997 Turbo upgrade to 9e 28 by Nine Excellence (pic heavy)

[IMIA]

I've had my 997.1 turbo from new and after 8 years of ownership was faced with a choice to either buy a new 991 Turbo S or perhaps see if I could create (with the help of a top tuner) the 997 turbo S Porsche should have always given us with a Mezger engine and manual gearbox. After driving a 991 Turbo S for a weekend and Parr's Stage 3 RS Tuning demonstrator with 624 PS my car was actually all set to go to RS Tuning/Parr this winter. The 991 turbo was super quick but felt like a super fast limo compared to the Parr demonstrator and to me lacked any real driver involvement or character. This was also a criticism levelled at the 997.1 turbo.

I came across 9e who haven't been around for a long time and I'd heard lots of good things about. What I particularly liked about 9e was that I had direct access to senior staff and was not having to go through a distributor for RS Tuning should I develop any issues. A small nuance but its nice to speak directly to the developer of the packages themselves without having to wait for an answer from Germany where RS Tuning are based.

RS tuning Stage 3 kit consists of modded hybrid 997 turbos with variable vanes fixed in the open position and its a beautiful package but I was intrigued when Ken Napier mentioned for similar money he was offering hybrid GT2 turbos with motorsport bearings.The 993 and 996 turbo S (X 50) got trick GT2 turbos and I was disappointed Porsche in their infinite wisdom did not follow this recipe on the 997 instead choosing to get banzai performance from the new DFI engine combined with super quick PDK which again is a superb car and amazingly fast but lacks driver involvement (for me) with its PDK box.

I then saw this fellow's car on youtube at VMAX 200 last year which 9e had fettled.

https://www.youtube.com/channel/UC8OzfgpepQurB8QwS...

I took a risk and went with 9e rather than established Porsche tuner royalty and I have to say the 9e GT2 hybrid turbos really do change the character and give my turbo 25% more useable power everywhere. Power to weight ratio goes from circa 303 bhp/ton to well over 400+ bhp/ton. 0-300 kph reduced from 40 secs to VBOX tested 28 secs so translates into over 25% in real useable on the road performance. Over kill perhaps but I love it and its maybe how the car should have come as a turbo S from the factory.

Therefor decided to create my own take on how Porsches engineer may have executed a turbo S if they'd used the Mezger gen 1 turbo as a base.

Lighter wheels - Forged BBS F1



GT2 turbos



GT2 RS intercoolers

Europipe Sports Exhaust Stage 2 Loud with Emitec 100 CEL racing cats. Its a beautiful exhaust and a work of art. Shame its hidden and really does bring out the motorsport roots of the Mezger engine. Not loud like a 458, F type R or AMG 63 which all sound a bit fake but a real no nonsense motorsport flat six bark and good for track days with max 105 decibels at WOT which is under most tracks noise limits.




Larger throttle body, larger y pipe, performance air filter



H&R - 20 MM progressive lowering springs and GT2 rear anti roll bar results in zero understeer combined with wider 8.75 in and 12 inch wheels and trick Michelin Cup 2 tyres with increased tyre width size increased to 245 35 19 and 325 30 19.




GT2/3 short shift with alcantara shift and steering wheel. 1st to 2nd when cold can be bit stiff but it has rifle bolt action when warmed after 10 mins.



Before 9e



After

A big thanks to Ken at 9e and his team who were very patient explaining a myriad of questions I had as a newby before sending my car to them. The end result is breathtaking after 100 completely reliable laps at Bedford Autodrome demonstrated and the 997 turbo platform shrugs off the extra power my car has with no issues at all. The larger GT2 turbos love V Power so fuel consumption on average has fallen from 22mpg to about 18mpg. On track this fell to 8 mpg lol. Stock steel brakes can easily handle the extra power but wear rate is increased and the car was lovely on track in sport mode on the H&R progressive sports lowering springs with GT2 ant roll bars. On road the car remains comfortable but in sport mode on rough surfaces above 150 mph the suspension can lose composure. On smooth roads its beautiful all the way up to its new top speed of 205 mph.

