    New 991 GT3 info

    Found this info over on Rennlist.


    991 GT3

    Date: 18 February 2013
    Source: unnamed Rennlister
    Location: Unknown


    Information after discussion with the test driver and engineers and watching/touching the actual car

    It sounds incredible. Exactly like a cup car.

    Completely different PDK

    Engine is a bespoke motorsports block, and the basis for the next gen Cup engine. Dry sump.

    Yes, it's not the DFI 9A1 and it's not the Mezger. It's a new engine!

    - RPM to 10K, redline 9 dead, 3.8L engine. Power is north of 450hp but they wouldn't say exactly.

    - No PDCC, no PTV *at least not in this car

    - New rear wing, very similar to 997.2 wing, but up close it's more refined

    - Air scoop is beautiful, center feeding

    - Car is running Dunlop Sport MAXX, 245/20 front 305/20 rear

    - Car retains traditional 3 piece muffler, identical side mufflers as before but looks like a new, smaller center.

    - New brake system, front caliper is ENORMOUS, disc is alternating drilled size.

    - New recaro seats, foldable (not one piece), car was a Clubsport version fitted with the rear cage

    - Ring times are right around 7.30

    - Center locks

    - ESC (electronic stability control), TC, sport exhaust, PDK-S (on the center console)

    - Wide body chassis from C4

    - rear control arms look like the ones in the 997 GT cars

    991 GT3 details leaked + photos - 9000 RPM redline, GT1/Metzger replaced, 3.8 liter, PDK, ~450 horsepower

    So more 991 GT3 info is getting out and this time courtesy of a Rennlist member we have some photographic evidence to go along with it. Let's start with the most noticeable which is the 9000 rpm redline. PorscheBoost can not think of a production six cylinder motor for a street car with a higher redline. The last time 9000 rpm was seen in something without a prancing horse and 1/4 million dollar price tag happened to be the Honda S2000 which did it with a much smaller 2.0 liter four-cylinder motor and Honda actually ended up reducing the redline. This motor is going to have insane top end pull.

    And that brings us to the fact that the GT1/Metzger block is being retired and this is a new motor. This motor will be the basis for the new race cars and does not feature direct injection (thankfully!). 3.8 liters of displacement and around 450 horsepower just as reported from dealer leaks a couple weeks ago.

    The ring time will be in the 7:30 range with 7:34 reported previously as per dealer information. Center locking wheels are standard in sizes of 245/20 up front and 305/20 in the back with Dunlop Sport Maxx tires.

    PDK is standard, no surprise there and a great move for the performance enthusiast. Porsche stability control programs (which of course can be turned off) are standard.

    The 997 GT3 is routinely praised as the epitome of the 911 evolution and arguably the best 911 ever made. It seems Porsche has managed to raise the bar with the 991 GT3. With these specs, this will simply be the closest thing to an actual cup car for the road money can buy. Porsche has done it again. There is no substitute.

    The RS probably will be a 4.0. Probably over 500 hp... with PDK. Going to flat out rip.

    According to those specs it likely is worth it.

    But what about the Turbo/Turbo S/GT2?!?!? The GT3 is a street track toy, but the Turbo'd 911 is always the HP sled

    Details on that will come later. Seems the GT3 will make its debut in Geneva and then the Turbo will be Frankfurt.

    Waiting for the GT3 RS - if it's above 500hp I'll be getting one.

    So this thing can't be ordered with a MT any longer? Is it ONLY PDK?

    It would be a heartbreaker for those hardcore MT GT3 owners out there, if it is only offered with a PDK. After all, this car is supposed to be as raw as possible while being street drivable. With that said, I hope they keep the MT, Porsche MT's are some of the best, and they just came up with that 7spd MT. I realize the PDK is mighty fast, but some people just have to have a MT. It would be amazing to row thru gears with that engine.

    It pretty much comes down to it being a business decision: http://porscheboost.com/content.php?...or-the-991-GT3
