Akrapovič dB reducer for the GT3 is nice

 
 

Radio ? NONE.

Very elegant solution D - but it won't come cheap since you have to buy the Akrapovič exhaust system too..!
 
If true, 2-3dB is a decent reduction in sound pressure level ( -3dB is equivalent to halving the SPL) but note the caveats in the blurb (* and **).

I am going for the Ti by pass pipe any way, more BHP and torque and 9lbs lighter out back.

David,
 
You want more bhp and torque from your GT3? Ye Gods!
 
Or is it the noise regs that has driven you to this decision?
 
9llbs lighter out the back will hardly be noticed with 500bhp pushing the beast along.
 
Enjoy!

yes the cars very quite sub 6k imo  the advantage is more power lol
 
At least the exhaust is switcable , unlike all new cars which this is now banned !!!

A few more snippets from Rennlist and PH, make of them what you will  
 
* The car was "driven across the stage" at a meeting recently.  Somewhere US based I think?
* No PDK, manual only
* 420bhp naturally aspirated flat six, brand new engine not used anywhere else (yet)
* Spyder and GT4 will be identical, bar the roof
* The GPF particulate filter zaps lots of power, so to get the 420bhp has taken more than a few minor tweaks
* There will be no switchable exhaust - one setting only
* To meet EU noise regulations the car will be a LOT quieter than the 981

Re: Cayman 987 Gen1 & 2 2018/07/16 11:02:33 (permalink)
Nothing definite to report but the latest rumour mill has it that the 4.0-litre is a "new" engine, not just an enlarged 3.8-litre, will have 420PS, a particulate filter, no switchable exhaust and there'll be no PDK option. Nothing new there then bearing in mind the latest well-publicised emissions and external noise regulations.
 
There are the usual rumblings/complaints that the engine will be strangled and that it won't sound as good as the Gen1 GT4. Pie in the sky in my opinion - it's the combination of intake and exhaust sounds inside the car which is important (especially for a coupé), a fact which won't have been overlooked by the development team; and besides, the 3.8-litre was strangled by DME/throttle tuning to suit marketing requirements.
 
The word is that the Spyder will be a soft top GT4, which would seem to be unlikely to me unless the GT4 chassis has been dumbed down significantly, i.e no GT3 front suspension components this time. Preuninger’s group are responsible for GT car development whereas, as far as I know, the Spyder remit comes under the general development team, so there's scope for differences between the two cars provided the bean counters haven't been at work.

Re: Cayman 987 Gen1 & 2 2018/07/16 11:17:18 (permalink)
Indeed!  
 
I differ in my view of the engine, as you will have seen on PH.  I'm not a fan of the 981 GT4 power plant, nor do I like the spec of the new one.  I'm 99% sure I won't be chasing a 718 GT4 allocation and I'll be sticking with my 981 CGTS.  I also think the GT4 and Spyder WILL be identical to keep development costs down and maximise profit per unit.
 
Can't be too long to wait and find out for sure now I don't think, the car must be pretty much ready to go.  Probably just awaiting WLTP and RDE testing.

I guess the source is Frank Walliser who is quite a chatty (within limits) guy and much more credible than AP.
 
The key will be how it drives.

The word is that the Spyder will be a soft top GT4, which would seem to be unlikely to me unless the GT4 chassis has been dumbed down significantly, i.e no GT3 front suspension components this time.




my 1st thought also was the new GT4 might not have any adjustments when I read that.

I cannot see the Spyder having full adjustable sus all round and track tyres,  so the rumor is either **** or the GT4 will have a base chassis !

the new engine is also odd for a small run so I expect this new 4.0 unit to be in a drivers spec 992 very soon with 450BHp  992T Nasp manual ;-)
 
last of an era. for me it's very hard to pick cars as some tech is **** and needs progress and some tech is well .......just dull.
 
all 981 and 991.1 are in the 1st section for me, new tech which was not great ie EPS is rank in all 981 and 991.1 for me enough to never own either.
 
hence the Cayman R was "last of an era" and the newer cars tech ruins the drive,  imo of course but cars felt very unsports car like :-( great cars but not for me.
 
With the next run of cars they have at last nailed EPS, the GT3 991.2 EPS is just about perfect, so some times new tech can work it just takes 4 or 5 attempts to hone it. bit like PDK, 987 PDK is pretty crap all told, 981 and  991.2, 718  PDK is really a step forward.

Now we are stuck with regs, so petrol BHP sapping filters and non switchable exhausts !!!  new GT4 sound clips are poor imo
 
one of the best sounding cars was the gen 1 GT4, better than my GT3 in fact, hence the by pass pipe mine will have and will pass an MOT ;-)
going forward, YOU CANNOT fit after market exhaust and pass a MOT !!! or a button exhaust !!!
 
So the 991.2 GT3 nailed the EPS tech and avoided the EU regs,  last of an era car just like the Cayman R was.
 
Tough times for drivers cars, my fear with the new GT3 was EPS  so that was such a bonus to have great steering, but every thing seems to have come together on that car.
 
