What are the limits of the LS7 clutch? I have the LS7 clutch, 13lb Fidanza flywheel, and the Tick adjustable master. Some engine changes I'm considering have me worried that this clutch will not be adequate.
I'm completely happy with the current combo in my applications, so if I am forced to change I would prefer to stick with an OEM solution if one exists which is a reasonable cost. It's a 99% daily driver that sees very limited exhibitions of speed on the street, and a few autocross/HPDE style events each year.... no drag racing or drag tires.

When I spoke with Martin @ Tick, he indicated around 440rwhp would be the most you could reliably run through it. The LLSR LS3 setup's are intriguing me and I'm just wondering how it would do in the upper 400's or low 500's depending upon combination.

OEM LS7 has over 500hp as standard.
That's a factory car, with a factory warranty. Even at 440rwhp I'd like to think that should be a breeze for it unless the driver is a complete nutjob, especially as you also state no drag tyres or drag use.

By upper 400's or low 500's I meant RWHP not flywheel. I'm researching a setup like in this link, except it'd be in a F-body chassis so the pre-manifold and exhaust would be a little different. Not sure what type of power penalty those differences will make.

Your current set up is probably making some decent power already, is the clutch holding for your a/x, open tracking use now??
IF you were going to be using 315+ wide A7 gumballs for MANY autocross starts a month, maybe you could think of going to a stronger clutch, but for street/HPDE/occasional a/x use, on nothing stickier than the NT-05s in your sig, I would think that the LS7 would be just fine.

I haven't taken it autox'ing or to an HPDE since it was built. Just got tired of the lack of seat time of the former, and the oil pressure concerns for the latter.
I feel there is something wrong somewhere due to the curve peaking around 5500-5700RPM (420'ish) and then a straight slope to 400 at 6500. So that's part of my reason for me to rebuild the top end.
