Temp - hot as I can get it - dip pre-seasoned steaks in butter bath and drop on hot as heck grill. Rotate 90 degrees after 2 minutes or so and flip, passing by the butter bath again. Steaks are done pretty fast. Sometimes if I have a lot of steaks to do or they are extra thick, I'll turn the second side of the grill on low and let them 'rest' and continue to cook 5 more minutes, they turn out perfect medium rare +.
(skirt steak pictured), a lot shorter for these naturally but same concept.
