    If this is in fact the GT3RS then why does it have the side intake scoops like a turbo car, could it be possible the new GT3Rs will have a turbo engine??

    Normally aspirated 991 RSR has these too...

    Wouldn't it make sense to be turbocharged with future GT3-regs in mind? Not saying I'm praying for it, quite the opposite.

     It's been suggested and debated, but I think normally aspirated.

    The question is how much more power are they going to extract from the naturally aspirated 3.8 liter engine safely for a production road car. After all they keep on adding power with every gen car. Its a matter of time they either increase the engine size or go turbo.

    Some rumors suggest 4.0L with over 500hp...

    4.0 would be nice, the old 4.0 is still my dream car.

    Since there is no more GT2 (Turbo S is too fast) and given that the new RS looks crazy over the top... I know for sure it will be a great 4.0L machine with at least 550hp.

    Any thoughts on the fuel access door?  Is that final, or just a result of cammo/non-final part fitment?

    By the way, Porsche, I'm really liking the newer side intake shape.  Less bling, and reminiscent of the '98 993TTS.  I hope this is final.

    Personal taste here, of course.  YMMV

    I keep thinking, that fuel door is a fake, there will be a central tank filler door right in the middle of the hood.

    Does the front fender look more flared compared to the current turbo car? I think it is and that is why the fuel door is sunk in.

    That would be cool, but not so practical for a road car, I think.  Of course, the GT3RS is not so practical for a road car in other ways too.  Good suspicion there...

    4.0L and 550hp would mean 137.5 hp/L.  That is a pretty difficult target to meet - would be a new world record for specific output by naturally aspirated road-legal motor.  I think the current champion is the 458 Speziale with 133.  Porsche is at a big disadvantage by having to use 6 large displacement cylinders - easier to make high specific output with smaller cylinders (and smaller/lighter moving parts like pistons, valves, etc.).

    550 hp out of 4.0 L naturally aspirated, the car would scream If it reved Over 8000 RPM.

    It would likely need to rev over 9,000 rpm to make that much power
