The carbon fibre plenum has been designed and developed by ACT
Performance Products specifically for the
Westfield to hopefully overcome the limitation of the modified Rover plenum.For
more details, see RPi Engineering web
pages.

Side view of the carbon plenum. The plenum uses a Jaguar
throttle body and the standard Westfield 5AM air flow meter. By angling
the throttle body, theoretically the air will be spread out across the
roof of the plenum, easing its passage into the trumpets' |
| Top view, showing how the plenum flares out after the
throttle body. This is deliberate, and the idea is the air will be slowed
as it spreads. |
 |
| This is the view into the plenum, basically the route the
air will be taking after the air flow meter and filter have been removed.
The throttle can be clearly seen in the fully open position, the trumpets
can also be seen, sitting down nice and low. They should not be getting in
the way of airflow. |

respectively. See to indicate reasonable distribution. |
