How tricky was it to install?
Does pulling the cable stall then engine if you have it running normally at a couple of thousand rpm?
Behind the bulkhead, easy, there's even an unused grommet above the clutch master cylinder. The throttle end was a pita. I was going to fit a second pin to the operating arm, pointing the opposite way to the original, and couple the cable to that. The arm turned out to be undrillable, not even a cobalt drill would touch it, so I looped the cable over the original arm, as shown. It actually works better this way in that the vacuum actuator can operate without having to flex the cable, but I should really have repositioned the cable clamps, to improve the alignment. It works well as is though. The cable clamps are modified electrical connectors that I had around.
I've only experimented a little so far, but the engine seems to be quite controllable with the throttle. I can reduce the idle speed, before stopping it, for instance, so if my engine does ever try to kill itself, or inhales a flammable gas, I hope to be able to stop it slowly, so the turbo bearing don't run dry.
I have previously tried stopping the engine from up to 4000 rpm, no load, by pushing on the valve. I was able to bring the engine to a controlled stop and there did not seem to be any airflow effects trying to either open or close the throttle.