987.2 PDK feel dated, 981's feel dumbed down with EPS
 
GT4 gen 1 will be the modders drivers car imo ,, the Gen 2 will be tied into EU regs and MOT laws, so you better like it oem.(it might nail it who knows)
 
I know I own it so it's hard not to come across bias, but I hope by now after owning a older GT3 and GT4 and both Spyders, plus buying back a 2nd R that every one here knows I don't care what is said about cars, even when I own them I give 100% honest reviews and point out all the down sides straight away on my own cars.
 
I am still blown away by the 991.2 Manual GT3, the engine is the best thing I have ever driven engine wise, the EPS is nailed, the infotainment is at last current !!! Porsche really do have infotainment issues even the GT4 was dated.
 
The GT3 is predictable at the limit and over it,  GT4 was tricky at the limit or over it due to missing that multilink rear and changing cambers under loads.
 
I really cannot afford to keep my GT3 (I do cry at night about it)  and I am trying to sell every thing to fund it, because they have nailed the 991.2 Manual GT3 in every respect imo, it's wonderfull thing.  unlike all past GT3 where you needed the right road at the right time to get the best from it, the new car just works on normal roads and excels on track.  the 991.1 GT3 imo was a bit of a odd car, gen 1 EPS again and no manual might see those cars plumit in price, esp after the 10 year engine warranty runs out in a few years time.
 
992 GT3 is going to be hit with EU regs filters, exhausts and god knows what by then.
 
strange times for "drivers cars"

This is a GT4 thread, not a GT3 thread    It should be a better car, it was almost twice the price/£50k more expensive  
 
Not sure where you're getting your MOT test information from, there's nothing added in the May 2018 changes that would back up what you're claiming.  Do you have a source?
 
Horses for courses, but for me the 9x7 (bit more raw) and 9x1 (bit more civilised) cars both have their merits depending on your personal needs.  I think we're at the turning point now though regarding emissions, hybrids, noise etc.  Things are going to change rapidly from hereon in.

Of the several things I do not understand about the Gen 2, is the power rating 'story'
 
If the Clubsport is 420-430 (hp/PS whatever) and this is achieved without a GPF and the engine is the same as the road car because of homologation requirements, why do we thing the road car power with a GPF will be 420-430?

Doesn't GT4 racing have BoP rules?  I'm assuming they come into play with air restrictors etc.
 
I've only heard about road car power levels, not the CS car.

All the info so far is about the Clubsport; the Canadian guy, the Manthey briefing. My friend who went to the latter said nothing was said about the road car because it is still not finalised.
 
On BoP, everything published would suggest Mercedes et al performance will be managed down, rather than that of Porsche.

Whoopsy's info on Rennlist was road car - manual only, same spec GT4 vs Spyder, 420bhp - as was Fokker's on PH.  Their info matched each other.

true it should be better I guess, but that means to get every thing right you need a £130k car in Porsche land, every thing under it will be a cost cutting or compromise and people will again moan about it not having a GT engine or being a true GT car even though it will still be class leading in that sector.
 
I thought the GT4 was going to be my dream car and it fell short, the new one will also at this price point, how can it not when to get every thing right costs £50k more !  just lets hope it can improve in key area's over the old one.
 
the 997 = a bit more raw, is correct, but it's not usable raw and more a pain In the arse over raw,  single mass flywheels, heavy clutches and sus which just cannot cope on todays UK B roads one bit, gen 1 PSAM units= a fail imo . so zero merits  if you want to drive it and not store it like most are !  3 RS come to market in the last week with 1k miles on them ! pointless, raw is nice if you can use it ok imo the older GT3 were never B road cars.
I love them but don't want to drive them in the week.
 
I agree though,  emissions, hybrids, noise etc it looks the end of true sports cars and going forward you might as well buy older or go electric, every thing in the middle will be throttled/ruined or be less exciting.  who wants to **** about with even more filters,  as for ad-blue and all that hassle thank goodness I have never owned a oil burner ! 
 
Lotus have taken out the switchable exhausts so have BMW,  the Golf R 's slower than the last one and so it's started for the end of petrol fun in new cars !!!
 
I think the current GT3 is the pinnacle of what can now be done old school wise in the old regs, be interesting to see how they cope on the new GT4 and 992 GT3 under the new strict ones.
The noise is def gone in the new cars, and if they replace that with farts well you can stick it.

Performance = cost. If we are looking for a car that fulfills our dreams can we afford it? Even a small increase in power output costs. And when we have gone to the next stage will we be satisfied?  As for emissions in the future these will be the big issue. We shall still seek more power from the battery driven motor vehicle and that power output will probably have a big effect on mileage. And then you return to the hamster wheel of performance = cost.

Who knows what the Canadian crossword-puzzler was referring to, lots of assumptions. When I spoke with FW he was clear on the Clubsport not the road car but, as they still have final testing, certification etc who knows - for sure we don't. The Manthey VLN session was Clubsport only. So unless SRO regs are going to change to require OEM exhaust in its entirety, I for one am quite comfortable being uncertain.
