That will make this car a minimum of a 14-15 car. We did some back to backs in testing of an h-pattern vs a sequential gearbox in our BMWs in 2008 at Sebring. The sequential gearbox with no lift shifts was 1.5 seconds faster than the h-pattern in shifting alone. The .6 faster 0-60 already shows the extra speed this car has over the 997 4.0.
That GT4 race car mention had me thinking to cancel my GT4 order!!
What sort of spec and pricing do you expect? Rumor I heard is that it'll have real sequential gearbox (rather than manual or PDK) which is rather pricey to run (if like one in GT3 Cup).
I'm curious to see what sort of Go-Fast parts it may have that can be retrofitted to the road car...
I like what I see but am waiting to hear some reviews from the usual suspects...If I were to be crazy enough to pursue this (my wife would probably kill me since I've only driven the GT3 3 times so far, it's winter here), mine would be Barney purple...
If the price is right, it has my name on it. A LOT can be done to make a car better for the track if the requirement that it be usable on the street is dropped. Better dampers, stiffer springs, more aggressive aero, less weight, better safety, etc.
If you compare the price on a GT3 Cup vs GT3 and use the same ratio on the GT4 it'll be around $160k.
although many are saying they wont buy one, we know the RS will sell like hotcakes as always. i look forward to having one even though i dont have an allocation yet
I hope the downforce will be the biggest difference in the RS vs GT3. I'm also hoping the wider track, aero package and suspension of the RS fixes the squirmy behaviour of the 991 GT3 under very heavy braking.
Adding the Crawford wing to my GT3 made that tail wagging go away coming into T17 at Sebring close to 150 MPH. It produces at least the same Downforce as the GT3RS Wing.
What are these numbers? can you explain? thank you
These would be peak piston speeds based off the length of the stroke, 360 degrees of rotation & the max allowed revs per minute. In one full "stroke" an engine's piston must come to a full stop x2 times (once each at the top & bottom of the stroke) then accelerate/decelerate quickly enough to cover, I think, 2x the length of the stroke. As rpm increases, this puts bigger, and bigger stress on the parts.
Google something like "peak piston speed" and you will find stuff/threads like http://www.eng-tips.com/viewthread.cfm?qid=85349
where stories of mechanical failures are caused by excessive acceleration and deceleration forces.
I guess one question is, "Where did the additional 200cc come from? An increase in bore? Stroke? Or a bit of both?" My guess would be bore only, but that's just a guess in which case rpm would have been reduced to allow for (probably) slightly more mass in the pistons due to slightly larger size, but I'm just guessing. Or as others have suggested, maybe Porsche expects the "RS's" just to be driven harder by the more manly men & women who own them, and think they need a greater margin of safety to get the motors past their warranty periods.

GT4 Cup will be at least 991 GT3 money when compared to the competition. The Lotus Evora GT4 is GBP125k. I expect Porsche to charge a little more than GT3 money for the GT4 Cup - my money is on $160k.
