997 Turbo Cab Construction - Project Not Ours
We have been wanting to get our VR825 kit out there on more vehicles since we proved its capabilities on our own Project 997TT. Having reached 206.2mph at the Texas Mile and laid down 760awhp on a Mustang dyno, we knew that with our Agency Power products and Softronic tuning, we had a very quality kit on our hands. Taking a look back (and look forward), one of the biggest things we wanted to change was the injectors on the kit. Our 6speed still runs the stock injectors and with these GT3076rs turbos, handles the power fine. But to get to that next level, we need to step up the fueling game. This kit went through 2 phases when it was being built and has only been installed on a handful of cars globally. So to show again what this VR825 kit is capable of, we needed another subject vehicle. But instead of a 6speed, we wanted to show that the Tiptronic, when equipped, is a brutal force to be reckoned with.
Our subject car is a 2009 997 Turbo Tiptronic with 13000 miles on it. Coming from Alabama, this 93oct car is already equipped with the Agency Power Exhaust, Headers, Cold Air Intake, and Softronic ECU Flash. The cab is a black on black beauty and looking to achieve some stealth high horsepower while keeping it very reliable. Our VR825 kit has been functioning for almost 2 years with approximately 5-6000 miles on it. What I enjoy most about the car is its feeling of stock when you are just driving it to and from work on the city streets. However when you hit boost and the external wastegates open, the car is an absolute animal. Whether on pump or race gas, we are able to achieve functionality for everyday use.
The first question to be asked is, "what are you going to do about the Tiptronic transmission?" The Tip is the weak point in these higher HP cars. There is alot of talk of modification processes. We are going to take 2 different roads then normal to achieve a stout transmission to hold the nearly 800awhp. Something that is affordable andreproducible without compromising drive-ability. Details coming soon...
As standard on our VR825 kit, this will include our external wastegate headers with dump tubes to bolt up to Garrett GT3076rs turbos. Instead of using Tial wastegates, we are going to be using the new Turbosmart Comp-40 wastegates. These wastegates feature a smaller head for better clearance while still providing quality flow and heat protection. Our kit also includes the Agency Power intercoolers, twin blow off valves, fender mount intakes, larger throttle body/plenum, new 3inch Y-Pipe, and a handful of other goodies. The adder to this project will be 76lb Siemens injectors. Controlling the high and low boost via a Greddy Electronic Boost Controller, these injectors will allow us to further the power we will be able to obtain.
This project will not be all go and no show... To give it a better stance, we will be lowering the car with H&R springs. The biggest upgrade will be the addition of a VorsteinerVRT aero kit. Their new front bumper with carbon lip spoiler, rear bumper with carbon diffuser, and a Cab first, we will fit their VRT rear wing to the car. We plan on doingalot of updates on our Project Not Ours blog as well as adding images to the gallery. We want to show the quality in our parts and manufacturing process, so expect videos on our YouTube Channel too. So stay tuned there!
So what is the first step? Baseline the car... On a Mustang AWD Dyno in standard mode, the car made 460awhp and 537ft/lbs of torque. As seen on other tiptronics and even the PDK, these are torque monsters. But this car is lacking a little. From the curve, you can see how it breaks up at around 4000 rpms. This is usually from plugs. When you do a flash and add the additional bolt ons, the horsepower and boost increase can affect the stock heat range plugs causing a failure earlier then the recommended time to change them. Don't worry, this is in the build
So it begins!

Pulled the tranny out last night. What a pain says my tech compared to a 6speed! The Torque Converter is being removed and then being sent out for the mod. The tranny is being opened up so expect to see some step by steps of the process!

The only changes to the VR825 kit will be these headers pictured and switching to the Turbosmart Comp40 wastegate. Everything else will remain the same (ypipe, intercoolers, bovs, etc. The extra add-on will be the 76lb injectors like you run to be tuned for more power. So with injectors, maybe we have it a 850 . Obviously like yours, the tranny has to be updated which through people like yourself, we have learned what is needed.
BTW your complimentary upgraded headers should be ready in 2 weeks.

i saw the headers , karim told me about it , and yea am waiting it and will post thread and pics when i get it ..
good luck with this project .. keep us posted

Lookin' Good
Dan,
Looks like things are coming together, can't wait to get it back and give it a try!

So if your wondering what a Tiptronic transmission looks like all disassembled, here it is! The main purpose of rebuilding a Tiptronic is to increase the fluid pressure/circulation and the disk material. You can see how many clutch packs are in here. So stay tuned!

dan , i would like to ask you about the turbos in VR825 which am running right now !!
could you please tell what is the :
1-compressor Wheel Info ,Inducer,Exducer and Trim ??
2-Compressor Housing ?
3-Turbine Wheel Info ?
am asking that because i may upgrade my turbos and replace them with GTX3076 in the future .. am just wana know all the info about my turbos righ now ..
thanks

The turbos are a standard Garrett GT3076rs with a .63 a/r. Here is the turbo data - http://www.turbobygarrett.com/turbob..._700382_12.htm.
The GTX map is here - http://www.turbobygarrett.com/turbob...R_803713_1.htm
I dont think your going to have any advantage doing that really. You could switch and go with the .82a/r but the turbos will spool later and make more top end power.
The turbos on this car are using the new anti-surge compressor inlet as you can kinda see in the pic -
If you want to step up to MORE power, I think doing something interesting is possible. We just need to keep the clearances so the turbos will fit in the same location. Those turbos are capable of 520HP each. So you still have room, I think the limit is the boost so building the engine would be better.

The short of it... you know when you are lightly on the throttle and only build about 5psi of boost and you let off the gas and here "whooop whooop whoooop". That is compressor surge as you dont have enough pressure to blow off from the blow off valves. So the air travels back down and into the compressor slowing down the turbine wheel. The anti compressor surge inlet has the which then moves this air from going directly into the compressor side...