9e 28



On the GT circuit at Bedford Autodrome it was easily as quick as a late 2013 MC were we were both pulling not far off 160mph on main straight! Stock car was at circa 140mph on the same straight so big difference although you don't feel the extra power on track as much as I thought you would. Seat of the pants for example I would have said a 991 Turbo S quicker but thats not the case according to 9e. We shall find out at a few VMAX events I plan to attend this year!

Not for everyone but if you have 997.1 or 996 turbo and are looking to liven it up you could do worse than send it to the boys at 9e. The 9e28 package is £20,995 + VAT. Factor in donor 997.1 turbo for £40k and for £65k you get a car which nothing this side of McLaren 650 S can touch. It eats 12 Cs and 458's for breakfast whilst still being a perfect pootler for the school run 4 up

We discussed this before I think ? It has to be wrong not just because it doesn't really make sense not to use the variable vanes (other than maybe keeping temps down) but it must be wrong because how would the boost be controlled since the VTGs don't have a wastegate they rely on the vane movements to deal with the boost

Did you get Carrillos on your new engine ? I hope so cos 0-300kph in 28s is a solid 600hp and that is in bending territory

I did ask but both RS Tuning/Parr and 9e assured me forged rods not required at this power level which is 624 PS and 650 PS respectively. My car only runs 1.1 bar of boost in normal mode and 1.3 bar in sport mode. RS Tuning/Parr will give you 680 PS on the stock engine with a 2 year warranty from Parr on the GT2 stage 4 package.

On the fixed vane point I'm just repeating what Lawrence at Parr told me who are RS Tunings agents here in the UK. May be have chat with Lawrence at Parr or Mr Schmirler himself?!

[IMIA]

Cheers guys thought I'd cover a couple of thousand miles in it before posting my thoughts. Just passed 70,000 miles and hope to do another at least another 200,000 miles in it. Absolutely brilliant sleeper as the car still looks virtually stock. I've had a bit of fun with a Huracan and GTR recently and to say they we're shocked is the understatement of the year



Still looks good to me after being my daily snotter for 8 years and I have no qualms about piling on the miles. It has stone chips all over it and I can leave it anywhere without fear of any unwanted attention.

[IMIA]

Thanks guys. Just a slight correction RS Tuning offer 660 PS on stock engine. Beautiful kit.

[IMIA]

Yes Toby I agree as you're probably aware I even managed to blow up my original engine when it was completely stock on a prolonged high speed run at approaching 170mph - thank God I had a warranty at the time and Porsche after a 5 month debate gave me a brand new factory fresh engine - in reality my new engine has only covered 9k miles

On 0-300kph times the 9e 28 its guaranteed to run less than 28 secs. On a good day in perfect conditions you could easily see 26.5 secs 0-300kph and on a less than perfect runway like Brunters you might only see 29.5 secs 0-300kph.

I wish I had a GT2 as its perfect for my current usage but they're becoming quite expensive and tricky to find. I have my eye on a very high spec 2009 car and hopefully if the owner ever sells it he will call me first!

If the rods do bend good excuse to then go the whole hog and upgrade to 9e 15 lol

Great write up! Sounds like a monster.

Whilst i appreciate the appeal is that you can add modification as when you have the cash, in the modern world of finance, i'd probably take the easy approach and go for a 997.2 Turbo S for pretty similar money all in. Did you consider that? Was it the mezger/manual combo that kept you loyal?

Thanks and yes I probably spent closer to £30k including wheels, rubber and sports exhaust so a 7 turbo S well within budget.

I'd say for 9/10 people the 7.2 turbo S a far more sensible route. Spent lots of time on both road and track in 997 and 991 turbo S and they're fabulous but PDK takes the shine away v.slightly for me.

Wow. Well done.
Thanks for sharing.

The alloys suit the car really well.

