Porsche writes: 315kmh Vmax
Speedometer maximum in real life is: 305kmh (which is with new tires below 299 GPS)
(measurements done also downhill...)
7th Gear rpm max is: 8.300rpm
soft limiter kicks in - throttle body closes a bit - hearable
so around 450hp at Vmax - electronically limited
i would say thats a thing.
And Porsche could tell us a couple of words about it - or downscale their Vmax in the papers.
clearly its still a hell of a car!
but we don´t want to be fooled - as Ferrari and Lambo customers.

You are fools because you don’t understand basic aerodynamics and HP. What was the headwind, what were the tire pressures, was the fuel new or old or a blend.
Just stop with this nonsense there is no soft limiter at 8300 rpm - if the car pulled timing it will be for another reason eg fuel, temp air flow.

So you are saying Porsche are engaging in misleading or deceptive conduct in commerce or industry.

So far there have been 3 instances with 3 different cars, 3 different drivers and at 3 different times and locations all arriving at the same result.
What again are the odds for you being right in each one of those?

Its been explained to you, as have the differences in RPM vs velocity for the GT3 Vs 4RS. If you don’t understand the engineering and physics explanations please feel free to offer a credible explanation lol
You can’t - exactly like those that claim that Porsche under rate their engines.
I guess those of us that have had cars with this engine and gear box for many years must have missed the special top speed 7th gear limiter - that’s only available in the 4RS.
Perhaps you should take legal action against Porsche for misleading or deceptive conduct given the Vmax is stated in the spec sheet for the car.
If you really believe there is a problem - run your car and others on a MAHA dyno and demonstrate that the car is not making 500PS at the crank. You could call Porsche and ask them if there is a soft limiter at 8300 RPM in 7th.

Question for those who’s gone through the Porsche process of tracking. I’ve just been noticed this morning I’m now in phase 2… so what exactly does that mean? Lol.
what does schedule production mean? Like any day? Next week? My original date was end of august for entering body shop.

4.0 is not 4.0. IIRC there was the burner, the .... So your years of experience is with a different 4.0 motor; not this one.

I’ve NEVER heard Porsche overestimate performance on ANY of their cars. The other way around, always underestimated performance figures. This is kind of shocking. Not that I will ever get near such speeds in my country, but WTF??? What about my bragging rights down at the pub! This was supposed to be the first +300kph car of mine!!!!

Believe there's a German law regarding such things, is there not?

I believe the Ti WP tips are for appearance only. Both in shape and the blue temper color that will form from heat and oxidation. Ti is less dense than iron so if the Ti were the same shape and thickness as the iron then the Ti would only be about 2/3 as heavy as the iron. But the Ti has a more complicated shape with fins connecting the inner and outer pipes so difficult to say which is actually heavier on the GT4RS. I think the noise will be almost the same between the two versions.

I’m torn. I think the carbon hood is cool but sometimes looks a little “tuner”. The big stripe will help that to look more factory GT2. Am I correct if you pick Weissach package you have to take the exposed carbon hood? I would prefer a painted hood. That said I would consider the Porsche factory skinny stripe I have had on other GT cars. If you use a contrasting color center stripe over carbon that works with the body color that might be nice. For example shark blu, red calipers, black carbon hood red factory Porsche center stripe. Would love like hell to pull off red calipers on PCCBs! Black is better than yellow but is still hidden. 🤷♂️

I agree. And lets not forget that if the carbon fiber air intake scoops had a performance effect then Porsche would have included them with the Clubsport GT4RS. I think the WP is somewhat for additional profit along with more choices especially for those who like cf exposed, If a person really wants magnesium wheels they have to take the WP. The cf air intake scoops makes it look like you are getting something performance wise for your money. Clever marketing, and I think OK for Porsche to do this, and be profitable, and give us these great cars. Those who would have liked the magnesium wheels as a stand alone option can at least get PCCB to save on rotating unsprung mass.

If WP added some more performance I would have considered it, however as its cosmetic only i'll save my money and wait for a Manthey racing kit for the car, it'll probably be a similar cost to WP but will actually have some performance gains.

If the carbon airbox and intakes were available without the "package", I might consider skipping it... It seems that much of the wonderful noise that the 4RS makes inside the cabin is due to the carbon airbox.
Sure, it's hard to justify the "value" in the $13K Wiessach package, particularly from a performance perspective. But if one is lucky enough to score a decent timeframe 4RS allocation without paying the moon for it, seems even harder to forgo a cosmetic and driving experience upgrade like the Weissach package, assuming you like the visible carbon and race-tex upgrades it offers. I'm checking the box on mine.

I believe AP said in the TG video the scoops had a small ram air effect at higher speeds.
