Earlier in this thread there were some skeptics who had a hard time believing the power we tested on our new 997.2TT. Well the new April issue of Car and Driver tests the ZR1 Corvette against the 997.2TT. There are some very serious numbers that where put down by the new turbo which further confirm the tests that we conducted. Here are the specs from C&D:
ZR1 vs. 997.2 Turbo
0-60: 3.4/2.9
Rolling 5-60: 4.0/3.4
0-100: 7.6/6.8
0-150: 16.4/16.2
1/4 Mile: 11.5 @ 128 vs. 11.0 @128
Top Speed: 205/194
Laguna Seca Lap Time: 1:36.8/1:37.8
Additionally, I just got word from a few of my associates in Germany that have been dyno testing the new 2010 turbo. All of them confirmed that the power of the 2010 turbo is under rated from the factory. 3 different cars were tested on 2 different dynos and all of them showed ~528 HP stock on both dynos. The German dynos used measure engine power which calculates the parasitic losses through the Drivetrain.

Why would Porsche understate the power in the 997.2 turbo? It's strange because the accelaration times were indicative of much more than the 20HP increase over the 997.1 turbo. It appears that there are significant increases and advancements which is great news.
I can't wait to see your further developments and your tireless dedication to your (and mine) passion.
Thanks.

I just finished sorting through the data logs from the new turbo. Pictured below are a 2 screen captures from one of the programs that I used to log the car both on the street and on the track. There is a ton of useful data and I thought I would share a snapshot of what the data was stock vs. with our software tune.
Pictured below is a screen capture of a few data channels from one of the logs during highway driving - 100% Stock 997.2TT with ~ 1200 miles. You can see the Manifold Pressure, RPM, speed, intake temps, engine compartment temps and fuel trim. This data was recorded from a quick blast on a closed highway.

It would be great to see some more high speed acceleration data to nail what is going on..... 0-150mph in 16.2 is 528PS/PDK fast - maybe it suffers from some catastrophic heat soak over 150mph and its hp drains away with reduced boost and pulled timing ? Wouldn't be the first Porsche to pull this trick but certainly the first factory tuned one.

Real Porsche 528PS in a 997tt body would do 0-300kph in ~sub 36s. In the only 997tt.2 test to date by (Sport Auto magazine) it took 41.9s (it also did 0-200kph in 10.8s so was in good health !)

Something is just not right. How can it just loose all that power after 200kph. Heat soak could be a variable but if you think about it will they really bring out a new car with intercoolers that won't be able to support stock power? Something is up.

What Toby is describing is absolutely possible, explaining the huge drop off in acceleration beyond 200 km/h. Take a look at manufacturer's datalogs for temperature IATs with the stock intercooler systems for the 997TT and 997GT2. With ambient temps in the low to mid 20C, runs beyond 4th gear WOT bring IATS close to 50C.

I am still confused though, because the way it takes to reach up at higher speeds is just not proportional. I read somewhere that it takes the 997tt.2 more time to get to higher speeds than the 997tt.1 However up to 200kms the 997tt.2 just kills the 997tt.1 Can you see where I am coming from. I just don't get it. Dropping off speed on the high end is fine but at least it should not be any slower than the older generation as they are all able to get heatsoaked.

I think that this is correct. When on the track, my oil temps got VERY high and I could feel the power start dropping off. We will be testing this car at the Texas mile later this month and I will be sure to perform some 0-300 KM runs and get back to you.