Get Ken to stick on some GiroDiscs/RS29s to improve stopping from both cold at VMax and hot on a track day. If you are running OEM drilled then they won't last long on track days given the power and weight of the car.

Enjoy!

Thanks matey. Yes when they wear out been thinking about these carbon brakes from Surface Transforms. When they're worn out they can be resurfaced. Not as light as OEM ceramics though.

Great write up - almost makes me want to go the same route; buy a 997 turbo and head straight to 9e, they sound fantastic

Its a v.good package but I think their best daily driver package is 9e 25. Think its a lot more money but when Porsche were originally refusing to give me a new engine when my old one blew up I was all set to go for a 9e 25 with circa 700- 800bhp.

If you can find a 997.1 turbo or 996 turbo for pennies with a blown engine or very high miles then I'd go for a 9e 25 as a dd. Superb cars.

Well, might as well go 9e20/17 at that expense

More noisy fuel system, upgraded gearbox, best to remove front diff, competition clutch - not really a car you can use all the time like the 9e 25 but yes as a VMAX contender may as well go the whole hog and get a 9e15 lol

Love the wheels... car looks great !

Huracan has been timed to 300kmh at 27.6s..... when you can take a second out of a GT2RS whilst weighing a couple hundred kgs more you have some perspective about how quick a car it is !

All that said, I'm surprised you didn't love the 991turboS if you were looking for the ultimate daily - best car I've driven without doubt & prefer it to the Huracan (whose most amazing characteristic I think is its chassis, as its gearbox/4wd system is at least on a par with the 991).

Hi Zero

I love the 991 turbo S and H too but far too much modern tech and the cars virtually drive themselves with auto boxes. You get bored after a few days (well I did) as there's virtually zero driver input required. You do tend to look out of the window at bewilderment how quick the 991 turbo S is across country but inside the car you feel as though you're doing 50 mph instead of 150 mph in complete comfort and a latte in one hand to boot!

In the 9e 28 when cold you have to avoid 1st to 2nd for 5-10 mins or so, not hit the loud pedal in the wet and even when its bone dry wait until the tyres are warmed up. You also have to straighten the 9e 28 out properly before getting on the power like a fast bike or the tail wags. The LWFW chunters away, the sports exhaust whistles and barks as you potter down the road, and the whole package literally makes the 997 turbo come alive. Honestly very happy with her indeed.

Have a look in the youtube vid in my original post what the 9e 28 did to a 991 turbo S and other cars like 991 GT3, LP 560, GT40 lol at VMAX quicksilver. The 9e 28 also registers a GPS verified 201.5 mph at the same event and conventional wisdom says in the absence of tailwinds its very difficult to break 200mph at Brunters without a real 720bhp. 9e 28 also probably has circa 600 + lb-ft torque which gives it a noticeable advantage over the new turbo and the H mid range.

Some other tuners have a swipe at 9e for underquoting hp figures but Ken insist unlike other VTG tuners packages his is the only package that gets faster and faster all the way to VMAX and holds its power without pulling timing like other tuner's VTG packages.

Even if the 9e 28 was slower than the newer cars its so much more tactile. As another poster hinted at its very difficult to use the extra power on road without being anti social as other cars simply do not expect you to be able to warp past them at the rate this thing flys at with its snails lit up. I'd love it if a journo would independently test a 9e 28 back to back with a H and 991 turbo S. I suspect Ken at 9e would be selling a lot of 9e 28 packages after that test!

If PCCB's will last 160k miles worth of road use (and they can), the ST discs will do 250k miles. Maybe not as light as the OE PCCB's , but only a bit heavier (and waaaay lighter than any steel discs

Edited by Slippydiff on Saturday 31st January 23:54

Thanks Henry. How's peddle feel? Also are they as easy to modulate as OEM steels i.e. not grabby on / off?

[IMIA]

Good idea may well do that! It would make an interesting read to see it independently vboxed.

Vid and results from VMAX 200 by EVO mag. 9e do rather well and the 9e 28 comes 7th overall against some pretty rapid cars.

