I heard the same rumor. Cant remember the exact details though. Ford had a few major issues with its GT when it was released, American supercar quality seems to be lacking...lol

Yeah. The new porsches will have 450 hp and weigh 300 lbs more than the Z06. The "myth" about euro supercars is getting harder to keep up...There is not one euro supercar that has the driveability or durability of the ls7. The reason they do not do track days is cause the euro cars break when you beat on them and then no one knows how to fix them. Go racing and find out the truth as opposed to reading bullshit in car mags.

FYI...

(There are no lash caps on the exhaust valves)

Why they would put a lash cap and a non steel tipped titanium valve on a motor like this I have no idea (supply issues?)

He said in the other thread that it is lash caps on the valves, since it is using TI valves the cap had to be put on for strength

big freaking secret

clearly you haven't witnessed a "track day" over here in the UK then!!!!

you find that the dominant cars are noramly:

Lotus seven replicas (ie westfield and caterhams to name just two)
lotus Elies
Scoodies and Evos
and the Porsches!

now, track days over here normal mean racing around a track as fast as you can, or your car will let you! Porsches have a great reputation for taking huge abuse from people atending these days and still being used monday morning to drive to work! they are strong and very reliable! im not saying the corvette isn't any of the above. all im sayinf is there are a lot of people giving their Porsche a really hard time on the road and the track and the cars just keep going!!!

now i cant coment on drag racing!

thanks Chris.

Interesting.

I know it was widely published in Porscheofile magazines that the Carrera motors have a bad tendency to "blow up" under repeated abuse with as little as 30K miles on the odometer

Being in the UK, I'd imagine you would have read about this already.

The factory Turbo motors don't seem to suffer the same malady. These reports that I read were on the previous Generation N/A motors eg. '01, '02 etc.

they had some isses with the water cooled motor intermedaite shaft bearings ( lol @ had still do). Some early ones dropping liners. The turbos dont have that problem since they still use the 964 case.
for the most part their bullet proof, we have only see one where the bottom end came apart, they really hold up pretty well, even when beaten hard.
