Kits 2,3 are modified VTG exclusive to RS - no one else has access to these.
The Cargrahic 997tt RSC 3.8 is being fitted with kit 3 as this is being typed and will be at the Essen Motorshow this week end.
Kit 4 is non VTG turbos.

Any enquiries for these kits should be directed to Cargraphic and their distributors - emails to RS will very likely bare no response.

That kit 3 is going to be mind blowing, can't wait to see the test of the Cargraphic RSC 3.8
I would think the modified VTGs will be at their limit at 618hp - I am specualting that it is only the compressors which have been worked on so the hot side will have a thermal limit which has probably been explored. Pricing for kits 1 to 3 is to be announced after the Essen show - apart from the exorbitant cost of the turbos it may actually be "quite" good value -relatively Kit 4 will undoubtably be the K24/26 race turbos and is available for the 996tt also.

I am running a classic Schmirler power curve with 640NM by 3050rpm and peak power at 6410rpm which combined with 1390kg and 2WD makes for a very satisfying package, 100-200kph in 6.15s
I am obviously drawn to the new 997tt and GT2 and enjoying all the threads however I feel the weight is always going to blunt the performance, particularly under 200kph which tends to be where I spend a lot of the time.
Can you give me a linky to that Ruf VM6 vid ?
cheers

The Ruf V M6 is not surprising considering the weight of the M6 and the lower end torque of the 993tt. At a recent similar airfield session it was apparent that the tuned 993tts were quicker accelerating as most other stuff out
there - here is a crap video of my car running 520hp against a CGT2 up to about 140mph:

The stage 4 kit may become obsolete compared to the overall performance of the VTG kits - I guess there will always be some who need the most peak hp ?
I think it would be a very big technical step up to make completely new VTGs with bigger hot side - this is where the real clever stuff comes into play and where the big manufacturer investment needs to be done - it may not happen.

That being said, the Stage 3 should be fast enough as it is for just about anyone (23 seconds to 300 km/h).

With just 618hp My guess would be around 30s

P.S.: all 600hp cars are around 30s, the Enzo with 660hp did a 26s

Markus, the Turbos are extremely capable due to their flat torque curve.

On the other hand, you have warranty .

Yes, gotta agree on that. However, I'd trust Alzen and RS-Tuning enough to believe their claims. After all, the Ruf Rturbo 550 cars have already been doing 0-300 km/h in under 30 seconds for years, so a car with 70 extra bhp should have no problem doing it faster. Why so much faster than the 599? No clue. But honestly, I doubt you'll be complaining any time soon with 620 bhp under the hood .

I heard that 9ff actually had their own made by Borg Warner (for the 660 bhp kit). Wouldn't touch their stuff with a stick, but those turbochargers might be interesting to look at.

Is Uwe Alzen is the source for your 0-300 figure?

P.S.: The benchmark is not so much the 599 but the Enzo. I cannot believe that the 997TT with 618hp should be 3s faster than the 40hp stronger Enzo...

These are the claims by Alzen for the 996tt with 626hp kit and much less torque:
http://www.juergen-alzen-motorsport.de/unternehmen/html/rs_kit_5_basis_420_ps.html
If these are correct then a 618hp 997tt is going to be sub ~25s 0-300kph ?
Time will tell, it won't be long before the Cargraphic 997tt RSC 3.8 is under the stopwatch

It would have been if Porsche hadn't limited it to 480 peak HP and 680Nm peak torque.

Interesting, thanks

P.S.: Not too credible anyhow, just compare the Alzen claims to the Enzo performance. I guess, somehow they have to sell their cars...

Markus, looking at the Enzo and similar cars, they have much more drag than "normal" sports cars. I'm sure it could do it in close to 20 seconds if it had a smooth body. Honestly though, I doubt anyone here will be a customer for this kit (although I can think of at least one pharmacist ), so the point is really quite moot.

Still not convinced: remember the post summarizing some statements by G. Schmirler some week or so ago. According to this post the 540hp GT2 is still slower than the Carrara GT (which would shed some unfavorable light on the sportauto test results of this car...). Thus, you need more than 540hp in a GT2 (no AWD!) to compete with the Carrera GT. Now add the (negative) AWD effect. On this basis a TT with 618hp cannot be much faster than 30s...

P.S.: I probably would have believed in a sub 25s 0-300 performance for a 620hp RS version a year ago as well. However, over the last 12 months I have realized that cars with similar hp figure tend to accelerate fairly similar. Thus, with 600hp you do 0-300 in around 30s (SL65, 599GTB, LP640 etc.). With 500hp you do it in around 40s (997TT, Gallardo, F430, SL55 etc.). Just consider how much hp the Veyron needs to do a sub-20s time... The required incremental hp steps are getting huge in that speed range

The torque curve of the 997TT is also rather flat. Unfortunatly, it does not help the acceleration that much... Power is power - torque levels and curves don't seem to make a big difference

Care to re-explain your physics lesson to this MIT engineer? I am at a loss from your rationale

Impressive performance

The 993GT2 has RWD and is around 200kg lighter than the 997TT if I recall correctly

It appears that the 997TT is less efficient in transforming power into acceleration. 41s with 480hp, maybe 36s-37s with 520hp? If you aske me this is a very likely 0-300 number for the 997TTx50.

Now: adding another 100hp should result in an approximately 15s shorter 0-300 time? No way

What you are forgetting is the better aerodynamics of the newer car, as compared to the 993. Also, weight stops being a big issue at high speeds (and I thought the 997TT AWD could send 100% of the power to the rear wheels ). Basically Markus, the only way to be sure is to wait for the test results of the 618 bhp kit. Until then I will go with the figures you provide.

Very simple rationale: Look at the test data available to date. Similar hp = similar 0-300 performance (within 2-4 seconds). It is as simple as that
