Default Bone Stock 991 vs. 997 Carrera GTS Race Car Lap Times

If I didn't see it with my own eyes I wouldn't have believed it but the car was literally only 2-3 seconds slower around Palm Beach International Raceway BONE STOCK on street tires! We didn't even give it the benefit of race rubber. I think I know what would have happened.

The 997 race car had a brand new motor and therefore had a stock ECU file in it; everything else though was in race trim.

What an amazing car!

PHOTO CAPTION: My turn? My turn? My turn? I know I am totally stock and not a race car but I'm also only 2 seconds slower around here than my big brother!!!! Imagine what I can do when I grow up!!!!

What advantages does this motor car have over, say, a train - which I could also afford?

That's a 991S, right?

I thought the 991S was to out track a 2010 GT3. You're saying that it was outrun by a GTS?

I understand that as I think the 997 GTS is a better car. And the better looking car of the two in the photo.

I'm sure John will clarify, but my understanding of his post is that the GTS in the pic is a stripped, race-prepped car on race tires. For a stock street car on street tires to even be close is very impressive. My take is that a 991S in similar race trim to that GTS would blow it away.

The 991 S will easily best a 997 GTS on a race course driven by the same driver.

The difference in standing start acceleration is tiny- within the variations of drivers and roads, so long as they are both PDK.

Either with PDK will walk away from either a manual with ease.

The Carrera GTS in the photo has full suspension and where things aren't spherical they are delrin, coil overs, race tires, lightweight flywheel, limited slip diff, eliminated PSM intervention, pulleys and headers. The ECU was stock.

The 991 S had zero upgrades and given that it's on a 20" wheel/tire it's even more impressive. I would assume that the shorter 3rd and 4th gears are more of an advantage than I give them credit.

What I can deduce from the following is that a 991 S would easily best a 997.2 GTS around a race track and I think that a 991 built out to the same exact specs as our current 997.2 GTS would probably pick up another 5 seconds around a place like PBIR giving it maybe 2 seconds over the existing race car if it was apples to apples.

Was the GTS on the GrandAm slicks and the 991S on the Michelin Pilot Super Sports? what kind of lap times were these two cars doing at PBIR?

Porsche's own testing with the 991S and all the go-fast options on MPSS tires lapped the Ring in 7:40, same lap time as the 997.2 GT3 and just 1 second slower than my Scuderia. Then Horst Von Saurma tested again at the Ring and he got in the low 7:40s with a 991 S.

Randy Pobst just lapped a 991S a few weeks ago in 1:39.3 around Laguna Seca on the slower tires (Pirelli PZero), faster lap time than the lap posted by the 997.1 GT3 with another Pro-Driver (Angelelli) at the wheels (on MPSC tires). On MPSS Pobst could touch the 1:38s at Laguna Seca.

991S is impressive, and currently one of my favorites multi-purpose cars, the only problem is that it is priced a little too high.

The 991's weight has my attention. Not crazy about PDK end even less in the fake 7 speed.
Randy post lap was only a second or 2 slower then Van overbeeks's lap in the GT3RS.

maybe they can put the Turbos 6 speed in for the RS?

fast car for sure, even though PBIR has a very unique and boring design. 2 big sweepers, where mechanical grip will give you good advantage.

Stock Pirelli rubber for the 991, complete with plug in the LR that wouldn't hold pressure so it did this with a leaky LR!

I think we can all agree that the 991 with street alignment and street rubber will lap faster than a 997.2 GT3 with the same rubber and alignment, even tho it benefits from 50 more hp and a shorter final drive ratio on 19s? Or 18s? And an LSD from the dealer.

The 991 motor is rated with 10 lb/ft of torque more and I think it's prob in the tuning and the different camshafts.

Someone's point about PBIR was right; it's a short track with much turning so an agile car does well there. To me the single biggest advantage is on entry with how well the car points and gets to the apex - its here that you get on the power so much earlier but the stock Pirelli rubber wasn't up to the task of 120 degree track temps. And the track is abusive. No fault of the Pirellis.

What a car! It pulls like a champ, stops with amazing pitch and turns in like a Cayman. They did their homework this time! Can't wait to have this car on track in October after the season ends. For all of you patiently waiting for the GT3, you won't be disappointed.
