Turbocharger shaft axis orientation

Chapter: C5

In Simple Terms

The turbocharger shaft must be oriented in a very specific way: it needs to point along the car's length (parallel to the centerline) and sit toward the inside of the engine bay. The shaft can only tilt up to 1 degree from perfect alignment with the car's direction.

  • The turbocharger shaft must be parallel to the car's centerline (Y=0)
  • The shaft must be positioned inboard (toward the center) of the Y=25 measurement line
  • The shaft can only deviate 0 ±1 degree from the car's lengthwise axis (X-axis)
  • This strict alignment ensures standardized turbocharger positioning across all F1 cars
Official FIA Text

The axis of the turbocharger shaft must be parallel to Y=0, inboard of Y=25 and at an angle of 0 +/- 1 degree to X=axis.
