You will be nearing twin plate territory at that kind of power. If you want to try a single plate you'll need to figure out what flywheel is fitted if you have doubts about the gearbox.

If you have an NA gearbox it's no problem as you can remove a very small amount of material from inside the bellhousing and run a spacer on the starter motor and then run the TT sized flywheel & clutch.

A GOOD single plate clutch will hold up to 400KWs at the hubs no trouble at all - been there done that :wink:

Beware of southbend clucthes a lot of the Aussie guys have been having trouble with these & the responses from Southbend have been a little odd to say the least.

The ~$500 flywheels from Trademe work OK but will get hot spots & then harden in those ares making machining them after this very tricky - essentially a one time round flywheel it seems. (having said that you can use them again but it wont be a perfect situation).

The critical thing in holding the torque is the pressure plate & quality of the friction material, I've used an Extreme motorsport ressure plate in the past & found it to be pretty good with pressure on the foot but held up well to ~400rwkw when paired up with a six puck brass button type friction plate - not that hard to drive if you are good at ear,eye,foot coordination :wink:

The Z1 twin plate has some very good things but a couple of things you need to know:

Noise, it's not more or less silent like most OEM clutches, it will make a slight chirp when engaging & it will have a slight rattle while your foot is on the clutch pedal.
It will allow the engine to rev more freely but will also stall easier, the bite of the clutch is not what I would call "on or off" but it will give you some fun learning to drive with it :)

If the car is a fun car & not your daily drive then the Z1 twin plate is a cool bit of kit that works well, we have tested one to 500Kws at the hubs with no trouble, have one in my car & a third customer has one - all very happy with them.

If you wish to go with the Z1 clutch then consider getting in touch via PM as I can sort out a good deal on purchase price & shiping etc :D

As for the others I would go with Excedy long before the other brand even if the Excedy unit cost twice as much :wink:
