Well I decided to go the N/A route when I get my car instead of F/I (Mainly because I want to learn the car itself and how it reacts).

I've read that the stock clutch will hold whatever the stock Vortech and Comptech Kits will put down. Since After Market clutches are rated by Torque, I'm assuming that I wouldn't need to upgrade from stock (Seeing as N/A cars have very little).

I wouldn't mind having some extra grab, but I'm just afraid of what might happen to the Differential if I go with something with to much Clamp.

I'm not really asking what Clutch I should get, but if it would be O.K. to stay with a stock one.

I apologize if this has already been covered, please don't flame me too badly.

 

I might be wrong, but from my experience in Drag racing, you should be fine with the stock one, unless you intend to pull away hard, or slipping the clutch every so often. The problem with the paddle clutches is the enormous amount of strain on the drivetrain, such as gearbox, and diff. When I used to race my rx7, with a twin plate, I went through 2 boxes and 4 diffs, in 1 year. The other option is to get an organic clutch, which is a step up from stock, but is not as hard as a competition one.

 

I'm not really going to be Drag Racing at all.

 

Is there an organic clutch(non puck style) but holds more power?
What's the main difference between puck style and organic ones?
I know the puck styles shatter a lot, then why would they use one?
Does the puck style generally hold more power?

Sorry if it's a lot of questions, but any reply would be appreciated.

Organic clutches hold more power than a stock one, you should find pics of each one if you google the words.

The paddle one is the triangular shaped one, as you cans ee from the pic, its loads different from the stock one. The main diffirence is that an organic clutch still slips a bit whereas a paddle one is like an on and off clutch, thus the running gear will sustain the strain that used to be picked up by the slipping of the clutch.

I dont think its worth having a paddle in an NA S2, but probabaly I would if I ever go FI.

Paddle clutches are used mainly in drag cars, where traction is needed immediately and without any loss in power. But normally these cars use uprated gearboxes as well as diffs to cope with the power. There are a couple of cars which utilise a very strong gearbox from stock, like the Supra MKIV, and the Skyline which both use the Getrag 6 speed, but these are one off cars.

 

A stock clutch will barely hold, but it will hold. As long as your driving technique and clutch timing does not try to slip it between gears.

If you want to do a clutch, do an ACT pressure plate and stock disc.

No chatter, no buzz, and it will hold 550 HP.

 

Thank you Billman

 

Sorry to bother you guys,
will the ACT PP + OEM disc be sufficient enough to hold, say 250-280 ft-lb of torque(at the wheel)?
In other words, will it be enough for FI with roughly 400 WHP/280ft-lb ?
TIA

400 is under 550

 

I wasn't sure if it was literally 550.
Does that simple pressure plate upgrade provide that much clamping?
If that's true, then great, but I'm surprised that the cheaper(compared to other performance clutches) combo performs that well.
Any downside to this combo?

Not trying to be a jerk, just want to make sure if this is the right kit for me.
Thank you.
