    997 Gt3RS Slower than 997 GT3

    Is the new 997 GT3RS slower than The Gt 3
    as it use the wide body From Carerra 4
    and the weight is only slightly lighter ?
    comments

    Re: 997 Gt3RS Slower than 997 GT3

    The RS is actually faster than the GT3 probably due to the fact that it is in fact "lighter" in some respects and has a single lightweight flywheel as opposed to a dual mass flywheel setup.

    Re: 997 Gt3RS Slower than 997 GT3

    Hej, hej... Maybe you should define "slower" a bit better... In a straight line? Around a circuit?

    The RS is faster in acceleration (0.1s to 100km/h) and I seriously doubt it is slower around a circuit, although I have not seen any numbers. The C4 wide body on the RS allows for a wider track on the rear wheels which improves cornering, thus I guess the RS is faster.

    Re: 997 Gt3RS Slower than 997 GT3

    I would think the GT3 has a higher top speed and better high speed acceleration (like 125mph to 175mph), due to the more slippery aero (assuming they really use the same motor).

    RS should be faster in low speed acceleration (0-100mph) due to slightly lower weight and light flywheel and should be faster around track due to wider rear and stiffer suspension.

    Re: 997 Gt3RS Slower than 997 GT3

    for the price and perception the gt3rs should kick all porsche products ass....obviously not the case if were talking .01 seconds related to anything

    Re: 997 Gt3RS Slower than 997 GT3

    Apparently RS is faster around the 'ring as it has both more traction (wider tires) and more downforce (that big wing) than the GT3. Don't have data but read it in one of the car mags - either Car or Evo.

    Does the RS have wider tires ? I think the only difference is the rear rim offset value, RS has ET51 & GT3 has ET68.
    2x 17mm , resulting in 34mm wider track.

    Re: 997 Gt3RS Slower than 997 GT3

    Both the GT3 and RS uses 305 tires. It's the stance that's wider on the RS not the tire patch.

    Re: 997 Gt3RS Slower than 997 GT3

    RS has wider track, but same rubber. RS has more downforce front and rear. Walter says is faster in high speed corners, likely due to track and downforce. I've seen no commentary that the RS stiffer suspension (springs), but it does have revised damping in light of the wider track, modest weight difference and more track oriented intent of the RS.

    I doubt the difference in track (circuit) performance is percepible behind the wheel, and against the stopwatch, only a marginal difference in laptimes. That difference is likely not achieved by mere mortals like myself.

    Many would argue that the GT3 is a better value, and I agree to a point. However, the RS will always be more desirable and cost of ownership will likely be less in the RS when it comes time to sell it.

    I think it was Easy who mentioned in one of his Factory Collection tour posts that during the factory build process (for a 911 engine) there is a natural variance in the BHP outputs. So all released engines have at least X bhp (official figure) but some can be up to 4% more powerful.

    Any engines yielding more that 4% extra are apparently sent back for de-tuning. Also, if the engine has an output of less than X bhp then they also sent back and subsequently a quiet 'word' is had with the engineer that built it!

    So specifically here; the additional GT3 vs RS rumour is that within the 4% variance, Porsche goes out of their way to put all the higher output engines in the RS. That way a GT3 could never outrun a RS.

    Re: 997 Gt3RS Slower than 997 GT3

    I guess 4% is around 16hp in that motor - might make a little difference. In the 996GT3RS, they actually had a different motor number code and some different parts, although all the marketing info made it seem that the motors were identical (probably so they didn't need to recertify the RS motors for emissions compliance, etc.)

    Re: 997 Gt3RS Slower than 997 GT3

    I think when Walter Rohrl tested the RS it lapped about 3 seconds a lap quicker than the GT3 around the ring, largely due to high speed stability apparently.

    That makes sense - and of course 3 sec. is not huge, considering a laptime well in excess of 7.5 minutes...

    Re: 997 Gt3RS Slower than 997 GT3

    The 997 GT3 RS is a lot more than a wide bodied 997 GT3.

    In the hands of us mere mortals the 997 GT3 RS will be a lot easier to drive nearer 10/10ths than the 997 GT3. We are splitting hairs here because both cars are a big step forward when compared to the 996 versions.

