It is possible if they don’t use heavier 8-spd PDK from 992 Carrera (either lighter 7spd PDK or lightened version of 8spd. Manual should continue with same 6spd box). But weight loss tends to be expensive, so just because it’s possible doesn’t mean it will happen...

I've heard that manufacturers have a built in 10-15% rpm cushion from the max and drop it down as to keep the engine from expiring prematurely. How true that is can be anyone's guess.

That article is nearly a year old, prior to the new RSR being announced with 4.2L

I didn't mean to imply anything that extreme. They only need to add 20hp to get to 540 (less than 4% bump) - so adding only 350rpm to peak power (to 8,750 rpm) should be plenty. Whether they want to and can raise redline by similar amount is unknown.

With the E46 M3, BMW made peak power at 7,900 rpm, while redline was only 8,000. This is not the best way to go (you fall too far below peak power on an upshift), but does allow you to make power without grenading the motor (or so went the theory)...

Nonsense.

It didn’t grenade the motor. It was simply an oiling issue caused primarily by user error - i.e., driving the car.

There is no way in hell that the 992 GT3/RS will rev beyond 9k revs..If indeed it has 540HP is will be done by increasing capacity to 4.2L..Its the only logical outcome unless Hybridization or turbos are employed.My guess is 4.2L NA and 545PS(540BHP) and retain the existing 7 speed PDKS to keep weight down.The 8 speed 992 PDK is an extra 20Kg which will be totally unacceptable in a GT 911.
Conspiracy theories make for fun reading although need to be taken with a very large pinch os salt.!

Hard work keeping up, and law of diminishing returns and bank balance.

I think you nailed it. That would imply GT3 reveal in Geneva or Goodwood.

Unlikely to see engine relocation - too costly for production.



Doesn't sound like a full bump to 4.2 is in the cards but it would be nice.

January 2019 article; preceded announcement of 4.2L engine in RSR

It sure would be crazy. The outgoing 4.0L RSR spun to 9500 for the 24 hour races. Same size pistons in a $200K car (vs. a 991K euro car) that has to have a warranty = never gonna happen.

most of weight gain in 992 carrera is from two things. 1- 8 speed PDK, 2- extra steel supports for 991.2 hybrid motor.

(Neither of those things is necessary in a 992 GT3 car, so other than a slight wider track that will add a few pounds, hopefully the 992 GT3 won’t be that much heavier than the 991.2 GT3.

If we look at Dundon’s headers for the .2 3RS I believe they pick up 25hp and 35 lbs/trq just with better flow. Add their intake manifold and I think it goes to 30 hp and 40 ft lbs trq or more.

But...it would make sense to go to 4.2 since the new RSR is 4.2 and for Motorsport consistency and enthusiasm


I’m not sure where they lose 100 lbs though.

Intro some time in first half of 2020 makes more sense (with late 2020 deliveries as 2021 model year in US).
It's just an educated guess based upon historical releases. I think we all agree that they won't release the 992 GT3 in 3 months at Geneva, so you think they'll release at it Goodwood or Frankfurt or LA?
