XR6-T Torque Limiter (Actual Workings)
Ok i now know the theory of how this 450Nm torque limiter is achieved on the XR6-T.
A maximum boost of 6psi is achieved at "i think" 3000rpm and for every 1000 rpm there after the boost drops a certain amount say 1psi. So by the the time redline is reached the boost tails of to almost nothing.
Now from the seat of your pants, this makes the XR6-T behave much like a bigger capacity engine rather than your typical japanese turbo powered cars that tend to have a big top end rush.
What my question is how is the boost at the turbo lowered as the rpm increases?? I mean since the turbo itself is driven by exhaust gas's is there a mechanism that limits the exhaust gas's spinning the turbo, or is there a diaphram on the intake end that restricts air comming into the intake.
