Default clutch help

I'm currently building a 98 Supra, with a Titan Motorsports engine, 74mm turbo, 4" exhaust, FMIC, full fuel system, AEM engine management. I'm looking to get a max of 800hp on high boost, but a more reasonable 650hp at a regular boost level, used mainly as a weekend driver. I'm looking for a clutch/flywheel combination, that:
A: does not have extremely harsh engagement characteristics, i.e,"chatter" "on/off switch"
B: reasonable pedal feel
C: ability to handle power reliably i.e, 25k miles or more of regular street use.
D: reasonable pricing
any help will be greatly appreciated!!!

Do you mean the "800hp" (=680rwhp) that you posted above, or do you really mean 800rwhp? The reason I ask is because 680rwhp is a pitiful goal for a turbo as large as a 74mm on high boost...

If you really do mean 800rwhp (and not 800hp), then there is no clutch that meets all of your criteria. If you don't mind me asking, what line of work (or study) are you in? On the other thread you said "...i am a professional tech, i repair exotics,ferraris, lambos and porches..." - I guess they don't tell you how to spell Porsche when they work have you work on them. j/k lol ... either way, if you're really an automotive tech you should know there isn't such thing as a cheap, smooth, 800rwhp clutch. rofl

So you do mean 800rwhp and not 800hp?

Either way, you can't have it all. If it holds 800rwhp and it's smooth, it won't be "reasonable priced". If it's reasonable priced and smooth, it won't hold 800rwhp. Etc. Sorry to break the bad news to you, sir. Just pick any two of the three and I can probably find a product for you.

Sorry you're not listening. You can ONLY pick two. Period. In other words, if you pick smooth & 800rwhp I don't want to hear any restrictions on the price at all. Sorry, but that's the truth. If you want lies, just call someone trying to sell you one.

For about $2500 you can get a clutch that holds 800rwhp just fine, but it has a stiff pedal pressure and when it grips it grips hard. These are race clutches!!!! They're designed to handle abuse, like repeatedly dropping the clutch at 6K to launch in the 1/4, with SLICKS! ...they're NOT designed to ensure your g'friend doesn't smear her makeup while driving to the opera.

Your oem clutch will only hold about 400rwhp before it starts to slip...and if you drive aggressively, it won't hold 400rwhp for very long.

So which one do you want to give up on, slick? 800rwhp? smooth? ...or reasonably-priced? Just pick one to give up on (or two to use), and then don't mention it again. If you can do that, then I can help, and you can take my advice to the bank. In other words, I don't BS...I have my own Mkiv Supra TT and I've personally worked on at least a hundred Mkiv TTs (yep, I can provide references). I bet I've changed at least two dozen Mkiv TT clutches all by myself, and I've had four different clutches in my own Mkiv Supra TT. I have personal experience driving (and in most cases also installing) almost every clutch that's on the market for the Mkiv TT. Again, you can depend on no BS from me, but sometimes the truth can hurt.
