Okay. Thanks

I believe the R8 redline is 8600rpm and 4RS is 9000rpm. Are you saying the induction noise from R8 is better than that of 4RS. Because one of the main attractions of 4RS is having a 9000rpm mid-engine. One of the main reasons to prefer it to say 991.2 or 992GT3.
Try and get a drive in a 4RS and what Mr Bigmowley says will all make sense....... thumbup

I find it hard to understand the preoccupation with 9000rpm .... surely what is important in creating the performance and character of the car is the shape and breadth of the torque curve ?

It must also be said that sound is very subjective ... inside or outside the car ... and true altruism if better outside ? Maybe not ...

What amazes me is how the engineers who did all the calibration work signed it off.

Please pardon me for further queries. You said R8 V10 is a masterpiece but the sound is muted inside ‘but nicer’. So how could you conclude the sound is nicer when it is more muted (hardly hearing it?) That means the exhaust sounds are mainly enjoyable when the windows are down or mainly enjoyed by the passers-by?

Also what makes R8 V10 a masterpiece? In what way is it better than GT flat 6 engine found in 991.2 or 992 GT3. I believe the engines in these pull to 8800rpm.

Simply speaking would yourself or other take R8 V10 over 991.2 or 992 GT3?
OK so here we go.
In the RS you are not listening to the engine noise, what you hear is induction noise, it’s the air rushing into the engine through the side vents which are just about at ear level. That noise does alter as you go through the rev range and as you open and close the throttle. Trust me it’s not a particularly nice noise, it more of a white noise like a badly tuned radio, it’s also incredibly and overbearingly loud at full throttle. The only time you can hear the engine over the induction noise is that brief window above 8500 when the valve train makes a noise like a death rattle. Anybody with a shred of mechanical sympathy will grab a gear at that point. Check this out at 26 secs in. That is not me hitting the limiter that is me changing up right at the point the valve train joins the noise party. There is probably 400 revs or so left at that point but you gain nothing by using it.

https://youtu.be/og-AkbmFqQs?si=C4ikAFTE18yEaUQT

To be fair on track the noise is actually a positive feature. With a helmet on it’s an immersive part of driving what is a fantastic track car. It’s very close to what a proper GT racing car sounds like when it’s shorn of all the sound proofing etc. Assuming that is what Porsche were trying to achieve then it’s a win. It’s a totally different sound to any other Porsche GT product I have owned or tracked (apart from the valve train noise “they all do that sir”). You can totally forget listening to the lovely flat 6 engine noise that is characteristic of the brand in general, trust me you cannot hear anything in a 4RS but intake noise.

However on the road, which lets face it is where the car will spend the vast amount of its time it’s terrible. As I said great for impressing people, awful to live with. I drove the car to Spa and back an pretty much hated every minute of it. I actually drove slower than normal as on very light throttle openings, up to about 80MPH you can keep it just about OK. At one point I noticed that the radio volume setting was right at the very top and I could still barely hear it over the background noise.

As far as why is the V10 a masterpiece. Do I really need to wax on about it here? If you don’t get it then you probably never will. It’s another step up from the Porsche flat 6, which whilst it is a great engine in its own right it is second best in this comparison. Just stand on the pit wall when I go past at full chat it’s simply bloody glorious.

I believe there is a bandwagon effect going on. Bigmowley prior to selling his RS4 posted the below in this same thread on Friday 21 July;

‘’No shortage of GT4 RS at Oulton Park today. Six different cars on track, usually a few out together. Fantastic car incredibly close to a race car to drive. Brilliant in the tight stuff, the direction changes are amazing, car rotates beautifully, so nimble. It feels unburstable, just soaks it all up. Could do with a bit more power TBH. I fitted RSL29 pads which take a lap or two to warm up but after that just immense with no fade or durability issues at all. Feels like it could do a six hour race straight out of the box.
It's no quicker than my R8 over a single lap but the R8 just falls appart after a few laps with brakes and tyres throwing the towel in and the RS serenely driving off into the distance.
It's that good it's a bit boring laugh’’

Suddenly after he sold the 4RS for a profit after putting 4000 miles on it (I would probably do the same if I had the choice between selling 2 cars for profit or loss), the 4RS is no longer that good and the R8 he earlier described as falling apart is now so much wonderful.

