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.

I'm sure the car will be something special, and no disrespect to your dream, but the RS engine is NOT going to happen. Taking bets now.......

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.

why impossible?
What s not technically doable in this setup?

Not saying they will do but it s doable
you're adding an entirely new rumor that displacement will be bumped to 4.4L. I was working off the most common assumption and information to this point that the engine will stay 4.0L.

YES! Very counter-intuitive as you are so used to lifting but nope.. keep the throttle pinned, press the clutch, shift, and clutch out.. amazing. Not sure why Porsche couldn't do this, but Cadillac did it. found a video

I have a feeling they will soon.

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.

Not very different from a normal powershift with a MT except that it apparently helps mitigate the screw-up factor for someone who is clumsy with the shifter.

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....

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.

Let's not forget that by having the computer assisting the shift,it will put less wear on the clutch and components than if you are power shifting. That will mess things up quickly.

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

So it's not a forever thing, but it will be around for a while - at least 2024.
Correct.

Default 911R

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.

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....

We are not splitting hairs Mike. LOL! But that's what I said in my previous post : there is a momentary loss of acceleration,but not as bad as when power shifting " manually " so to speak...
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

Drive safe,
