OS Giken Single and Twin Plate Clutches?

Oh that single plate supports ~430HP
#12
How much power are you making?
And what type of use does OSG describe for the types of clutches you're looking at? I would be surprised if they are streetable.
A low inertia single plate S2000 clutch that supports 430hp doesn't scream "street use clutch" lol.
My Exedy Hyper single was difficult to drive on the street, noisy AF, and lasted only 19K miles because I street drove it. It wasn't meant for street use. So I'm sure low RPM parking and traffic usage cost me some engine lifespan (thrust bearings) as well as clutch lifespan.
AMAZING clutch while I was using it on the track, though. Just not brilliant on the road.
Twin plates aren't street clutches (usually). But you need less clamp load...so maybe its better for your thrust bearings. And they may have better engagement qualities than a heavy single. The stock NSX clutch was twin plate...so...they can work, obviously.
Any clutch that's got more clamp load than OEM should definitely be paired up with an interlock bypass switch.
Either way...seems unnecessary unless you're making big power and torque.
There are proven "sport" clutch solutions that work.

+1 on the Exedy Hyper single clutch kit(ceramic disc) not being recommended for street use. It was too noisy, heavy pedal and the flywheel was too light(around 8 lbs I think).
I have a SOS Sport clutch(older one) on my 325WHP S2000 and it has low noise and close to OEM pedal effort. I went with their 11.5 flywheel too. I would check out the J's racing clutch slave cylinder if you want a lighter clutch pedal.

I found that OSG clutches are all basically push type which will require a conversion mechanism. I'm not interested in that to be honest.
My OEM clutch is still new and works well.

For now stock power enhanced by an Invidia 60mm TP. I do have a Vortech V2 kit that will be bolted on in the near future though. Didn't know about the Hyper from Exedy being how you described. I found Spoon clutch disc and clutch cover said to handle 30% more torque. How about that for street and track? Probably an ACT HD PP with stock disk for boost?

Seems like tried and true combination is ACT plate and OEM disk/everything else.
Your supercharged setup shouldn't need anything VERY special, as torque is still fairly low and linear.
Still do plan on the clutch interlock bypass switch, though, to be thorough, M8.

Interlock bypass...you USDM dudes have those as standard, correct?
#18
Shouldn't be slower on uptake. More clamp load means the spring will push the pedal up faster, if anything.
USDM cars have clutch interlocks. Meaning you need to push the clutch to start the car. You'd want to bypass that with a thumb operated switch.
You install a momentary switch that you can push. Then you start the car. That way, you don't have to push the clutch pedal down to start it.

I just put the ACT OEM combo into my ap2 along with an act 11lb flywheel and really like how it feels. Pedal is maybe a little heavier than stock but not bad by any means and it does grab nicely. The new flywheel is a must if you have an AP2 and are putting a clutch in. Totally transforms the car.

My ACT PP feels lighter than stock, but I guess that's mostly because my OEM setup was not greased correctly.
I'm went with the 8lbs ACT prolite flywheel because lighter is better and I don't have any regrets, it's a perfect setup
