Vivid Racing’s Porsche 996TT project has been one of the most indepth and learning experience cars we have done. Having engineered and tuned many new parts for the 996 Turbo market from our car, we still have the urge to keep going to the next level. After the completion of our 650 Turbo Kit, we wanted to squeeze some more horsepower out of the car. We needed more air flow and more fuel!
First, we added the Innovative Auto Intercooler Pipe Kit as seen HERE. This pipe kit is designed to replace the factory intercooler cooler ducting which is very restrictive due to the shape of the pipe behind the motor and its cast piece to the factory intake. The Innovative Auto component features an aluminum intake tube that flows much more volume of air without any major restrictions like the factory unit. The kit uses strong durable flex hose to connect to the turbo inlets for the best air flow possible. Suggested, this kit is suppose to add 30-40 horsepower to basic stage 2 cars… We are testing that now!
Next to keep the air flow going, we added our Prototype Agency Power Intake Plenum. The 70mm plenum features CNC machined flanges to connect to the throttle body and the stock intake manifolds. The curved piping helps the plenum direct the air in a more efficient manner as well as increase volume. This part is a direct bolt in replacement of the stock plastic plenum. Suggested, the plenum should add about 20 horsepower on a stage 2 car… We will see!
Finally, to increase fuel, we upgraded the factory injectors with RC Engineering 60lbs injectors. These injectors are a direct replacement for the stock ones. Fitting in the fuel rail with no modifications, the injectors are designed to reduce the injector duty cycle percent as we increase boost and advance timing for more power. View our fuel components HERE.
These 3 modifications are very labor intensive. As seen in the gallery, the entire engine had to be dropped. Our technician was able to pull the motor and put it back together in 2 days. While the motor is out, it is a good time to replace your clutch, we skipped it though 
.
We plan on finishing our ECU Tuning and will have new dyno results shortly, so stay tuned….
