See and hear the 991 Porsche 911 GT3

The Rennlist forum has come up trumps with some excellent, and hopefully reliable, details on the new 991-based Porsche 911 GT3. The information comes from an anonymous source who claims to have met Porsche engineers at the workshop you see above.

In dot point form here is what our new best friend was allegedly told:

• 3.8 litre engine is a brand new engine with dry sump (not DFI 9A1 or Mezger)
• Engine will form basis of next-generation Cup cars
• Redline 9,000rpm, tacho reads to 10,000rpm (as shown above)
• Power is more than 450hp (335kW), but wouldn’t confirm
• Completely different PDK transmission
• No Porsche Torque Vectoring (PTV) in test car pictured
• No Porsche Dynamic Chassis Control (PDCC) in test car
• Wide body chassis used from Carrera 4
• Car pictured is a Clubsport version with rear cage fitted
• Recaro seats, foldable (not one piece)
• Rear wing is fixed and manually adjustable, similar to 997.2 GT3, but has been refined
• Air scoop is centre feeding
• Car retains previous three-piece muffler, side mufflers look same as before, with a new smaller centre piece
• Test car pictured running Dunlop Sport MAXX tyres (245/20 front, 305/20 rear)
• Wheels feature centre locks
• New brake system, with enormous front calipers, disc is alternating drilled size
• Rear control arms look like the ones in the 997 GT cars
• ESC (electronic stability control), TC (traction control), sport exhaust, PDK-S (shown on the centre console)
• Nürburgring lap times around 7 minutes 30 seconds

That all looks pretty good, we’re sure you’ll agree. And judging by the audio clip below this new 3.8 litre engine sounds the business as well. In addition, there’s a few more spy shots after the break.
