[750hp]

Noise shouldn't be too bad, as they are still using helical gears. I can't see that any of their options are for clutchless shifts though.

I love the look of their "1400hp" rated 1st to 4th gear option, using standard OD 5th and 6th gears. Seems to make perfect sense.

Only problem I can figure, and it's something that I haven't looked any further into with the T56, is how strong the standard case is. I know that Mike Long from G Force transmissions makes some beautiful race gears / shafts / sliders for the T5 transmission. Throw too much torque at it though, and the main/cluster shafts can't handle the load and just push themselves apart, taking the case out with it...
