Hello everyone,
I’ve just wrapped up my fourth week with APR and continue to learn a ton. This week was especially exciting—I got to be part of some really cool projects.
To start the week, we figured out how to enable an Audi to build boost during launch control. This allowed the car to launch more quickly by eliminating turbo lag. After getting the system working, we began calibrating it for smoother boost control throughout the launch and into higher RPMs. To do this, we used the dyno to measure various metrics during testing. This let us modify the ECU (Engine Control Unit), make improvements, and quickly rerun tests.
APR Intake installed
While on the dyno, we also installed an APR cold air intake to measure its power and torque gains. A cold air intake replaces the factory intake system with one that draws cooler, denser air from outside the engine bay. This improves combustion by increasing oxygen content, which can lead to better performance and efficiency.
I also spent another half day getting a look at the business side of APR. It gave me valuable insight into the challenges and processes beyond engineering—things that are just as important but often less visible. I walked away with some key takeaways that would be hard to get anywhere else.
Outside of work, my host family has continued to be incredibly kind—they’ve truly made me feel at home. I spent some time with them on the lake this week, went on more walks with their dog, and kept up with my workouts.
As week four wraps up, I’m grateful for everything I’ve learned and experienced so far. It’s been an amazing time here in Alabama!
Well, Eli, you seem to have learned a lot. Will you now appreciate the Dodge Stealth TWIN turbo a bit more when you are back home. It’s not an Audi but it was built in 1993 – pretty state of the art for a car dating from 1993.
