Testing the Overtake VB WRX Turbo Inlet on the Dyno
What’s up everyone, Art here. Today, we took the VB WRX on a short road trip to JM Automotive. You’ve seen them in our previous videos, they’re one of the premier tuning and build shops in the area, and they’re where we always go for product testing.
This time, we brought along something that’s been highly anticipated, the Overtake VB WRX Turbo Inlet.
The Plan, Baseline, Install, Test
The goal for the day was simple. First, we put the car on the dyno in completely stock form to establish a baseline. Then we installed the Overtake turbo inlet, ran the car again, and measured the results. No guesswork, just real data.
After finishing several baseline pulls with the factory inlet, we let the car cool down briefly and got to work on the install.
Factory Inlet vs Overtake Inlet
With the stock VB inlet removed, one of the biggest questions people ask is, what’s all the extra stuff on the side of it?
What you’re seeing is effectively a built-in boost leak. The factory design creates a venturi effect that draws vacuum through this section, which can negatively impact performance, especially as boost levels increase.
The most noticeable external difference with the Overtake inlet is the absence of coolant lines. We loop those lines together underneath the car, which simplifies the setup and removes unnecessary heat and complexity from the inlet itself.
Installation was straightforward, and honestly, the Overtake inlet went on much easier than the factory unit came off. Not dealing with coolant lines was a huge improvement.
Dyno Results on the Stock Tune
Once installed, we ran several back-to-back pulls and reviewed the results.
The baseline run, a completely stock car on a completely stock tune, is shown as the black line on the dyno chart. With the Overtake inlet installed, we saw gains across the entire powerband:
-
Torque gains of roughly 9 to 10 ft-lbs, tapering slightly to around 7 ft-lbs
-
Horsepower gains of 5 to 6 wheel horsepower all the way to redline
Seeing a consistent 5 horsepower gain with no tuning changes is impressive on its own.

From there, we moved on to a tuned setup using a standard off-the-shelf tune. Timing was adjusted slightly to ensure the car stayed knock-free, and then we increased boost to see how the inlet performed under more demanding conditions.
On the top end, the car was making just over 20 PSI. Comparing the stock inlet to the Overtake inlet showed:
-
Around 7 ft-lbs of torque gained across the powerband
-
Roughly 5 horsepower gained up top
These are strong, healthy gains from a single mechanical change, purely from improved airflow. Beyond the numbers, the simplified design and rerouted coolant lines make this a cleaner, more refined package overall.
Final Thoughts
The VB WRX platform has a ton of potential, and this inlet is a strong first step toward unlocking it. Whether your car is completely stock or already modified, this is an easy install that delivers measurable results.
