7:48 at the Ring on MPSC.

The 996 GT3 ran 7:49 on Pirelli Corsa System on AutoBild, and Sport Auto ran 7:54 on MPS2. For the few ones that know the difference between the Michelin PSC and Michelin PS2, this test might be interesting.

The test car has PCCB, Carbon Fibre Seats and no sunroof. Over 100 lbs lighter than the incoming U.S. version. Check the weight.

Was it in the rain??

Dry conditions.

The track was partially wet during the photo shot. I doubt anymore could break 8:00 with a wet track.

MPS Cup tyres provide about a 10+ second advantage over MPS2 at the Ring. This would mean that with the same tyres the 997 GT3 is actually slower than the 996 GT3 at the Ring. What happenned?

The 7.48 997 GT3 time with MPS Cup tyres is just two seconds faster than a 2004 M3 CSL with similar tyres. The CSL can be supercharged to 480 HP and fitted with upgraded brakes and suspension that would significantly reduce its lap times and make it faster than the 997 GT3, while providing a trunk and rear seats. The same mods and Cup tyres would even make a standard M3 as fast or faster than a 997 GT3. And cost about half the amount.

Porsche needs to do better.

From the article:

"The new Michelin Pilot Sport Cup tyres are not the same as for the M3 CSL , they have a different design and offer better wet handling. 1.3g is not the max. for supersports cars but pretty much enough."

Definitely, the MPSC as we know it, is not the same tire installed on the 997 GT3. Michelin has created a new MPSC with less grip in dry pavement, and more grip in wet pavement.

Terrific article! Erstaunlich!

Is it correct that the 997 GT3 is only supplied with the new compound Michelin Sport Cups, with no other option?

I am totally confused by this post.

NJ-GT where are you getting your times????

you said the following:
That the 997 GT3 7:48 at the Ring on MPSC. Correct.
That the 996 GT3 ran 7:49 on MPS2 by Sport Auto. - According to the above link it was the 996GT3 CUP car that ran the 7:49. The cup car has completely different suspension set up and lighter weight and is track use only.
That the 996 GT3 at 7:54 on MPS2 by Sport Auto. - Correct.

So the 997GT3 road car ran 7:48 vs the 996GT3 raod car at 7:54. Thats a SIX second difference on the new car over the old one, AND the 997GT3 road car BEAT the 996GT3 CUP car's time by one second SOOOO where is the problem?

I don't get yours or gete3's logic.

RR,

Please, check on that same link, the street 996 GT3 is listed above the GT3 Cup at 7:49 as well. This is the test I posted last year:

Nürburgring: Stock GT3 ran 7:49

The 996 GT3 RS ran a 7:43 with Walter Rohl.

The 997 GT3 and the 996 GT3 were not using the same tires. If you install the MPSC on the 996 GT3, or you install the MPS2 on the 997 GT3, the times will be different.

I made a correction on my comments. When the 996 GT3 ran the 7:49, it was using the Pirelli Corsa System. These are R-comp tires as the ones used on the 996 GT3 RS.

That GT3 in my link (which seems to be not working now) was not stock.

Here is a paste from the link. notice 392PS. Who knows what else it had.
The link underneath it looks like the same one you posted.
It may be a 996GT3 but it is not a stock car.

7:48 - 158.463 km/h - Porsche 997 GT3, 415 PS/1440kg (sport auto 07/06) http://www.supercars.net/PitLane?vie...ID=2&tID=91836
7.49 - 158.124 km/h - Porsche 996 GT3, 392 PS (AutoBild 2004), http://www.autobild.de/tuning/testbe...rtikel_seite=4
7:49 - 158.124 km/h - Porsche 996 GT3 Cup, 360 PS/1207 kg (sport auto 02/99)

That 996 GT3 was stock. The difference is that Autobild ran the cars on the dyno.

The whole purpose of that test was to compare a stock GT3, against the Manthey MM410 and the Manthey Race GT3. They put the three cars on the dyno, and the stock one produced 392 Hp.

It's no secret that the 996 GT3 power has been underrated. The driver for the test was Lucas Luhr.

XSpeedFreakX

Ditto on the 996 GT3 being underrated. Obviously though, we can't compare laptimes with different drivers. The only thing we can take from the Lucas Luhr lap is that the Corsa System tires surely make a considerable difference in handling and grip.

What did the Manthey car do on the dyno?

I doubt they would publish the times if slower than that of the 996 GT3. Doesn't seem that impressive esp with MPSC's. The cups should be good for and extra 5-10 sec.
