It is still holding, but I don't think you'd be seeing the same thing getting a fat little F-body off the line with that clutch...

Running a car on a chassis dyno and launching one on drag tires are very different. Just because a clutch hold on a dyno doesn't mean it will hold at the track with traction.

I'll give you an example I am aware of. Textralia's testing was done with Robby Bolger's 4 door (crewman) Drift Ute which is on the order of 6000 lbs. It made ~1200RWHP, and did tons of dyno testing.
But, that clutch has been tested at the dragstrip on cars making 700 RWHP, thus you see them rate the clutch at ~700RWHP. The real test of the LS7 clutch will be to see what it does on the track, or see it hook somewhere with some sticky tires. You could realistically probably get away with a Ls6 clutch on the dyno. But when you get on the street it would get ugly. A real test of the LS7 clutch would be if HPE to move it over one bay to the Mustang load dyno they have and see if it'll hold. HPE hold the distinction in Houston for having both a dynojet and a Mustang Dyno which is great for testing and comparison.
I also agree that it will be interesting to see what it does in a heavier F-Body with some tires and suspension.
It is also good to note that clutches are normally rated based on torque capacity not sheer HP. On the sales side, thats how they are sold since most folks relate better to peak HP, and not peak Tq.
I do applaud HPE for the videos, and for making things exciting in the LS7 world. Its good to see shops push the envelope. I'm interested to see what will happen when shops can tune the current PCM like the current Ls1/Ls6 market.
