    This is fantastic indeed because this piece of "paper" is the FULL product info, you can't get anything better without paying for it.
    But hurry up getting it, we may be asked to remove it (hopefully not ).

    Re: Product Info and Training Doc

    wow...this is great information. Thank you Ron.

    Re: Product Info and Training Doc

    In a word, WOW!

    Re: Product Info and Training Doc

    how do you decompress a php? sorry for total newb question

    Re: Product Info and Training Doc

    This is huge.....A great work of art.....better get it before its gone. I like the competion comparison section at the end.

    Re: Product Info and Training Doc

    I wonder why they left the Z06 out as the core competition?

    Because it's considered to be the core competition against the GT3

    Re: Product Info and Training Doc

    Thank you for posting that piece..the information was great.

    Re: Product Info and Training Doc

    That's an incredibly informative read!

    Brian,
    Any chance you have access to the info doc on the C4S?
    Thanks ahead of time,
    Matt

    Re: Product Info and Training Doc

    Excellent read!
    Thanks for sharing!

    Re: Product Info and Training Doc


    Re: Product Info and Training Doc

    ahhahaha excellent information! thanksss .
    sorry but i readed many times.. the pressure control tires is standard for all world right? it means that my car will have it?!!?

    Re: Product Info and Training Doc

    Thanks Ron!!

    Re: Product Info and Training Doc

    Wow, thanks Ron. I'll keep this doc forever.

    Anybody got this one as well? Would love to see the GT3 Info.

    Re: Product Info and Training Doc

    Wow, thanx Ron
    This document will provide many nights of reading and studying.

    If I find this graph interesting. Porsche only mentions that the torque increases with the overboost function, but this graph shows that the horsepower output is higher between 2000-5000 rpm as well. Which I guess it has to...or not Maybe someone with a greater technical knowledge than me can enlighten us.

    Re: Product Info and Training Doc

    wow, thanks!

    Re: Product Info and Training Doc

    Thanks Ron! Great stuff!

    Only one funny thing-according to this document one of the key advantages of 997 Turbo over MB SL55AMG and SL600 is manual gearbox!!

    Re: Product Info and Training Doc

    This is a great document for anyone considering the 997tt. Thank you for posting, Ron(Houston) and Brian. It clearly explains the differences between the 997tt and 996tt, and how all the little changes add up. Some tidbits...

    . The change from 18" wheels to 19" wheels affected so many elements of the car including gearing and suspension. I guess that means 19" snow tires are de facto required for the 997tt....

    . The new electronically-controlled center differential lock should materially improve the driving dynamics of the 997tt vs the 996tt. The old viscous-clutch system could only transfer torque to the front wheels after the front and rear wheels were spinning at different speeds. The new electronically controlled system can transfer torque before that happens, and also when the system detects that one of the contract patches has run out of grip (eg., oversteer or understeer). The true test is in the driving, but the training brouchure makes a compelling story.

    . My favorite translation gafe is on p.2 "The optical authority emphasizes its performance potential." instead of "The visual authority....".

    . Greatest disappointment was the tiny luggage compartment. The luggage space in the 911 was never big, and it's a shame to see it get smaller, down to only 25.1 gallons for the US-spec 997tt due to the addition of a charcol filter. At least the gas tank got bigger, from 16.6 gallons to 17.7 gallons, and the cruising range increased as well due to improved fuel economy.

    . The spare tire is only available in Saudi Arabia, Guatamala, and the Virgin Islands. Which means you can get an OEM spare tire if you really want one.

    . The key benefits of the 997tt versus its competitors are identified as (a) more agile cornering due to shorter wheel base and lower weight; and (b) lower total cost of owneership including insurance. Additional benefits include good visibility and the 2+2 seating layout, depending on the competitor.

    . Porsche is very high on the "optional roof rack system", they list it as a key advantage vs. all but two of the competitors

    The document is labeled "Confidential" but I don't understand why Porsche doesn't make this document directly available to their customers world-wide. The only thing vaguely sensistive is section 15, which identifies the turbo's competition (F430, Gallardo, M6, SL55, SL600, and DB9) and provides relative selling points for the turbo with respect to each of thos cars. Even that was pretty tame and shouldn't cause a problem for Porsche.

    Re: Product Info and Training Doc

    Thank you, great detailed info!!

    "key benefits of the 997tt versus its competitors"

    Wow, that's all you see? How about the section on page 92
    entitled "Vehicle as a whole". That should excite any red-blooded Porsche nut. And how about the specific line on acceleration which gets a bold + = superior to competition?

    If it drives have as good as it looks in this spec, it'll be a tour d'force.

    Re: "key benefits of the 997tt versus its competitors"

    What a fantastic read. Thanks!

    You have it exactly right.

    Horsepower is Torque multiplied by RPM. Higher torque at a given engine speed HAS to make more power at that same RPM.

    Re: Product Info and Training Doc

    Awesome post!

    Thanks for the info!

    Agreed. Because overboost functions up to only 5,000rpm's and HP peaks at 6,000rpm's before which peak torque is already falling off, only PEAK torque is boosted with overboost, but PEAK HP is not. However, HP at a GIVEN engine speed (in rpm's) is ALSO boosted with overboost, so overboost boosts the engine's power output both MAXIMALLY and across the rev-range.

    Re: Product Info and Training Doc

    I have posted this graph before, and I thought it was self explanatory!

    Obviously not

    Well, the graph is self-explanatory to graph-reading forum members. Quite a few car enthusiasts are not math or engineering types and need a little jump-start to appreciate the beauty hidden in those lines on the checkered paper

    It is pretty self explanetory, I just thought it was strange that Porsche doesn't mention this anywhere in their propaganda. They are usually very good at pointing out all the fantastic features in their products

    And I was unsure whether the horsepower had to be higher because the torque has higher, which Mike so kindly explained for me. I knew they were connected somehow, but this torque/hp relationship is kind of a grey area for me