I did and the vanes are not fixed.

Mr RS should defo have a word with his UK agent Parr Motorsport. Lawrence at Parrs own words were, "RS tuning modify your OEM turbos and fix vanes in fully open position. Result is not as wide power band but when you're in the zone above 3-4000 rpm they really come into their own and the car is more urgent." Their demo car was a peach but God knows what he was talking about re fixing the variable vanes as he sounded pretty convincing - maybe Mr RS does not want to give his trade secrets away or may be they reprogramme the vanes to stay open for more time? Who knows? Ken Napier will not tell me how they've managed to find a solution to their VTGS pulling timing lol (a problem they struggled with for 6-7 years with VTGS which initially put me off tuning my VTGS) so these guys do all keep trade R&D secrets to themselves! As I mentioned earlier in this thread I was all set to go with Parr but the allure of the GT2 turbos was too hard to resist. 9e were also a bit more flexible. By way of example RS Tuning did not want me to use a Europipe 100 cel stage 2 exhaust with their package as they'd not tested it (totally understandable but I felt I was getting an inferior exhaust with their Cargraphic 200 cel exhaust which was all that was on offer with their 997.1 stage 4 kit). Something may have got lost in the translation on both the VTG turbos and exhaust as later after I'd sent the car to 9e instead Parr did say they would have worked something out on the Europipe exhaust. Hopefully see you and your beasty at VMAX on 7th March?

Yep I have them on my 997 GT2 M600 - had first outing at Silverstone with Mike Wilds on Sunday 1st and they are brilliant. Best brakes I have ever had on any car I have owned. Have few more days out on track at end of month and then Spa in March (all days running on slicks if dryish) so will let you know how we get on but I suspect faultless performance.

Thanks David. Can you keep us updated?

As an aside how's your GT2 compared to your old GT3 RS?!

TB993tt said:

I've been trying to hint to you in previous posts that much of what "tuners" tell you should be taken with a pinch of salt, for many years snake oil has been well and truly force fed into us poor punters.

Firstly Parr Motorsport are NOT and never have been an "agent" for RS Tuning. Parr's relationship was with Cargraphic. The Cargraphic car whose pic is on their website had two versions of engine tune both with working VTGs. The original tune was 624PS/826NM standard internals but Secan intercoolers to allow the high power reliably (in terms of maintaining the power through IAT control). The second rebuild had different pistons and Carillos and was around 680PS/900NM, this was the engine which propelled that 1519kg car (in the pic) from 0-200 in 9.1s and 0-300 in 23.8s (in the Sport Auto test). RS Tuning have not built any other engines for CG since then in fact I understand they don't speak much now.

So you thinking that you may have been "considering" an RS Tuning build is wide of the mark, like I said many "tuners" feed you "stuff". You say above that RS Tuning wanted you to use the CG 200 cell exhaust ? I can tell you that RS do not use 200 cell cats, they only use 100 cell Motorsport (expensive) HJS cats. My guess is that if you had gone with Parr you would have got a kit put together by CG with a program from either Parr or CG's new program supplier, sure they all like to say it is from RS but whilst it may be similar and I'm sure CG know a lot of RS's suppliers it ain't the same as RS want premium prices for their proprietary components.

Lastly Ken did not struggle with VTGs pulling timing for 6-7 years because I don't think Ken even owned a Porsche 7 years ago and 9E didn't exist until 4 years ago

Sorry should hav said 4-5 years re 9e. I've been aware of the issues since your monster VTG thread. Re Parr I'm disappointed if you're right as they never mentioned CG just RS. There was a discussion with them about inter coolers and exhaust and they always mentioned RS. I'd have been suing them if you are correct so pleased I went with 9e. Sorry newby to this modding scene so did not pick up the hint lol!

