Power is one part of the package.

AWD Tuning’s original post documents Mary Fields’ 2024 Subaru WRX, Cinderelli, at 388 whp and 417 wtq on E70. The same feature records an XClutch 240 mm single-plate clutch installation.

Why this example matters

A tuning discussion should include how the car will be used and which supporting parts are installed. This example puts the clutch alongside the engine’s reported output, making the drivetrain part of the conversation.

What the numbers tell us

These are the figures reported for this particular car on E70. They are not a promised outcome for another WRX or another fuel blend. The source does not provide a complete modification list or enough dyno conditions to make a like-for-like comparison.

Planning your WRX?

Start with the exact model year, modifications, current calibration and fuel you can obtain consistently. Tell Keith whether your priority is response, daily use or a staged project.
