To maximise the potential of Torque Multiplication, the Trident Iceni has a mid front mounted 6.6 litre V8 turbo diesel engine, complete with common rail, direct injection, 4 valves per cylinder and a variable
vane turbo.

This is a vacuum actuated variable
vane turbo and the control system seems to be working (the ECM is able to modulate the amount of vacuum, and the actuator moves in response to the ECM's commands.
While the history books list various iterations of that Beetle - inspired, air - cooled and carb - fed flat - four, the unit codenamed EA9A2 is an all - new, direct - injection variable -
vane turbo 16 - valver.
Not exact matches
Normally, a VNT
turbo is larger than a standard
turbo, as the variable
vanes help it to spool faster.
What information is used to to inform the state of the
turbo vanes, though - throttle position, intake air mass, engine speed, or what?
Overall, the position of the
vanes is dependent upon how much boost the
turbo is pushing.
A second way on controlling the
vanes and boost, is to have a single canister on the
turbo to control the
vanes, and control the boost level with a wastegate on the manifold.
The VNT
Turbo has movable
vanes on the exhaust...
The solenoid valve controls the boost by moving the vacuum actuator that controls the
turbo vanes.
Each
turbo comes with a 100 % new
vane actuator, journal and thrust bearings, and is 100 % end - of - line tested to ensure desired performance.
Among the visual changes for the GTS is a Cayenne
Turbo - style front bumper, unique sills underneath the doors and a twin -
vane wing atop the tailgate.
Thanks for posting, good to see the
turbo is a dual -
vane for reduced
turbo lag.
Making use of an electronic wastegate for each turbocharger for faster response as well as more precisely varying
vane positioning, the single - scroll turbocharger design allows for the use of smaller
turbos to reduce weight and improve packaging, while still meeting power and performance benchmarks.
