Just curious what causes this condition that everyone mentions when you they hear what type of clutch you've got. I got my spoon 3 puck installed today, and I can't wait to see how it performs tonight. So far its easier on my leg than the ACT I had, but grabs just as hard if not harder.

 

the pucks (and lack thereof)

 

how much did you pay for the spoon clutch? if you dont mind me asking

 

spoon make a 3 puck???

anyways sppon clutches are not made to withstand the beating of Drag racing
good luck with it

BTW the chattering is the clutch pucks grabbing then slipping and grabbing again. kinda like wheel hop. its the $ you pay for ultimate grip.

 

Thanks for all the replies. I'm not a huge fan of drag racing so the clutch should work well for me.

About the price, I got a hook up because my ACT had a major defect, and I 've only had my swap since April. Hook Ups Import Tek exchanged the ACT for the Spoon one since that was all they had in stock for me, and sending it to ACT for warranty would take weeks.

 

All in all, tonight very happy with it. Coming out of turns, engagement is smooth and easy to drive.

 

what kind of clutch do you need it you like drag racing ? but also want to use it daily driven ?

 

act 6 puc will do great. and youll be able to chirp all the gears in low rpms.. and have it still streetable, with a nice heavy duty pp youll love it..<TABLE WIDTH="90%" CELLSPACING=0 CELLPADDING=0 ALIGN=CENTER><TR><TD>Quote, originally posted by toxicshit &raquo;</TD></TR><TR><TD CLASS="quote">what kind of clutch do you need it you like drag racing ? but also want to use it daily driven ?</TD></TR></TABLE>

 

will a lightweight flywheel do anny good ?

will you have a peg leg from the pressure of the clutch or will it just be a little stiffer than stock.

it will be alot stiffer then stock, i have the 6 puck with xtream pp, hard

And sprung/unsprung

Unsprung tend to chatter matter from the lack of springs

 

i have a clutchmasters stage 3 and i daily drive it, also it is great for drag chirps first thru third no problem

until you use it for 6 months and heat it up and the carbon slicks over, then ya loose that damn grip

Just curious what causes this condition that everyone mentions when you they hear what type of clutch you've got. </TD></TR></TABLE>There are several things that cause what is commonly referred to as "chatter".
1. First and most importantly are flexible engine and suspension mounts. Without them, chatter would most likely not be an issue. You wouldn't be able to handle the vibration on the street, but that is another story. It is the wind up and bounce back of the engine and suspension that you are really feeling when the clutch chatters. Usually stiffer mounts will reduce chatter.
2. Coeffiecient of friction. In general, higher friction = more severe chatter and more torque capacity. This is why stock automotive clutches, no matter the vehicle use a fairly low coefficient of friction.
3. Lack of Marcel - the marcel is the wavy spring metal between the disc linings. It allows the pressure plate to gradually engage onto the disc. Without it and a clutch tends to chatter. If the friction is real high then the marcel is no longer effective.
4. Number of pucks - More pucks = more chatter.
5. Spring center - On aggressive discs that tend to chatter, the springs allow for more wind up effect (much like the engine mounts) and the chatter is more severe. One of the most common misconceptions is that the springs reduce chatter which is totally false.

Example: Brent Rau's 7 second Eclipse which has about the most aggressive clutch we have in it still drives like a Sunday show car (as far as the clutch goes). This is because of the solid disc and solid mounts. There is no opportunity for the clutch to chatter since there is no wind up effect.

I'd like to know which ACT clutch you had and what problem you were having with it. You can drop me an email if you wish at dstarksen@advancedclutch.com or call the shop at 661-940-7555.

 

so, a non-sprung disc and solid mounts? Wouldnt that make for a fairly harsh ride? The engagement would be incredible would it not? I use an excedy clutch/flywheel combo. Not exactly happy with the clutch, but the fly wheel is excellent. The clutch is no better than stock in my opinion. Wish i had sprung a few more bucks for an ACT HDSS.

Oh well....Next time i guess.

The vibration would be terrible, but vibration is different from clutch chatter. Any clutch chatter would be gone, completely! The clutch would still engage fairly quickly (less pedal travel) but smooth and predictably since there is no engine/suspension windup. See what I am getting at?

Way back in the old days this is what vehicle manufacturers discovered when going to rubber mounts to smooth out engine vibrations . By limiting the friction and using a marcel in the disc, chatter was controlled. Disc springs were not designed to help with chatter. They were introduced to soak up torsional vibrations of the engine so the transmission gears wouldn't rattle and make noise. You can learn about this and more that you probably care to about clutches by reading the SAE (Society of Automotive Engineers) book called "Manual Transmission Clutch Systems".
