Just came back from a 1 hour test drive with a modded 993tt.
It has a cargraphic kit done by shk tuning in germany. don't know exactly which kit it is. Owner said 510PS. Cargraphic has 493PS and 520PS. Torque is like 650NM. Whatever kit it is I am soooo sad that it did not satisfy me at all!

It did spool up faster, boost came on at lower rpm and stronger. Felt like driving a bigger displacement engine. BUT the driving sensation was in no way like "WOOOW" but more like "ok", just a little bit more.

The (stock and first) clutch once slipped in 5th gear at WOT but could handle the torque well otherwise. Car has like 43K mls.

Owner said he made a 328kph on the digital. Seems reasonable to me.

I am disapointed to say the least. Will try to testdrive a turbo r and a modded 996tt or gt2.

Can't believe that I have to go to the extreme like Jean did just to have the power I want and feel I "need" on the autobahn. Sad day.

Stummel, that's very vague.. Did you have a stop watch? Did you pull some 60-130 times? That should be your benchmark.

I highly doubt that he has the 510PS or 520PS kit. There's no way that the Stock clutch at 43K miles would last.

Stummel

Kevin, I had no real measurement. The stock boost gauge was the only "instrument". And indeed the boost in 2nd gear went almost instantly to 0.8 bar when with my stock 430ps I hardly get to 0.8 bar in 2nd at all. Same in the other gears. In 6th gear I had 0.8 bar at ~2500 rpm. Stock is more like 3200 rpm. The boost was there but not the speed or acceleration if this makes sense. Perhaps it was all about the clutch and I did not notice when it slipped just a little bit? Could that be???

He paid ~35K Deutsch Mark i.e. ~18K Euros for the conversion in yr. 2000 with 25K mls.
That is with turbo s front chin spoiler and cargraphic 18" wheels. He also had an upgraded IC for ~3K Euro!!! Though the IC had stock size.

Just to get it right it had more power than mine but I missed the Wow-effect. If he did a 205mph top speed on digital gauge it has to be around 500hp. I do not think that the guy talks BS.

Regarding the stock clutch, the ruf turbo r kit does not contain an upgraded clutch.
@Bill: Do you have the stock clutch?

I would be very disapointed spending a lot of money for turbos, ecu and IC and ending up with that kind of performance.

Hmm, my stock '97 TT will hit and hold .8 bar in 1st through 5th (track tested :-)

Sounds like you have been spoiled by Jean's monster.

There is only one answer for you:

Just re read your post. SHK were the outfit that joined with Cargraphic to make the "Black Snake" 993tt with the 652hp/812NM engine. The 1270kg car did the ring in 7:46.17 seconds. SHK used Sportec to do the engine management in this car. I think I mentioned to you (or someone) before that the owner actually swapped out his 652 motor for a 520hp RS engine after he test drove one and realised his was much more peaky and not as nice on the road.
Maybe the car you drove was from the era when Cargraphic worked with SHK and before they went solely with RS kits. From the "510hp" rating it doesn't look like an RS kit ?
I can't imagine you would feel any disappointment with 700 RS Tuning NM, which is what you get in the basic 520 kit

VerySideways

Wow, that's actually quite cheap for what it is - 20,000km and all...

Stummel

TB and VerySideways,
The car on mobile is not exactly what the add states. The mileage was very hi, the 20tkm is after the engine mods. But I try to sell mine and buy this if a ppi checks out ok.

The SHK / Cargraphic ~500hp kit was done in early 2000. Do not know if back then Cargraphic sold only RS kits.
What is remarkable is that it does not use the stock Intercooler! But the one used looked not too different from stock. The IC was silver colored.
I think RS would not change the IC on a ~500hp engine, but rather change the clutch???

Stummel,
While you're at it. Why not go for a original 993 GT2 EVO?

Only €185.000 .....

Stummel,
It is all about compromises. While my car is perfectly drivable on the street, it is not what I would call a daily driver. Together with 650-700hp come a lot modifications needed that make the ride less than a pleasurable one.

I am assuming that you are looking at a car that you can drive both on the street and the track. If you are to drive a car like mine on the track, you have no choice but to go with stiff suspension and fat tires, a roll bar (at least) and pagid pads most likely, and a ^%#^# clutch, which means that, once you are back on the street, you will be driving a hard car, not a car in which you can take your girlfriend or wife out for dinner (if you want to keep her). The exhaust sound is quite loud as you might recall, although that was with one pipe welded closed for the 'Ring, it is not your typical cat bypass or muffler bypass sound, I agree that the sound is not an issue as you can add a more restrictive muffler and loose a bit of hp that you most lilely will never need.

Net net, for a car that you will drive often, a 550 real HP is very good. If you like the rush of a hard acceleration, then you can go with an EBC and set your boost and ECU program to run an occasional 1.3-1.4 bar, and you will get the adrenalin rush for sure.

That RS car seems very appealing, the price is 58k Euros ex-Germany (and EU), which is a bargain. I have a friend looking at it right now as well. If turns out clean, jump on it.

Most likely the issue was the clutch. I just had mine replaced - and my car is stock - it feels much faster.

Stummel

Peter,
How many miles does the car have?

TB993tt

The clutch is a red herring, you can easily feel the clutch slipping, especially on a test drive in Germany in 3rd, 4th upwards WOT will make the combination of high torque and weak clutch very obvious, and smelly

Stummel

As I wrote the clutch slipped once very obvious in 5th gear at WOT with rpm going from like 3K to 5K in a fraction of a second. In the lower gears the clutch was no issue.

Peter S 993tt

My car as 33000 miles on the clock - you can't always feel it slipping - that's the strange part. When you replace it though you feel like you have just gotten a new car. The key is that the original clutch is the dual disc and dual mass flywheel require a very hard pressure plate that tends to stiffen over time - they usually go between 30-40 k miles, and that's with the stock 408 hp. Kick it up to 550 hp and the clutch will not be able to handle it. One sure fire way to tell if it is shot is that the pedal gets hard when you depress it with the engine off (can't tell with it on because of the power assist).