I remember that CaymanRS23 criticising Bigmowley for describing 4RS as ‘close to a race car’ and CaymanRS23 giving a much more objective assessment of GT4RS

So to me, the latest review by Bigmowley is likely affected subconsciously by justification for selling the 4RS. It is unbelievable for a man of his wealth and experience that his objective assessment of a car would have done a 180 degree turn within 4 months.

I am relatively new to Porsche ownership and probably not as rich as a lot of people here and I am not in the market yet for 4RS or GT3 (would be in the future ) but the way R8 was being described and the current price points is beginning to make me think, I could just add R8 V10 to my 718 GT4 rather than replacing the GT4 with GT3 or GT4RS

However, I just don’t want to base my opinion on one review, especially the one that to me has shifted dramatically.

We need more opinions from those that are currently driving 4RS

Thanks for sharing your review. Really great read.
I called it then! I said at the start, when the reviews came out, that the noise would be a 5 minute wonder and eventually a painful annoyance.

There are a dozen for sale on AT for some time now and nothing seems to be moving with them. The buzz has worn off the ears and the appetite for them.
I don't think history will be kind to the model.



Hang on Julian you are being very unfair there. It’s still a bloody brilliant car in the right situation. It depends on what you want from a car. Some people (presumably the hard of hearing smile ) will love it. The rawness and demands it makes of you are so different from almost anything else that’s out there. There will be a hardcore of people for whom this is the best thing ever. They probably own a Caterham 7 and a wingsuit.
Assuming that Porsche don’t over supply the car then I think it will be a niche choice for years to come.
It’s not a £150K car though in my opinion. It doesn’t have the breadth of capability that the price demands. I chose to keep the R8 over the RS in the end because the R8 is as much fun on track but about one million times better on the road.
My spidery tingling must buy a car urge is nudging me towards a Huracan Technica. It’s basically my R8 less 100Kgs and with another 25bhp . Must resist, must resist, must resist………………………..boxedin

Oh that’s unfair. I haven’t done a 180 degree turn at all. The 4RS is a bloody good track car, so is my R8. The R8 is not a standard car remember. The stock R8 when I got it was poor on track, but it didn’t take long to sort it out.
At the current price point the R8 RWS is on a par with a well specified GT4. Personally it’s an absolute no brainer the R8 is a way better car for the money, different league. The benefit of any Porsche GT product is that it’s track ready straight out of the box ( well geometry and pads first) that is not true for the R8. However do not for one second underestimate the depth of engineering in an R8 it’s every bit as good as a Porsche and in some ways better.

As far as “close to a race car” I absolutely 100% stand by that comment.

Ps I am definitely not wealthy, I keep spunking it all on bloody cars.

PS can I respectfully point you in the direction of LMS GT4 racing, You will find the R8 has considerably more success there than the Cayman GT4.

great write up mister Big, such RWS R8 the one you have looks low, how is such over speedbumps and so on... or do you have a lift option, I don't like such extra things on a car, but handy for bumps I guess.

btw, a R8 GT seems about 100kg lighter then a normal R8 V10, although a RWS has lose some weight to I guess?
You are quite right it is very very low. The front splitter is an Audisport part and is a lovely high gloss carbon fibre. Which is almost always cracked. I’ve had it repaired twice already. banghead
I had nose lift on the RS and it was brilliant. Not available on the Motorsport coilovers on the R8 unfortunately.
My R8 on the corner weight scales is 1550Kgs with half a tank of fuel and no driver. I think it’s about 100Kgs heavier than the 4RS. One of my winter jobs is to see if I can get a bit of weight out of the R8 without spoiling it.

Sorry if it's said before in another thread - is that R8 a standard RWS car? You haven't started to further
mess around to remove weight yet etc to get that 1550kg with half fuel.....?

I’ve been out in my mates 4RS a couple of times now and I was actually surprised how civilised it was! The noise from the intake is loud at 7.5-9k rpm for sure (it sounds like you’re sat in the airbox of an old V6 Formula Renault 3.5) but you’re only ever up there on the road a couple of times a drive (unless you like to boost around at triple digit speeds on the road constantly). I actually really liked that aspect of it, and even the ride on a motorway is pretty civilised. Not noticeably worse than my 981 GT4 was.

My biggest criticism of the 98X platform has always been the rear geometry, and that hadn’t changed. The RS definitely improves things as it’s got a more stable (read stiffer) dynamic setup, but there are still rear end stability issues. My biggest criticisms of my 981 were largely resolved by tyres. The later N1 Cups are a lot more progressive in breakaway, so although the rear end still moves a lot and rolls into oversteer, it does so in a more controllable way which means you can at least have some confidence in the car. It’s not surprising though that so many AM drivers in GT4 series who run the Clubsport have shunts where they put it in the barrier as a result of over correction…basically the video above at Brands but on slicks.

