What clutch do you big power guys run?
I realize this isn't technically a Greddy question, but I figure this is the best source since there aren't too many people making big power on the 1.6.
Anyway, what clutch do ya'll use to hold up in the 250hp range on the 1.6? I am working on a t3 based setup and my goal is 250. I want an ACT. Does the heavy duty hold up (rated 200 TQ) or is the extreme the way to go. Thanks for the help.

My ACT XT should be here by the weekend. I'll let you guys know in a few hundred miles.
btw, this was my decision making thread from a few days ago.

Sounds like the XT is a winner. That's what I figured, but we put HD's in everything at work. Those are all 1.8's and I was afraid that the smaller 1.6 might run out of grip on me. Thanks for the input.

I got a stock 1.8 wheel for next to nothing and had it lightened.
I think I wrote this same thing yesterday: wouldn't you have a slightly heavier rotating mass that will absolutely not slip and transfer power, or a slightly lighter rotating mass that may rev faster, but potentially loose bite and slip?

Thanks again everyone. I'm just going to go with the 1.6 ACT XT with the street disk. It will take a little getting used to, but I like a stronger pedal pressure anyway. My wife doesnt drive the car too often, so it shouldnt be a big deal to have a manly pressure plate in the car.
Alright, do you guys run the regular street disk or the performance organic street disk with the XT PP? Gracias

i just hope my dual friction is acutally an improvement over the HD....
From the way a pressure plate works, it seems those centrifugal weights should improve the clamping force as the rpms rise, by forcing the weights to the outer edges this causes the PP to acutally clamp harder down.
My ACT HD was rated at 200tq, which is like a 33% increase ( i guesstimate the oem clutch can hold 150), new one is rated at 90% increase, so should hold closer to 280tq....but we'll see how effective this this is.
one thing i wish was available, the clamping forces of all pressure plates. OEM, ACT, Centerforce, Clutchnet, Competition, SPEC, etc. Then one could just choose a damn disc he's happy with and call it a day.

Alrighty then. I get everything ordered. ACT REALLY needs to update their website. Some of their part numbers have changed and they no longer make some of the stuff they used to. Makes things mighty confusing when you try to order from somewhere with old part numbers off the ACT website. I ended up going with the 1.6 extreme PP with the modified organic street disk. Aparently the only option of organic disk now from ACT without upgrading to 1.8 stuff. Thanks for the help. Now, I just have to get that bad boy in and broken in and then it's turbo time. It will be nice working on my car for a change.
