Clutch Input

[Mr.Jay]

What is the rating on the stage 1? As I remember asking ft86factory and they had it much lower than the 300tq you are at.

No rattles, at least not that i can hear. I will try to pay attention later when i drive home.

Yeah, that is what i was worried about, but ptuning assured me it was fine. Sure hope so. Even on the link i provided, which is their site selling it, they have it listed (TQ Capacity 319 ft/lbs.)

Although on ft86factory they have it for much less? Exedy Stage1

So i looked at Exedy site. here are the specs on their site for this clutch.
Clutch Torque 319
Torque Capacity at Wheels 203
Torque Capacity at Flywheel 254

Now i am really confused, sure hope i dont blow this thing out too fast, as i made sure to specifically pm and chat with ptuning about power output of my car and their recommendation was this clutch.

So who can clear this up? Since there are 3 torque numbers, which one is the one i should be most concerned with?

Thanks all!

Actually 4 sets of number as in the pas mag I was reading the listed tq rating for Exedy was listed at 275 with no mention is that was flywheel or not.

Hope the answers come to light before I'm turbo ready and best of luck to you guinea pig.. err friend XD

I'm going with the Exedy Stage 1 when the time comes. I used the Exedy Stage 1 in my boosted tC and it held up great.

Ptuning wouldn't recommend it if it weren't good and could handle the power without disrupting drivability.

At this rate, i have almost broke it in, so i will just run with it for now, and see how it does, as mentioned, guinea pig here, luckily was not too expensive, more the time to install it and the excruciating time to break it in....ugh.

i've actually been looking at the Spec stage 3, and will be picking one up shortly. It looked like it was less expensive on the site than the stage 2+, for some reason, but has a higher torque capacity (280lb/ft vs. 264 lb/ft)

It's a 6 puck. More like an on/off pedal compared to a full disk clutch. They just hold more power over full disks

What is odd is that a Stage 3+ is a full faced clutch, correct? (324 ft-lb)

Its not only full face/pucks, but also type of material, and pressure plate rating comes into play to say how much it holds.

Guys with heavy clutches. What do you do up hill in very slow traffic? If your killing 1500k rpms just on release is it a bit difficult?

No problems here. RPM does drop more now with the lighter flywheel but just feather it back. The car is light enough not to need any handbrake except for things like concrete car parks.

The one I would worry about is the Torque Capacity at Wheels. I am assuming that is ft/lbs which means this clutch will not hold up in most Forced Induction applications.

I believe this was discussed earlier in some other thread and I believe the consensus was the torque capacity is 203 ft/lb at the wheels for stage 1.

i went through this when i was shopping a clutch for my car. basically, ptuning quotes a much higher torque capacity (and have tested it to a much higher capacity apparently) than what exedy claims.

it's all very confusing, and depending on who you ask you'll get different answers on capacity and whether a flywheel is included. personally, i took the company that made it at their word and went with something rated for a higher capacity (act full face). it's only about $200 more.
