Theres a place in Ft Lauderdale called clutch house....they can either do a custom setup for you or get you whatever brand you want. They are dealers for the major brands also. Their prices are good when i last delt with them

Or you can just run a act pressure plate with a cintered iron disc. call ram clutches for the disc. just run the heavy pressure plate not the extreme or anything like that. the cintered iron is very aggressive. not the funnest thing to get used to drive but i drive mine all the time on the street.

they modified it and sent it back in a week
its pretty streetable and it can hold 550footpounds of tq so it will last me a long time and I can beat on it.

Rob, get either a twin disc setup, or an A.C.T. Extreme single disc.

exedy is the racing division of Daikin. Daikin does over a billion $ in revs selling oem clutches/drivetrain parts to little known companies like GM F Toyota Mazda...
Daikin makes the rx7 pressure plates that others (ACT etc) mod and sell in the aftermarket.
Exedy is essentially the R&D arm of Daikin. i unfortunately know this because i spent too much time looking at clutch package options for my engine package that will running shortly.
options narrow greatly when hp heads north of 450 rw.
you either generally retain drivabilty (you can slip the disc) w an organic disc and then shred it or you give up drivability ( clutch is either engaged or not) and have a non-slipping clutch.
lousy trade off as you have already gathered...
i looked carefully at double discs, having run a Tilton during my road racing career. when i say looked carefully i mean i called and talked extensively to the engineering people at many of the clutch outfits.
i was already to buy an ACT XT pressure plate and organic disc but Judge Ito, my engine builder, said the pressure plate wouldn't hold my motor, something he had proved less than a week prior.
i talked to kevin fujioka, head tech guy for exedy in michigan. he pointed me towards the Exedy Hyper Single. it is a super cool design... very similar to a double disc in the sense that the cover is forged aluminum and sits on 6 pedestals. the forged cover allows exedy to alter the lever ratio and deliver a clutch that will hold 600 ft pounds of torque w near oem pedal pressure. the back of the pressure plate has cooling fins cast in it for air flow. because it is not encapsulated in a pressed steel cover you do get airflow. the flywheel is chrome moly steel something i really like. i have this thing about exploding cheesy aluminum flywheels and my legs. the disc weighs the same as oem so shifting is easy on the syncros. the disc has 6 big fat springs in it which should help the driveline. the material is cerametallic and their own patented material. kevin fujiyoka says that the engagement of the Hyper Single is much easier than their twin disc.
sounds pretty good......... we will see in a week assuming Judge Ito gets my motor together thursday which is looking probable. i did find a forum member in the U K that runs the Hyper Single. he said the pedal was virtually similar to stock...
i will report when i actually know.
the good news is that the package is reasonably priced. i bought mine thru morepowerracing everett wa for. get this, $887. (that of course includes the flywheel). you will need to talk to neil and mention my name to get that price. they advertise it at $987.
the bad news is there may not be many in the country and Exedy's U S facility in Mich ships them in by boat. 90 days...
exedy mich 734 397 6607 Tricia is the go to person.
i also hear good things about Jason's Spec package which would have been my next choice.
THE ABOVE WAS WRITTEN A FEW MONTHS AGO/////
as of july 8 i have over 600 miles on the clutch and it is absolutely AMAZING! very close to oem pedal and it engages smoothly! considering it is a 6 puck cerametallic that is way beyond my most optimistic hope.
all that and it holds 600 ft pounds.
wow do i love the Exedy Hyper Single.

that is a great post. lost of info and right to the point. Thanks for that. I have seen the hyper single on diff websites. did that come with a counterweight as well. and if so, how did u change it. there is this big deal with removing the front pully pn an FD because the fact hat u can drop the bearings inside.

as with other clutchsets that include an aftermarket flywheel it will be necessary to use an automatic transmission counterweight. call Ray Crowe at Malloy Mazda for the most competitive price. installation is as simple as any flywheel swap.

On the 13BT, I chose:
Z65-XT00 ACT Xtreme Series plate
Whatever ACT sells as "stock" 240mm disc
(and the optionals...)
600140 - ProLite - XACT Flywheel
Mazda automatic transmission counterweight N327-11-521A
Retained stock release lever, driver's pedal, hydraulic master and slave.
