Welcome to RL, Great data, thanks for posting!. Do you mind sharing a bit more, when was this info gathered, how, car weights etc..? Any graphs?
I don't understand your last post
Slope % is important for sure, but it is the shape of the slope throughout the run that matters, you could be running 10% downhill for 90% of the run distance and then go uphill 30% for 50 meters at the end and show a small slope variation. It is great to catpure it though

these runs were gathered during the last half year. All done by my driftbox. The fast figures are quite heavily modified 997 from Tuner 9ff in Germany. E.g. the Gturbo has 4,0l and many other mods.
you are perfectly right with your assumption of the slope. the corrected time is only calculated with the average and not sample by sample.
But if I compare my many many runs I have meanwhile, this simple correction behaves very well and brings the value of the same car closer together. the statistical error gets smaller.

RS38
Welcome to Rennlist
This seems to be the tool which RS38 has created to work with DB files ? (from Rennteam)
http://me-fx.de/dbscanner.zip
I am guessing that you have some affiliation with 9ff as you seem to have some great 9ff data ?
If you are a 9ff "insider" can you share with us the 9ff philosophy on producing these very high hp motors ? Obviously they are built to give the awesome acceleration numbers but can you give us an idea of how long they last before rebuilds and what sort of customers are buying them with the costs involved of say running one on the street ?
I remember Jan being quite candid about this aspect in a magazine interview saying his 800hp 996tt creation needed a serious rebuild at 10K miles, how do the even more extreme offerings fare ?

yes, I mean that tool. It turns out that more people like it than I ever expected.
and yes, I know many of these 9ff cars and guys including Jan Fatthauer, but I do not have any business relationship nor I have tuned my own car there.
I cannot say too much about rebuilds etc. as I don't know. Most of the potential problems with high hp- engines originate from very high torque.
These very fast 997 Turbos from 9ff are build from a GT3 base, so they get more power by using revs instead of too much torque.

The other thread got a bit hijacked and ended up a great discussion about theoretical physics -so here is another one to log 100-300kph times and hp claims.
OK so 60-130mph tells us quite a bit about hp of Porsche turbos and more importantly "relevant" hp, this is the power one uses for daily driving, squirting past other traffic, stop light races ( ) etc.......
As we know, Porsche hp is renowned for its staying power, for hanging around when things get hot and other manufacturers engines start heat soaking and dropping way below their hp ratings.
The Ultimate hp test IS the 100-300kph (62.1-186.4mph)
It is unachievable for most, even with big hp you need a good straight couple of miles to do it - public roads are a definate no no.
Obviously areodynamics start to come into play in a big way over 120mph so one should bare this in mind when reviewing the numbers.
Autocar published some great data today which will set the benchmarks for this thread, times achieved at the VW proving ground:
100-300kph (62.1-186.4mph)
Bugatti Veyron: 15.7s
Ferrari 599: 26.4s
Murci 640: 28.4s
Ford GT: 29.7s
Merc SLR: 33.1s
997tt: 37s
Corvette Z06:37.8s
Other Sport Auto Published data:
996ttGemballa750: 17.6s
RS Tuning 993tt (special aero body)533hp: 22.2s
RS Tuning 996GT2 542PS :24.8s
Carrera GT: 30.4s
On to your esteemed RLers (AX22 data)
Guy R (Ruf GT2 Nardo): 24.8s
TB993tt (520hp mode) : 30.48s
Leon S (Ruf TurboR special): faster than 30.48s
I like looking at this data (anorak) and will update this thread as and when it comes in.

Now I have also something to say to this thread

I used that Marston (9M) IC. Max IATs were about 38 celcius. But that thing is not simple..
I had also IC cooling temp and air filter temp sensors and I noticed that when pushing hard, +250kmh, air filter temp also raised, from +5 to +25. That is not good and must be "fixed" somehow.
IC cooling temp was -5 but when cruising it dropped to -10 but when pushing hard it raised again to -5. And after idling two minutes it raised to +20 and so on
These things are quite interesting and complicated.. maybe I should open a new thread and show these results..

Hello Jussi
Really impressive run. Is the air filter picking up air that has passed through the intercooler? If so can you put a scoop or similar? Do you have a pic with the 9m cooler on?
best regards
Steve

Yes looking at the data will be very interesting 
I think it will take you quite some time to figure out everything that was going on but the results and findings will be great. I would not pay too much attention to IATs in such outside temps, it will not be representative unless you have a benchmark to compare to in similar conditions though. You need a new thread to fill us in to all the detail

Posting for a good friend who had a banner day at the TX mile. 0-300K in 15.95 sec and 100-300k in 11.44. Terminal speed after the standing mile was 231. Full weight car running a new engine config...
