    RC, according to your sources, will there be another 6 cylinder 911? I hope so, an 8 seems stupid, they have more technology dont they? Direct injection n stuff? anyhow, I dont see why there cant be a 5.0 litre flat 6:))



    The reason there can't be a 5L Six cylinder engine is because when each cylinder is that big (833cc), the engine can't rev very high (huge reciprocating masses) nor does it make good specific power (power per unit of displacement). The optimal cylinder size for a normally aspirated sports car engine is about 350cc (This is why F1 participants went to V10 engines when the max capacity was 3.5L). A 5L Flat 6 would have a redline of 5,500 and have lousy performance for its displacement. The optimal engine design for a 5L displacement would be a V-12 if maximum power and sporty revving were the desired characteristics...

    Re: 997 S Technical Specs

    The top 5 F1 teams - Ferrari, Williams, McLaren, BAR, Toyota - spend north of $140 mln each annually for their engine budgets....(source: F1 Racing, April 2004)

    ...Pitch analysis on engine notes at one of the test tracks (Jerez?) indicated 20,000 rpm was being broached.

    So one has to pay, just a little, to realise the delightful F1 sonnet.

    Re: 997 S Technical Specs

    by active suspension, do you mean a system similar to early 90's F1? such a system would absolutely kill any competition from the lambo or 420.....

    regarding the f1 budgets, i believe i once heard that of all the companies, toyota currently has the most money to spend (makes sense, theyre the largest car company in the WORLD)

    No active suspension is truely active unless it can rebound actively.

    Something doesn't line up.

    It's like the first tests of the Ford GT. It turned some fantastic numbers, with Ford claiming it had "500" horsepower. It turns out the car had +550 hp.

    I don't think the 997 turned that lap time with the specificatiuons listed. Like Carlos said, it has less power than the gt3, a suspension that I can't believe is as good as the GT3, and it weighs more than a GT3?

    Come on now...

    5 HP less than the GT3 MKI, this isn't much difference since the first version of the GT3 was well known to have "under specs" engine power (around 345-350 HP were more accurate). The weight is a good argument but don't forget that the 997 S has a new generation suspension setup and the adjustable suspension could be another ace too.
    I think 7:56 for the 997 isn't exaggerated but I'm sure german SPORT AUTO magazine will do an extensive test on the Nordschleife. The GT3 MKII did the Nordschleife in 7:54 and I agree that 2 seconds faster than the 997 S isn't too impressive.
    But maybe there is something we shouldn't forget: over the past few months, it seems that most Porsche engines seem all to be more powerful than ever. I read a few 996 and 996 Turbo tests and the 0-125 mph acceleration times were usually 1-1.5 seconds better than in older tests. My Cayenne Turbo also seems to be more powerful than the first Cayenne Turbo I drove back in early 2003. So maybe some people are right if they say that Porsche HP should be multiplicated with the factor 1.1 lately.

    "So maybe some people are right if they say that Porsche HP should be multiplicated with the factor 1.1 lately."

    Yes, maybe only for cars delivered to magazines to do their test drives, they are using same technic AMG used with that incredible AMG 55 that made 0-200-300Kph better than the GT2. Than Rennteam made their own test comparo between a 996TT and AMG 55 and result was the one we all know, 996TT smoked the AMG 55, leave alone the GT2

    Last joke I saw from this magazine was a 996TT Cab that made 1,2Sec less to 200Kph than the 996TT

    I know it doesn't sound credible but over the past few months, I really got the impression Porsche cars have improved in "real" HP figures.
    But of course it is possible that Porsche does the same now what Mercedes started a while ago.

    I remember reading that article in the Portuguese magazine "Turbo"

    Anyway, for the 997S to match the GT3mk1 and only 2 secs off the 380HP Mk2, it would need to be running close to 400HP IMO since its even a bit heavier, and the suspensions on the 997S may be improved a lot but on a "S" model they are still intended more for street use and the GT3's are have less compromise and more track oriented. So no matter how good they are they can't work miracles with a more street suspension setup, huigh ride height, more weight, etc. So to match a GT3, Porsche's no-compromise track oriented absolute best handling 911, it would have to at least run 40HP higher than the Mk1, look at the 996TT it needs 420HP, sport suspension standard and tons of torque to achieve the same 7:56 time. I think that if that 7:56 is true, it must of been a "special" testing version.

    Re: 997 S Technical Specs

    We have already seen the 997 TT which comes normally out two years later. We saw also the 997 and the 997S.
    We also know that when the 996 came out in 1998 , less than two years later, they presented the GT3, but also the Turbo. So, since now we haven't seen any spy shots of the GT3 or GT2, in your opinion, is there going to be any GT model in the serie 997? or as some said they are waiting for the 998.

    And they've got to come from a long way behind, which means they have to try harder just to catch up with the leaders.

    Re: 997 S Technical Specs

    Is it real time adaptive suspension like enzo has or is it simply a 3 setup suspension like soft hard and track or something similar, cose thats nothing new citroen had it in its Shark models in the 80

    I'm sure that Porsche's PASM is the same as the Citroen system in the 80s.
