Here are some photos of the "brain" of the 997TT. We are working on the computer as we speak. Those of you who are familiar with these computers, it looks nothing like the 996TT ECU. Additionally there is a separate controller that is not pictured that is also part of the engine functions.

 

Looking forward with great interest to your mod progress!

Have you had the TT on the dyno for some baseline runs yet?

 

Wow very interesting information, cant wait to see what you guys whip up, and learning for about the 997tt's technology and what can be changed and perfected!

Thanks for sharing. Martin

 

It will be interesting. We plan on dyno testing the car this week. I am waiting for some additional 70 MPH fans to arrive so we spot cool different areas of the car. I will be posting the process and results soon.

 

Ok Todd,

This is way off base, but what's the lowdown on that 1979 930 your working on?

-z

 

I think you should also be the first to fit the VGT Turbo's to the 996tt haha jkjk, that would be usless even if it worked!

 

if the exhaust side is vtg is there a chance you can bolt this up to another turbo?

 

Who the hell knows. I loved my last 930 and wanted another one. I have not seen this car it use to belong to "rico930" I had it shipped directly to Stephen at IA to build the motor and put it back together. That was almost a year ago. Stephan is busy as am I and it is just sitting. The motor is 450HP and just needs to be installed. Would make a great car if anyone is interested in it. At this point I am not that attached

 

....... nevermind made a new post.

 

Well let’s see, I will be testing it using my 2WD DynoJet, my friends AWD-500-SE Mustang and my AWD 500-SE Mustang when it arrives next month. The reason we have not tested it yet is because we do not have adequate cooling at my friend’s facility. We are waiting for our 5 portable 70 MPH fans to arrive so we can at least replicate some airflow. When we move into our facility in 1 month, we will be testing with our 20 HP 100+ MPH wind tunnel fan. As we have debated about on other threads, without adequate cooling and the factory tools, you are kidding yourself if you are looking for true and accurate data. Temperatures, timing and overall power is affected when these conditions change. Additionally, there are many different timing / power maps in the ECU that change and cannot be seen with a generic scanner. There is a specific data block "RON dependent Map" that can only be seen with the PIWIS. Dont worry, I have my bases covered regarding the dyno testing and we will post the differences in power with the different OEM maps

 

It appears that we will begin dyno testing next week. We started digging into the car a bit this week and we have some work to do before we begin testing. Porsche has made some major changes to the entire engine. The main components are the same but the top end, fuel system, intake, etc are all new. We have also been working with GIAC on the software which has been a work in progress. We will have more to add shortly.

 

So much for me taking a drive in it while it was stock.

Edit: (I know I was supposed to check it out Monday but the end of the month kicked my ***.)

 

Haha, amazing to see this car alreayd stripped apart, cannot wait to see what you guys have in store

 

When can we fit the 997 Turbos on our 996TTs?


...and can the 997 TT be converted to RWD by pulling a fuse like the Skyline?

 

I am not sure that would be an upgrade. I am not 100% convinced that these turbos are all that. There has been a lot of hype but from all of the research that I have done, these turbos are perfect for a mild mannered fuel efficient street car. They have their limitations and are not "lag free".
