be the 2.5 turbo lump at about 380bhp or the 3.8 NA lump at about the same.
There is no way Porsche are going to give a Cayman over 400BHp imo.
They might have Kers lag fill on the turbo though to show off the new tech.
I think that is is spot on - and makes absolute sense. ERS Torque fill McLaren P1 style.There is no way Porsche are going to give a Cayman over 400BHp imo.

Would be a perfect demonstration and translation of the LMP1 919 Car technology applied to the road.
This is the reason why Porsche decided against F1 and went LMP1 - because the technology is more relevant and more direct applicable to the real world.
I, for one would absolutely love that.

Could they go for the V4 turbo from the 919 with a bit of ERS tech?
Motorsport derived/inspired.As seems to be a growing trend now, if they put the 'Hot in the V' then it could work as packaging will be tight and tidy.
Cooling solution would need to be COMPREHENSIVE and we haven't seen much in the way of bodywork changes from the spy shots to cater for extra cooling inlets and outlets.
Sounding more and more like a bigger N/A

I've got a deposit down for one of these should the media predictions become a reality. the idea of a Cayman on a diet with more power and a race honed chassis (the initial reports are that it'll be homologated for competition) rather appeals, as the 911 gets fatter and more tech laden.
Agreed - I still haven't committed actual cash but my LOIs been with them for a while now.Fiorano - I was at the PEC on Wednesday trying out the new Cayman GTS (very nice car). One of the instructors suggested that Porsche is looking to enter GT4, so will need to homologate somethinga apparently (I've no idea how the rules work) - Cayman GT4 is what he believed they would be building but was very non-committal beyond "something is being worked on".
Thanks J-P. Thats interesting to hear. One hopes that this is going to be the case and its not just another name grabbed from racing that has no relevance to the actual car situation.
V8KSN/Olber. Indeed, I would say that 420hp range would be more likely needed looking at that list versus weights. Given GT4 regs a cayman race prepped would be up in the 13XXkg weight bracket.
Does anyone think this car (if it is for GT4 class) will finally see some proper rear suspension design added to the platform?

If Porsche DO make this car then they will have to diffrentiate it from the 991 GT3 and make it ....how do I say this.... less technologically advanced as they will want people to buy the all-singing, all-dancing 991 GT3 with its RWS etc.It could be a really good car if its a manual, NA 450HP with passive suspension.
Marketing could pitch it as a GT3 'wannabe' so the accountants are happy.
V8KSN,
I was meaning multilink rear suspension (or double wishbones) instead of the current strut design setup. I hadn't even progressed as far as the idea as to whether they may fit RWS but since it seems to be going onto everything its an interesting point you raise.
Constantly poor Cayman sales, A potential tap in to an as yet un exploited customer motorsports stream. Those two would seem to be enough to make the car worth a punt from Porsche, I guess time will tell if its the case and howe serious they actually are with it.

Mmm, not convinced.......drove the latest M3 M4( out of interest only).....lag virtually non existent and reasonably linear power delivery too. Appears lots of the new age M3 salivators actually prefer this green engine to the E90 92 fossil guzzling V8 screamers (which incidentally some appear to be recently exploding BTW)Biggest problem with the new turbo substitutes is how they sound.....and no matter how much 'authentic' superficial piped induction engine noise is cabin fed, the general consensus is it sounds s
it.....
The thing that makes me say 400hp rather than 450hp is the lack of blistered arches. As the car will probably run with the gt3 centre locks the car would surely need wider arches to take 305 rubber, centre locks or not.
Can't see them placing 450hp into the car with 275 section tyres.

ah you calling me a liar ? my local OPC had 2 'letters of intent' already, and 1 deposit, so i was the 2nd customer leaving a deposit which will guarantee me a car. all this is refundable if i don't like the spec of the car when announced, or indeed if it's never actually built. next i suppose you'll want me to send you the 'kin paperwork ?
nope but there is no need to give money to OPC's to secure a car atm, I have a 'letter of intent' and that's good enough to get me a car, you normally leave a deposit when the car is a real car which is normally 6 months before you can even order one. So why leave a deposit ?fioran0 said:

No worries - I'm hoping it's going to be a properly lightweight Porsche Motorsport special and not some pointless marketing exercise. If it's the latter, I'll pass! Rumour has it that it will be a 3.8 engine with around 380 to 400bhp. Awesome if true but undoubtedly expensive!V8KSN/Olber.

Me2 ... Letter of Intent and no deposit. But I'm very excited by this. The car should surely be under 1300Kg's ??I can't understand why everybody gets hung up by noise. It doesn't mean fast, and it does compromise circuit options.

My Boxster has been turbo charged and was described by 991 & Porsche World quite positively.it....."Predictably, the first thing you notice with this car is the noise. Quite simply, it makes one of the very best noises I've heard from the tail pipes of a Porsche. At one point during the shoot, David drove his car backwards and forward for the photographer so he could capture a panning shot. Having an idle moment I set off in search of some mobile phone signal and climbed up onto a hill overlooking the road where we were working. I must have been about 100 metres away by this point, but the sound of this Boxster was loud and rich in tone: if you’d been facing the other way you’d have guessed that some exotic old Porsche race car was flying past behind you. It’s a deep sound, far more so than you’d normally associate with a Boxster, and when the car is being worked hard there’s the slight chirrup of the excess boost between gears."
So it would seem that maybe the problem isn't that you can't make a turbo sound good, but that they don't want to. Piping the noise into the car makes it sound good for the enthusiastic driver, but keeps it nice and quiet for the car hating general public?

It is one thing to read that journalists aren’t too happy with the sound the engine makes but it’s another thing to read a comment like this. Part of me wants to see you post this over in the M forum to see what happens.As for the GT4, I would hope it will be a swan song for the six cylinder Cayman/Boxster. Using it as a test platform for new hybrid/turbo 4 cylinder performance would make a lot of sense in many ways but it is still too early for that.
They would probably have a hard time getting the performance below 991 GT3 levels with a mid engine 400 PS turbo 4 and full use of torque vectoring as pioneered in the 918.
The rumored mid-engine car between 918 and 911 would be a perfect candidate for that kind of technology.

My Cayman S 'loaner' with its quite intrusive sports exhaust does sound convincingly authentic, presumably all natural sound, almost resembling a 458 on the overrun. Shame the top end performance is understandably nowhere approaching the 911....
On the subject of 911s, it would be interesting to see if more people would buy Turbos if they sounded better...whilst the 991 is an improvement over the 997.2 which in turn was an improvement over the 1, none of them sound particularly good, contributing to the overall feeling of driving detachment and more like a nuclear washing machine than sports GT.....
