This shouldn't be a problem for us hypermilers since we hardly ever rev that high, plus the engine will get killed after returning to idle at the soonest, to allow the turbo to cool off somewhat.
Ecomodded, someone here once remarked that kill switches should be of the momentary type, since it is possible to push and forget, especially if something suddenly grabs your attention. I believe there was something about a situation when he needed to bump start fast, but forgot to flip the switch and the engine wouldn't start. Lots of panic but no serious consequences, thankfully.
Just something to keep in mind.

That is high. My 1.6 turbodiesel consumes ~0.52 liters per hour (~0.14 GPH) when warmed up. Even with A/C on it's between 0.8-1.1 LPH (0.21-0.29 GPH).
BTW, is your PS pump electric, or is it run off of the engine?
