Geoff,
In one of our early Power Assurance Checks, we did it at low weight and had to restrict the Single Engine Tq to 90% to keep the thing on the ground. Even at that, it was starting to dance on the mains with the oleos well extended! I didn't try, of course, but it had all the feeling of being able to fly away!
If I recall your demos in the Sim correctly, 70% Tq gave us 140kts at 6400kgs. Bring one engine off-line and the Tq went to 140% on the remaining engine which, happily is the Max Continuous OEI!!! Similarly, 80% Tq gave us 160kts. Engine off-line and Tq went to 160% and so on.....
I do hope it never happens though, much cosier feeling with both of them churning away behind you!!!!
