Modified Z06 clutch question
I have the good fortune to be shipping my 04 Z06 to Lingenfelter for a na 427 engine transplant, complete w/ long tubes. I'm thrilled, of course, but faced with a decision. Should I, must I, get a new clutch? My stock clutch has 13,000 very easy miles on it and is trouble free. The new engine will be putting out a minimum of 530+/530 at the crank. I am a staid and older fella who doesn't plan to race except for the occasional times when I run up against an absolutely overbearing Porsche or Beemer or tarted-up rice rocket that won't leave well enough alone.
Lingenfelter offers an Exedy single disk clutch assembly with aluminum flywheel as an option, but I fear that will be a considerably more aggressive set-up for my daily driver. I really like the easy-going take-up and feel of the stock clutch. Cost is not the primary issue, since at this point I'm already spending a good bit and don't want to be penny-wise and pound-foolish. My big concern is getting a set-up that takes away from the sheer pleasure and ease of driving the car.
Please give me your opinion--I appreciate the expertise advice of others.

Well your going from a clutch that was designed to hold 405hp to puting 530+ to it. It wont last long with all that hp. The LS7 clutch is a good one to look into if you dont race at all. It's heavy but will hold the extra power and wont be a pain to daily drive with. Either way you need a new clutch that will hold the extra power.

I'd suggest explaining your requirement for well-mannered streetability to LPE and ask for clutch alternatives with pro/con fleshed out. LPE has been through the process with many buyers like yourself and has earned their trust and admiration.

I only needed about two runs to redline after doing my H/C mods, to need a new clutch. Only 10k pretty easy miles on the stocker, and 475 RWHP. I don't recommend the Exedy clutch, or the LS7 at your new level. Lots of guys reporting problems with both at even lower levels than you'll have. I'm getting a Textralia clutch, and hoping for the best. Good luck, that should be a hell of a ride.

Only going off of what I have HEARD, the Textralia is turning out to be an excellent clutch. It is supposed to have great street manners, with a stock-like pedal feel, yet enough grip for higher HP regularly raced cars. For the amount of effort and labor that it takes to change out the clutch, it is $1,000 well spent (approx. $).
This is probably what I am going to use for my 430+RWHP Z06.

The textrila seems to be gaining in popularity............I may have to pay it a bit more attention............like the thought of "like stock pedal feel".

I have the Exedy dual disc setup and HATE it! It is not street friendly!
My Textrailia arrived Friday - Zgrip.
The Exedy would be a great setup IF the car wasn't driven much on the street. It is either on or off with no slipage - too little gas, it stalls - too much the wheels spin ( there is no sweet spot) and forget getting stopped on a hill. Pedal pressure is aboput 15 % more than stock - which really isn't too bad. There is alot of clutch chatter. The clutch has approximately 1200 miles on it. Hope this helps.
