They didn't need GT3 R development......They found easy HP in 4.0L by just adding Dundon Motorsports headers to upcoming 911R. Porsche felt that in light of how trustworthy they are regarded by the Feds that they can easily pull off running no cats.

This car seems to be special for sure... I think 500 - 600 cars, 4.0 rs motor with some racing parts (GT3 R) 525 hp,a diferent exhaust system, a lightweight interior ( 70 - 100 kg in the spirit of the original R), lightweight body panel (carbonRS parts), special front fender, RS hood and magnesium roof etc.., manual, no RWS, No wings (like the original R) a pure car... OK i dream
but...the answer arrive quickly ![Smilie](https://rennlist.com/forums/images/smilies/smile.gif)

FWIW,the new Cadillac sport(forgot the name-maybe someone can chime in) comes with a 6 speed manual transmission with rev matching on downshifts and no lift on upshifts. The technology is there and perhaps Porsche will start offering it with the 991R and 991.2 GT3 with a manual transmission. That way,nobody will feel the need to cry about how much time they would lose for lifting while changing gears.
P.S. Found it : it's the 2016 Cadillac ATS-V.

GT3 475/3.8 L = 125 HP Liter
GT3 RS 500/4.0 L = 125 HP Liter Incresed Stroke AND Reduced max RPM from 200 to 500 RPM less = same piston speed
550HP/4.4L = 125 HP Liter Increasing bore is
aame piston speed
why impossible?
What s not technically doable in this setup?
Not saying they will do but it s doable

I have a feeling they will soon. ![thumbup](https://rennlist.com/forums/graemlins/thumbup.gif)
Bear in mind that Porsche didn't offer automatic rev matching on downshifts in the early 991s either. The first 991s came in 2012 and Porsche started offering rev matching in late 2013 991s.

Although the throttle isn't lifted by the driver, this type of shift can't be as quick as that in a dual clutch gearbox where the next gear is already preselected and power flow is almost completely seamless.
Probably kind of fun though....

Not very different from a normal powershift with a MT except that it apparently mitigates the screw-up factor for someone who is clumsy with the shifter. Although the clutch pedal isn't lifted by the driver, my guess is that the technology still disengages the clutch briefly to complete the shift. Regardless, this type of shift can't be as quick as that in a dual clutch gearbox where the next gear is already preselected and power flow is almost completely seamless. Probably kind of fun though....
To your second point,of course it's different and not as fast. I'm personally not excited about this technology,as I'm not excited about rev matching on downshifts in my GT4. That's why I'm rarely in Sport mode. I prefer to do it myself.

This is my understanding...
918 owners who've kept their car greater than 3 years are given 10 years of VIP. Less than 3 years and greater than 6 months gets you 3 years of VIP. Less than 6 months of ownership gets you nothing.
So it's not a forever thing, but it will be around for a while - at least 2024.

from reliable sources: RS Motor. GT3 Motor cannot be MT. High rev motor was specific to PDK. The engineers went back to the drawing board to try and put a MT in the 991 GT3 around the time of the intro due to all the negative press and couldn't do it. Then the 2014 fire recall problem. When they were compelled to redesign the GT3 problem motor for the 991 RS they engineered it for either PDK or MT. That's why we hear that a "future" GT3 will be available either way.
Specs can change but I was also told RS double bubble roof. I also heard 550hp. I thought it was a bad Skype connection because it doesn't "feel" right. But there may be some confidential piece of paper that states it since now I'm hearing it elsewhere. It may also be a misprint. I don't believe it will have more HP (and probably less) than an RS. I also heard it will be a narrow body car.

But,my point is,the technology is out there for those concerned with the momentary loss of acceleration when manually upshifting.

Not to split hairs but there is a momentary loss of acceleration if the clutch is disengaged, which I assume it is with this technology. Quicker than a normal throttle lift upshift, but not as quick as PDK. Something to be concerned about? That's a different issue....![Wink](https://rennlist.com/forums/images/smilies/wink.gif)

Also,I've edited my previous post to include a few points about accelerated wear when power shifting.

Thanks for sharing!
It's only 200 rpm higher, but ultimately the pistons are moving slower / same speed, if I recall correctly.
So, why would the RS engine be more capable to be mated to a manual transmission than the GT3 engine? Especially considering they were both made for PDK-S from the beginning.

I highly doubt that's the case. Porsche has always had the capability to fit a manual tranny with both engines. They just chose not to because of costs involved and because the car is faster with PDK. Simple really...

Found another article about the 911R today. Nothing much new other than what we all know, it will be revealed this March at the Geneva Car Show
