gt4 rs - 500hp - engine + gearbox from gt3
from july 21
very limited production
This would represent an unprecedented jump in power between a regular GT and RS?gt4 rs - 500hp - engine + gearbox from gt3
from july 21
very limited production
More that 75hp.Even the new 992 TurboS jump has been only 60hp and that's with Turbo power.
GT3 engine is dry-sumped with separate oil reservoir so there will need to have been significant change to facilitate this....
If they are using the 718 CS EVO intake/cooling solution from the rear quarter windows then the boot is going to be full of gubbins anyway, so put oil reservoir there makes sense, or maybe they put it in the frunk (a la GT2 RS Distilled Water Reservoir).
To make significant enough jump over the regular GT4 they will probably stiffen up suspension, so this really is becoming a pure track tool now.
Using the GT3 engine takes it above the performance capability of the race car in terms of speed.... so not sure this really stacks up in the hierarchy - unless we are also going to get a new race car..(which isn't due for a couple years yet according to the lifetime schedule of that car and commitment to the motorsport customers).

Exactly. It'll be a 450PS version of the current 4.0 with a PDK (or PDK-S if Porsche are feeling generous) gearbox and the air intake from the Clubsport race cars plus some firmed up suspension bits. Add a sprinkling of carbon to taste and job done. Not sure about a Weissach pack, but I doubt it on the "cheap" RS.
Porsche are very predictable, I don't see the GT4RS breaking the mould in any way.

No it won't. 80hp isn't overcoming the advantage of proper suspension and slicks....anonymous said:

I believe that is possible too. It will likely be a limited edition swan song for the Cayman before it becomes hybrid. Likely to be a lot more expensive than a GT4 and that price will need something to justify it. I doubt a 15 to 25 up increase would do it but a headline 500hp with a much higher red line, some RS Aero tweaks, lower gear ratios via the latest PDK and limited numbers would (imho) make an attractive proposition to a sufficient number of prospective buyers albeit at a much higher sales price. The Cayman let off the leash just to show what it is capable of whilst the 992 GT3 moves that model ahead so that toes are not trodden on.To put this in perspective, my heavily modified (but reversible) GT4 has cost me close to £120k in total but I have at least £20k's worth of original parts.
Everything I have fitted is Manthay or Porsche (Surface Transforms excepted).
If you look at the Manthey site, there is a specification for a 981GT4 MR road and track car ...
The question is, what was the new 4.0l engine built to be capable of (priced now at 718GTS level) ? All new cars must now have a particulate filter. It could make perfect sense to use the GT3 engine and just add to the price ... creating a clear halo Cayman (the GT3R is now almost mid engine) but can they turn the engine around ? They have.
Better to do this if they can than possibly over-egg the 4.0l ?? Porsche certainly don't need another GT engine platform.
The GT4RS will inevitably be compared to the GT3 and to justify a high price it will need both mechanically and emotionally, to be very engaging ...

Very good point re: using the GT3 engine. That would certainly add to the appeal and help justify a high asking price. The big question is will they ? I would like to see them do it rather than upgrade the 4L from the GT4 but it would be an out of character move. I am sure that there have been some very interesting conversations within the GT department about how this will pan out.Everything I have fitted is Manthay or Porsche (Surface Transforms excepted).

I really hope that they go all in on this project but I find it hard to believe that they will let a GT4RS match/outperform a 991.2 GT3 on track. Anything more than that will put the cat amongst the pigeons.