For me, the car makes absolute sense at £160k. Less so at £250k. But then that’s a moot point as so few can actually get one at list that it ceases to be a £160k car and at that point I’d struggle to look past a 991.2 RS.

Fairly standard really. In terms of weight out I have replaced the standard seats with some much lighter buckets, but put back a bespoke harness bar and harnesses. The Audisport parts will be similar to the standard parts, a bit lighter maybe. Its on the optional forged 20" Audi alloys and Cup 2 tyres so a bit out there maybe. The AP brakes are a bit heavier than the standard units as they are bigger.
I have several pictures of it on the corner weight scales somewhere but I will need to dig about to find them. Not sure if you think its heavy or light?
Personally I think its bloody heavy for an almost all aluminium car.

A Mate who has one ( had drive with him and agree too much induction noise ) always looks at the up side , no phone calls can be taken in the car , as impossible to hear anything , so no hearing from work or the wife to ruin a drive to a track day .

Hm.... it's normal i think for that kind of car. Probably a little on the heavy side given you have much lighter buckets installed. It's broadly in line with a V8 mid engine Ferrari though. A McLaren would be a bit (80kg perhaps) lighter but that's more or less the expected weight. My old R8 V10 was well over 1600kg fully fuelled iirc but obviously had no bucket seats and 4wd.

What a great post thumbup
It’s clear to all on here that you’re very adept behind the wheel. Which UK circuits have you driven your GT4 on this year ?
I wonder do you have any more UK track day outings planned for what’s left of the year ?
Do let us know, I’m Midlands based and more than happy to travel, as it’d be great to see you in action and get an insight as to what kind of lap times you’re capable of in the GT4.

Oh, and for FWIW, I don’t see anything resembling a Volte face in Big Mowley’s comments on the 4RS, on the contrary, I’d say he’s been completely consistent

Thanks Bigmoyley.

Please pardon me. I just don’t believe there are no additional financial reasons for selling the 4RS instead of the R8

Are there other individuals that have both (R8 and 4RS) that can provide their own insights in addition

Thanks
Fortunate enough to have had both V8 and V10 in both manual and s-tronic as well a 4RS. Had R8 when they first arrived in 2007 have driven a number of them over the years.

99% of my time in them has been on road, but as much I love the R8, i'd go for 4RS.

Whilst I understand the issue bigmowley has with the 4RS in terms of ride, they are different cars, with different aims imo. The R8 is for me a grand touring sports car whereas the 4RS is track focused sports car. Yes with the rubbish roads the ride of the 4RS can be a bit uncomforable at times and as bigmowley said it bounces around and wheelspins on the worst of roads, but on the right stretch of road it is magical.

The sound it makes for me hasnt been an issue at all. In fact i think it sounds amazing. Most of the time driving around the sound is not that much louder than the V10, it only when heading over 7.5K it becomes noticeably louder. Yes the sound at 8.5k+ can become a bit too much if you are flying around at top speed all day but that seldom happens.

I had been lucky enough to run a Sport Classic along side 4RS, until the 4RS had to go, but i found myself reaching for the 4RS keys most of time. The SC is probably a more comparable to R8.

Ultimately there is no right or wrong answer. You have to try these cars and as we are all different what works for one person may not work for another!

Agree with this. I think modern cars have encouraged us all to become a bit soft. I just sold my 4RS but only because the Spyder RS is coming fairly soon. I am looking forward to the slightly softer ride making it a better road car, but hoping the magical induction sounds right behind your head are just as intoxicating.

Except that I would rather keep my very modified 981 GT4 than add £100k to this in order to step into a GT4RS that Porsche do not want to sell me.

But maybe that has become a self-fulfilling prophecy ?

Thanks rkwm1 for your opinions and for reading my post as I intended it to be.

I also thank Bigmowley for his measured and educated response to my post. You are actually making it more likely that R8 would be next car rather Porsche Flat6 engines

Well for Slippydiff throwing cheap insults, that is your problem and Cossers cashing in, I am not surprised, he has the habit of stalking me on the forum.

The data from fastestlap.com as in the below would also support that 4RS is faster than R8 on tracks and in straight lines.
