Last time we posted about this Forester XT intake project, we left you off with prototype fitment. Testing is now complete and we have some information to share. Our initial goal for this project was to design a performance intake system that would deliver dyno proven power gains and while being safe to run on the stock tune. We designed a very similar system for the 2015+ WRX and achieved terrific results. The Forester XT has changes in the ECU, head design and cams, … Continue Reading ››
Our last update on this intake included dyno testing that yielded some interesting numbers. Now that we’re moving closer to the release, let’s take a look at the finished product! Let’s start with the intake pipes. These intake pipes will be finished in either wrinkle black, wrinkle red or polished, as shown above. The decision is up to you! These production samples came out nicely and look really great in person. Remember we are using full three inch piping with no step downs, which will require a tune … Continue Reading ››
The progress on our intake system is coming along nicely for this Forester XT. We have created a pipe that will fit well with our airbox design and filter selection. Remember, our pipe is within the acceptable pipe diameter to run this system with a stock tune.
The Fabricated PrototypeBelow are some shots of the system we plan to put on an FXT for testing. The routing for this tube will follow a more direct path from filter to turbo. This is especially helpful for when the car is sitting at idle with ambient air around the box. With a shorter … Continue Reading ››
We’ve got some interesting plans to evaluate the performance benefits of our TGV delete kit. In addition, we want to evaluate any appreciable differences in terms of air temperature between the two materials (aluminum and Delrin) we have selected for our prototypes.
Test PreparationFor our first assessment, we will evaluate airflow temperatures in both materials during dyno testing. The goal here is to determine whether the different heat transfer properties of the two materials have an impact on the airflow within the TGV unit. Ideally we would use pre-TGV and post-TGV sensors to evaluate this, but for our initial test a … Continue Reading ››
We’re back with another quick update on our TGV delete project for the 2015+ WRX. After designing our initial models and then 3D-printing a prototype for test fitting, we worked up a couple functional prototypes for on-car testing.
