does anybody know what the clamp load (lb) is on stock clutch? im planning to go with FP green n wondering if the stock clutch would hold up. some said yes, some said no. i only have 6000miles on the clutch, so i was wondering if i could just get by with the stockies. thanks for the inputs guys

 

2900lbs

 

you can do it. its not recommened, but the clutch will be toast in a couple thousand miles. why not get a nice act unit that isnt too expensive and will hold the power..

just my .02

 

Laf, no way. It's 2200lbs. 2900 is the clamp load of an ACT HDSS - WAYYYYYYY stiffer than stock.

I doubt anyone said the stocker will hold the power of an FP Green. Maybe they said it will hold without slipping for regular driving, but if you do any racing, it's going to wear out very quickly and not be able to hold the torque. Regardless, though, don't worry about changing it until it goes out, but be sure to have your next clutch ready.

 

thanx for the inputs guys. this car is a daily driver, i don't race often and i don't launch the car at all... do a lot highway driving. racing from rolls should be ok i guess. i don't wanna risk my tranny because of stock clutch won't be able to handle the power, thats my only concern.

 

2200? thats not bad at all... exedy twin plate is only 2205

 

drive it till it goes, it will take some time on the street when not abused heavily...

 

I hope you're running alky with the LT!

 

hey james

 

i guess thats what am i gonna do. but is it too much stress on the tranny itself when the clutch is too weak?

 

haha hey man...i'm actually considering going this route myself...i've got some time though so maybe ill end up strapping on something different.

I actually agree with ultimate about your clutch...you're gonna have to replace it soon if you put the green on so either abuse the hell out of it now and replace it soon, or just know it will probably start slipping soon after the turbo install and tune.

 

sorry the twin plate is 2920..

Look at it like this man, you can risk it and get stranded 2 months later with a slipping clutch, or you can wait till you have enough money for a clutch and a turbo buy both drive it when it goes bad you will be like "wow i sure am glad i already bought this clutch" i would never in my wildest dreams do any more boosting on a stock clutch that the car comes stock.. i think many will agree with me.

(PS this just happened to me last year)

 

where did u get this info from? o yeah the stock 16g pushs 55lb/min too.

 

No such thing as highway "racing." Anyway, it doesn't sound you'll be using your 20g anyway, so your clutch will probably last a while.

I'm not sure what you are talking about when you say you don't want to risk the tranny because of the stock clutch. Why in the world would a weak clutch be a risk to your trans? Mitsu specifically put in a weak clutch on Evos to reduce the frequency of drivetrain-related failures. The clutch is a wear item, so it is not covered under warranty, whereas drivetrain parts are covered for a long time.

If anything, you should be worried about how a very strong aftermarket clutch would risk damage to the trans, not the other way around.

 

Twin plate clutches have a lot more disc surface area to grip though. That's why they don't need very high clamping pressure.
