Spyderidol:Hi-Res so you can examine the front.
Hmmmm, the side "vents" no longer look like (fine) mesh in the hi res pic, and the centre vent looks as if it's been taped over to reduce the cooling effect, as you might for a test on a cold day?
It must be an EV.

So the large extractors in the "trunklid" allow them to get enough air through just a central radiator to control engine / transmission temperatures.
Come to think of it, that arrangement worked on the old GT1s, which were good for over 600hp.

Spyderidol:I think they create an outlet for the flow of air coming from the front grill. In through the front, cooling the radiator, and out through the vents in the trunk lid.
Yes, there are ducts leading the air along the path you describe, but I had assumed that some air was also still ducted through side rads and into the wheel wells, as was the case with earlier RSRs, and still is with the street GT models.
I guess the newer arrangement would help further improve front end downforce, as well as optimise weight by using one large rad instead of 3 smaller ones.

Spyderidol:olli:Any hints in that as to the likely engine configuration...?? I guess not really.
None, but I'll go out on a limb and predict a Turbo...or two.
Probably lifted directly from the GT4 road car. Detuned, of course. It's power would violate all race regulations otherwise.

I will say 4.0L NA.
If they go this way, I predict a real thumping from the competition. They will once again be completely reliant on BoP in order to remain at least slightly competitive. In other words, little will change in relation to the current status quo. I suspect you are most probably correct, but I hope you are not.

Porsche should have learned their lesson: Air restrictors can control hp, but they don't effect torque. This is one huge advantage that Corvette and other bigger engine opposition has had in the past (before Turbo). Now with Turbo's (which are essentially torque multipliers) in most of the serious opposition (Ford and Ferrari), it seems to me that it would be a fools errand to try and compete with what has often been the smallest NA engine of the field.
I think the main drivers behind that decision (if they do take it) will be (as usual) money and marketing (dependent on what is planned for future GT3/2 cars).
Porsche of course, will claim they have seen something in the regulations that can provide them an advantage. They are usually very good at this, but....times they are a changing and regs will move in the direction that most want it to move.
It's not so much about power but also torque. Spyderidol is right. New GTE are limited to around 500hp anyway I think. We lack torque compared to the Aston for example which has a bigger capacity, I could really feel it in the raidillon last weekend at Spa because it's up hill.
Our car has about 460hp with a massive air restrictor. the red line in my 458 GT2 is at 6800 rpm.
Yes you read that right, 6800 rpm. in a 458. Fucking sad...
Without restrictor the car is good for over 600hp at 9000rpm. But it would be a lot quicker than the LMP2s...
Futch, that's shocking! Need to let those LMP2 cars get faster I guess!
On another note, apparently Porsche has received a permission waiver to move the gearbox BEHIND the engine for the 2017 GTE RSR.

Which means that they must have received a waiver to move the engine forward.

Anybody seen the movie about the Le Mans package that was tested at spa (for the 919)?
It featured the new headlight design and it was mentioned that they are fantastic for determining/viewing the apex.
I noticed that the central stripe of the light cluster differed in color between blue and red, anybody know why this is? To see which of the two cars is coming up (sometimes difficult to see from head on).

Hi Spyderidol,
just a quick note on the competitiveness of the new 991 GT3 R, the customer car for (semi-pro) GT3 class teams. The factory supported Team Manthey with works drivers raced it in last weekends 4 hour VNL endurance race at Nürburgring.
In qualifying practice on the 20 km track, they were 5 sec off the pace of the pole sitting new BMW M6 GT3 and right in the pack with the new Audi R 8 LMS and the Mercedes AMG GT3. (8:00 vs. 8:05)
In the race itself, BMW came in first, second and third, Audi fourth. The GT3 R were fifth and ninth, respectively. The GT3 R's fatest lap time was 5-8 sec off the pace of most of the top BMW, Mercs and Audis. (8:05/07 vs. 8:13)
After all the effort that went into the development of a competitive GT3 customer car, this does not seem to augur well for the GTE class effort, barring BoP miracles...
