that be Guards Red. Good find

Wheres MIA Buttons123 ?......, we wait with baited breath

He however pointed out that the alternative method of disconnecting the vaccum hose was extreemly bad for the engine as it damaged the integrity of the vaccum system which was used for other critical functions.

Where is this vacuum hose located?

I just did a google, and found this: Are these the hoses what Andreas were referring to?

Yes I believe that is it... That looks like a GT3 pic to me - its the same connector but in a slightly different place on a normal Carrera/S

Been playing, try this if it works will post the rest.

Looks a bit too thick to me!

WOW

In terms of the dual mass/single mass flywheel there are a number of factors that need to be taken into account:

Weight
As the single mass is lighter this will alter the dynamics of the car. *This affects other components such as the suspension set-up and is therefore not as simple as just replacing the dual-mass with a single-mass flywheel.

EMU
The Engine Management Unit (computer that controls things such as fuel injection cycles in the engine) has been set-up specifically for the dual-mass flywheel. *Therefore it knows exactly how fast the dual-mass flywheel will spin under any amount of load. *The single-mass obviously has very different behaviour so there would need to be re-programming of the EMU to cope with this (and I
don't believe our colleagues in Weissach would ever release the EMU programming for the single-mass). *Fitting a single-mass flywheel without re-programming the EMU could cause major problems -
hence the invalidation of the warranty.

Vibrations/noise
The dual-mass flywheel produces a lot less vibrations/noise which is why it is fitted to the GT3. *The single mass would compromise the on-road dynamics of the car.

Positioning of the car
The GT3 is positioned as a road car that can be used on the track. *So we have to take into account some of the comfort elements (vibrations/noise) to make sure that we please as many customers as possible. *The GT3 RS is a racecar that can be used on the road
which is why we feature much more racing componentry such as the single-mass flywheel.

Hopefully the above makes sense. *It is always a very tricky subject as some GT3 customers always want to make their GT3 more 'extreme', however, this is really why we have the RS model.

I hope the above makes sense.

So that's a pretty comprehensive answer to a couple of avid track gents. Buy a RS rather than mess about with the " normal " GT3 set up.

It took a while. But we got there!!

Great detail! Thanks for following up and posting everything.

It's too bad Porsche is taking such a hard line on modifying the standard GT3. Adding lighter exhaust and flywheel to achieve better dynamics shouldn't be such a big issue. IMHO, rather than casting clients adrift who wanted to upgrade their cars, Porsche should offer the upgrades through dealers and stand behind the warranty. Yes it would cost more than buying aftermarket, but at least you'd have the choice to maintain the warranty.

Sounds like it's RS or nothing for me (despite being an American).

Thanks - it all makes sense now. You're a star.

I *thought* that there was a sensor/input to the ECU/DME that indicated which flywheel was installed on the car to enable the ECU to adapt ...

failing that you could always install an RS DME in the car ... maybe someone @
Sharkwerks can comment ...

Ti exhaust appears a given based on comments from the event and classic Ti discoloration on this spy photo. In addition to the likely 25-30lb weight saving, the exhaust will also mean different EMU programming.

If I were Porsche I'd offer a simple upgrade package for standard GT3 that included single-mass flywheel, Ti Exhaust, and RS chip. I suspect there'd be a lot of takers.

Not going to happen..

Want the upgrades?, follow the marque and buy the RS in the first place

So, it's still a muffler, not a bypass? I wonder where the extra 14 horsepower is going to come from?

Anyway, I don't think the entire exhaust system will be made of Ti, it will be just the rear muffler (like the GT2).