Sure will update thoughts when they enter mind..
The GT2 is now set up with exactly same suspension, wheels, gearshift, steering, wheels & slicks as the GT3RS plus has 150bhp more so great fun as you can imagine.
Just can't wait for Spa next month. Have fitted it with 4 camera system and data logger and in next month or so will post a load of videos on line of Mr Wilds doing his stuff around all the best tracks in UK and Europe. Should help us all keep on the black stuff:-)

Look forward to the vids - sounds like a monster!

Actually my friend longer in Porsche ownership.

9e is 4 years old and we celebrated in testing by running over 370kph for several minutes with a top speed in excess of 403kph (250mph) in private testing recently. Just don't expect us to 500kph to celebrate when we reach 5 years

Getting tantalisingly close to the world production car record maestro - be good to see a British flag and 9e at the top of the list



The Hennessey Venom GT hit 270.49mph at the Kennedy Space Center on February 14th, thus becoming the fastest production car in the world by beating the Bugatti Veyron Super Sport's previous record of 269.86 mph.

Hi Toby, been doing a bit of research on Parr and whilst I accept they may not be RS Tuning agents I'm pretty sure they have a good relationship with RS Tuning. Firstly their car which I drove is brilliant. http://www.parr-uk.co.uk/Parr%20997%20Turbo%20feat...

Also there was a long discussion about intercoolers and which exhaust I would use over a period of 6 months. The guys at Parr specifically said they would have to check with RS Tuning on the intercoolers and exhaust not Cargraphic as their software had not been tested with those bits of hardware so they would not be able to then guarantee the 624 ps stage 4 package.

Parr runs Carrera Cup GB and one of their drivers is doing pretty well in Pro Am 2:

I can't see guys with this sort of pedigree pulling the wool over their customers eyes. In fact I'd have more faith in Parr or 9e for that matter than I would an OPC in terms of looking after my car moving forward. I hadn't appreciated Parr has been around as a Porsche Motorsport specialist for 30 + years.

I don't know Parr and from what you say they do seem a decent outfit. I was pointing out that Parr will deal with RS through CG, RS have only "built" two engines for CG and haven't actually done anything with CG for a few years since they appeared to stop talking -for reasons unkown but CG went through a fair transition with the Schnarr brothers splitting the company.
This silver car in your link has a Cargraphic engine build from what I can see, 200 cell HD cats (like I said before RS only use 100 cell Motorsport), carbon air pipe (RS don't use these), larger throttle body - RS tested these and doesn't use them at this level of tune, and most tellingly it states it has larger intercoolers yet the price for the kit is £20K ? The price from CG when RS developed this kit was 47592 Euro + MwSt and in late 2013 that would have been £48K !!! this is with the ridiculously expensive intercoolers and we (Parr included by the looks) know RS would not sell the kit without their coolers.
Doesn't quite add up does it.

On the intercoolers they switched from Secan to some fellow in France who I get the impression is not around anymore. Without Secan coolers £20k + vat is about right when you look at current exchange rates of 1.3 Euros to the £1.

With Secans it would be £36k + VAT ish less the cost of the GT2 RS coolers. Remember 997 turbo/GT2 is now a very old platform so I can understand why the Likes of CG etc have moved onto tuning 991/Cayman/Boxster/Cayenne etc. All those carbon bits and throttle bodies etc are CG bits available on their website. RS Tuning do the bulk of the work i.e. provide the software and modify the turbos on CG's packages or they did. As you're aware obviously same on engine build where RS Tuning carry out the builds. I don't thing the bulk of CGs work would be based on engine builds. Cg's in the business of selling maps and exhausts mostly - thats their bread and butter so it doesn't surprise me that only two cars were prepared by RS Tuning for them.

I reckon the 624 PS car CG were touting around various tests was really built 680 PS car.

https://www.youtube.com/watch?v=xMnPzRYiqbk

The Parr car I drove basically has the same engine as above youtube clip and whilst its not got all the carbon fibre lightening by 150kgs its certainly not as good or fast as the CG car in the clip. You can't have what I'd describe as a really fast car without building the engine - no chance.