    What makes you say that? Yes, the wider rear track will add some stability, but at 10/10th's, that will mean very little, imho...

    I believe what you are referring to is the "color" effect. It's a well known fact that the Atlas Grey units have a greater BHP then other colors. If you don't believe me do a search here on Rennteam. You will find other threads to corraborate this theory.

    Yes, I am aware of this rumour also, so no confusion.

    I think if i ever get a Turbo then it will be in Atlas just for the possibility of 500bhp (well 499.2 to be exact, with the 4%!)

    Re: 997 Gt3RS Slower than 997 GT3

    It seems 996 GT3Rs 0-100 4,2 sec 0-200 13,5 0-200-0 18,2

    997 GT3 0-100 4,3 0-200 13,9 0-200-0 18,6

    In sportauto Nr 11 oktober 2006 they say in next issue
    they will show new 997 Gt 3 Rs super test nr 12
    available end november whne nr 12 arrives there is no information and no test

    is it so that Porsche failed due to Wider body the
    997 GT 3 Rs is slower
    i can hear alot of speculation for this matter

    i think the new 997 Gt3 Rs is slower due to wider body

    and it can not beat 996 Gt3 Rs

    Re: 997 Gt3RS Slower than 997 GT3

    The GT3RS is quicker than the GT3 and quicker than the 996GT3RS hands down.

    According to the latest Excellence issue:

    The GT3RS is faster on an oval track (track outisde of Paris where they had the introduction fro the GT3RS with GT3 and GT3cup cars) than the GT3 and the GT3cup.

    Also people have been concerned that the 7:42 that the RS scored at the Ring is only 3 seconds faster than the GT3's time of 7:45. But the article qualified this "slow" RS time with the following.

    The RS time was taken on a PUBLIC track day. Walter Rohrl had to pass 5 cars on the lap to score the 7:42. On the same day he tracked the Carrera GT at ONLY 7:37 (the record for the GT is 7:32) AND the GT3 was not timed that day, only the GT and the RS. So it stands to reason that the RS is capable of possibly doing a 7:39 (which is the figure Walter predicted in the EVO article from April.)

    So bottom line the RS is faster than the GT3 everywhere, and it is not much slower than a GT. Law of diminsihing returns.

    hehehehe ... very clever question
    answer : i think the GT3 is faster because its slower , the reason is the light weight of both cars , and the centre of gravity is beside both cars so by logic "both are faster than each other " ...
    just kidding .. but i think its clear that the RS logo isnt a joke by porsche.

    Re: 997 Gt3RS Slower than 997 GT3

    Rohrl's record for the CGT was 7.28 right?

    Unoffically, yes, but I think the official number given by Porsche was 7:32 (from an earlier session)...

    Diminishing returns indeed. These differences are negligible, especially to nonprofessional drivers like me.

    The real question is whether the GT3RS is worth the extra money, especially in NA where many of the extra goodies are absent.

    I like the idea of geting a slippery narrow body GT3 in whatever color I like - its a stealth bomber.

    By the way, did any of you who have the edition of Excellence mentioned in this thread check out the side by side pics of the rear window on the GT3, GT3RS and GT3 Cup Car at speed?!

    Re: 997 Gt3RS Slower than 997 GT3

    An orange GT3 RS went by (in the opposite direction - why!!) me on the Rocade surrounding Bordeaux. Even with my window closed, I could hear the roar. Those hips were blissful! WHAT A CAR!! So much for my slippery narrow body stealth bomber GT3 comments . . .

    Re: 997 Gt3RS Slower than 997 GT3

    Hello!

    I had the big luck to speak with Walter Röhrl. He told it to me in confidence! Walter drives the GT3 and GT3RS at the same day at Nürburgring and scored with the GT3 7:48 and with the GT3RS 7:42! But on the fastest point (Döttinger Höhe) the "normal" GT3 is a litle bit faster! I can't remember how much? I think he said GT3 283km/h und the RS 278km/h!? My conclusion is: The RS driver they ought to step on the gas in turns

    (Sorry for my English )

    Re: 997 Gt3RS Slower than 997 GT3

    This green RS is just so impressive . I bet it will be the 997 collector in the future !
