GT3 vs GT3RS and no talk of prices

[Alpinestars]

Given that the new 991 GT3 RS is more differentiated from the 991 GT3 than any other iteration so far, is it surprising that the Ring times have the smallest difference of all but the 7.1 version?

From what I can see the times are as follows:

991 GT3 7.25, RS 7.20
997.2 GT3 7.40, RS, 7.33
997.1 both 7.42
996 GT3.2 7.54, RS 7.43.

5% more declared power. a lot more aero, similar weight, wider tyres - law of diminishing return.

Gap at Spa would be good to see.

Something that falls under the radar is how quick a standard 991 Carrera S is. Having seen laptimes on an American test, the difference looked barely beyond the Cup tyres.

You'd think the aero would make a difference, but everything else is fairly marginal. What is interesting is that Porsche big up the GT3 and GT4 aero package, yet a lowly Elise Cup R produces more downforce at less speed than either.

The 5 seconds from 7:25 likely was considerably harder to get than 7 seconds from 7:40 I would assume. Did the 6 RS come as standard with cup tyres which would explain a big chunk of the gap over the 6 mk 2?

Thinking about it, evo were talking up the very large downforce increase over the 4.0 but pop on cup2s on the 4.0 and the Cup sequential manual and that 7s difference between the 2 starts looking very bridgeable by the older car IMO...

Indeed, it's hard to see the downforce making any tangible difference - just as long as there is no lift that brings instability at speed. I would say the bigger aero factor is simply that 911s are so damn slippery. I think I read the 997.1 GT3 has a drag coefficient of 0.29, which I find astonishing for something with fat tyres, a big wing and touch of downforce. That where they gain a huge advantage over stuff like the Lotuses at the 'ring.

It would be interesting to see the comparative times of all these GT3s driven on the same day and all on Cup2 tyres.

No. Pirelli Corsa.

Makes you wonder what GT4 RS would do with a GT3 engine.

Will we ever see a NA GT 911 again ?

To answer your first question - nothing. Years ago, I think around 2007 Jurgen Alzen was racing a heavily developed Hankook Tyres sponsored Cayman in the VLN. He tried getting a Carrera V10 engine to go in, but the project went beyond a feasible deadline so that the car was ready for the 24hrs. He ended fitting a Mezger, but not just any GT3 engine, rumour at the time was that it was 4.0ltrs. It was certainly quicker than a few GT3 Cup cars, but ultimately it was as fast as some of the S54 engined Z4M Coupes or the Vulcan racing Viper or Corvette GT3. In comparison the GT3R and the factory backed Z4MCs were up to 30secs a lap quicker, which is an eternity as you know.

Second question - probably not

Just a 5 second advantage over 12.9 miles so around Spa's 4.3 miles... maybe a second?
