Project Not Ours – Porsche 997.2 Turbo - 7,186 views
Well the title says it I am still in love with my 997.1 Turbo so instead of moving to a new 997.2TT right now, a gracious customer has allowed us to do some R&D and show off what we can do with the 997.2 Turbo cars. Instead of the in your face loud style that we did with our Project 997TT, this will be more about the development of each part, what it does, and why. We are focusing on the small add ons to help improve function, driveability, and overall performance. There are many paths to take when modifying your 997.2 Turbo, this is simply another solution.
The story starts…
This car is a new 2010 997.2 Turbo with the PDK transmission. It has the break miles completed and is BONE stock. Out here in AZ we get 91 octane and as I type this, it is 95F outside. The first step in modifying this car will be the ECU update by VRTuned. VRTuned connects to the car via an OBDII cable connected to a windows based laptop. The process for reading and writing files is here. The car comes stock with 500hp to the crank, also know as BHP. But as always when you dyno test, it is in wheel horsepower. Vivid Racing uses a Mustang ALL Wheel Drive dynamometer to get its results. One hiccup with dyno testing “automatic” cars is they like to downshift when you just floor it. So you have to roll into the throttle which takes a couple of tries to find the edge (thanks Ian @ EVOMS). When VRTuned tunes the ECU, they are adjusting boost, fuel, and timing maps. The DFI cars are different then the previous 997.1TT with the amount of boost that it will run. Overall, we expect to see around a 60-80HP gain. But those results will be proven later.
As we tested, the car made 444awhp and 443ft/lbs of torque. This was run with Sport mode off and in 3rd gear. You can see the graph is moved to show starting at 3500rpm as before that we had to light roll in on the gas so the curve was to say the least… odd.
Anyways here is the graph and video. We got some cool things coming up so stay tuned
