LS7 clutch problems?

I have and like the Ls7/LS2 setup. It handled a few 5000+ dumps on MT ET Street Radials fine, but I try to be a bit more gentle usually as my car weighs almost 4000 and has the stock 10 bolt.
Key is:
New slave... just do it, it would suck to have to reinstall in a few months if the 'good' slave fails later
New master, if you do not have the 2001/2002 model already
Drill mod the master hose
Bleed the assembly OFF the car... yes, you WILL have to remove the master from the car (gotta take it out to replace or do drill mod anyway), both parts together
Install all parts spotless clean.
Mine was slightly low pedal at first, and dead on after a day or so. Had to do NO bleeding on the car.
It does rev abit slower; the heavy flywheel helps a lot launching and doesn't seem to be a problem at all in 'spirited driving'. Full on road race might want a light flywheel... but if you street or drag heavy is nice.
As for 175 shot and 6k launches - yeah you need to spend a bit more and go dual disk or Textralia or the like. (Or T400 / 4L80E if you intend to beat it that hard regularly)

Thanks for the tips guys, I'm actually on a 20k mile spec 3 clutch right now. I've already got the upgraded hydraulics (but I will be getting a new slave for the new clutch), drill mod has been done, insulated line running to the tranny, etc.
renxwar: If you find out what the source of the problem is anytime soon, I'd be really interested in hearing about it.

I have noticed in alot of the threads with people having issues they either messed with the master or just didn't install it correctly.
My car is a 99' & when I installed my clutch my master was working fine, so I left it alone. Removed my stock clutch & slave, my pilot bearing was still good too so we left it alone & then just installed the LS7/LS2 combo just like a OEM clutch. No suprises & very straight forward install. Bled it with a mityvac & haven't touched it since.

Not sure about high RPM dumps on N2O, just have not had negative feedback at all.... we have installed many, many LS7/LS2 combinations and have not had one come back. Not one. We have them in high H/P combinations with big shots of N2O and they are living just fine.
In fact that is the single performance clutch I recommend to my customers for their street / track cars. It is made by LUK. LUK designs and manufactures clutches for automobile manufacturers around the world, and have for a very, very long time. They are made with high quality components.
Hope that helps.

I got an LS7 clutch/LS2 flywheel kit, a new slave, and a new master cylinder put in my car last week....got a call from the mechanic saying that my setup doesn't work, so i went to investigate.....
My car goes into gear just fine with the car off, pressure is great on the pedal, a little stiff, but it's a brand new clutch. I can start the car, sounds fine, but then even with the clutch pushed all the way in, i cant get into ANY gear...it doesnt even grind, i just cant get it in gear.....the mechanic said he bled the system twice, and seems to think i got the wrong flywheel and wants to put the stock one back in....i'm thinkin NOOOO. I'm pretty sure it's something else, i just don't know what to tell him....all i've told him to do right now is get in and run part numbers to make sure i got the right stuff from Scoggin-Dickey....(p.s. the mechanic is a friend of my dad's and is cheap...not necessarily the smartest guy in the world when it comes to ls1's...he asked me more questions than i asked him about the initial setup....)
Can someone please tell me what they think could be wrong????

Tell him if he installed it correctly it just need to be bled more. This isn't the first time a simple minded mechanic tried to tell someone on this board this clutch doen't work in our cars.
I bled mine from the top with the mityvac, not the traditional method. Worked fine for me & I initially had the exact same problem as you.
