Mike at GST recommended the ACT 6 puck to me and its worked great for me. stiff off the line, but you get used to it after a while.
definetly feel the difference

how'd you come up with such arbitrary numbers? They are really upside-down which would imply a turbo running out of breath before redline but any turbo that small isnt going to get you to 330whp on an STi, unless thats a small turbo on race gas, in which case you would be better off just getting a turbo big enough to take advantage of race gas 
Well anyhow, the Exedy(except hyper/multi-disc) and ACT use basically a heavier OE style 30% heavier P-plate with some combination of discs. The Exedy organic and ACT 6-puck arent really comparable since you can get either the ACT or Exedy with an organic or 6 puck, So the real question is do you want and ACT/Exedy organic or an ACT/Exedy 6-puck. Power wise my stock STI clutch didnt start slipping till after 330wtq (whp doesnt factor with clutches) and 50K miles on the clock. All in all the stock clutch works really well to hold tight till 100wtq over stock so I would like to keep it as close to that as I could, if you could get away with either of the of the organic ones out to 390 that would be my choice but that might be cutting it close. Between the two though I would go with Exedy since they are an OE supplier AND usually cheaper than their ACT equivalent. hope this helps
