Turbo Face-Lift Caught On Test

Unlike steel brakes the coefficient of friction of the carbon ceramic brakes actually increases as they get hot so F1 drivers actually have to back off brake pedal pressure as they brake to prevent locking up. So the hotter they are the better they work (to a limit of course, they can catch fire if they get too hot). Also because ceramic doesn't conduct heat, the heat is not transferred to the fluid, therefore no brake fade.
Shame they cost £5k really.
BEST option by a mile from the factory - well worth the cost (compare with how much ceramics cost on Ferraris!)
The reason they are glowing is that the Turbo is trying to keep up with a GT-R on the track []

So is the 3.8ltr engine the first turbo not to be based on the 'GT1' style block? If so it will be interesting to follow its reliability.......
997.2 Turbo = 500ps/660Nm in new DFI 3.6L engine
Yes, no more GT1 Metzger engine []
The least I was hoping for was a development of the GT2 engine into the Turbo. ie an X50 kit plus a bit more.
Porsche must be looking to invest in futures again next year rather than car development. (Was is 3.2b from investments and only1b from car manufacturing??)

and changing to a cheaper base engine that still has reliabilty issues.
Crickey, you can at least wait a bit until there is some evidence to back this claim up. How many of the new Gen 2 engines have suffered the same problems as the previous engine? How many have suffered any problems at all? It's off the cuff comments like this that gave the previous unit a worse rep than it deserved - the stats show it was ultimately a very reliable engine.

I wouldn't consider RMS to be a reliability issue in terms of overall engine reliability in that it's not an issue that will leave you broken down on the side of the road. It is an annoyance and unfortunately has cost people money, and it is a shame Porsche hasn't stepped upto the plate in dealing with the issue, but it is not a reliability issue - The engine works perfectly fine, it just leaks a bit of oil as all previous models of Porsche have done in the past and have been accepted as being just a quirk of Porsches. Also I know of about 20 people who have Boxsters/Caymans and 996's at work and when i've asked them if they've had any oil leak problems not one of them has suffered so much as a drop of oil on their drive. Not a large and statistically significant population I grant you, but if RMS was such an eppidemic as some would have us believe, then i'd have though i'd have thought that at least one of those people would have suffered.
It just 'feels' to me that the problem that Porshce related forums like to highlight don't feel to be as widespread when you look at other non-Porsche specific forums and publications who generally still regard Porsches as being bullet-proof.
