i'm trying to find out what could possibly be wrong but I'm stumped.
I installed this setup Saturday(230miles ago)
When I take off from 1st gear I REALLY have to rev the car to keep it from bucking. i can deal with that as I'm told it will be the case with the lighter fw.
But if I dont get the RPMs high enough I get a horrible repeating clunk noise from directly under the console area. I can feel it in my arm and it's loud. It really feels like the trans isn't attached somewhere but I checked everything and it's all tight. Do I really just have to rev to 3-35k to take off slowly? If that's the case I'm gonna need to put my stock flywheel back in:(

yes, with lighter flywheels you need to keep the revs up higher to put the car into 1st gear. if you don't like it, put the OEM flywheel back on.

How light is it??
My ACT flywheel is 13.8 lb I think. A little too light. But high revs aren't the answer. imo It can make things worse. Practice letting the clutch out at low rpm's. It takes a while. Is it sprung?

so you have a sprung stage 1 clutch and which exact flywheel?...did you go with one of the sub-10lb models or the 13-14 lb models?...

I'm not sure about the weight.
The clutch is sprung.
The flywheel is from autospeed performance.
unkadave - if I dont rev the car high enough 3k-4k it bucks like mad.
I think I'm gonna put the stock flywheel back in.

I will not discount what you say. But I went thru the same thing. For me letting the clutch out at idle works better than revving it. You have to mind meld with the clutch and throttle. ;)

But if you've tried. Something else is going on. I got noth'n in that area. Is it one of those 3-4 pucks? I have heard to stay away from them. I'd sure solve it quick. jmhot

This is bodhi on my brothers name.
The clutch is solid disc not a puck.
I found out the flywheel weighs 11.9 lbs.

That is really- really light. May be the problem. Are you getting missfire CEL's?

I think maybe something else is wrong? My Exedy lightweight flywheel was only a little over 12, and I don't experience those symptoms...Reving around 2K and gently letting out is very smooth.

12 lbs is just about the limit as far as flywheels go. You have the possibility of throwing CELs, and any lighter than that and you're almost guaranteed to throw a CEL.

although as I recall, the misfire CEL shouldn't put your car into a limp or safe mode. It's just an annoyance to clear, plus you won't know if your car runs into any other problems.

I remember reading something like that, somebody correct me if I'm wrong?

No you are right. My 13.8lb ACT flywheel threw CEL's like crazy. You almost need a balanced crank and flywheel to get away from it. Or an EcuTek fix. ;)

gotta love ECUTEK, can't wait to get one for my car. :D :banana:

Correct. I throw CELs randomly, but not so frequently to pull it back out.

....it sounds like something wasn't re-assembled correctly/forgotten/missed.....

recheck EVERYTHING.

:D

I don't have any cels and the car runs great.
I know it sounds like something wans't reassembled but I did recheck everything.
I am stumped.

I was kid'n with Uncle Scotty. If he says something was assembled wrong it is probably the case. Did you say you did the install?

Yeah I did the install.

....didya get goop all over the clutch disc or the flywheel????

These are done all the time and your symptomes are atypical....

No I didnt use anything but clean, dry tools.
After driving it today it definitely only does this when the clutch needs to grab hard.
Taking off and downshifting.
Is there any chance this will break in and fade away? Im at 330 miles now.
I went over every nut and bolt todaya gain and everything is tight. Everything!

Down shifting???? That is unusual. imo

My 13.8 ACT fly wheel did smoothe out. But I put in a Axis 2,5 Short Block with mods. Now it pulls away form a dead stop like buttah.

The disc and PP and flywheel DO have th get all happy with eachother....I'd give it at least 1k miles....

Ive been taking it really easy on the new setup for the break-in. The little paper that came with the clutch said to break it in for 500 miles. Should I start driving it a little harder to introduce the new components to each other(make them all happy with each other:))

Thanks for all the quick replies.
I know this thread is probably getting old quick but it's frustrating when you spend 8 hours and a few hundred dollars to FIX your car only to make it worse then it was.
:discouraged:

follow directions ;)

yes to both, old thread or no :D
ecutek takes care of my crank position issue. my flywheel was the racing model, 9lbs is fun but requires extra lovin'...
